Pool heater & swimming pool contractors in Merced County

Search the contractor's license number or business name on the CSLB Instant License Check. Look for a current, active status and the classification that fits your job (C-53 is Swimming Pool), and make sure the business name on your contract matches the license record.

Many can, but not all. CSLB's C-53 Swimming Pool classification covers building pools, spas and hot tubs, including installing solar heating equipment. 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.

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.

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.
