How much does it cost to replace a HVAC system in a typical home?

Russett Southwest Corporation replaces home HVAC systems with financing starting as low as $120 per month, and the final price is set after an on-site evaluation. The biggest driver is matching system type and size to your home’s needs. We replace systems across the Tucson area’s desert climate, so recommendations reflect real summer conditions. Qualified installations may access local utility efficiency programs. If your current unit is unreliable or inefficient, replacement often lowers energy use and repair risk.

Typical home price varies with:

• Equipment configuration: AC with furnace, all-electric heat pump, or ductless mini-split.
• Capacity and efficiency ratings sized by a proper load calculation.
• Ductwork condition and any needed modifications or sealing.
• Installation scope: electrical, refrigerant lines, condensate, thermostat/zoning, and IAQ add-ons.
