It runs but the water stays cold
The fan or burner runs but the temperature doesn't climb. Low water flow, a dirty coil or the wrong settings are common causes.

01 / The symptoms
Signs your pool heater needs repair
What pool owners usually notice first.
It won't turn on
Blank display, no fan, or a gas heater that won't light. This can be power, flow, a safety switch or the control board.
It shows an error code
Flow, pressure and sensor errors are the most common. Write the code down or take a photo; it speeds up the diagnosis.
It turns on and off over and over
Short cycling often points to low flow from a dirty filter or a pump running too slowly.
Water under the heat pump
Some water is normal condensation on humid days. Water that keeps pooling with the unit off may be a leak.
Gas smell or soot
Turn the heater and gas supply off and contact your gas utility first. Don't run a gas heater that smells of gas.
02 / The work
What we do
We check the heater and the system that feeds it: the pump, filter, valves and controls.
Diagnose gas pool heaters and electric heat pumps
Check water flow, pressure and flow switches
Test temperature sensors, thermostats and control boards
Inspect ignition and burners on gas heaters
Clean coils and check airflow on heat pumps
Inspect heat exchangers for scale and damage
Advise on repair versus replacement when a heater is near the end of its life
Equipment we work on
We work on major pool equipment brands, such as Jandy, Pentair, Rheem and Gulfstream.
03 / Good question
Why did my heat pump stop heating?
The most common reasons are low water flow (a dirty filter, a closed valve or a pump running too slowly), a thermostat set too low, a dirty or blocked coil, or a sensor or control fault. Heat pumps also heat more slowly on cool nights because they draw heat from the air.
Before you call, check that the pump is running, the filter is clean and the set temperature is above the pool temperature. If it still won't heat, we'll test it.
04 / Good question
Can you repair pool heaters?
Yes. We repair both gas pool heaters and electric heat pumps, including flow and pressure switches, sensors, ignition, control boards and heat exchanger problems. If a heater has a major failure and is near the end of its life, we'll say so and quote both a repair and a replacement.

05 / Good question
How do I reset my pool heat pump?
Most heat pumps can be reset by turning the unit off at its control panel, switching off the power at the breaker for a few minutes and then turning it back on. Check your owner's manual, because the steps vary by model. Make sure the pump is running and the filter is clean before you restart it.
If the same error comes back after a reset, the heat pump is telling you something is wrong. Leave it off and book a repair.
06 / Good question
How much does pool heater repair cost?
It depends on the part. Sensors and switches are smaller jobs, while control boards and heat exchangers cost more. We quote after diagnosing the heater, and the estimate is free.
07 / Good question
How much does a pool heat pump cost to run?
Running cost depends on the size of the pool and heat pump, the temperature you set, how cool the nights get and whether you use a pool cover. A cover and a sensible set temperature make the biggest difference.
Our winter pool heating tips cover the details, and our heat pump and gas heater buying guide helps if you're choosing a new unit.

Simple fixes are quoted on the spot and can often be done the same visit. Bigger repairs and replacements come with a free written estimate that compares the cost of fixing what you have with replacing it, so you can decide before we start.
We repair it and test the system
Once you approve, we make the repair, run the system and check that everything is working together: pump, filter, heater and controls.

Common questions from Miami pool owners
Why is my pool heater running but not heating?
Low water flow is the most common cause, from a dirty filter, a closed valve or a pump running too slowly. A dirty coil, wrong settings or a failed sensor can also stop it heating.
Can you repair pool heaters?
Yes. We repair gas pool heaters and electric heat pumps, and we'll quote a replacement too if a heater is near the end of its life.
How do I reset my heat pump?
Turn it off at the control panel, switch off the power at the breaker for a few minutes and turn it back on, following your owner's manual. If the error returns, book a repair.
Why does my heat pump heat slowly at night?
Heat pumps draw heat from the air, so they work more slowly on cool nights. Using a pool cover helps keep the heat you've gained.
Is water under my heat pump a leak?
Not always. Heat pumps produce condensation, especially on humid days. If water keeps pooling while the unit is off, have it checked for a leak.
Should I repair or replace my pool heater?
If it's a sensor, switch or ignition part, repair is usually worth it. If the heat exchanger has failed on an older heater, replacement is often better value. We compare both in writing.
