Is this AC quote fair?

What common repairs cost

Repair	Published range, installed	Source
Capacitor	$80 to $400, $175 average	This Old House, April 2026
Capacitor	$100 to $400	Fixr, January 2026
Contactor or relay	$100 to $450	This Old House, March 2026
Contactor	$150 to $400	Fixr, July 2026
Condenser fan motor	$300 to $800	This Old House, March 2026
Refrigerant recharge	$250 to $900, $400 average	Fixr recharge guide, January 2025
Refrigerant leak repair and recharge	$200 to $1,600, $800 average	Fixr, July 2026
Compressor	$600 to $3,000	Fixr, January 2026
Compressor	$1,000 to $3,000 or more	This Old House, March 2026

National published figures, not local averages and not our quote. Where the sources disagree, both are shown.

The part is usually the small share. This Old House puts the capacitor itself at $8 to $45 and says labor makes up most of the total. Fixr lists R-410A refrigerant at $12 to $25 a pound and the older R-22 at $50 to $80 a pound, which is why recharging an old R-22 system costs more.

What valley homeowners run into

We read about a hundred recent AC threads from Phoenix-area and HVAC forums before writing this. The same few stories kept coming up:

• A capacitor quoted at several hundred dollars for the part alone, plus labor. Compare that with the $8 to $45 This Old House gives for the part.
• A replacement quote in the high teens of thousands for an ordinary single-story house, from the company that had just done the tune-up. Fixr's published range for a new central system tops out at $14,400.
• Maintenance memberships where every visit finds something new to fix.
• A compressor quoted on a system only a few years old, with no mention of the manufacturer's parts warranty.

None of those is automatically a scam. Each one is a reason to ask for the itemized price in writing and get a second quote. On a newer system, ask whether the failed part is still under the manufacturer's warranty, so you only pay labor.

Red flags

The FTC's home improvement guide lists these warning signs:

• Someone knocks on your door because they are "in the area."
• Pressure for an immediate decision.
• A demand to pay for everything up front, or cash only.

The FTC also says never to make the final payment until the work is done and you are satisfied with it. I'd add two of my own: a price that jumps once the technician is in the attic, with no clear reason, and a whole new system offered for a problem the tables above put in the hundreds.

Questions to ask before you sign

1. What failed, and can you show me the part or a photo of it?
2. What is the price for that repair alone, in writing?
3. Is the diagnostic or trip fee credited if I go ahead?
4. If it is refrigerant: where is the leak, and is it being repaired or only topped off?
5. What warranty covers the parts and the labor?
6. What is your Arizona Registrar of Contractors license number? Check it at roc.az.gov before work starts.

On a big repair or a replacement, a second opinion is reasonable. You can say no to any quote.

Your right to cancel

Arizona's home solicitation law lets a buyer cancel until midnight of the third business day after signing, for sales the seller solicits at your home without a prior invitation or appointment (A.R.S. 44-5001 and 44-5002). The FTC's federal Cooling-Off Rule has a similar three-day right, but it doesn't cover a repair visit you asked for. It does cover extra items you agree to buy beyond that repair, according to the FTC. Read the cancellation notice on any contract you sign at home.

If the work goes wrong

Arizona runs a residential contractors' recovery fund for homeowners harmed by a licensed contractor. The maximum award is $30,000 (A.R.S. 32-1132.01). It only helps if the contractor was licensed, which is one more reason to check first. How to check a license.
