How much does a new furnace cost for a 2000 square-foot house?

A new furnace for a 2,000-square-foot home is priced after an in-home evaluation because equipment and installation conditions set the total. You can begin with an $89 HVAC install diagnostic with our Next Day Guarantee, which lets the technician size the system and provide exact options.

The largest cost swing is usually the unit’s size and type, followed by how accessible the install area is. Eligible replacements may qualify for up to $3125 in federal tax credits, which can reduce your net cost. We install and replace heating systems across the Phoenix area and tailor recommendations to local homes. A right-sized unit matched to your ductwork delivers steadier heat than simply choosing a larger model.

Key factors that change the project price:

• Unit size selected for your home
• Unit type and efficiency preference
• Location and accessibility of the install area
• Optional related work, like duct repair/testing (SRP rebates up to $400) or adding a smart thermostat (SRP rebate up to $100)

Final pricing is confirmed on site after we evaluate sizing, access, and any add-ons you want.
