Frequently Asked Questions 

How much does it cost to replace gas furnace?

On average, a gas furnace costs around $4,500 to replace. As always, factors such as the brand and required preparation affect the replacement cost.

How many years does a gas furnace last?

With proper maintenance, a well-built furnace will provide reliable heating for 15 to 20 years. The older the furnace, the less efficient the operation and the more costly the repairs. Moreover, while furnaces can last 20 years, it’s often advisable to replace them before then because advances in heating technology make newer furnaces significantly more energy-efficient and cost-effective to operate.

What is the best gas furnace?

A gas furnace is a considerable investment, and it’s our pleasure to help you select the best gas furnace for your needs. Our clients want well-balanced systems that will deliver superior comfort, reliable performance, and energy-efficient operation. To that end, we recommend gas furnaces manufactured by Trane, Carrier, Lennox, Bryant, and Rheem.

How important is sizing?

Sizing is just as important as choosing the right brand. Maybe even more so. If your furnace is too small, it will struggle to deliver the comfort you desire. This will increase wear and tear and cause the unit to fail. If it’s too large, you’re wasting energy and losing out on the benefits of an energy-efficient system. For these reasons, our NATE-certified HVAC technicians will help you calculate and select the correctly sized gas furnace for your home.

How does a gas furnace work?

Gas furnaces work by burning either propane or natural gas within the burner. The heat generated from combustion passes through the heat exchanger. At this point, the ductwork blows over the heat exchanger, causing it to warm. The blower then forces the warmed air into the supply ducts for distribution throughout your home.
