What is the $5,000 rule for AC units?
It's a trade rule of thumb, not a promise. Multiply the unit's age by the repair quote. If the result tops $5,000, price a replacement next to the repair before you decide. Get both as separate written quotes.

How it works
How does Climate Pros Tucson work?
One call gets your request to a licensed pro who covers your part of town. You deal with that company directly, and you hire and pay it yourself.
- Call or send the form. Tell us the address, the type of system (refrigerated AC, heat pump, gas furnace, mini split or swamp cooler), where it sits (roof, ground pad, closet or attic) and what it's doing.
- We match you with a licensed local pro. Every pro we send is licensed. You can check any contractor yourself at roc.az.gov.
- The pro confirms timing and price. Ask what the diagnostic fee is and whether it applies toward the repair. Each company sets its own policy, and you hear the price before any work starts.

What makes HVAC different in Tucson?
Long, very hot summers, a humid monsoon and short, mild winters. Tucson International Airport averages about 2.6 cooling degree days for every heating degree day (1991-2020 normals), so an air conditioner here does most of the year's work.
About 68 days a year at 100F or hotter at Tucson International Airport (1991-2020 normals)
112 days at 100F or hotter in 2024, the record. The previous record was 108 in 2020
Jun 15 to Sep 30 the official monsoon window. In July and August, average dew points jump from the 20s into the high 50s
Fewer than 12 nights a year at or below freezing at the airport, on average
What usually breaks in a Tucson summer?
Long run cycles in the heat are hard on the outdoor unit's electrical parts. The usual failures are a capacitor or contactor, a condenser fan motor, a refrigerant leak, or a coil that freezes when a dusty filter starves it of air. The City of Tucson sizes equipment for a 105F summer design temperature, so on a 110F day even a healthy system may run nonstop. Our AC repair page walks through the checks to make before you call.
Roof package unit or split system?
A Tucson home can have either one. A package unit holds everything in one cabinet, often on the roof. A split system puts a condenser outside and an air handler or furnace inside. Tell us which you have, because it changes access, the replacement options and the quote.
Why does monsoon season matter?
The National Weather Service's monsoon window runs June 15 through September 30. It brings dust storms, power interruptions and a jump in humidity. Filters and outdoor coils load up with dust, condensate drains work harder, and swamp coolers lose much of their punch once dew points climb. See our swamp cooler vs AC guide for the trade-offs.
Does anyone in Tucson need real heating?
In the basin, not much: no normal day at the airport stays below freezing, and the all-time record low is 6F. Mount Lemmon is different. The station near Summerhaven logs about 4,024 heating degree days a year, roughly three times the airport, and about 53 freezing nights. Our furnace repair page covers the first cold night of the season.
Heat pumps
Should a Tucson home have a heat pump?
For most homes in the Tucson basin, a heat pump is the sensible default. Heating duty is mild, with fewer than 12 freezing nights a year at the airport and a City of Tucson winter design temperature of 35F, and the same unit does the cooling the home needs anyway. On Mount Lemmon and in Summerhaven, a cold-climate heat pump or backup heat is a question for the pro.
- Defrost on cold, damp mornings is normal. A puff of steam from the outdoor unit for a few minutes is not a fault.
- Aux heat (backup electric heat) draws far more power than the heat pump. Keep it from running through TEP's winter peak, weekdays 6 to 9 a.m. and 6 to 9 p.m., October to April.
- ENERGY STAR certified air-source heat pumps meet at least SEER2 15.2 and HSPF2 7.8. That's the ENERGY STAR level, not the legal minimum.
Compare options on our heat pump service page and in heat pump vs AC and furnace.
TEP rates and rebates
What TEP rebates and peak hours should you know about?
TEP's Efficient Home Program is an instant rebate taken off the price when you hire a participating contractor. As listed by TEP in October 2026: up to $720 for a heat pump quality installation, up to $600 for an AC quality installation, up to $300 for duct sealing, up to $100 per ton for a mini split and up to $160 total for an AC tune-up. It applies when you retire an older working unit or a non-working AC. Amounts change, so confirm with TEP or the contractor at quote time.
On TEP's Time-of-Use plan, summer on-peak runs May to September, Monday to Friday, 3 to 7 p.m. Cooling the house before 3 p.m. and letting it drift during peak moves use out of those hours. If Trico Electric Cooperative sends your bill (parts of northwest Tucson and Marana, south to Green Valley and Sahuarita), check with Trico instead. The federal 25C credit doesn't cover a system installed in 2026, and Arizona has no state HVAC tax credit. Details on our rebates and financing page.
Hiring a contractor
How do you check an HVAC contractor's license in Arizona?
Look the company up with the Arizona Registrar of Contractors at roc.az.gov before anyone starts work. Every pro we send is licensed, and it still takes two minutes to check.
- Confirm the license is active and covers the work. For home heating and cooling, the broad class is R-39 Air Conditioning and Refrigeration, Including Solar; narrower R-39R subclasses cover parts of the trade, such as warm air heating, evaporative cooling and ventilating.
- Don't hire under the handyman exemption for a replacement. It covers only casual, minor work under $1,000, and it doesn't apply to work that needs a permit. A new or replacement AC, heat pump or furnace in the City of Tucson needs one.
- Ask who handles the refrigerant. Technicians who service equipment that could release refrigerant must hold EPA Section 608 certification.
- Get the quote in writing, with model numbers, the permit and the load calculation listed.

Common questions
What do Tucson homeowners ask about HVAC?
A few of the questions people ask before they request a match. Don't see yours? Call us at (520) 353-2520.
All FAQsWhat should I check before I call for AC repair?
Make sure the thermostat is set to cool and has power, check the breaker and the disconnect by the outdoor unit, and look at the filter. Check whether water is backing up at the indoor unit, since a float switch on the condensate line can shut cooling off. If the outdoor unit hums without starting or a breaker trips again, leave it off and call.
How fast can a pro get to my house?
Climate Pros Tucson is a referral service. Call (520) 353-2520 with your address, system and symptoms. The licensed company you are matched with confirms whether it can take the job, when it can come and what it charges. We do not promise an arrival time.
How much does a new AC cost in Tucson?
It depends on the size from a load calculation, the equipment, ducts, electrical work, the permit and whether the unit sits on the roof or the ground. The City of Tucson requires a load and sizing calculation for new and replacement equipment. Ask for model numbers, scope, the permit and warranty terms in writing. Climate Pros Tucson does not set contractor prices.
Swamp cooler or refrigerated air?
A swamp cooler works best when the air is dry, which describes most of Tucson's year. In July and August, average dew points at the airport jump into the high 50s, and a cooler loses much of its punch. Refrigerated air or a heat pump keeps working through the monsoon.
Do I need a permit to replace my AC in Tucson?
Yes. The City of Tucson requires permits for new or replacement air conditioners, heat pumps and furnaces, and a load and sizing calculation for that equipment. The licensed contractor you hire pulls the permit.
