The cost of a new furnace might make you balk at first thought, but with modern manufacturers offering an extremely diverse range of options with varying AFUE ratings, optional accessories, and more, there is a furnace to meet any budget! It’s just important that you work with the right service team and experts that will work with you rather than try to “sell” you.
If you need a furnace repaired or an air conditioner serviced, we'll send a local technician out to diagnose the specific problem and recommend solutions for you and your family. There will be a diagnostic fee for the visit, and any specific repairs will be an additional charge. If replacing your system is the best solution, the fee for the diagnosis will be credited toward the purchase and install of a new system.

Furnaces and thermostats are not mix-and-match appliances. Using the wrong type of thermostat with a furnace will cause operating problems and can be dangerous.
