Inside the City of Tucson, yes: replacing an AC, furnace or heat pump needs a permit, and the licensed contractor pulls it. Climate Pros Tucson matches you with a licensed local pro who builds the permit into the quote.
Does replacing my AC in Tucson need a permit?
Yes. The City’s Planning and Development Services Department lists permits for furnaces, heat pumps and air conditioners, whether new or replacement. It also lists permits for new evaporative coolers and for water heater installation, including replacement. Only new evaporative coolers are listed, so a like-for-like cooler swap is not on that list.
Load and sizing calculations are required for new and replacement HVAC equipment. That’s the City’s rule, and it’s why a quote that skips sizing is a red flag.
Who pulls the permit?
The licensed contractor does, not the homeowner and not Climate Pros Tucson. A pro who offers to skip the permit is putting the risk on you. Ask the contractor to confirm that the permit is in the quote and that an inspection follows the work.
What does the permit cost?
The City of Tucson’s fee schedule, effective July 1, 2026, lists a $150 trade permit for an air conditioner or heater repair or replacement (checked October 2026). For two or more items on one trade permit, it lists $150 for the first item plus $50 for each additional item. The fee includes up to half an hour of staff review and processing and two inspections, and extra review or inspection time is billed at the City’s hourly rate.
- Digital filing fee. The same schedule lists a separate fee of 1% of the total fee, minimum $18.54, on all activities. It’s its own line, not part of the $150.
- Work started without a permit. The schedule lists a penalty of 100% of the permit fee.
The licensed contractor pulls the permit and the fee shows up on their written quote. The written quote from the pro is the number that counts for your home.
What about work that seems too small for a licensed pro?
Arizona exempts casual, minor work under $1,000 in aggregate (labor, materials, everything), as long as the job isn’t part of a larger operation and isn’t split up to dodge the limit. That exemption goes away when the work needs a local building permit. An HVAC replacement in the City of Tucson needs one, so the handyman exemption does not cover it.
You can check a contractor’s license with the Arizona Registrar of Contractors at roc.az.gov. The residential HVAC classification is R-39 (Air Conditioning and Refrigeration, Including Solar), and there are narrower R-39R subclassifications. ROC lists what each class may do.
What if you live outside the City of Tucson?
Oro Valley, Marana, Sahuarita, South Tucson and unincorporated Pima County may each have their own permit rules. This page covers the City of Tucson’s rules only.
For addresses in unincorporated Pima County, Pima County Development Services’ fee schedule, effective July 1, 2026, lists these line items separately (checked October 2026): a $69 base fee for all permits requiring an inspection, $27 for minor mechanical work such as a residential air conditioner unit, $198 for moderate mechanical work such as multiple mechanical units or ducts, a $69 re-inspection fee, and an additional 25% of the permit fee for work started before the permit is issued. Each line stands on its own. Oro Valley, Marana, Sahuarita and South Tucson set their own fees, so ask the pro.
For any address outside the City, ask the matched pro which jurisdiction applies and what it requires, or call the building department for that town or county.

Does the energy code add anything?
It can. The City adopted amendments to the 2024 International Energy Conservation Code. Residential air leakage testing has to be done by a RESNET, BPI or other approved certifier. Ask the pro whether your project triggers testing.
What should you ask before you sign?
- Is the permit in the quote, and who pulls it?
- Is a load calculation part of the job?
- When is the inspection, and who is there for it?
- What local rules apply at my address?
