Amana (part of Goodman) offers many midrange, quality furnaces. It provides 22 different furnaces with varying AFUE ratings and features.

Price range: $3,000 to $7,000
AFUE rating: Up to 98%

What We Like

It also uses a modulating gas valve design that allows for operation between 40% and 100% to continuously meet your specific heating needs, while the variable-speed motor technology ensures a steady stream of perfect warmth and superior humidity control—together providing optimal comfort levels.


What to Look for in a Furnace Brand

Multiple factors determine which furnace is right for your home. Below, we summarize some of the most important things to consider when HVAC shopping.

Customer Service

Regarding furnace brands, strong customer service can make all the difference. Top brands like Carrier, Trane, and Lennox invest heavily in customer support infrastructure and training. They offer extended warranty options to provide continued peace of mind. Their websites feature DIY maintenance tips and troubleshooting guides. Many have online chat, email, and phone customer service available 24/7 in case issues arise.

Some brands, like Rheem, even have a network of local dealers that can provide hands-on assistance. Overall, reputable furnace manufacturers realize that good customer service increases brand loyalty and recommendations. They strive to make the process smooth and painless, from purchase to installation to long-term maintenance. With something as vital as home heating, customers appreciate brands that stand behind their products and put service first.

Intelligent Heating

Leading furnace manufacturers offer intelligent heating features for smart-home integration. Internet-connected furnaces provide energy monitoring, custom scheduling, advanced diagnostics, and over-the-air software updates. More advanced models leverage artificial intelligence (AI) and self-learning algorithms to optimize efficiency. Key smart features include If This Then That (IFTTT) integration, voice control via Alexa or Google Home, and smart sensors that adjust runtimes based on occupancy. While smart furnaces come at a premium cost, the benefits include greater control, reduced energy bills, and added peace of mind.

Noise

A noticeable noise level is a common complaint of furnaces. A noisy furnace can disrupt your sleep and day-to-day life and disturb your pets.

We advise checking the noise level of the furnaces that interest you. Some manufacturers create furnaces that range from 50 dB to 60 dB. We recommend looking for furnaces under 70 dB. To give you a better idea of how loud this is, check out the following breakdown from Purdue University’s Chemistry Department:

Type

There are a few main options to consider when choosing the right furnace:

Variable-Speed Motors

We suggest purchasing a furnace with a variable-speed motor. Though a variable-speed heating system costs more up-front, the investment is worth it because it lowers your energy bills and increases your home’s value. A variable-speed motor adjusts its speed and airflow output based on current climate conditions. So when just a little heat is needed, it runs at lower capacity. But if you crank up the thermostat, it shifts to a higher gear to rapidly warm your home. This flexibility leads to outstanding temperature control and savings on energy bills.

​​Warranty 

Check each furnace’s warranty options. Some furnace warranties only cover certain parts of the unit, such as the heat exchanger, while others may include entire unit replacement. Each warranty may have varying lengths, too. Check the manufacturer’s website for information and see if the brand’s network of installers include a workmanship warranty.


How to Hire a Furnace Installer

We don’t recommend trying to complete a do-it-yourself (DIY) furnace installation because it’s a complicated and dangerous job. Professional furnace installation ensures a safe, quality furnace replacement. Many furnace brands have a network of certified installers. Check if the brand you’re interested in offers an authentication and credential process for HVAC installation technicians.

Furnace Energy Efficiency

Energy efficiency is vital to the heating and cooling industry because it uses various ratings and metrics to determine a product’s efficiency. The two most important ones for a furnace are the AFUE rating and ENERGY STAR certification.

What Is an AFUE Rating?

The AFUE rating indicates the percentage of fuel converted into usable heat energy. The higher the AFUE, the more efficient the furnace. Modern furnaces typically range from 80% AFUE on the low end to 98.5% AFUE for top-tier condensing models. When shopping for a new furnace, prioritize the highest AFUE rating you can afford. 

What Are ENERGY STAR Ratings?

Search for furnaces with ENERGY STAR certifications. This certification means the unit matches federally mandated guidelines regarding energy efficiency set by the U.S. Environmental Protection Agency and the U.S. Department of Energy. For gas furnaces, ENERGY STAR requires an AFUE rating of at least 95% and an AFUE of 90% for oil furnaces.


Our Recommendation

The best furnace brand depends on your energy goals and budget. We recommend Lennox to our readers due to its incredibly high AFUE ratings, smart-home capabilities, and cutting-edge technology. However, Carrier also offers well-rounded heating options, and York builds some of the most durable and quietest furnaces. 

You should get at least three quotes from different furnace brands to compare costs, warranties, and additional features. Use our tool below to request free quotes from reputable HVAC installers near you.


Furnace Brands FAQ

Which furnace lasts the longest?

Gas furnaces generally have the longest life span compared to other types of furnaces. They last around 20 to 30 years with proper maintenance and installation. Regular tune-ups, filter changes, and cleaning also help maximize this life span.

What is the best time of year to buy a furnace?

The best time to buy your furnace is in the spring when they’re not in demand. Around May, the prices will be lower, and you can splurge on a better-quality, more efficient model.

How long does it take to replace an existing furnace?

Furnace replacement typically takes one to two days to fully complete. On the first day, HVAC technicians disconnect and remove your old furnace and other components, such as ductwork and other gas or electrical connections. They’ll then install the new furnace unit and reconnect all ductwork. The second is used to complete any unfinished work and make final adjustments.

Does a new furnace increase home value?

Yes, installing a new furnace can increase a home’s value, especially if it replaces an old, inefficient model. New furnaces increase home value by roughly 5% to 10% of the total value of your home.


How We Chose the Top HVAC Brands

We researched dozens of HVAC brands to determine which ones offer the best air conditioners, heat pumps, furnaces, and other heating, ventilation, and air conditioning products. We then crafted a rating system based on each brand’s mid-tier and high-end product offerings.

We analyzed each company’s product specifications, SEER ratings, AFUE ratings, and their best available sound rating. We also ensured that each brand offers ENERGY STAR-certified products. In addition, we closely analyzed each company’s warranties to ensure their product and labor guarantees match or exceed industry standards. 

Finally, we assessed the manufacturer’s years of experience and customer reputation on popular review sites such as the Better Business Bureau. We also checked whether the brand fulfills the high-end and luxury needs of Architectural Digest readers, such as smart-home integration options, solar-powered capabilities, and home comfort control products such as air purifiers and humidity control.
