Quick answer
Pool heat pump service covers repair, maintenance and replacement of the heat pumps that warm pools and spas. Common problems are low refrigerant, failed fans, dirty coils, water flow faults and corroded parts. In Miami's warm climate these heaters run efficiently most of the year, and we keep them running.

Pool heat pumps use a compressor, refrigerant and a fan to move heat from outdoor air into pool water through a heat exchanger. They are efficient because they move heat rather than creating it.
Miami's climate makes them a good choice, since even winter air is usually warm enough for efficient heating. The same salt air, humidity and lawn debris that affect AC condensers affect pool heat pumps too.
We diagnose heaters that will not start, run without heating, show flow or pressure codes, or leak, and we replace units that are past saving.
