HVAC cost guide
Most HVAC replacements run between $5,000 and $25,000 installed — a single furnace or AC at the low end, a full system or heat-pump conversion toward the top.
Use these figures to plan a budget, not as a contractor quote. Project details and local conditions can change the final price, which is confirmed during an on-site assessment.
What affects hvac cost?
System type
Replacing one component (AC or furnace) costs less than a full matched system or a heat-pump conversion.
Home size
Bigger homes need higher-capacity equipment, and sizing it right matters more than any brand choice.
Efficiency tier
Higher-efficiency equipment costs more up front and typically lowers operating costs over its life.
Ductwork and electrical
Duct repairs, modifications, or panel upgrades add scope beyond the equipment swap.
