Pool Heater & Heat Pump Specialists in California

These licensed businesses put heaters, heat pumps or heating in their business name, which suggests they install and service pool heating equipment. Only a few businesses do, so licensed C-53 swimming pool contractors who don't mention heaters in their name are worth asking too. Always confirm the heater type they work on.

Why choose this

  • A business that names heaters or heat pumps is likely to install and repair them regularly.
  • Can compare heat pumps and gas heaters for your pool, usage and fuel options.
  • Often familiar with the electrical and gas connections a heater install needs.

Things to consider

  • Few businesses name pool heating explicitly, so you may need to look beyond this list.
  • A specialist may favor the heater type or brand they sell most; ask for options.
  • Busy in fall and spring, so book installs and repairs early.

Questions to ask

  • The contractor's CSLB license number, so you can confirm it on CSLB's Instant License Check.
  • Who pulls the permit (and any separate electrical, plumbing or gas permit) and whether permit fees are included.
  • The heater make, model and output, and how they sized it for your pool. Ask them to show the calculation.
  • Warranty terms: manufacturer warranty on the equipment and the contractor's own warranty on labor.
  • Heat pump vs. gas for your pool, and the trade-offs in heat-up speed and running cost.
  • Whether your existing pump, plumbing, electrical panel or gas supply needs upgrades.

Also worth asking: pool equipment service & heater repair (291)

Only a few businesses name pool heating in their name. These California-licensed swimming pool contractors name service, repair or maintenance instead, so they may also be able to help. They don't specifically advertise pool heaters or heat pumps in their name, so ask whether they install or service the heater type you want.

Frequently asked questions

Can a regular pool company install a pool heater?

Often, yes. CSLB's C-53 Swimming Pool classification covers constructing swimming pools, spas and hot tubs, including installing solar heating equipment. Gas piping and electrical work may need other licensed trades, so ask who will do that part of the job. See our hiring guide.

Should I choose a heat pump or a gas heater?

It depends on how you use the pool. Gas heaters heat quickly and can hold temperature in any weather, which suits pools used occasionally. Heat pumps usually cost more to buy but have lower running costs, and they work best when the air is mild. Our heat pump vs. gas guide covers the trade-offs.
