Frequently asked questions
How much does furnace installation cost?
It depends on your existing ductwork, the size of your home, and the equipment you choose. Every new installation includes a free estimate, and any diagnostic visit is a flat $69.
Do I always need a full replacement?
No. Many furnace problems come down to a single failed component. We test and document the actual issue first — if a repair is the better value, that’s what we’ll recommend.
How long does an installation take?
Most residential furnace installations are completed in a single day, including removal of the old unit and full testing.
