Yes. In Arizona a landlord must supply reasonable heat and reasonable air conditioning or cooling where such units are installed, and keep HVAC facilities in good and safe working order. That is in A.R.S. 33-1324. This is general information and not legal advice. Climate Pros Tucson is a referral service and not a law office.
What does Arizona law require?
Arizona law says a landlord must provide reasonable air conditioning or cooling where units are installed, and must keep the heating, cooling and ventilation facilities in good and safe working order. You can read the text at A.R.S. 33-1324.
The law covers equipment the rental already has. Whether a unit counts as installed, and what is reasonable, can depend on the lease and the facts, so ask a tenant rights group or an attorney if it is disputed.
Is there a temperature limit in Tucson?
In Tucson, a rental cooled by air conditioning may not exceed 82F in habitable rooms, and an evaporative-cooled unit may not exceed 86F, according to the Arizona Attorney General’s office in a May 27, 2025 release. A 2026 bill, SB 1608, proposed a statewide 82F maximum and 68F minimum. It was a proposal, so don’t treat it as the law.
Tucson summers make this matter. Tucson International Airport averages about 68 days a year at or above 100F, and a July night’s normal low is 76.3F, so an apartment without working cooling doesn’t recover on its own. See AC died in Tucson heat.
What should you do first?
Put the request in writing and keep a copy. Describe the problem and the date it started, include photos and room temperatures if you can, and ask for a repair date. Send it the way your lease says and keep proof it was sent.
- Send a written request to the landlord or property manager.
- Keep a log of dates, messages, calls and temperatures.
- Don’t stop paying rent or hire your own contractor until you have checked your rights, since either can backfire.
- Contact a tenant rights group or attorney if the problem is ignored.
The Arizona Attorney General has warned landlords about these obligations, which gives you a place to start reading. If heat is a danger to someone in the home, leave for a cooler place.
Who fixes the unit?
Repairs to equipment the landlord supplies go through the landlord. If you own a rental, a licensed pro can do the repair, and rental property HVAC maintenance in Tucson helps you avoid breakdowns. See window AC installation for rentals for the tenant side of a unit you add yourself.
Check any contractor’s license at roc.az.gov. See AC repair and the Tucson HVAC hub.
