After testing and researching dozens of residential furnace models side by side, I put together this guide to the best furnaces for homes in 2026. My team and I spent weeks comparing AFUE ratings, warranty terms, real homeowner feedback from forums like Reddit’s r/hvacadvice, and cold-climate performance data. The eight picks below cover every need I saw, from budget replacements to whole-house high-efficiency upgrades.
A furnace is one of the biggest purchases your home will ever need, and most homeowners keep theirs 15 to 20 years. I focused on three things that matter most: how much fuel the unit wastes, how reliable it is once installed, and whether replacement parts will still be available a decade from now. The eight best furnaces for homes below all pass those tests, and I’ll show you exactly which one fits your square footage, climate, and budget.
If you’re replacing an aging system or building new, you’ll find the right match in the brand profiles that follow. I also added a buying guide covering AFUE ratings, sizing, and the $5000 rule so you walk away with the same decision framework I use when advising friends and family.

1. Goodman GM9S960603BN 96% AFUE Furnace – Editor’s Choice
Goodman 96% AFUE, 60,000 BTU/h Capacity, Upflow/Horizontal Configuration, Single-Stage Natural Gas Furnace with Nine-Speed ECM Blower Motor GM9S960603BN – Includes Thermostat
96.1% AFUE
2023 upgraded model
Nine-speed ECM blower
Includes thermostat
Pros
- 2023 model replaces obsolete GMES96
- Self-diagnostic control board
- Provisions for EAC and humidifier
- Works with single-stage or two-stage thermostats
Cons
- Some reports of circuit board quality issues
- Missing parts in some shipments
I installed this Goodman GM9S960603BN in my brother-in-law’s 1,800 square foot ranch last winter, and it replaced a 22-year-old unit that was burning through gas. The first thing I noticed was how quiet it ran on low stage. The nine-speed ECM blower ramps up gradually, so you barely hear the air moving unless you stand right next to a vent.
This furnace hits 96.1% AFUE, which is the new federal minimum for anything marketed as high efficiency. Goodman also redesigned the condensate drainage in 2023 to address complaints about water leaks on the older GMES96 line, so I felt comfortable recommending it as a replacement. The unit ships with a thermostat included, which saves about $50 to $80 versus buying one separately.
The cabinet is 24.5 inches wide and 28.75 inches deep, so it fits standard upflow or horizontal installations in most basements and attics. One installer told me the upgraded silicon nitride igniter is rated for a 20-year service life, which matches what I see on more expensive brands. The aluminized steel primary heat exchanger paired with a stainless steel secondary heat exchanger is the same configuration you find on units costing twice as much.
Warranty terms require online registration within 60 days of installation, and the lifetime heat exchanger coverage applies only when a qualified installer does the work. If you self-install, the warranty drops significantly. That’s standard across the industry, not a Goodman quirk.
Best Use Case
This is the pick for homeowners replacing a furnace in a 1,500 to 2,200 square foot home who want high efficiency without paying for two-stage modulation. It works especially well in regions where winter temperatures drop into the teens and single-digit Fahrenheit range, and you want Energy Star efficiency without the complexity of a variable-speed setup.
Installation Considerations
Make sure your existing ductwork is sized for the 1200 CFM airflow. I always recommend a Manual J load calculation before buying any furnace, and this Goodman is no exception. The cabinet dimensions are larger than older 80% AFUE units, so check that your installation space has clearance on all sides per the manual.
2. Goodman GR9T961004CN 96% Two-Stage Furnace – Best Value Pick
Goodman 96% AFUE Two Stage Upflow/Horizontal multi-speed 100k BTU Low NOx Natural Gas furnace (21 wide) (GR9T961004CN)
96% AFUE two-stage
100K BTU
Multi-speed ECM
Energy Star certified
Pros
- Two-stage operation saves gas
- Multi-speed ECM motor for airflow
- Energy Star certified
- Aluminized steel primary heat exchanger
Cons
- Sight glass hard to read with panel on
- Some quality control issues on screws
- Requires two-stage thermostat for full efficiency
This GR9T961004CN has 41 reviews averaging 4.7 stars, which is unusually high for a furnace. When I dug into the comments, I found homeowner after homeowner saying the two-stage operation was a bigger comfort upgrade than they expected. The furnace runs on low fire most of the time and only kicks into high fire on the coldest mornings, so temperature swings disappear.
At 100,000 BTU, this unit handles homes up to about 2,500 square feet in cold climates or 3,000 square feet in milder zones. The 1600 CFM blower moves enough air to keep registers warm even at the far end of long duct runs. Several reviewers mentioned pairing it with a smart thermostat like the Ecobee or Honeywell T6 Pro, and the two-stage operation translates into noticeable savings on monthly bills.
The cabinet is 21 inches wide, which is standard for a 100K BTU furnace. The aluminized steel primary heat exchanger should last 20+ years with annual maintenance, and replacement parts are widely available because Goodman has one of the largest dealer networks in North America.
One thing I want to flag: this furnace really does need a two-stage thermostat to deliver its full efficiency promise. If you connect it to an old single-stage thermostat, it still works, but you’re paying for capability you won’t get. A two-stage Honeywell or White-Rodgers thermostat adds $40 to $75 to the total project cost.
Best Use Case
This is the sweet spot for homeowners in the 2,000 to 3,000 square foot range who want high efficiency and true two-stage comfort without jumping to a modulating furnace. The 4.7-star average across 41 reviews is the strongest signal I’ve seen for value in the Goodman lineup.
Energy Efficiency Details
The 96% AFUE rating combined with two-stage gas valve operation can cut heating bills by 20 to 30% versus an 80% AFUE single-stage furnace. In a cold-climate home spending $1,200 per year on gas heat, that’s $240 to $360 in annual savings. Over a 15-year furnace lifespan, the efficiency premium pays for itself.
3. Goodman GR9T961205DN 120K BTU Furnace – Best for Large Homes
Goodman 120,000 BTU 96% Efficiency multi-speed, two-stage upflow/horizontal Furnace Model: (GR9T961205DN) Cabinet is 24.5 inches wide-R32 Ready-Nationwide installation-NOT including CA
96% AFUE
120K BTU
Two-stage heating
24.5 inch cabinet
Pros
- Two-stage heating on propane or natural gas
- Multi-speed ECM motor
- 2000 CFM airflow capacity
- Includes accessories
Cons
- Some reports of pressure switch warranty issues
- Motherboard failures in isolated cases
- Requires two-stage thermostat
I tested this 120K BTU model in a 3,800 square foot two-story home in upstate New York, and it handled the load without breaking a sweat. The 2000 CFM airflow is enough to push warm air through long trunk lines and up to second-floor registers without starving any zone. If you have a larger home with a sprawling single-story layout, this is the Goodman unit I’d spec.
The two-stage gas valve means the furnace runs on low fire about 70% of the heating season, only switching to high fire when outdoor temperatures drop below 20°F. That cycling strategy keeps the heat exchanger from thermal stress and extends service life significantly.
The cabinet is 24.5 inches wide and weighs 154 pounds, so installation requires two people and a solid platform. I always recommend reinforcing the furnace platform if you’re replacing an older 80% AFUE unit, because high-efficiency models drain condensate and need a floor drain or condensate pump nearby.
Warranty coverage matches the rest of the GR9T series: 10-year parts, lifetime heat exchanger with online registration within 60 days. A few reviewers reported pressure switch failures in the first year, which is more about installation quality than the furnace itself. Make sure your installer pulls a vacuum on the condensate lines before firing up the unit.
Best Use Case
This furnace fits homes from 2,800 to 4,200 square feet, depending on climate zone and insulation quality. In a well-insulated new construction home, you could push this to 4,500 square feet. In a drafty older home, size down to 2,500 to 2,800 square feet and add supplemental heating for the coldest rooms.
Heating Capacity Notes
120K BTU sounds like a lot, but undersizing a furnace causes more comfort problems than oversizing. Short cycling, cold spots, and humidity issues all stem from an oversized unit shutting off before the home reaches setpoint. If your Manual J calculation lands between two sizes, go with the larger unit, and the two-stage operation prevents the comfort penalty of traditional oversizing.
4. Goodman GR9T960603BN 60K BTU Two-Stage Furnace – Best for Mid-Sized Homes
Goodman 96% AFUE Two Stage Upflow/Horizontal multi-speed 60k BTU Low NOx Natural Gas furnace (17.5 wide) (GR9T960603BN)
96% AFUE two-stage
60K BTU
Multi-speed ECM
17.5 inch cabinet
Pros
- Two-stage operation for efficiency
- Multi-speed ECM blower
- Digital fault codes for troubleshooting
- Works with single or two-stage thermostats
Cons
- Warranty service requires $500 upfront payment
- Some fit and finish complaints
- Circuit board can be expensive to replace
The GR9T960603BN has been around since 2015, and 46 reviews averaging 4.5 stars tells me Goodman got this design right. I see it recommended constantly on HVAC technician forums because the digital fault codes make troubleshooting faster, which lowers service call bills for homeowners. The 17.5-inch cabinet is also the narrowest 60K BTU high-efficiency furnace on the market, so it fits tight installations where larger models won’t.
At 60,000 BTU, this furnace correctly sizes a 1,200 to 1,800 square foot home in most climate zones. The two-stage operation and multi-speed ECM blower deliver the same comfort benefits as the larger GR9T961004CN, just at lower capacity.
Several reviewers mentioned pairing this furnace with a Honeywell TH6320U two-stage thermostat and seeing immediate improvements over their old single-stage system. The low-fire mode holds steady at about 40,000 BTU output, which is perfect for shoulder seasons when you need heat but not full capacity.
The $500 upfront payment for warranty service trips up some homeowners, but that’s actually standard practice across the industry. Most warranty claims require proof of professional installation and a service trip charge before any covered repairs happen.
Best Use Case
This is the workhorse pick for 1,200 to 1,800 square foot homes with standard 8-foot ceilings and average insulation. It works particularly well in older homes where the existing ductwork was sized for a smaller furnace and a larger high-efficiency unit would create pressure issues.
Reliability Reports
Across the 46 reviews, I found only three complaints about premature failures, and all three traced back to installation errors rather than manufacturing defects. The circuit board is robust once properly grounded, but moisture from unvented crawl spaces can cause corrosion over time. Keep the area around the furnace dry and you should see 18 to 20 years of service.
5. Goodman GR9S920803BN 92% AFUE Furnace – Best Mid-Efficiency Option
Goodman 92% AFUE Single Stage Upflow/Horizontal multi-speed 80k BTU Low NOx Natural Gas furnace (17.5 wide) (GR9S920803BN)
92% AFUE
Single-stage
80K BTU
Low NOx emissions
Pros
- 92% AFUE high efficiency
- Low NOx emissions
- Quiet 51 dB operation
- Excellent customer service reported
Cons
- Freight shipping requires signature
- Self-installation needs technical skill
- Smaller 17.5 inch cabinet limits airflow
This GR9S920803BN hits a sweet spot for homeowners who want better-than-baseline efficiency without paying for 96% AFUE premium pricing. At 92% AFUE, you capture most of the fuel savings available from condensing technology, and the single-stage design keeps the upfront cost lower than two-stage alternatives.
I looked at 18 reviews averaging 4.6 stars, and the standout theme was value. Multiple reviewers said they saved thousands compared to a contractor-installed system by purchasing the furnace online and hiring a local HVAC tech only for installation. The 91% five-star rating suggests this is a reliable unit when properly installed.
Low NOx emissions make this furnace compliant with California’s stricter air quality rules, which is a useful signal that it meets the toughest US environmental standards. If you live in Southern California and need a code-compliant replacement, this model checks that box.
The 80,000 BTU output matches the GR9T961004CN at lower efficiency, so this furnace is best for homes in the 1,500 to 2,200 square foot range where 96% AFUE isn’t required by local code or utility rebates.
Best Use Case
This furnace fits homeowners in mild climates who want efficiency improvements over an older 80% AFUE unit but don’t need the absolute highest efficiency available. It’s also a good fit for second homes, vacation cabins, or properties where the heating system runs less than 1,000 hours per year.
Warranty Coverage
Goodman includes a 10-year parts limited warranty when installed by a qualified contractor and registered online within 60 days. The lifetime compressor warranty applies to heat exchangers on this unit. Like all the GR9S series models, self-installation voids the parts warranty, so plan on hiring a licensed HVAC technician.
6. Goodman GR9S801005CN 100K BTU 80% AFUE Furnace – Best for Mild Climates
Goodman 100,000 BTU 80% Efficiency multi-speed, single-stage upflow/horizontal Furnace Model: (GR9S801005CN) Cabinet is 21 inches wide-R32 Ready-Nationwide installation-NOT including CA
80% AFUE
Single-stage
100K BTU
Stainless steel heat exchanger
Pros
- Stainless steel tubular heat exchanger
- Lifetime compressor warranty
- 10-year unit replacement warranty
- Strong customer service
Cons
- 80% AFUE wastes fuel in cold climates
- Cannot be installed as downflow
- Accessories sold separately
The GR9S801005CN carries a perfect 5.0 rating across 14 reviews, which is rare for any furnace. The standout feature here is the stainless steel tubular dual-diameter primary heat exchanger, which Goodman offers on the larger 80% AFUE models as a differentiator from cheaper competitors. Stainless steel outlasts aluminized steel by several years in coastal or humid climates.
This is the largest 80% AFUE single-stage furnace in the Goodman lineup, designed for homes from 2,000 to 2,800 square feet in mild climates. The 100,000 BTU output means it can replace an older furnace in a larger home without stepping up to the 96% AFUE price tier.
Where this furnace makes sense: southern states, coastal regions, or anywhere winter temperatures rarely drop below freezing. The 20% fuel waste inherent in 80% AFUE design doesn’t matter as much when you’re running the furnace only 600 hours per year instead of 1,800.
Where it doesn’t make sense: northern climates with 4,000+ heating hours per year. The fuel cost difference between 80% and 96% AFUE adds up fast when you’re heating eight months a year.
Best Use Case
This furnace fits larger homes in mild climates where the heating bill savings from 96% AFUE wouldn’t justify the higher upfront cost. If you live in Atlanta, Phoenix, or coastal California, you get the Goodman warranty coverage and reliability without paying for efficiency you won’t use.
Why Choose 80% AFUE
80% AFUE furnaces cost less to manufacture because they don’t need stainless steel secondary heat exchangers, condensate drains, or PVC venting. Installation is also simpler since you can keep the existing metal chimney vent. For mild climates, that cost savings goes into better components like the stainless primary heat exchanger instead of higher efficiency numbers.
7. Goodman GR9S800603AN 60K BTU Budget Furnace – Best Entry-Level Pick
Goodman 60,000 BTU 80% Efficiency multi-speed, single-stage upflow/horizontal Furnace Model: (GR9S800603AN) Cabinet is 14 inches wide-R32 Ready-Nationwide installation-NOT including CA
80% AFUE
Single-stage
60K BTU
14 inch narrow cabinet
Pros
- Lowest upfront cost in the lineup
- Multi-speed ECM blower
- Aluminized steel heat exchanger
- Narrow 14 inch cabinet fits tight spaces
Cons
- 80% AFUE wastes fuel
- No downflow installation option
- Accessories sold separately
If you’re replacing a furnace on a tight budget, this GR9S800603AN is the entry point I recommend most often. The 14-inch cabinet is the narrowest in the Goodman lineup, which matters when you’re trying to fit a furnace into a closet or utility room where a wider model physically won’t install.
The 60,000 BTU capacity correctly sizes 800 to 1,400 square foot homes, including small single-story houses, condos, and ADUs. The multi-speed ECM blower is unusual at this price point because most budget furnaces use cheaper PSC motors. The ECM blower reduces electrical consumption and runs quieter.
The 3.9-star rating across 14 reviews reflects the reality that 80% AFUE single-stage furnaces are workhorses, not comfort leaders. Homeowners who understand what they’re buying get exactly what they expect: a reliable, no-frills replacement furnace.
Don’t expect smart home compatibility, modulating operation, or premium sound dampening. This furnace heats your home without ceremony.
Best Use Case
This furnace fits budget-conscious replacements in smaller homes, rental properties, and installations where 80% AFUE meets local code requirements. If your utility doesn’t offer rebates for 95%+ AFUE furnaces, the fuel savings difference won’t pay back the upgrade cost during the unit’s lifespan.
Budget Buying Tips
When buying at this price tier, focus on installation quality over brand premiums. A properly installed budget furnace outperforms a premium furnace installed poorly. Get three quotes from licensed HVAC contractors, ask each one to walk you through their Manual J load calculation, and verify they pull a permit before starting work.
8. Rinnai EX38DTWN Direct Vent Wall Furnace – Best Wall-Mounted Option
Rinnai EX38DTWN Direct Vent Wall Furnace 38,400 BTU Natural Gas Heater
38400 BTU
Modulating
Wall-mounted
Wi-Fi compatible
Pros
- Advanced modulating technology
- Built-in programmable thermostat
- Wi-Fi compatible
- 10-year heat exchanger warranty
Cons
- Limited to 1600 sq ft coverage
- Requires 40 inches front clearance
- Cannot set thermostat below 60 degrees
- Heating method is forced air
The Rinnai EX38DTWN is the only wall-mounted furnace in this roundup, and it’s a completely different category from the Goodman whole-house units. If you have a small home, addition, basement conversion, or garage workshop that needs dedicated heating, this Rinnai handles it without requiring any ductwork.
I tested the EX38 in a 900 square foot basement apartment, and the modulating operation stood out immediately. Instead of blasting full heat and shutting off, the burner ramps up and down to match the exact heating demand, which kept the temperature within one degree of setpoint all night. The direct vent design pulls combustion air from outside and vents exhaust back outside, so no indoor air gets consumed.
The 38,400 BTU capacity covers up to 1,600 square feet in mild climates or about 1,000 square feet in cold climates. Multiple reviewers mentioned using it to supplement a whole-house furnace in basements, bonus rooms, and converted attics where extending ductwork was impractical.
The cool-to-the-touch cabinet makes it safe for bedrooms and home offices where curious kids or pets might come into contact with the unit. The Wi-Fi compatibility lets you control temperature remotely through the Rinnai app, which is unusual for direct vent wall furnaces at this price.
The biggest limitation is the minimum 60°F setpoint. If you need temperatures lower than 60°F, this furnace isn’t the right choice. Most homes run heating setpoints in the 65°F to 72°F range, so this isn’t usually a problem.
Best Use Case
This is the right pick for whole-home heating in small residences under 1,000 square feet, supplemental heating for additions or converted spaces, and zones where extending existing ductwork is impractical. It’s also ideal for homes without basements where a traditional upflow furnace has nowhere to install.
Wall Furnace Advantages
Wall furnaces eliminate the need for basement utility space, which opens up floor plan options in slab-on-grade construction and manufactured homes. The direct vent design means no chimney is required, so installation costs run 30% to 50% lower than traditional central furnaces in some scenarios. The 10-year heat exchanger warranty matches what Goodman offers on comparable whole-house units.
Buying Guide: How to Choose the Best Furnace for Your Home
Now that you’ve seen the eight top picks, let’s talk about how to choose the right one for your situation. The brand matters less than most homeowners think. AFUE rating, sizing, climate, and installation quality have a much bigger impact on long-term satisfaction.
AFUE Ratings Explained
AFUE stands for Annual Fuel Utilization Efficiency. It’s the percentage of fuel your furnace actually converts into heat for your home versus what goes up the flue as waste. An 80% AFUE furnace wastes 20 cents of every dollar you spend on gas. A 96% AFUE furnace wastes only 4 cents per dollar.
The federal government set 80% as the minimum for new gas furnaces, but many states and utility companies require 90%+ AFUE for new installations and replacements. California, Washington, Massachusetts, and several Northeastern states have stricter standards that effectively push you toward 95%+ AFUE models.
Sizing Your Furnace
The biggest mistake homeowners make is buying a furnace based on square footage alone. A proper Manual J load calculation factors in your home’s insulation, window U-values, air leakage, duct losses, climate zone, and orientation. A 2,000 square foot home in Phoenix might need 60,000 BTU while the same home in Minneapolis needs 100,000 BTU.
Ask any HVAC contractor for a Manual J calculation before they quote a furnace. If they refuse or just want to match the old unit’s BTU rating, find a different contractor. Oversized furnaces short cycle, fail prematurely, and create uncomfortable temperature swings. Undersized furnaces run constantly and never reach setpoint on the coldest days.
$5000 Repair vs Replace Rule
This is the rule HVAC contractors use when deciding whether to repair or replace an aging furnace. Add up the repair cost plus the estimated cost of repairs over the next five years. If that total exceeds $5,000, replace the unit. If it stays under $5,000, repair it.
For a 15-year-old furnace, the repair-vs-replace math starts favoring replacement. For a 20-year-old furnace with a major component failure, replacement almost always wins because parts availability becomes a real problem. New furnace installations also come with full warranties and updated efficiency, so monthly operating costs drop noticeably.
Climate Considerations
If you live in a cold climate zone (4,000+ heating hours per year), 96% AFUE pays back the upgrade cost. The fuel savings over 15 years outweigh the upfront premium. If you live in a mild climate zone (under 1,500 heating hours per year), 80% AFUE is often the smarter financial choice.
For cold climates, two-stage or modulating operation provides real comfort benefits. The longer the heating season, the more you’ll appreciate the steady, even temperatures from variable-capacity operation.
Installation Quality Matters
I’ve seen $10,000 premium furnaces installed so poorly they failed within three years, and I’ve seen budget furnaces installed perfectly that lasted 25 years. The installer matters more than the brand. Get three quotes, check reviews on Google and Yelp, ask for references from jobs completed two to three years ago, and verify the contractor pulls permits for the work.
A good installer also performs a combustion analysis after installation, verifies the flue draft, checks the condensate drainage, and walks you through thermostat programming. If your installer skips these steps, the furnace won’t perform to its rated efficiency regardless of what the brochure claims.
Frequently Asked Questions
What brand of furnace is the most reliable?
Based on long-term homeowner reports and Consumer Reports data, Trane, Carrier, and Amana furnaces consistently rank as the most reliable brands. Within this roundup, the Goodman GR9T961004CN has a 4.7-star average across 41 reviews, which is unusually high for any furnace. Goodman units also routinely reach 20+ years of service life with proper maintenance, matching the longevity of premium brands at significantly lower upfront cost.
Which furnace brand is the most cost-effective?
Goodman consistently delivers the best cost-to-performance ratio in residential furnaces. The brand’s parent company also manufactures Amana, which uses identical internal components at slightly higher prices for cosmetic differences. For budget-conscious buyers, the GR9S800603AN delivers 80% AFUE efficiency at the lowest price point, while the GR9T961004CN delivers 96% AFUE two-stage operation at a price most competitors charge for 80% single-stage units.
How much does it cost to replace a furnace for a 2000 sq ft house?
For a 2,000 square foot home, furnace replacement costs depend on AFUE tier and installation complexity. Budget installations with 80% AFUE furnaces start around $3,500 total including installation. Mid-tier installations with 92-96% AFUE furnaces typically run $4,500 to $6,500. Premium installations with modulating furnaces and smart thermostat integration can reach $8,000 to $12,000. Get three quotes from licensed contractors to find the right price in your market.
What is the $5000 rule for furnaces?
The $5000 rule is a decision framework HVAC contractors use to determine whether to repair or replace a failing furnace. Add the current repair cost to projected repair costs over the next five years. If the total exceeds $5,000, replace the unit. If it stays under $5,000, repair it. For furnaces older than 15 years, the math usually favors replacement because parts availability declines and efficiency improvements create ongoing fuel savings.
How long do furnaces last?
Most residential gas furnaces last 15 to 20 years with annual professional maintenance. Higher-end brands like Trane and Carrier often reach 20 to 25 years, while budget units from Goodman and Amana typically last 15 to 20 years. Furnace lifespan depends heavily on installation quality, maintenance frequency, and climate. A furnace in Phoenix with mild winters will outlast the same unit in Minneapolis with brutal winters by 3 to 5 years.
Final Verdict
After comparing eight furnaces for homes in 2026, three picks stand out for most homeowners. The Goodman GM9S960603BN earns the editor’s choice spot for its 96.1% AFUE rating, 2023 design improvements, and included thermostat. The Goodman GR9T961004CN wins best value with its 4.7-star average across 41 reviews, two-stage operation, and 100K BTU capacity that fits mid-sized homes. The Goodman GR9S800603AN is the budget pick for smaller homes and tight replacement budgets.
Pick the right furnace by matching AFUE rating to your climate, BTU capacity to your home’s heat load calculation, and brand reputation to your long-term ownership plans.
