Best Gas Furnace 2026: Top Picks for Your Home

Picking the best gas furnace for 2026 means you have to look at a lot of models, and each one has its own efficiency level and its own set of features. This guide breaks down the top gas furnace options on the U.S. market right now, explains what separates a good pick from a great one, and points out situations where a ductless heat pump may actually serve you better.

What Is the Best Gas Furnace in 2026? (Quick Answer)

There are two series that sit at the top of the pack for most homeowners: the Lennox SLP99V (up to 99% AFUE) and the Carrier Infinity 98 / 59MN7 (up to 98.5% AFUE). Both of these furnaces have a gas valve that can change the amount of heat in small steps, and they have a blower that can change speed, so the burner can go up or down to match how much heat the house needs. The result is warmth that stays even, operation that stays quiet and AFUE numbers that are much better than the numbers you get from older standard units that are only 80% AFUE. AFUE is a way to measure how well a furnace turns gas into heat you can use. A 99% rating means only 1% of the energy in the fuel is wasted.

"Best" is relative, though. A 99% AFUE furnace that can change its output in small steps is too much in a mild-winter city where the unit barely runs. Budget matters too: high efficiency models can cost more than $13,000 to get installed, while a solid 96% two stage unit may land under $6,000. And if the home has no ductwork at all, a ductless mini split heat pump (like the Zone Air systems we sell) often costs less to install and delivers heat plus cooling from a single system.

This guide is focused on ducted natural gas furnaces but also shows how they can compare with ductless heat pumps where that comparison matters for your heating decision. Rankings are based on the efficiency ratings of each unit, the features each one comes with, the terms of the warranty, and how typical U.S. homeowners use these systems as of fall 2026.

How We Chose the Best Gas Furnaces

Key Evaluation Criteria

Efficiency (AFUE). High-efficiency gas furnaces are in the 95% to 99% AFUE range. An AFUE rating of 95% or higher shows high energy efficiency and can qualify for most rebate programs. For cold climates, 95-99% is the target range. Milder regions often hit the cost-benefit sweet spot at 92-96%. Dual heat exchangers are common in high-efficiency models, capturing extra heat from exhaust gases that an 80% unit would vent outdoors. A high-efficiency furnace can turn up to 98% of fuel into usable heat.

Comfort and performance. Models with two stage heating can save energy and improve comfort by running at a lower output most of the time and going to full capacity only when needed. Furnaces that can change their heat output in small steps go further. Both of these approaches can reduce temperature changes compared to single-stage burners that cycle between full blast and off. Variable speed blowers can operate quietly and improve air filtration by moving air at lower, more steady speeds. Blower motor type has an impact on noise levels and electricity consumption: ECM motors use less electricity than older PSC motors. You can keep noise levels low with variable speed blowers and insulated blower sections. Communicating systems can optimize efficiency by coordinating furnace and thermostat, letting the control board and thermostat share data for tighter comfort control.

Reliability and warranty. Warranty coverage usually includes a lifetime warranty on heat exchangers in top-tier lines, with parts coverage around 10 years when registered within 30-90 days. Proper installation and regular maintenance matter more than brand logo for long term reliability. A poorly installed premium furnace will perform worse than a well-installed mid-tier one.

Total cost of ownership. New furnace installation costs between $2,000 and $10,000 depending on the unit, labor and configuration. Higher efficiency ratings mean higher upfront costs. Installation complexity affects total furnace costs. Condensing units need PVC venting, condensate drains and sometimes you need to upgrade the gas line. Variable speed systems can save money on utility bills over time, and high-efficiency furnaces often qualify for utility rebates or tax credits. You can get financing for furnaces through personal loans and HVAC programs that many contractors offer.

Real-world availability. All of the models listed here are common offerings in the U.S. and come with strong dealer networks. We focused on configurations that are common in homes from 1,200 to 3,000 sq ft.

Best Gas Furnaces for 2026

1. Lennox SLP99V. Best Overall High-Efficiency Furnace

The Lennox SLP99V is the furnace that sets the standard for how efficient a residential gas furnace can be. Lennox's SLP99V model reaches a 99% AFUE rating with a variable-capacity gas valve that changes heating output in small steps, paired with a variable speed ECM blower for premium performance in cold climates.

Why It Stands Out

Lennox furnaces can reach up to 99% AFUE ratings, which is the highest AFUE rating you can get right now from a major brand. The technology that changes heating output based on demand means the unit delivers just enough heat to hold the setpoint without going past it. You can get quiet operation with insulated blower components. Lennox's SilentComfort design covers the cabinet and the blower section so that sound levels stay low.

Best For

  • You if you live in colder climates (Midwest, Northeast, northern Rockies) and you have high annual heating loads

  • Buyers who are planning to stay 10-15+ years and want long term savings on gas

  • Those who want quiet, consistent comfort and are okay with a premium price tag

Key Strengths

  • There is up to 99% AFUE, the highest gas furnace efficiency currently on the market

  • Variable-capacity gas valve that steps output up and down so you get steady, dependable heating

  • Variable speed ECM blower that improves airflow, air filtration and humidity control when you pair it with an air conditioner or heat pump that works with it

  • ENERGY STAR certified. Eligible for many high-efficiency rebates

Possible Limitations

  • Higher initial cost compared to 95-97% AFUE two stage models. The gains from improved efficiency get smaller in mild climates

  • You need a strong Lennox authorized dealer for service because of more complex electronics

  • Lennox gives you a 5-year parts-only warranty on most models (the heat exchanger warranty is longer. Registration and dealer requirements apply)

2. Carrier Infinity 98 (59MN7). Best Smart Comfort

The Carrier Infinity 98 delivers up to 98.5% AFUE through a fully adjustable gas valve and variable speed blower, with Carrier's Infinity control system for advanced diagnostics and zoning.

Why It Stands Out

Carrier's Infinity series furnaces can reach up to 98.5% AFUE. The furnace that can change its output in fine steps keeps temperature swings tight and blower noise low. Smart thermostat integration, zoning compatibility and diagnostic data through the Infinity control set this carrier furnace apart from simpler systems.

Best For

  • So who is this for? You if you want app-based comfort control, zoning and system data

  • Houses with varying room-to-room loads where adjusting the heat output and zoning can matter

  • You if you already have Carrier and you are upgrading from older 80% or 90% units

Key Strengths

  • There is strong efficiency at 98.5% AFUE for energy savings in cold regions

  • Fully adjustable gas valve and variable speed blower for smooth, quiet variable speed operation

  • Carrier furnaces usually have a 10-year parts limited warranty

  • ENERGY STAR certified with a broad national dealer network

Possible Limitations

  • Premium equipment and controls that only work with Carrier push installation costs higher

  • Best performance needs compatible Infinity components. Mixing brands limits advanced features

  • There is more furnace than needed in small homes with mild winters

3. Bryant Evolution 98 Variable-Speed Furnace. Best Carrier-Family Alternative

Bryant and Carrier share a parent company and core engineering. Bryant's Evolution 98 Gas Furnace offers up to 98.5% AFUE with a gas valve that can change its output in small steps and a variable speed blower, often at a different price point depending on local dealers.

Why It Stands Out

Bryant's Evolution series furnaces can also reach up to 98.5% AFUE. The unit combines top-tier efficiency with advanced features like continuous low-speed circulation so you get consistent comfort between heating cycles. This bryant furnace is a strong pick if you prefer the Carrier platform but find better local pricing or service through Bryant's dealer network.

Best For

  • You if you like the Carrier/Bryant platform but get a better deal through a local Bryant dealer

  • Retrofits in existing ducted homes where quieter, more even heating is the goal

  • Buyers who want a premium furnace without going after the absolute highest AFUE number

Key Strengths

  • AFUE in the upper 98% range with modulating gas valve for balanced performance

  • Variable speed ECM blower that works with high-end AC or heat pump coils

  • Bryant offers a lifetime limited warranty on heat exchangers when you get it properly registered and installed by an authorized dealer

  • Broad U.S. availability and service support

Possible Limitations

  • You need careful setup and commissioning for full comfort benefits

  • Mid-tier Bryant Preferred models may offer excellent value in mild areas, though it is still priced as a premium system

  • You need the Evolution control system for the full feature set

4. Ruud U98V / U98MV. Best Value High Efficiency

Ruud's 98% AFUE models balance strong efficiency with competitive pricing and solid warranties, making them a practical pick for budget conscious homeowners who still want high AFUE performance.

Why It Stands Out

The Ruud U98V line hits 98% AFUE with two stage or operation that can change its output in small steps depending on the sub-series, at lower price points than some premium brands. The design is simple and easy to service, which is something you and contractors both like.

Best For

  • Homeowners who want 95%+ AFUE without luxury pricing

  • Regions where Ruud/Rheem dealers are strong and parts are easy to find

  • Buyers replacing older 80% units who want an efficiency jump

Key Strengths

  • 98% AFUE across multiple capacity points for typical homes

  • ENERGY STAR certified and eligible for many 2026 utility rebates

  • You can get good heat exchanger and parts warranty terms when you register it

  • Shared technology platform between Ruud and Rheem for broad parts availability

Possible Limitations

  • Fewer advanced technology extras than top Lennox or Carrier models

  • Feature set varies by dealer configuration. Review quotes carefully

  • You will want to research installer reviews, not just brand reputation, because local dealer quality can vary

5. Goodman/Amana. Best for Budget and Warranty

Goodman and Amana (brands from the same company) focus on price-to-performance. Amana's AMVM97 furnace reaches up to 98% AFUE ratings, and both brands offer multiple 95-98% AFUE options at lower cost than many premium furnace brands.

Why It Stands Out

Amana offers a 10-year unit replacement limited warranty on pick models, a coverage level few competitors match. Goodman units like the GR9S96 series provide ENERGY STAR-certified 96%+ AFUE at accessible pricing. These brands deliver reliable heating without the extra cost of luxury controls.

Best For

  • Budget conscious homeowners who need dependable heating at the lowest realistic installed cost

  • Owners of rental properties where upfront budget matters but you still want a strong warranty

  • Homes in moderate climates where run time is lower and peak-end premium features matter less

Key Strengths

  • Competitive AFUE ratings (96-98%) across a range of capacities

  • Amana offers a 10-year unit replacement warranty on pick models. Do strong heat exchanger warranties appeal to long-term owners?

  • Wide distribution and part availability in most U.S. markets

  • This is a good match for simple, non-zoned, single-thermostat systems

Possible Limitations

  • Fit, finish, noise levels and ultra-advanced features may lag the best furnace brand options from Lennox or Carrier

  • Lower price can attract less meticulous contractors. Installer quality is critical

  • Brand image may matter for resale in certain markets

6. American Standard / Trane Two-Stage 95-97% Furnaces. Best for Rugged Durability

American Standard and Trane share engineering and manufacturing. These are tough furnace brands known for heavy-duty heat exchanger construction and long service life.

Why It Stands Out

Trane's 96 gas furnace has an AFUE rating of 97.3%, and American Standard's Platinum 95 series matches it. Two stage heating and variable speed blowers come standard in many mid- to high-tier models. Trane furnaces have a peak AFUE rating of 97.3%, with a reputation for reliability in tough climates.

Best For

  • Homeowners in cold regions who want long term reliability more than going after 98-99% AFUE

  • Buyers who are planning to keep the new system running for 15-20 years

  • Situations where tough construction and a strong service network are priorities

Key Strengths

  • 95-97% AFUE two stage models that hit an efficiency sweet spot for many climates

  • Robust build quality and strong brand reputation for longevity

  • Variable speed blower options that pair well with high-efficiency central cooling or heat pumps

  • Trane provides a 10-year standard parts limited warranty. Solid warranty programs overall

Possible Limitations

  • Installed price can approach premium area with variable speed options

  • There are fewer ultra-high-AFUE (98-99%) SKUs than some competitors

  • Performance still depends on the installing contractor's design and setup

How to Choose a Gas Furnace

Choose Based on Climate and Heating Load

Cold climates (Upper Midwest, New England, interior mountain states) favor high-AFUE, two stage or furnaces that can change their output in small steps. Running 3,000+ heating hours per year, the fuel savings from a 98-99% unit add up. In milder climates (Pacific Coast, much of the South), a 95-96% AFUE two stage furnace often hits the sweet spot. In regions with mild winters and cheap electricity, a high-efficiency heat pump or ductless system may beat a new gas furnace on both cost and carbon. A Manual J load calculation ensures proper furnace sizing for your home's actual heating needs.

Choose Based on Ductwork and Equipment

If your ducts are solid and well-sealed, focus on furnace AFUE, staging and blower type. Leaky or undersized ducts can waste 10-30% of system output. Even the best gas furnace will perform worse through bad ductwork. Homes without ducts are often better served by ductless mini split heat pumps, such as Zone Air systems, rather than adding a completely new ducted system.

Choose Based on Fuel and Operating Costs

Compare local natural gas and electricity prices to figure out whether a high-efficiency gas furnace or a ductless heat pump is more economical over 10-15 years. ENERGY STAR has found that certified ductless heat pumps use up to 60% less energy than baseboard electric heat, and that about half of a typical $1,900 U.S. annual energy bill goes to heating and cooling. Use simple payback math: divide the extra cost of a 98-99% AFUE unit by annual fuel savings versus a 95% unit. If payback exceeds 10 years, the mid-tier furnace may be the smarter buy. Many states offer rebates tied to AFUE thresholds. North Carolina's Enbridge Gas, for example, pays $400 for furnaces at 97%+ AFUE.

Choose Based on Budget and Time Horizon

Short-term ownership (under 5 years) favors mid-tier 95-96% models where payback on the additional cost of a 99% unit may not happen before you sell. Long-term ownership (10-20 years) can make sense for 98-99% AFUE because of cumulative energy savings. Many contractors offer financing options, and stacking utility rebates with manufacturer promotions can lower the effective initial cost. Do not undersize the budget just to get the cheapest install if it means sacrificing correct sizing, proper installation or repair costs down the road.

Is a Gas Furnace Really the Best Choice, or Should You Consider Ductless?

We specialize in DIY-friendly ductless heat pump systems, so we want to be upfront: gas furnaces are the right tool for many homes, but not all of them.

When a Gas Furnace Makes Sense

  • Existing ducted homes with reliable natural gas service and harsh winters where you want combustion heat

  • Replacing an aging 80% furnace with a 95-98% unit when the ducts are in good condition

  • You if you prefer working with local HVAC contractors for a turnkey ducted solution

When Ductless May Be Better

  • Homes without ducts, additions, finished basements, garages or bonus rooms where running new ductwork is expensive or not practical

  • Regions with moderate winters where a ductless heat pump can handle heating loads efficiently most or all of the year

  • Zone Air DIY ductless systems ship with factory-sealed, pre-charged quick-connect line sets. No vacuum pump, gauges or EPA 608 card are needed. Many homeowners install them with a handyman plus an electrician for the dedicated circuit. Zone Air 9K and 12K systems use a 3/8 in gas / 1/4 in liquid line set, while the 18K steps up to 1/2 in / 1/4 in, which is why we sell separate 25 ft line set kits for each size range.

Gas Furnaces vs. Ductless Heat Pumps

Even a 98-99% AFUE gas furnace still burns fuel. A ductless heat pump moves heat rather than generating it, often reaching a coefficient of performance above 3 under favorable conditions. For every 1 unit of electricity that is consumed, you get 3 or more units of heat delivered. ENERGY STAR data show certified ductless heat pumps can avoid over 4,500 lb of greenhouse gas emissions over their life. In extremely cold weather, a hybrid system (gas furnace plus heat pump) or a cold-climate rated heat pump may be worth looking into with a pro.

Which Furnace Is Best for You?

You can use this as a quick decision help sheet:

  • Lennox SLP99V if you want the quietest, most efficient gas heating available and live in a cold climate where the furnace runs heavily every winter.

  • Carrier Infinity 98 if you care about smart controls, zoning and ultra-smooth comfort with a fully modulating system.

  • Bryant Evolution 98 if you like the Carrier/Bryant platform and your local Bryant dealer offers better pricing or service.

  • Ruud U98V/U98MV if you want 98% AFUE performance at a more moderate price, especially with strong local Ruud or Rheem dealers.

  • Goodman or Amana high-efficiency model if budget and warranty length are top priorities and you can find a reputable installer.

  • American Standard or Trane 95-97% two stage furnace if you value rugged construction and plan to keep the system running for 15-20 years.

  • Ductless mini split heat pump (like Zone Air) instead of a gas furnace if you lack ductwork, have moderate winters or prefer a DIY-friendly, all-electric option with both heating and cooling in one unit.

Final Thoughts

The best gas furnace in 2026 is the one matched to your climate, ducts, fuel prices, heating needs and budget. The highest AFUE number on paper does not automatically mean the right furnace for your home. Getting the size right through a Manual J calculation, having solid ductwork and getting a high-quality proper installation matter as much as the brand name on the cabinet.
