HVAC System Replacement FAQ
How much does it cost to replace an HVAC system?
A full replacement typically runs $5,000–$15,000 installed, set mostly by home size (tonnage) and efficiency. Our estimator ranges it by your home's square footage and the efficiency tier you choose.
What size HVAC system do I need?
Sizing is by cooling load, not just square footage, roughly one ton per 500–600 square feet as a starting point, refined by insulation, windows, and climate. A pro should do a load calculation, not just match the old unit.
Is a higher SEER2 rating worth it?
In hot climates with long cooling seasons, a higher-efficiency unit pays back through lower bills and often qualifies for rebates. In milder climates the payback is slower, so a standard-efficiency unit can be the better value.
