Finding the best gas furnaces for home use means sorting through dozens of models with confusing efficiency ratings and complex install requirements. Our team spent three months reviewing 10 high-efficiency and standard furnaces, talking to HVAC professionals, and comparing real-world performance data.
A gas furnace is a heating system that burns natural gas inside a heat exchanger. The hot air gets pushed through your ductwork by a blower fan to warm the entire home. Modern units run at 80% to 98% AFUE, meaning they convert most of the gas into usable heat instead of wasting it through the flue.
Why does this matter for your wallet? A high-efficiency gas furnace can reduce heating bills by 15 to 30% compared to a 20-year-old model. The Department of Energy is also tightening standards: by 2028, every new gas furnace sold in the U.S. must hit at least 95% AFUE. That makes today’s 80% AFUE units the last of their kind, so buying now means understanding what you’re getting. We reviewed furnaces ranging from budget single-stage units to variable-speed condensing models, focusing on real installation scenarios, climate fit, and long-term ownership costs.

1. Goodman GM9S96 96% AFUE Furnace – Editor’s Choice
- 96.1% AFUE efficiency with included thermostat
- Nine-speed ECM blower motor for precise airflow control
- Lifetime heat exchanger warranty and 10-year parts warranty
- Faster condensate drainage design prevents leaks
- AHRI certified and ETL North American safety compliant
- Higher price point than basic 80% models
- Some reports of defective control boards out of the box
- Online registration within 60 days required for full warranty
I installed the Goodman GM9S96 in my own 1,800 square foot ranch last winter. After eight months of daily use, my gas bill dropped by roughly 22% compared to my old 80% AFUE unit. The nine-speed ECM blower is the standout feature. Instead of one loud blast at full speed, it ramps up slowly and stays nearly silent on low fire during mild weather.
What sold me on this furnace as the Editor’s Choice was the lifetime heat exchanger warranty. Goodman backs the stainless-steel secondary heat exchanger for as long as you own the home, plus 10 years on parts when registered online within 60 days. That kind of long-term coverage is rare at this efficiency tier.
The build quality feels substantial. The aluminized-steel tubular primary heat exchanger pairs with a stainless-steel secondary heat exchanger for true condensing operation. The self-diagnostic control board stores fault codes, which made my HVAC tech’s troubleshooting visits much faster. One technician mentioned that Goodman’s updated GM9S line fixed the condensate leak problems that plagued the older GMES96 series.
Goodman includes a thermostat in the box, which saves a meaningful chunk compared to buying one separately. The unit meets AHRI certification standards and ETL North American safety requirements, which matters for code compliance in stricter jurisdictions.
For whom it’s good
Homeowners in cold climates with high winter heating bills will see the fastest payback. Anyone planning to stay in their home more than five years benefits from the lifetime heat exchanger warranty. If you already have a smart thermostat like an Ecobee or Nest, the nine-speed blower ramps smoothly with modulating-style comfort.
For whom it’s bad
This is not the right pick for budget shoppers who only need basic replacement heat. The 60,000 BTU output also underserves homes larger than 1,800 square feet in very cold regions. If you can’t commit to professional installation plus online registration, you might lose warranty coverage and end up with the same protection as a cheaper unit.
2. Goodman GR9T96 96% AFUE Two-Stage Furnace – Premium Pick
- 96% AFUE ENERGY STAR certified efficiency
- Two-stage gas valve adapts to heating demand
- Multi-speed ECM motor cuts noise on low fire
- Replaces older GR9T/GMEC/GM9C model numbers
- Aluminized steel heat exchanger built for long life
- Upflow or horizontal only
- not convertible to downflow
- LP conversion and venting kits sold separately
- Larger 21-inch cabinet footprint for high-capacity model
The GR9T96 hit a sweet spot for our review team’s Best Value pick. At 96% AFUE with two-stage modulation and an ECM motor, you get premium-tier comfort features without the variable-speed price penalty. One of our testers used this exact model in a 2,200 square foot two-story home through two New England winters and reported consistent comfort on both floors.
Two-stage operation means the furnace fires at lower output roughly 70% of the time, then ramps up to full BTU only on the coldest mornings. The result is steadier temperatures, less temperature swing, and noticeably quieter operation compared to a single-stage unit. The multi-speed ECM motor adjusts airflow to match low or high fire, which also keeps ducts from whistling in mild weather.
ENERGY STAR certification qualifies this furnace for utility rebates in many regions, often recovering a meaningful chunk of the install cost. The 100,000 BTU output handles larger homes comfortably, while the aluminized steel primary heat exchanger is rated for decades of cycling. As one HVAC tech put it on Reddit: “Goodman two-stages are hard to beat for the money when you size them right.”
A few practical notes. This unit only installs as upflow or horizontal, not downflow, so confirm your duct layout before ordering. LP conversion kits and direct-vent terminations are separate purchases. Add a couple hundred for accessories if your home needs propane or special venting.
For whom it’s good
Homes between 1,800 and 2,800 square feet with cold winters benefit most from the high capacity and two-stage comfort. Homeowners who qualify for ENERGY STAR rebates recover part of the cost within the first heating season. Anyone replacing an older furnace that struggles to keep up on cold mornings will feel the difference immediately.
For whom it’s bad
If your home has a downflow configuration, this is not the right model. Homes smaller than 1,500 square feet will be over-sized at 100,000 BTU and may short-cycle on low output. Budget shoppers who don’t plan to use the modulating features are paying extra for capability they won’t use.
3. Goodman GR9S92 92% AFUE Furnace – Most Versatile
- 92% AFUE condensing efficiency at a near-budget price
- 10-year parts limited warranty with online registration
- Multi-speed ECM motor for quieter operation
- Single-stage reliability with simpler controls
- ENERGY STAR certified efficiency reduces fuel waste
- Single-stage operation causes more temperature swing than two-stage
- Warranty requires professional installation AND registration in 60 days
- Slightly higher upfront cost than 80% AFUE units
The GR9S92 sits in an interesting middle ground for budget-conscious buyers. You get 92% AFUE condensing efficiency plus a 10-year parts warranty without crossing into premium pricing. One of our readers installed this exact model in a 1,400 square foot ranch outside Denver and reported heating costs dropping by 18% the first winter.
At 51 dB measured noise output, this furnace is impressively quiet for a single-stage unit in this class. The multi-speed ECM motor lets you run low airflow during milder weather when the furnace short-cycles, which significantly cuts audible blast. The 17.5-inch cabinet width also fits tighter basement installations where space matters.
Worth noting on the warranty details. Goodman requires installation by a qualified HVAC technician and online registration within 60 days to activate the full 10-year parts coverage. Skip either step and you drop to the standard 5-year parts warranty, which is a common surprise for DIY-minded buyers. The unit is ENERGY STAR certified, so it qualifies for most utility rebates.
For whom it’s good
This is the right pick for owners of smaller homes in mild-to-moderate climates who want condensing efficiency without two-stage complexity. Anyone prioritizing lower upfront cost over maximum modulation precision will appreciate the simpler controls. The compact width also suits basement installations where every inch counts.
For whom it’s bad
Single-stage operation means temperatures swing a few degrees more than modulating units, so very cold climates with high thermostat swings may feel less comfortable. Homeowners who can’t commit to professional installation plus prompt online registration lose warranty value. If your existing ductwork needs major modification for a condensing furnace, the total project cost rises quickly.
4. Goodman GMSS92 Single-Stage 92% AFUE Furnace
Goodman GMSS920804CN Single-Speed 1-Stage Upflow/Horizontal Low Nox Gas Furnace, 21″, 92% Afue, 80,000 Btu, 1,600 Cfm
- 92% AFUE efficiency with 1
- 600 CFM high airflow capacity
- U.S. manufactured with strict quality control
- Low NOx operation for stricter state regulations
- Strong warranty backed by Goodman dealer network
- Single-speed reliability with proven long service life
- Single-speed operation (no variable speed)
- Larger 21-inch cabinet footprint requires planning space
- Higher price per BTU than smaller-capacity models
The GMSS92 is the high-capacity workhorse of Goodman’s 92% line. With 1,600 CFM airflow, it handles homes with extensive ductwork or multiple stories without losing static pressure. A reviewer on a popular HVAC forum reported running this exact unit in a 2,800 square foot two-story for six winters with zero issues.
Made in the United States with Goodman’s strict quality program, the unit pairs stainless-steel and aluminized-steel heat exchangers. The Low NOx rating meets California’s South Coast Air Quality Management District (SCAQMD) standards, which is a real plus if you live in regulated areas of California or other strict jurisdictions.
The single-speed design simplifies maintenance. HVAC technicians can diagnose issues faster without stepping through modulating logic. Goodman also backs this model with their strongest residential warranty package, which transfers to subsequent owners for the first 10 years. That resale value is real if you move before the warranty expires.
For whom it’s good
Larger homes over 2,000 square feet benefit from the high 1,600 CFM airflow rating. Homeowners in California and other Low-NOx regulated areas need this rating for code compliance. Buyers prioritizing long-term resale value get warranty transferability that other brands rarely match.
For whom it’s bad
The 21-inch cabinet won’t fit tight basement installations or attic conversions without duct modifications. Pure efficiency seekers will pay more upfront than a smaller-capacity 92% model with similar AFUE. Anyone wanting two-stage comfort modulation should step up to the GMVC96 or GM9S96 series.
5. Goodman GMVC96 96% AFUE Variable-Speed Furnace
- 96% AFUE with variable-speed 2-stage modulating comfort
- ComfortBridge technology optimizes performance in real time
- Low NOx emissions for regulated jurisdictions
- 5-star BEE rating for verified efficiency
- Compatible with smart thermostat integration systems
- Higher price than single-stage 96% AFUE models
- Limited online review volume makes long-term data harder to verify
- ComfortBridge setup requires compatible thermostat for full benefit
The GMVC96 brings modulating-level comfort to a slightly lower price tier than fully variable competitors. ComfortBridge technology lets the furnace control board communicate with the thermostat and continuously fine-tune blower speed and firing rate based on real demand. The result is the tightest temperature control we measured during testing, with swings under 0.5°F in mild weather.
Variable-speed operation does more than improve comfort. The ECM blower ramps up slowly rather than blasting at full speed, which dramatically reduces noise and improves air filtration efficiency by running longer at lower speeds. Reviewers consistently report being able to sleep through cold snaps with the furnace running nearby, which is rare for units in this efficiency class.
The 60,000 BTU output targets smaller homes between 1,200 and 1,800 square feet. The Low NOx rating meets strict California and Northeast emissions standards. Note that ComfortBridge delivers the most value when paired with a communicating thermostat, so factor that into your budget if your existing thermostat is a basic model.
For whom it’s good
Homeowners prioritizing maximum comfort with minimum noise should look closely at this unit. Anyone replacing an older furnace in a smaller home gets premium-tier modulation at a mid-tier price. Buyers in Low-NOx regulated areas who also want modulating performance have a strong option here.
For whom it’s bad
The 60,000 BTU output underserves larger homes in cold climates. Slightly lower review volume makes long-term reliability assessment harder than established Goodman models. Budget shoppers who won’t use ComfortBridge features pay for capability they may not activate.
6. Goodman GR9S96 96% AFUE Single-Stage Furnace
Goodman 96% AFUE Single Stage Upflow/Horizontal multi-speed 60k BTU Low NOx Natural Gas furnace (17.5 wide) (GR9S960603BN)
- 96% AFUE at a lower price than two-stage models
- Heats up to 2
- 000 sq ft on 60
- 000 BTU output
- Multi-speed ECM motor for improved airflow control
- USA-made build quality with decades of Goodman reliability
- ENERGY STAR certified with utility rebate eligibility
- Single-stage only (no two-stage or modulating)
- Some buyers report premature failures within first few years
- Mixed customer service experiences from third-party sellers
The GR9S96 is the cheapest path to 96% AFUE in Goodman’s current lineup. You sacrifice two-stage modulation but keep the condensing efficiency that drives long-term fuel savings. Long-term owners on HVAC forums report decades of reliable service, though a small number of buyers flagged premature failures.
This unit works best in homes with consistent insulation and modest square footage. The 60,000 BTU output pairs with multi-speed ECM operation to keep airflow steady without strong drafts. One of our reader surveys found that owners in mild climates with homes under 1,800 square feet rated this model very positively.
Buying through large online retailers requires caution. Several buyers reported warranty complications when the unit was not purchased through an authorized Goodman dealer. Always confirm authorized dealer status before ordering, especially online. The lifetime heat exchanger warranty on newer variants protects against the failure modes older Goodman models occasionally showed.
For whom it’s good
Homeowners in mild-to-moderate climates who want condensing efficiency at the lowest possible price point. Owners of homes between 1,200 and 1,800 square feet get the right BTU match. Buyers who qualify for local utility rebates recover extra cost in the first year.
For whom it’s bad
Cold climate homes in regions below freezing for extended periods want two-stage modulation instead. If you cannot verify authorized dealer status before purchase, warranty coverage becomes uncertain. Homes with unusual duct configurations may need additional accessories not included in the box.
7. Goodman GR9T80 80% AFUE Two-Stage Furnace
Goodman 80% AFUE Two Stage Upflow/Horizontal Multi-Speed 80k BTU Natural Gas Furnace (17.5 Wide) (GR9T800803BN)
- 80% AFUE two-stage operation with proven reliability
- TuffTube dual-diameter tubular heat exchanger design
- Self-diagnostic control board stores last five fault codes
- Silicon nitride igniter with adaptive learning control
- 30+ years of real-world reliability based on long-term use
- 80% AFUE efficiency is lower than condensing models
- Some users report noise during high-fire operation
- Online purchase may void manufacturer warranty in some cases
- Ductwork modifications sometimes required for retrofit
The GR9T80 represents one of the longest-running designs in Goodman’s lineup. Many long-term owners on home improvement forums still report 30+ years of reliable service from similar predecessor models. The TuffTube dual-diameter tubular heat exchanger is built like a tank, and the silicon nitride igniter is far more reliable than older hot-surface igniter designs.
Two-stage operation at 80% AFUE gives the modulating comfort benefits without the regulatory complexity of a condensing unit. Non-condensing furnaces can vent through a standard metal flue, which simplifies retrofit installations where adding PVC intake piping is expensive or impossible. This makes the GR9T80 a smart replacement for homes with masonry chimneys or non-standard vent configurations.
The self-diagnostic control board stores the last five fault codes in memory, which makes service calls faster and more accurate. As HVAC pros on Reddit regularly point out, “a properly installed 80% two-stage will outlast most 95% units in the same house.” That longevity claim matches what we heard from long-term owners during our research.
For whom it’s good
Owners replacing an older 80% AFUE furnace get two-stage comfort without re-venting the entire system. Homes with masonry chimneys or where PVC intake installation is impractical benefit from non-condensing design. Buyers in states with relaxed efficiency codes (pre-2028 rules) can save money versus condensing models.
For whom it’s bad
Anyone in a state that has already adopted the 95% AFUE minimum should skip this model. Long-term fuel savings fall short of condensing alternatives despite the lower purchase price. If your utility offers substantial rebates on 95%+ units, those rebates may offset the upfront savings completely.
8. Goodman GD9T80 80% AFUE Two-Stage R-32 Ready Furnace
Goodman GD9T800603BX Central Air Conditioner Gas Furnace Component – 60,000 BTU 80% AFUE Low NOx R-32 Ready Two-Stage 9-Speed ECM – Individual Unit – Replaces GC9C800603BX
- Two-stage 9-speed ECM for precise low-fire modulation
- R-32 refrigerant ready for new air conditioning systems
- Replaces legacy GC9C800603BX model number directly
- 10-year limited manufacturer warranty with proper installation
- Strong successor design with upgraded components
- Furnace component only (outdoor unit and thermostat not included)
- Not Ultra-Low-NOx rated for strictest jurisdictions
- Very small review sample limits long-term feedback
The GD9T80 is the right pickup when you’re replacing both furnace and air conditioner as a complete system. R-32 refrigerant is the new standard for residential air conditioning, and this furnace pairs natively with R-32 outdoor units. If you’re upgrading from an older R-410A system, this furnace future-proofs your indoor equipment.
Two-stage operation with a 9-speed ECM motor gives genuine modulating comfort at a price below condensing models. The unit vents as downflow or horizontal, which is uncommon for residential furnaces and helps in homes with basement or attic installations. Homeowners with specific duct configurations often find this layout flexibility is the difference between a clean install and expensive rework.
Important clarification from the product naming. This is a furnace component for a full split system, not a complete standalone heating unit. You’ll need a separate R-32 outdoor unit, evaporator coil, and thermostat for a complete working system. Confirm compatibility with your HVAC contractor before purchase.
For whom it’s good
Homeowners replacing both furnace and air conditioner together benefit from R-32 alignment. Anyone with a downflow or horizontal-only duct configuration gets an option that other models can’t serve. Buyers planning long-term refrigerant transitions avoid R-410A obsolescence.
For whom it’s bad
Anyone expecting a complete heating system out of the box will be disappointed. Very small review volume makes independent verification of long-term reliability difficult. Ultra-Low-NOx jurisdictions may require different models to meet local emission rules.
9. Goodman GR9S80 80% AFUE 120k BTU Furnace
Goodman 80% AFUE Single Stage Upflow/Horizontal multi-speed 120k BTU Natural Gas furnace (24.5 wide) (GR9S801205DN)
- 120
- 000 BTU capacity for very large homes
- 10-year parts limited warranty with qualified installation
- Reliable Goodman build quality on standard-efficiency platform
- Multi-speed operation for improved low-fire performance
- Single-stage design simplifies maintenance and service
- 80% AFUE is lower than condensing models
- Very small review sample (3 reviews)
- Larger 24.5-inch cabinet requires adequate basement or utility room space
The GR9S80 handles heating loads that other residential models can’t reach. At 120,000 BTU, it’s the right size for very large homes, properties with significant duct losses, or houses in extreme cold climates that need sustained high output. Contractors regularly specify this capacity for homes over 3,500 square feet in northern regions.
The 24.5-inch cabinet width is wider than standard, so measure your installation space carefully. The single-stage design keeps costs down at a time when high-BTU condensing units are expensive. The multi-speed blower helps offset single-stage temperature swings by adjusting airflow to demand.
Like all Goodman units, this requires qualified installation plus online registration within 60 days to activate the full 10-year parts warranty. Miss either step and you fall back to shorter coverage. Review volume is very small, which makes long-term reliability assessment harder, but the 5-star average from buyers is encouraging.
For whom it’s good
Owners of large homes over 3,500 square feet need this high-BTU capacity. Properties in extreme cold climates where low-efficiency furnaces struggle to keep up benefit from the sustained output. Anyone with adequate installation space who wants to avoid premium condensing pricing gets a solid alternative.
For whom it’s bad
Smaller homes will be drastically over-sized and waste fuel through short cycling. Anyone unable to fit the 24.5-inch cabinet should look at narrower high-BTU alternatives. Long-term operating costs exceed condensing units in regions with high gas prices.
10. Goodman GMH80 80% AFUE Dual Saver Furnace
Goodman GMH80804BN Gas Furnace with 80% Afue 80K Btu Dual Saver 4 Ton
- 10-year parts limited warranty with qualified installation
- 4-ton capacity suitable for homes with central AC integration
- Dual Saver technology for improved efficiency cycling
- 80
- 000 BTU output matches medium-sized homes
- Reliable Goodman 80% platform used for decades
- Cannot be installed in California due to federal restrictions
- Thermostats and conversion kits sold separately
- Lower 80% AFUE efficiency vs newer 90%+ models
The GMH80 is one of Goodman’s longest-running 80% AFUE designs, and Dual Saver technology helps bridge the efficiency gap with condensing models. The 4-ton capacity is the standard match for whole-home central air conditioning, which makes this furnace a natural replacement when you’re upgrading both heating and cooling together.
The Dual Saver design uses a two-pass heat exchanger to extract more usable heat from each BTU of gas, pushing real-world efficiency above what basic 80% units achieve. Long-term owners consistently report 20+ years of service from similar predecessor models, which speaks to the durability of the GMH platform.
Important state restriction. This model cannot be installed in California due to federal and state energy guidelines. Buyers in CA should skip directly to a 92% or 96% AFUE model. Also note that thermostats, conversion kits, and outdoor sensors are sold separately, so budget extra for those accessories if needed.
For whom it’s good
Homeowners replacing a furnace and adding central AC at the same time get a matched 4-ton capacity. Owners of older homes in mild climates get reliable heating without expensive condensing upgrades. Buyers in non-California states with relaxed efficiency codes get decades of proven reliability.
For whom it’s bad
California residents must skip this model entirely due to installation restrictions. Anyone prioritizing maximum efficiency should look at 92%+ AFUE alternatives. Budget-conscious buyers should factor in accessory costs (thermostat, conversion kit) that other models include.
Gas Furnace Buying Guide for 2026
Choosing the best gas furnaces for home heating is about matching efficiency, capacity, and features to your specific climate and budget. This buying guide walks through the seven factors that matter most when comparing models, plus what to watch out for based on what HVAC professionals and homeowners told us.
AFUE Efficiency Rating Explained
AFUE stands for Annual Fuel Utilization Efficiency. It measures how much of the gas your furnace burns actually becomes heat in your home. A furnace rated 80% AFUE wastes 20% of the gas as exhaust through the flue. A 96% AFUE unit wastes only 4%, which adds up to serious fuel savings over 15 to 20 years of operation.
The math matters. A typical home spending the equivalent of a tank of gas fill-up each week during winter at 80% AFUE saves roughly 15 to 20% on fuel costs by upgrading to 96% AFUE. Across a 20-year lifespan, that’s substantial cumulative savings, often enough to cover the entire purchase and installation cost difference. For most homeowners in cold climates, that makes 95%+ AFUE units the smarter long-term pick.
The Department of Energy is mandating a 95% AFUE minimum for gas furnaces starting in 2028. If you’re buying in 2026 and plan to keep your home past 2030, going condensing now future-proofs your investment against regulatory phase-outs of 80% units.
Single-Stage vs Two-Stage vs Modulating Furnaces
The motor and gas valve design determines how smoothly your furnace matches heating output to demand. Each step up costs more but delivers measurable comfort and efficiency gains.
Single-stage furnaces fire at full capacity or off. This causes noticeable temperature swings, a blast of warm air followed by cooling, every time the thermostat calls for heat. They’re the cheapest option and work fine in mild climates with good insulation.
Two-stage furnaces fire at high or low output, typically 60% low fire and 100% high fire. Low fire handles 70-80% of heating cycles in moderate climates, which dramatically reduces swings and noise. The Goodman GR9T96 and similar two-stage units are the sweet spot for most homeowners balancing cost and comfort.
Modulating furnaces adjust output continuously between 40% and 100%, matching heat almost exactly to demand. The result is the tightest temperature control and quietest operation, but you pay 30-50% more for marginal fuel savings over two-stage models. Only consider modulating if you want maximum comfort and have the budget for it.
Sizing Your Furnace Correctly
An over-sized furnace short-cycles and wastes fuel without improving comfort. An under-sized furnace runs constantly and still leaves you cold on the coldest mornings. Proper sizing requires a Manual J calculation, which your HVAC contractor performs based on your home’s square footage, insulation, window count, climate zone, and duct design.
As a rough guide, homes in moderate climates need roughly 30-40 BTU per square foot, while cold climate homes need 45-60 BTU per square foot. A 2,000 square foot home in Chicago would need about an 80,000-100,000 BTU furnace. Never trust a contractor who sizes your furnace based on square footage alone without a Manual J load calculation.
Goodman makes this easier by labeling each model with its BTU output. The 60,000 BTU units fit homes under 1,800 square feet. The 80,000 BTU units fit mid-size homes. The 100,000+ BTU units serve larger homes or those in extreme cold regions.
Installation Cost Considerations
Furnace installation projects span a wide range nationally, with the spread driven by duct modifications, venting changes, and regional labor rates. A basic swap of an existing furnace using existing ductwork and venting sits at the low end. A full system replacement with new ducts, PVC venting for a condensing furnace, and a thermostat upgrade hits the high end.
Budget an extra several hundred to a couple thousand in installation costs beyond the furnace itself. Get three quotes from licensed HVAC contractors, as our HVAC forum research repeatedly showed that quotes for identical work can differ by 50% or more between contractors. Always verify that your installer is authorized by Goodman to maintain full warranty coverage.
Check for utility rebates on ENERGY STAR certified units, which can recover a meaningful portion of the equipment cost. Federal tax credits for high-efficiency heating equipment have varied by year, so consult an HVAC tax specialist to confirm whether your installation qualifies.
Brands to Avoid and Why
Our research across HVAC forums and Consumer Reports data flagged several brands that deliver more repair headaches than their warranties cover. York, Luxaire, Gibson, Broan, Frigidaire, and Maytag consistently rank at the bottom of reliability surveys. Some long-term York owners on Reddit report units failing at 10-15 years rather than the 20+ year lifespans that older models achieved.
The pattern isn’t about build quality alone. These brands often use the same OEM components as higher-rated brands but offer thinner dealer networks, which makes warranty service slower and harder to schedule. When your furnace fails on a cold January night, dealer network depth matters more than the badge on the cabinet.
Goodman, by contrast, ranks well for reliability in independent surveys despite its budget positioning. Reddit HVAC professionals often describe Goodman as the best value furnace brand, with repair rates lower than expected for the price tier. Trane, Carrier, and Lennox still lead premium tiers but cost significantly more.
Climate-Specific Recommendations
Cold climate homes (zones 5-7 with sustained sub-freezing weather) should prioritize 95%+ AFUE with two-stage or modulating operation. The higher upfront cost recovers through fuel savings within 5-7 years, and the steady low-fire operation handles winter heating loads more comfortably.
Mild climate homes (zones 3-4 with light winter heating needs) can save money with 80% to 92% AFUE single-stage units. Heating costs are lower overall, so the fuel savings from condensing efficiency take longer to recover. A basic Goodman GR9T80 or GR9S92 handles these climates efficiently.
Hot-and-humid southern climates with minimal winter heating rarely justify high-efficiency condensing furnaces. A basic single-stage 80% AFUE unit suffices for the handful of cold nights each year. Spending the premium on better insulation or sealing usually returns more comfort than a high-end furnace.
2028 DOE Regulation Impact
The Department of Energy’s new efficiency standard requires 95% AFUE minimum for residential gas furnaces sold in the U.S. starting in 2028. Today, 80% AFUE units remain legal, but their resale value will likely drop as the deadline approaches.
For homeowners planning to keep their furnace past 2030, buying a condensing 95%+ unit today future-proofs against regulatory phase-outs of 80% equipment. Existing 80% AFUE installations remain legal to operate, but replacement parts availability may narrow over time.

Frequently Asked Questions
Which gas furnace brand did Consumer Reports rank as the best?
Consumer Reports ranked AirEase, Trane, and Payne as the most reliable gas furnace brands based on their 34,591-member reliability survey covering more than 20 brands. Trane and AirEase stood out for predicted reliability and owner satisfaction. Goodman and Amana, while positioned at lower price points, also ranked well in the same survey for their value tier.
What is the average cost of a new gas furnace?
A new gas furnace unit alone typically runs in the low-to-mid thousands depending on BTU size and efficiency, with professional installation adding two to ten times the equipment cost depending on ductwork, venting, and regional labor rates. A complete mid-efficiency Goodman installation for a typical home lands in the mid-thousands total. High-efficiency 96% AFUE condensing units with full installation, new venting, and a thermostat upgrade push total project costs into the high four-figures to low five-figures range.
Should I buy an 80 or 95 efficiency furnace?
Buy 95%+ AFUE if you live in a cold climate, heat with gas for more than 6 months per year, or plan to stay in your home more than 7 years. The fuel savings recover the higher upfront cost in that timeframe, and 95%+ units run quieter with more stable temperatures. Buy 80% AFUE only if you live in a mild climate, plan to move soon, or have venting constraints that make condensing furnace installation impractical.
What are the top three gas furnaces?
The top three gas furnace picks from our 2026 testing are the Goodman GM9S96 (96.1% AFUE with nine-speed ECM and lifetime heat exchanger warranty), the Goodman GR9T96 (96% AFUE two-stage with ENERGY STAR certification), and the Goodman GR9S92 (92% AFUE at a budget price with 10-year parts warranty). For premium tiers, Trane, Carrier, and Lennox remain the highest-rated brands but cost significantly more than Goodman equivalents.
Which brand of gas furnace is the most reliable?
Trane, Carrier, and Lennox consistently rank at the top of reliability surveys across HVAC industry data, with predicted reliability scores 15-25% above mid-tier brands. Among value brands, Goodman and Amana score surprisingly well, often matching premium brands in owner satisfaction surveys. Brands consistently flagged for reliability concerns include York, Luxaire, Gibson, Broan, Frigidaire, and Maytag.
Final Verdict: Best Gas Furnaces for Home
After three months of testing and research, the Goodman GM9S96 stands out as the best gas furnace for home use in 2026. Its 96.1% AFUE efficiency, nine-speed ECM blower, included thermostat, and lifetime heat exchanger warranty deliver premium-tier performance at a mid-tier price. For budget shoppers, the Goodman GR9S92 hits the 92% AFUE mark without crossing into premium pricing, and the Goodman GR9T96 delivers two-stage comfort that pays back the upfront difference in cold-climate homes.
Before you finalize a purchase, get three quotes from licensed HVAC contractors, verify authorized Goodman dealer status to protect your warranty, and confirm the right BTU size through a Manual J load calculation.
