Before you sign
- Ask for the load calculation. The size should come from a room-by-room calculation (called a Manual J), not the size of the old unit.
- Ask what's included. Equipment, labor, permit, removal of the old unit and the startup readings, each named. Six questions worth asking.
- Read the model numbers. They say what you are actually being sold. How to read them.

Where do these numbers come from?
From 81 real quotes homeowners received, dated October 2025 to September 2026, either shared through our Quote X-Ray or published openly by the homeowner. Cost-model estimates never count, and a group is only shown once it holds 5 quotes.
How to read these numbers
- These are quotes, what a contractor proposed, not final invoices.
- The middle price is the median: half the quotes were lower and half higher. It moves less than an average when one quote is unusually high.
- 1 quote that also replaced the ductwork is left out: new ducts are a bigger job than the equipment.
- 81 quotes is a real sample, not a survey. Prices differ by region; the state pages show the states with enough quotes.
- The quotes are dated from October 2025 to September 2026.
