How a pool heat pump works
A heat pump does not burn fuel. It works like an air conditioner in reverse: a fan pulls warm outdoor air across a coil, refrigerant absorbs that heat, a compressor concentrates it, and a heat exchanger passes it into your pool water.
That design is efficient in Florida's mild climate, but it means several systems have to work together: water flow, airflow, refrigerant pressure, sensors and the control board. Heat pump repair is about finding which one has stopped doing its job. For gas heaters, see pool heater repair.
Error codes, grouped by what they usually mean
Every manufacturer uses its own codes. Write down the exact code, but it helps to know the families they fall into:
| Code family | What it usually means | Worth checking first |
|---|---|---|
| Flow or water pressure | The unit does not sense enough water moving through it | Pump running, filter clean, valves open |
| High refrigerant pressure | Heat is not being carried away fast enough | Water flow and filter |
| Low refrigerant pressure | Low charge, a leak or poor airflow over the coil | Airflow clearance around the unit |
| Sensor or thermistor | A temperature sensor reads out of range or has failed | Needs a pro to test |
| Defrost or ice | The coil is icing faster than it can clear | Air temperature, fan operation |
Before you request a repair
Check the flow
Make sure the pool pump is on and the filter is clean. Low flow causes more heat pump shutdowns than anything else.
Give it air
Clear plants, fences and debris from around the unit and from the fan on top. Heat pumps need open air to work.
Look at the fan
If the fan does not spin when the unit calls for heat, note it for the pro.
Check the settings
Confirm the set temperature is above the water temperature and the unit is in heat mode.
Refrigerant and electrical repairs are not do-it-yourself jobs. Leave them to a qualified pro.
Repairs pros commonly make
- Water pressure or flow switch replacement
- Temperature sensor and thermistor replacement
- Fan motor or fan capacitor replacement
- Compressor contactor or capacitor replacement
- Control board and display repairs
- Refrigerant leak repair and recharge
- Coil cleaning and straightening damaged fins
- Heat exchanger leak repair
What affects heat pump repair cost
We do not list prices. The main factors are which part failed, whether refrigerant work is involved, the brand and age of the unit, and how quickly parts can be sourced. On an older unit with a failed compressor, ask the pro to compare repair with a new heat pump. Before work begins, confirm that the pro you hire holds the Florida license your job requires.
Heat pump questions
How do I find pool heat pump repair near me?
Send a request with your city, the brand if you know it, any error code and what the unit is doing. Dominion Pool Pros passes it to an independent local pro who repairs pool heat pumps in your area.
How much does pool heat pump repair cost?
It depends on the fault. Clearing a flow problem or replacing a sensor or switch is a smaller job than work on the compressor, fan motor or refrigerant system. The brand, age and parts availability also matter. Ask for a written quote, and if the unit is older, ask the pro to compare repair with replacement.
Why is water dripping from my heat pump?
Often it is normal. Heat pumps pull moisture from the air and produce condensation, sometimes a lot on humid Florida days. To check, test the dripping water for chlorine. If it has none, it is likely condensation. If it does, there may be a leak in the heat exchanger or plumbing.
My heat pump runs but the pool is not getting warmer. Why?
Heat pumps heat gradually and work less well when air temperatures drop. Beyond that, common causes are low water flow, a dirty filter, blocked airflow around the unit, a fan problem, a sensor fault or low refrigerant. A pro can check pressures and temperatures to narrow it down.
Is ice on my heat pump a problem?
Some frost on cool mornings can be normal, and many units defrost on their own. Heavy ice that does not clear, or ice on a mild day, can point to low refrigerant, a fan problem or a sensor fault and should be checked.
