Pool Heater Repair & Installation in North Houston

For most North Houston pools used from March to November, a heat pump costs far less to run because it works efficiently in mild air temperatures. A gas heater wins when you want the spa hot in thirty minutes on a January evening, or heat on demand for occasional use rather than all season. Many of our customers with a pool and spa combination end up with gas for exactly that reason. We ask how you use the pool before recommending either.

That pattern usually means a safety switch is tripping — most often low water flow from a dirty filter, a clogged basket or a failing pump, or a pressure switch or high-limit sensor that has failed. Clean the filter and baskets first, because that alone fixes a lot of them. If it still cycles, the error code on the display tells us where to start.

Roughly eight to twelve years for a gas heater and a little longer for a well-kept heat pump, but water chemistry matters more than age. Low pH and high chlorine eat copper heat exchangers, which is why heater failures cluster on pools with poorly balanced water. Keeping the water in balance is the cheapest heater protection there is.

Yes. Water left standing in a heater that is not circulating can freeze and crack the heat exchanger or headers, which is one of the more expensive freeze repairs. During a freeze the pump needs to keep water moving through the heater, and if power is lost for long the heater may need draining. Our freeze protection page covers what to do.
