Hiring in Maricopa County

Not every pool contractor installs every type of heater. Before hiring, confirm that the contractor installs or services the heater you want (heat pump, gas or solar), get 2–3 written quotes, check the license on the ROC contractor search and ask who will pull the permit.

Frequently asked questions

How do I check that a Maricopa County pool contractor is licensed?

Search the contractor's license number or business name on the Arizona ROC contractor search. Look for a current, active status and a license class that fits your job (for example B-5, B-6, KA-5 or KA-6 Swimming Pools, or C-6, CR-6 or R-6 Swimming Pool Service and Repair), and make sure the business name on your contract matches the license record.

Can a pool contractor install or repair my pool heater?

Many can, but not all. The businesses listed here hold Arizona ROC swimming pool, pool service or solar plumbing licenses, and the license class alone doesn't tell you which heaters a company works on. Gas lines and electrical circuits may involve other licensed trades. Ask each contractor whether they install and service the specific heater type and brand you want. See our hiring guide.

Do I need a permit to install a pool heater in Maricopa County?

Rules vary by city and county. Installing new equipment often involves building, electrical, plumbing or gas permits, so check with your local building department. Your licensed contractor normally applies for the permit; ask for the permit number and keep the final inspection record.

Heat pump, gas or solar: which is best?

Each has trade-offs. Gas heaters heat quickly and hold temperature in any weather; heat pumps usually cost more up front but have lower running costs; solar has low operating costs but depends on sunshine. Read our heat pump vs. gas guide.
