Miami pool season never really ends — unless your water gets cold. When night temperatures drop into the low 70s, an unheated pool can sit unused for weeks. A good heater changes that, and the first question every homeowner asks us is the same: how much does it cost, and is mine worth repairing?

Heat pump or gas heater?
Heat pumps are the most popular choice in South Florida. They move heat from the air into your pool water instead of burning fuel, so they cost far less to run month to month. We install and repair Rheem heat pumps, including the Rheem CrossWind V — a quiet, high-efficiency model built for Florida weather. Gas heaters heat water faster and suit spas or pools used on short notice, but they cost more to operate. If you swim several times a week, a heat pump almost always wins on total cost.

What does installation cost?
At DG Pool Supply, heat pump installation starts at $3,500, including the unit and professional installation. You can get an instant estimate any time with our online quote tool: https://dgpoolsupplyandservice.com/get-a-quote/
Final pricing depends on your pool size, electrical setup, and the model you choose — and we always confirm the full quote before any work begins.

Repair or replace?
A heater that is under 8–10 years old with a single failed part is usually worth repairing. Replacement makes more sense when the unit needs repeated repairs, the heat exchanger is corroded, or efficiency has dropped so much that your power bill shows it. We check heaters honestly and tell you which route saves you money — repair and replacement are both work we do every week across Kendall and Miami-Dade.
