High-efficiency furnaces (typically those with an AFUE rating of 90 % to 99 %) are manufactured by several top-rated brands. Industry leaders offering highly efficient systems include:
Best Furnace Brands of 2026 for Efficiency, Reliability, and Value
When choosing a furnace, the best brand depends on what you prioritize: reliability, high-end efficiency, or budget-friendly value. Based on industry consensus and consumer ratings, the top three furnace brands are Carrier, Trane, and Lennox.
Average Cost to Replace a Furnace
However, the cost of furnaces can range widely depending on their size, type, and efficiency, and homeowners can generally expect a new furnace to cost anywhere between $3,800 and $10,000. If efficiency is important to you, high-efficiency models can reach up to $12,000.
A high-efficiency furnace is a heating system that converts 90% or more of its consumed fuel into usable heat.
Yes, high-efficiency furnaces (90%+ AFUE) are generally worth it if you live in a cold climate or have high utility rates. While they cost more upfront, their ability to convert up to 97% of fuel into usable heat can significantly lower your energy bills.
For a 2,000 square foot home, the cost of a new gas furnace typically ranges from $3,800 to $10,000, including professional installation. Labor alone often starts around $1,600.
The best time to buy a furnace is during the off-season, specifically late spring (April-May) or early autumn (September-October), when HVAC companies are less busy and offer lower prices, rebates, or promotions. Purchasing in these shoulder seasons ensures faster installation times and better negotiating power compared to winter peak season.
A high-efficiency furnace typically lasts 15 to 20 years. While they are built to last, their lifespan heavily depends on proper installation, regular maintenance, and the quality of the unit itself.
There are annual limits on the amount of federal tax credit you can claim for HVAC equipment, meaning you can only claim up to a certain dollar amount each year. Federal HVAC tax credits allow homeowners to claim a maximum annual credit of up to $3,200 for qualifying HVAC upgrades made between 2023 and 2025.
Electric furnaces generally have the longest lifespan, lasting 20 to 30 years due to fewer moving parts and no combustion. However, if you are looking for a standard forced-air system, gas furnaces typically last 15 to 20 years.
The $5,000 rule is a guideline to help homeowners decide whether to repair or replace their HVAC system. You multiply the age of your unit by the cost of the needed repair. If that number exceeds $5,000, replacing your HVAC system is often more cost-effective.
Among them, the top four cities—Chongqing, Fuzhou, Hangzhou, and Nanchang—were dubbed the "New Four Furnaces" by many netizens, while Wuhan dropped out of the top four, ranking sixth. There is also a claim that Jinan ranked seventh on the national "furnace" city list.
An 80,000 BTU furnace typically heats homes ranging from 1,600 to 2,500 square feet. The exact coverage depends heavily on your local climate, ceiling height, insulation quality, and the overall energy efficiency of the furnace.
Carrier and Rheem are both premier HVAC brands, but they cater to slightly different needs. Carrier leads the industry in premium, ultra-high efficiency and advanced communicating technology. Rheem is celebrated for offering a better balance of day-to-day value, long-term reliability, and easier-to-source replacement parts.
A furnace with an AFUE rating of 95% will require significantly less fuel (natural gas) to heat your home than a unit with an 80% AFUE rating. While higher-efficiency furnaces tend to cost more upfront, they allow homeowners to save money on heating costs every year.
You should probably Replace if: [ ] The repair costs more than 50% of a new unit. [ ] The furnace is over 15 years old. [ ] You have had to repair it more than once in the last 2 years.
High-efficiency furnaces may require more frequent check-ups by qualified technicians to maintain their optimal performance levels. Additionally, when repairs are needed, they can be more costly and complex due to the specialized components and technology involved.
The heat exchanger is often considered the most costly part of a furnace to repair or replace. It is a critical component that transfers heat from the combustion process to the air that circulates throughout your home. Over time, heat exchangers can crack due to the constant heating and cooling cycles they undergo.
Average Furnace Installation Cost Range
A new furnace installation typically ranges between $4,000 and $8,000, depending on system type and efficiency. This total is an all-inclusive number, including the new furnace, labor, removal of the old unit, and minor ductwork adjustments.
Yes HVAC prices have steadily increased over the past few years, and 2026 is no exception. These increases are affecting everything from entry-level systems to high-efficiency units, making it more expensive than ever to install or replace HVAC systems.
Shop around. Getting competitive bids from several contractors will save you money. For large installation jobs, it's common for company-to-company price differences to exceed $1,500 for the same equipment and work. Even for smaller installation jobs, prices vary considerably.
Yes, you should strongly consider replacing a 25-year-old furnace. While it has outlived the typical 15 to 20-year lifespan, at this age, parts fail frequently, efficiency drops dramatically, and there is an increased risk of carbon monoxide leaks.
The following are the most costly parts to fix or replace:
The Rule of 5000 Rule is simple: Multiply the cost of the needed repair by the age of your air conditioner. If the result is greater than 5000, AC replacement is generally the smarter choice. If it's less than 5000, a repair might still be worth the investment. Here's a quick example.
