Our Reviews of the Best Furnace Brands
Below are our top recommendations for home furnace brands. Our methodology favors companies with higher average efficiency ratings and lower starting costs. However, these factors don’t always align, so many of our top choices feature higher pricing. We suggest you investigate each provider in detail to determine which best matches your budget and heating needs.
Price Range: $3,000–$15,000
Warranty: 10-year parts-only limited, 20-year limited heat exchanger, 3-year labor limited
Peak AFUE: 98.5%
Pros and Cons
Pros
- Has high energy efficiency rates of up to 98.5% AFUE
- Includes a 10-year limited parts warranty for registered products
- Includes humidity control for many of its furnaces
Cons
- Requires a salesperson to visit your home for accurate cost information
- Is more expensive than other brands
Our Review and Insights
Carrier stands out for its energy efficiency technology. Its Infinity series furnaces achieve up to 98.5% AFUE ratings, which can save you money on heating bills. We’re also impressed by Carrier’s Greenspeed Intelligence technology, which allows its furnaces to operate at multiple stages rather than simple on/off cycling, providing more consistent heating and improved humidity control.
However, Carrier’s premium quality comes with premium pricing, typically running 10%–15% higher than comparable models from brands like Amana or York. While Carrier’s warranty coverage is solid at 10 years for parts and 20 years for heat exchangers, it’s not significantly better than what other top-tier manufacturers offer. Installation can also be more complex due to Carrier’s proprietary components, which means you’ll need to work with certified Carrier dealers, potentially limiting your contractor options. Despite these considerations, we believe Carrier’s superior build quality, exceptional energy efficiency, and proven reliability make it worth the investment.
Customer Reviews
Carrier is not accredited by the Better Business Bureau (BBB), and it’s currently not rated by BBB because the business is in the process of responding to previously closed complaints. Carrier has a star rating of 1.06 out of 5. Lower average customer ratings aren’t uncommon because most customers review a company when something goes wrong. We noticed that Carrier gets a review roughly once a month. Some customers praise the installers, though many customers express concerns with Carrier’s customer service and having to deal with corporate red tape and bureaucracy.
“We have been long-time Carrier customers and had been very satisfied[,] so after [a] hurricane we needed to replace 2 units … Paid for service, been without AC for several weeks at a time, multiple times. We have no issue with our installers, they come and have been very gracious to try and get us up and running. … We had bought fans, mobile AC units and lived in hot humid conditions for weeks at a time and now for months. … Finally, a full 6 months later Carrier replaced the entire outside unit. We however had to pay the installation, $1,780. We of course paid it immediately, our service people deserved to be paid, they did the work. … I finally reached out [by] certified mail to president and vp of the company. This escalated to the management response team who came back with the legal contract that protects them. Sometimes there is a difference between being legally protected and doing the right thing…” –Anne Marie D. via BBB in November 2024
“I purchased a Carrier Green speed only three years ago. I am already having issues with it. The unit was over $13,000. And in just three years I have already spent more than $500 on repairs. I have low confidence in the Carrier brand. There website doesn’t have extensive information to diagnose the various error codes. And, in contacting Carrier, they refer customers to external servicing agents—which is costly to the customer.” –Dario M. via BBB in June 2023
Price Range: $3,100–$10,000
Warranty: 5-year parts-only warranty (10 years for Dave Lennox Signature Collection), 20-year heat exchanger
Peak AFUE: 99%
Pros and Cons
Pros
- Has the highest AFUE rating on this list
- Features low sound ratings for its oil furnaces
- Is available at popular retailers such as the Home Depot
Cons
- Requires a salesperson to visit your home for accurate cost information
- Is more expensive than other brands
Our Review and Insights
Lennox has the highest possible AFUE rating on this list. Its Dave Lennox Signature Collection, particularly the SLP99V model, achieves an outstanding 99% AFUE rating, currently the highest efficiency rating available in residential furnaces. This exceptional performance comes from its variable-capacity technology, which precisely adjusts heat output in increments as small as 1%. The brand’s SilentComfort technology also makes its units among the quietest we’ve seen, operating at sound levels comparable to a normal conversation.
While Lennox’s technology and efficiency are impressive, its proprietary parts system typically costs 20%–30% more than standard replacement parts, and you’ll need to work with Lennox-certified technicians for repairs and maintenance. Additionally, while its warranty coverage (10-year limited parts, 20-year heat exchanger) matches industry standards, Lennox’s strict maintenance requirements for warranty validation are more demanding than those from most competitors. Despite these limitations, Lennox remains an excellent choice for homeowners who prioritize maximum energy efficiency and are willing to commit to regular maintenance.
Customer Reviews
Lennox has a BBB rating of 1.08 out of 5 stars, but it does hold accreditation and has an A+ score. Customers praise Lennox for its unit performance and general customer service. Issues arise when customers attempt to use their warranties, though. Customers mention difficulty communicating and a lack of resolution regarding Lennox’s warranty coverage.
“Super nice rep helped me today. So nice to chat about our problem with evap coil replacement with someone that I could understand and that was willing to look up my warranty. She went the extra mile.” –Paula F. via BBB in July 2023
“I got two Lennox systems, which were supposed to have 10 year warranties. One of the thermostats failed after 5 years and 10 months. I called Lennox and they said sorry, we can’t help you. The warranty on the thermostat is only 5 years. They said the 10 year period applies to the rest of the system. I asked if they would replace it anyway, since it is just out of warranty and I paid a lot of money (over $40,000) to get Lennox quality. They said no. ‘Sorry I don’t have better news for you’ was the precise language they used. This is not how a quality company responds to a problem.” –Dudley V. via BBB in October 2024
Bryant Furnace
Best for DurabilityPrice Range: $3,500– $6,000
Warranty: 10-year standard parts limited warranty, lifetime heat exchanger
Peak AFUE: 98.3%
Pros and Cons
Pros
- Produces sturdy furnaces with aluminized steel
- Offers packaged heating and cooling systems
- Includes a lifetime heat exchanger limited warranty
Cons
- Provides warranties that are less comprehensive than other brands
- Doesn’t offer premium or luxury models
Our Review and Insights
Bryant’s furnace lineup excels in delivering reliable performance at a cheaper price point than its parent company, Carrier. Bryant’s Evolution series furnaces achieve up to 98.3% AFUE ratings, falling slightly below Carrier’s top models but still ranking among the most efficient systems. Additionally, Bryant incorporates much of the same core technology as Carrier, such as its Perfect Heat technology for multistage operation, while costing 15%–20% less. We found Bryant’s temperature consistency and humidity control capabilities nearly matched those of premium Carrier models.
However, Bryant makes compromises to achieve these lower price points. While it uses many components similar to Carrier, Bryant’s warranty coverage can be less streamlined, sometimes requiring more documentation and longer processing times for claims. We’ve also noticed that its dealer network isn’t quite as extensive as some competitors, which could limit your installation and service options depending on your location. Additionally, while Bryant’s midtier models offer excellent value, its entry-level Legacy line furnaces don’t quite match the efficiency and features of similarly priced options from brands like Lennox. That said, Bryant represents an excellent sweet spot for homeowners seeking near-premium performance without the premium price tag.
Customer Reviews
Bryant’s BBB page stands out with an A+ rating and 4.94 out of 5 stars. Although the company doesn’t have accreditation, customers praise its polite installation crews and competitive pricing. Some reviews mention that issues arise with some of Bryant’s products, especially its heat pumps, after a couple of years of use.
“It was very easy to schedule an appointment with the customer service representative. Our technician was very knowledgeable and professional regarding our issue. I will continue to use Bryant heating and cooling for all my electrical needs. I would definitely recommend.” –Loraine L. via BBB in December 2024
“Our 2 year old heat pump purchased from Bryant Heating & Cooling has had service problems of a failed blower motor and faulty wiring. After 1 1/2 years, the blower motor failed. This company wanted $700 for 45 minutes of labor not covered past the one year warranty. I felt this was very excessive. They discounted the labor to $400, which I accepted because it was the middle of summer heat and we had family staying with us. Then, the unit’s wiring was not done correctly, so it blew a fuse and damaged our thermostat, which they were willing to replace with a thermostat of lesser abilities or buy a comparable thermostat for $268 discounted from over $600. I asked their manager … if they could reimburse us if we bought a comparable thermostat at Lowe’s for $179, she abruptly said no.” –Stephanie L. via BBB in November 2024
Trane Furnace
Most Years of ExperiencePrice Range: $3,500–$15,600
Warranty: 10-year standard parts limited warranty, 20-year heat exchanger
Peak AFUE: 96%
Pros and Cons
Pros
- Uses speed blower motors for quieter system startup and shutdown
- Incorporates smart-home technology for increased efficiency
- Includes a comprehensive 20-year heat exchanger warranty plus 10 years for other parts and labor
Cons
- Charges a premium for many products
- Requires a ComfortLink II thermostat on high-end options for proper function
Our Review and Insights
Trane maintains a reputation for durability, rigorous manufacturing standards, and component testing. Its S9V2 and XC95m models consistently demonstrate superior build quality, and its exclusive Vortica II blower claims to have a 20% longer operational life than standard furnace blowers. What particularly impresses us about Trane is its attention to detail in component design. Trane manufactures approximately 85% of its parts in-house rather than outsourcing, giving it outstanding quality control.
Although Trane’s limited warranty matches industry standards at 10 years for parts and 20 years for heat exchangers, its emphasis on proprietary components means replacement parts can be more expensive and sometimes take longer to source than universal components. We’ve also found that its insistence on certified Trane installers to guarantee proper installation limits your contractor options and potentially increases installation costs. Despite these factors, we believe Trane remains an excellent choice for homeowners who prioritize long-term reliability and are willing to make a larger upfront investment.
Customer Reviews
Trane is not BBB-accredited, has a B rating, and has 1.04 out of 5 stars. Customers’ experiences with Trane’s unit quality are mixed. Some mention having no issues with a unit, while others mention problems occurring after a couple of years. Most issues appear to happen with Trane’s scheduling and communication, and customers mention frequent delays.
“We have a 2 year old Trane furnace. We bought it because they are a trusted brand well reviewed by Consumer Reports. This furnace has failed 3 times already, and with every mechanical part failing. It costs us $200 in labor for every fix. … How do they maintain their reputation for quality with this level of defects? And the service company tells us if they cannot fix it this time we are SOL. Trane does nothing other than offer us a credit to buy a new one.” –Susan C. via BBB in November 2024
“We purchased our home in May 2019, which came with a Trane AC Unit (brand new build). After 5 years of living here, the evaporator coil went bad, and we were [quoted] $3k to replace the coil. They called to check [the] warranty, and as it was 5 years and a few months old, it was now outside of the 5 year warranty, so nothing. We are definitely not satisfied having an AC unit that isn’t made to last outside of 5 years, and will avoid using Trane in the future if this is the service and quality we can expect.” –Jeremy D. via BBB in August 2024
Amana Furnace
Best for EfficiencyPrice Range: $3,600–$11,000
Warranty: 10-year standard parts limited warranty, lifetime heat exchanger
Peak AFUE: 98%
Pros and Cons
Pros
- Includes a limited lifetime replacement warranty on its heat exchangers
- Adds features to improve comfort control
- Has a user-friendly website to search for dealers and find manuals and other resources
Cons
- Has average performance for its pricing
- Uses communicating technology, which is new and can be difficult to fix
Our Review and Insights
Amana combines reliable performance with excellent warranty coverage. Its AMVM97 variable-speed furnace achieves up to 98% AFUE ratings. What truly distinguishes Amana is its Lifetime Unit Replacement Limited Warranty on heat exchangers. If the heat exchanger ever fails, Amana replaces the entire furnace, not just the component. This level of coverage demonstrates remarkable confidence in its product quality, especially considering heat exchanger failure is one of the most costly furnace repairs. Amana’s ComfortNet™ communicating technology, while not as sophisticated as Carrier’s Infinity system, provides excellent temperature control and system diagnostics.
However, Amana’s more budget-friendly approach is apparent in some areas. Its blower motors, while efficient, don’t quite match the ultra-quiet operation of premium brands. You might notice slightly more operational noise, particularly during startup. We’ve also observed that its dealer network isn’t as extensive as those of larger brands, such as Carrier or Trane, which could affect your options for installation and service depending on your location. Additionally, while Amana’s midrange and premium models offer competitive features, its base models lack some of the advanced humidity control capabilities found in similarly priced units from brands like Bryant.
Customer Reviews
Amana has BBB accreditation, an A+ rating, and a star rating of 1.16 out of 5 through its parent company, Daikin Comfort Manufacturing LP. Positive reviews mention high-quality builds from Amana, especially its basic units. Like other companies on this list, negative comments focus on delays in receiving parts and difficult communication when using a warranty.
“Best bang for your buck! Simple units without the fancy bells and whistles that can go bad. When I need cooling it’s cold[,] when I need heat[,] it heats my home, what else does it need to do? I’ve owned one for 14 years and just had a new one installed last year without issues! Your installer makes all the difference in the world.” –Ed R. via BBB in November 2023
“Daikin installed January of 2023. For the first summer, ran great. However this May 2024 unit could not maintain temperature. Two tech visits with no resolution (Conditioned Air is the installer and local dealer). Third Tech diagnoses a failed EEV valve. Parts ordered and a week passes before I’m told it will be 2 more weeks to wait for parts. No timely updates from Conditioned Air. Yesterday they say parts are here and schedule today for repair. Get a call an hour ago, part arrived BROKEN and NO update on what to do next. Calls into service manager, VP of Service and no answer. Beyond frustrated.” –Marc M. via BBB in July 2024
How Much Do Furnaces Cost?
When investing in a new furnace, it’s essential to understand not just the upfront equipment costs but also the total investment required for a properly functioning heating system. A new furnace installation typically costs between $3,300 and $6,850, though high-efficiency models with advanced features can exceed $12,000 (based on averages between each provider’s online catalog, Lowe’s, and HVAC Direct).
Let’s examine the key factors influencing your total cost and explore ways to make this investment more manageable.
Cost Factors That Impact Your Total Investment
The base price of your furnace is just the starting point. Your total cost depends on several important factors that ensure optimal performance and longevity. Your home’s size is a fundamental consideration, as it determines the capacity of the furnace you’ll need. Typically, larger homes require more powerful and, consequently, more expensive units.
The furnace’s efficiency rating, measured in AFUE (Annual Fuel Utilization Efficiency), also significantly impacts the initial cost and long-term savings. Higher-efficiency models tend to have higher upfront prices, but they offer reduced operating costs over time.
Additionally, the installation’s complexity can affect your total investment. Factors such as ductwork modifications, electrical upgrades, and the need for specialized venting can all contribute to the final cost.
Financing Options To Consider
Many major manufacturers and HVAC contractors provide financing solutions to help manage the substantial investment required for a new furnace. These options typically include conventional choices, such as unsecured personal loans with terms ranging from two to seven years. Additionally, specialized HVAC financing programs may offer promotional periods with 0% interest for 12–18 months. Some utility companies also offer low-interest financing specifically for high-efficiency furnace installations. Furthermore, government programs such as the PowerSmart program provide attractive terms for qualifying energy-efficient models.
Available Discounts and Rebates
You may be able to mitigate your furnace investment through various incentive programs. Federal tax credits can provide up to $600 for installing qualified high-efficiency gas furnaces until 2032. In addition, many state and local utilities offer rebates ranging from $400–$1,000 for high-efficiency models, with higher incentives available for households meeting certain income qualifications. Manufacturer rebates are often seasonal, providing discounts of $200–$600 on select models. Additionally, some contractors may offer extra discounts during slower seasons or for early bookings of installations.
How Do You Choose the Best Furnace Brand?
Choosing the right company to install your new furnace is just as important as selecting the furnace itself.
Warranty Coverage
A reputable furnace company will provide comprehensive warranty coverage that offers you true peace of mind. The best companies typically offer a 10-year parts warranty on parts and a lifetime warranty for the heat exchanger, which is essentially the heart of your furnace. However, these warranties often require annual equipment maintenance to stay valid. When evaluating warranties, pay special attention to labor coverage, as this can save you thousands of dollars in repair costs over time.
Certification and Training Standards
The most reliable furnace companies invest significantly in their technicians’ education and certification. Look for companies whose technicians hold North American Technician Excellence (NATE) certification, which is considered the gold standard in the industry. These companies typically offer ongoing training programs to ensure their teams stay updated on the latest furnace technologies and repair techniques. This is important because modern furnaces are essentially complex computers with heating elements, necessitating specialized knowledge for proper installation and maintenance.
Installation Expertise and Sizing Methodology
A truly professional furnace company will do more than just sell you a furnace; its technicians will perform a detailed load calculation of your home, known as a Manual J calculation. This process considers various factors, such as your home’s square footage, insulation levels, window efficiency, and local climate patterns, to determine the exact furnace size you need. It’s concerning that some companies skip this vital step and simply replace your old furnace with one of the same size. This approach can lead to higher energy bills and inconsistent heating throughout your home.
Service and Maintenance Commitments
The best furnace companies see installation as the start of your relationship. The company should provide comprehensive maintenance plans that include regular tuneups, priority service during emergencies, and discounted repair rates. A reputable company will also offer 24/7 emergency service and ensure clear communication regarding appointment times and pricing. You want a company that takes your comfort as seriously as you do.
Local Reputation and Experience
While newer companies can offer excellent services, it can be comforting to partner with a business that has deep connections within your community. Seek out companies that have been serving your area for at least five to 10 years and have a strong local presence. Review their feedback across multiple platforms, but pay particular attention to how they address negative reviews. The best companies will respond professionally and make an effort to resolve any issues promptly.
Price Transparency and Financing Options
Reputable furnace companies will provide detailed, written estimates clearly outlining all costs associated with your installation. They should be willing to explain each line item and offer reasonable financing options if needed. Be cautious of companies that pressure you with “today-only” deals or refuse to give written estimates. The best companies recognize that a furnace is a significant investment and will help you make an informed decision at your own pace.
FAQs About the Best Furnace Brands
How long should a furnace typically last?
A well-maintained furnace can last between 15 and 25 years, according to the International Association of Certified Home Inspectors, although this lifespan can vary based on several factors. The quality of the initial installation is crucial—furnaces that are properly installed by reputable brands like Carrier or Trane often achieve the longer end of this range.
Regular maintenance, which includes annual professional tuneups and monthly filter changes, can significantly extend your furnace’s life. Think of it like caring for a car: The more attentive you are to its needs, the longer it will operate efficiently.
Why do furnace prices vary so much between brands?
Furnace prices vary due to differences in engineering quality, features, and manufacturing standards. Premium brands like Lennox and Carrier tend to be more expensive because they use higher-quality components and advanced technology, and they conduct rigorous testing. These brands often include features such as variable-speed blowers and modulating gas valves, which offer more precise temperature control and improved energy efficiency. Additionally, the higher price typically reflects better warranty coverage and more reliable customer support networks.
Are variable-speed furnaces worth the extra cost?
Variable-speed technology enables your furnace to operate at different speeds based on your home’s heating requirements, rather than just toggling between “on” and “off.” Although these systems may have a higher initial cost, they often pay for themselves through lower energy bills and enhanced comfort. They maintain more consistent temperatures, effectively remove more humidity, and run more quietly than single-speed furnaces. This technology is especially beneficial if you have allergies or are sensitive to temperature changes, as it provides better air filtration and more precise temperature control.
What size furnace do I need for my home?
Choosing the correct furnace size involves more than simply measuring your home’s square footage. It requires a professional calculation that takes into account factors such as your climate zone, insulation levels, window efficiency, ceiling height, and even the orientation of your home to the sun. A furnace that is too large will frequently cycle on and off, wasting energy and leading to faster wear and tear. Conversely, an undersized unit will struggle to maintain comfortable temperatures. That’s why having a professional perform a Manual J calculation for sizing is essential for optimal performance.
