What Factors Should You Consider When Choosing a Furnace Brand?
Look out for these common factors to ensure you choose a quality unit for the high average furnace installation cost.
AFUE Ratings
Annual fuel utilization efficiency (AFUE) ratings measure how much fuel the furnace converts to heat, allowing you to gauge efficiency. A quality furnace has an 80%–99% AFUE rating. We don’t recommend buying a furnace below 80% AFUE. Though furnaces with higher AFUE ratings cost more, spending an extra $300 or $500 for better energy efficiency is worth it for long-term energy savings.
Brand Compatibility
It’s important to check what company makes your other HVAC components. HVAC brands often design their products to be compatible with only their brand or brands owned by the same parent company. Knowing the brand of your AC unit and thermostat will help you narrow down your options.
Maintenance
Pay attention to the furnace’s components and their quality. High-quality components require less maintenance, saving you money on routine HVAC maintenance. Most brands offer different tiers of heating units that fit various budgets and home heating needs. Look out for parts that use stainless steel and variable-speed technology as good markers of high quality.
Additional components such as an air pressure switch, variable-speed motor, air filtration system, and electronic ignition help with performance and maintenance. These advanced features can reduce noise, trap dust particles, and increase efficiency. Furnaces may also have smart-home features that improve efficiency by automatically adjusting the heat output to the exact amount of air needed.
Motors
Furnace motors, also known as blower motors, make the whole system run. These motors are usually connected to the blower in some capacity.
Standard furnaces have a direct drive motor that connects with the furnace’s blower wheel to circulate air through the furnace system. However, many companies now offer variable-speed motors. Unlike conventional furnace motors, a variable-speed blower motor runs at different speeds to precisely control the heat flow. This results in better airflow control and a better balance of temperature and humidity. As an added bonus, a variable-speed motor slowly ramps up to full speed, reducing noise while increasing energy efficiency.
We recommend looking for furnaces that incorporate variable-speed motors.
Packaged Systems
Packaged systems are a great way to cut costs on an entire HVAC system. HVAC companies tend to manufacture both heating and cooling units, so you might be able to purchase both unit types at a reduced price if you go through the same brand for both. For example, Bryant offers its furnaces with cooling units, such as AC units, at reduced prices. If you need an entire HVAC system replacement, we suggest you look for a company that offers packaged systems.
Warranties
Review the length of each brand’s warranties and what parts or components are covered. A 10-year limited parts warranty is standard but check and see if the brand offers additional labor warranties or unit replacement warranties.
For example, Trane includes a 10-year labor warranty to cover the cost of repairs or replacement due to malfunction, and Daikin includes a lifetime warranty on its heat exchangers. These warranties make these brands stand out compared to others offering only a 10-year parts warranty.
What Are Commonly Used Furnace Terms?
This measures a furnace’s heating efficiency. The higher the AFUE, the more efficient the furnace.
A BTU equals the amount of heat required to raise a pound of water by one degree Fahrenheit. This unit of heat determines how much heating capacity your home needs. The higher the BTU rating, the more powerful it is. Larger homes require furnaces with higher BTUs.
This refers to the system of metal or synthetic ducts used to transport heated air throughout your home. Your furnace will be integrated into your home’s ductwork.
A gas furnace converts natural gas or propane into heat for your home.
An oil furnace converts heating oil into heat for the home.
A heat exchanger is the part of the furnace that transfers heat to the surrounding air, which is then pumped throughout the home. You can think of it as the backbone of the furnace.
A heat pump is a popular home system that has both heating and cooling abilities. It draws heat from the outdoor air and circulates it through a home’s air ducts during cold months. In summer, it removes heat from the house and releases it outside.
Similar to a heat pump, a packaged system combines heating and cooling into one system that’s housed outside. These systems come in various configurations, including AC-only or heat pump options.
This motor operates at a wide range of speeds to control the distribution of heated air throughout the home. It has become increasingly popular, as it yields better energy efficiency and comfort than one- or two-stage options.
How Do You Determine What Size Furnace You Need?
Your home’s square footage and local climate will determine what size furnace you need. Furnace capacities are measured in British Thermal Units (BTUs). HVAC contractors typically allocate about 20 BTUs for each square foot of space. For example, an average 2,000-square-foot home will need between 80,000 and 115,000 BTUs to heat efficiently.
Our Conclusion
The best furnace brand depends on your budget, heating needs, and preferences. Carrier offers some of the best-performing and most reliable furnaces, while Lennox has one of the highest AFUE ratings and best energy efficiency scores. Brands such as Bryant or American Standard may be better if you want a more affordable option.
We recommend that homeowners get at least three quotes from different brands to compare costs, warranties, and additional features.
FAQ About the Best Furnace Brands
What is the most energy-efficient furnace for homes?
The most efficient furnace is a modulating variable-speed furnace with about a 98% AFUE rating. Almost every HVAC manufacturer offers a variation of this furnace type. However, it’s one of the most expensive options, and only some homes can support it depending on duct system design and other factors. We recommend consulting a furnace technician about installing a variable-speed furnace.
Which furnace has the best warranty?
Trane has some of the best furnace warranties available. The company offers a comprehensive combination of warranties when you register its products, including a 20-year heat exchanger warranty, a 10-year limited parts warranty, and a 10-year labor warranty.
What type of furnace lasts the longest?
Oil furnaces last the longest, with an average life span of about 25 years. Gas furnaces last only 15–20 years.
What's the best furnace company?
Carrier is one of the oldest and highest-quality furnace companies in the United States. It offers affordable products that balance high efficiency, performance, and durability, including variable-speed blowers, adaptable-speed technology, and a fully insulated cabinet.
Our Rating Methodology
We are committed to providing comprehensive and unbiased reviews to our readers. This means earning your trust through transparent reviews and data to support our ratings and recommendations. Our rating system for HVAC providers is on a 100-point system based on seven factors:
- System cost (20 points): We determine each brand’s average price range for a full-size AC or furnace. Most units cost between $3,100 and $8,500. The lower the average price range, the more points a company receives.
- Efficiency rating (20 points): We consider the company’s best available energy efficiency ratings, namely its highest Seasonal Energy Efficiency Ratio (SEER) and Annual Fuel Utilization Efficiency (AFUE) ratings. The higher the rating, the higher the score.
- Sound rating (10 points): We analyze a company’s lowest possible sound rating in decibels. Companies with lower sound ratings are rated higher.
- Warranty options (10 points): We award the most points to companies with warranties above the average five- or 10-year warranties. We deduct points from companies with warranties that cover three or fewer parts.
- Energy Star certification (10 points): We award more points to companies with Energy Star-certified products.
- Reputation (10 points): We review how each company is scored on the Business Better Bureau (BBB). We deduct points for any alerts or pending lawsuits.
- Customer service and resources (20): We consider each company’s available customer support and resources. This includes whether the company offers a user-friendly product search tool, FAQ section, pricing guides, online manuals, and a mobile app.
