Pool heat pump repair in Jacksonville
Pool heat pumps that won't heat, show flow or pressure errors, or keep shutting off, diagnosed on both the refrigeration side and the water side.
Quick answer
Why is my pool heat pump not heating in Jacksonville, FL?
A pool heat pump in Jacksonville usually stops heating because of low water flow tripping the flow or pressure switch, a dirty filter, a failed fan motor or capacitor, a refrigerant leak, or a control fault. Checking water flow first often solves it; refrigeration problems need a technician.
Warning signs
Signs your pool heat pump needs repair
Runs but water stays cold
Low refrigerant, a failed compressor or wrong settings.
Flow or pressure error
Low water flow from a dirty filter, closed valve or pump issue.
Fan runs, compressor doesn't
A failed capacitor or compressor.
Unit shuts off repeatedly
High or low pressure safety trips.
Ice on the coil
Low airflow, low refrigerant or very cold air.
Water leaking from the unit
Condensation is normal; a leak from plumbing isn't.
Overview
Two systems in one box
A pool heat pump has a refrigeration circuit, like an air conditioner, and a water circuit connected to your pool plumbing. Many problems start on the water side: low flow from a dirty filter or a closed valve trips a safety switch, and the unit won't heat. Those are quick fixes once found.
When the water side checks out, we test the refrigeration side: fan motor, capacitor, compressor, refrigerant pressures and the heat exchanger. Controls and sensors can also fail. We find the cause, price the repair in writing, and on older units give you a replacement price alongside.
What we fix
Pool heat pump not heating
When the unit runs but the water doesn't warm, we check the settings first, then the refrigerant pressures and the compressor. A slow refrigerant leak gradually reduces heating until the unit barely warms the water. A failed compressor or capacitor stops heating altogether. We also check that the heat exchanger isn't scaled or blocked, since water chemistry problems can coat it and reduce heat transfer over time. You'll know which part failed and why before we replace it, and what the repair will cost.
Flow switch errors
Pool heat pumps won't run without enough water flowing through them, and a flow or pressure switch enforces that. A dirty filter, a closed or misaligned valve, a clogged skimmer basket or a weak pump can all trip it. We check the whole water path, clean or adjust what's needed, and test the switch itself, since a failed switch can report low flow even when flow is fine. We'll show you what to clean regularly so the error doesn't return, which saves a service call next time.
Pool heat pump refrigerant leak
Refrigerant leaks on pool heat pumps often occur at the heat exchanger, fittings or the outdoor coil, which faces sun, salt and pool chemicals in the air. We locate the leak, repair it where it's repairable, pressure test, evacuate and recharge. A leak inside the heat exchanger can let water into the refrigeration circuit, which is a serious problem, so we check carefully before recharging. If the heat exchanger is compromised, we'll price replacement honestly rather than recharging a unit that will fail again. You'll see the test results before deciding.

Pool heat pumps and coastal air
Pool heat pumps sit outdoors year-round beside pools that fill the air with moisture and chemicals, and in Jacksonville that adds to the humidity and, near the coast, salt. Those conditions are hard on the outdoor coil, fan motor and electrical terminals. Keeping the unit clear of plants, rinsing the coil gently and keeping chemicals stored away from it all help it last.

FAQ
Pool heat pump repair questions
Why does my pool heat pump show a flow error?
Usually low water flow from a dirty filter, closed valve or clogged basket.
Is water under my pool heat pump normal?
Condensation is normal; water from the plumbing isn't.
Why isn't my pool heat pump heating?
Low refrigerant, a compressor issue, flow problems or settings.
Can pool chemicals damage the heat pump?
Unbalanced water chemistry can scale or corrode the heat exchanger.
Is it worth repairing an old pool heat pump?
We price repair and replacement so you can compare.
Which pool heat pump brands do you repair?
All major brands, including Hayward, Pentair and Rheem.
