Schedule your Houston pool heater repair today and get back to swimming.
Your Pool Heater Isn’t Heating. Now What?
Your pool should be warm when you want to swim, and in Houston that's more months than you'd think. A cold front rolls through, you switch the heater on, and nothing happens. Or it runs all day and the water barely budges.
PoolTec provides pool heater repair for Houston homeowners whose heaters won’t heat, keep shutting off, or have stopped working altogether. We track down what’s actually wrong, fix it, and get your pool back to the temperature you set, so you can get back in the water.
The Road Back to a Warm Pool
Tell Us What’s Happening
Call PoolTec and describe what the pool heater is doing. Is it clicking, shutting off, or running without heating the water? Tell us when it started, and if you see an error code, give us that too.
We Find the Cause
A technician checks the pool heater and the equipment around it, including the pump, filter, and valves, to find out why it isn’t heating. You get a plain explanation of what’s wrong before any work starts.
We Fix It and Check the Result
Once the problem is repaired, we confirm the heater starts, runs, and warms the water the way it should. Then you can get back to swimming after your pool heater repair.
Common Causes of a Pool Heater That Won't Heat
Most pool heaters here sit idle through a long, hot summer, then get asked to work the first time temperatures drop. After months of sitting, burners get dirty, connections corrode, and control boards pick up moisture. Houston humidity doesn't help.
Whether your pool is in the Heights, Bellaire, Meyerland, or Midtown, the first cold snap after a hot summer is when a tired heater finally gives out, usually the weekend you planned to swim after a morning walk through Memorial Park.
Houston Pool Heater Issues
Gas pool heaters need a spark or hot surface igniter to light the burners. Igniters wear out, and in damp air they can corrode. Clicking with no flame points here.
A pool heater shuts down when water isn't moving through it correctly. A clogged filter, a full skimmer basket, or a failing pressure switch can make it think something is wrong, so it won't fire.
Minerals can coat the inside of the heat exchanger. The pool heater runs, but heat doesn't transfer well, so the water barely warms.
If the pool heater can't read the water temperature, it may not turn on, or it may never turn off.
Moisture, power surges, and age wear down electronics. A bad board can cause shutdowns, error codes, or a dead unit.
A tripped breaker, a closed gas valve, or an empty propane tank keeps a pool heater from starting.

We Look at the Whole System
A pool heater that won’t heat isn’t always a heater problem. A clogged filter, a weak pump, or a stuck valve can shut a heater down just the same. PoolTec checks the heater and the equipment around it, so we fix the real cause instead of swapping parts and hoping.
We Explain Things in Plain Terms
You shouldn’t need to know what a pressure switch does to understand your repair. We tell you what failed, why it matters, and what the fix involves, in words that make sense. If you have questions, ask them.
We Know How Houston Pools Run
Houston pools deal with long, humid summers, sudden cold fronts, and storm season. Those conditions are hard on heaters, and PoolTec sees the results every year. That experience helps us spot problems faster.
We Give You Straight Answers
Some problems need a fix today, and some can wait. PoolTec tells you which is which, so you can make the call with real information instead of pressure.

Pool Heater Repair FAQ
Sometimes the heater is fine and the pool is losing heat faster than it can add it. Wind, evaporation, and an uncovered pool on a clear night can all outpace a heater.
If the pump isn't moving water, the pool heater won't fire. If the pump looks normal and the heater still won't start, the heater is the likelier source.
Many last somewhere around five to ten years, depending on the type, how often it runs, and how well it's maintained.
Yes, as long as your pump and filter are working. The pool heater only affects temperature, not water quality.
Ignition and burner problems are the most common issues with gas pool heaters. Electric heat pumps tend to have compressor and fan problems.
