Use the Free Repair vs Replace CalculatorOur Mission
HVAC repairs and replacements are among the most expensive home maintenance costs - averaging $350 per repair visit and $5,500-$12,000 for full system replacement. Yet most homeowners get contractor quotes without any way to know if the price is fair or the recommendation is sound.
HVACFixCalc exists to fix that. We build free, no-signup calculators that give homeowners the same information HVAC professionals use - so you walk into every service call informed.

Data Sources
Our figures are estimates built from typical national price ranges for common repairs and a regional labor-cost multiplier. They are not quotes and are not taken from a survey of contractors. For context we draw on these kinds of references:
- Repair costs: Typical national price ranges for common repairs (an estimate, not a survey of our own)
- Electricity rates: U.S. Energy Information Administration (EIA) state averages, updated annually
- SEER efficiency math: ACCA (Air Conditioning Contractors of America) Manual J methodology
- Refrigerant prices: Typical published market ranges (estimates)
- Labor indexes: Regional labor-cost multiplier informed by public construction wage data
Accuracy Commitment
Our figures are estimates. Real quotes can be well above or below them depending on your system, location and contractor, so always get local quotes. We review formulas and figures when we notice major market changes (such as refrigerant phaseouts).
If you find an error or have data that would improve our estimates, please contact us. We take accuracy seriously.
