Pool Heat Pump Repair
A pool that won’t hold temperature is a pool nobody swims in. We diagnose and repair all major heat pump brands so you get your season back.


What Service Is
Same Refrigeration Principles, Different Application
A pool heat pump works like your air conditioner in reverse — it pulls heat from the outside air and moves it into your pool water. Compressor, refrigerant circuit, coil, controls: it’s the same system we work on every day, plumbed to water instead of ductwork.
That matters because a lot of pool companies aren’t HVAC companies. We diagnose the refrigeration side properly rather than swapping parts until something changes, and we service residential and commercial units across Pinellas County.
Common Problems We Fix
Common Pool Heat Pump Problems
Not Reaching Temperature
The unit runs but the water stays cool. Low refrigerant, a dirty evaporator, or restricted water flow are the usual suspects — and each needs a different fix.
Won’t Start at All
Control board failures, capacitors, and flow switches are common culprits. Many are affordable repairs once the actual fault is identified.
Water Leaking From the Unit
Some condensate is normal on a humid day. A steady leak is not — it may be the heat exchanger, and running it that way risks far bigger damage.
Grinding or Rattling Noise
Fan motor bearings, a loose fan blade, or compressor trouble. Mechanical noise is worth diagnosing quickly before it takes the compressor with it.
Short Cycling or Error Codes
A unit that switches off repeatedly or throws codes is protecting itself from something. The code narrows it down; proper testing confirms it.
Rising Run Times
If it takes noticeably longer to heat than it used to, efficiency is dropping — often a fouled coil or a slow refrigerant loss you can still catch cheaply.
Our Process
How a Pool Heat Pump Repair Works
Tell Us the Symptoms
What it’s doing, any error codes on the display, and roughly how old the unit is. That usually tells us what parts to bring.
Full System Diagnostic
We check the refrigerant circuit, electrical components, water flow, and the heat exchanger — not just whatever threw the code.
Findings and Pricing
You get a clear explanation of what failed and a price before work starts. On an older unit where a repair doesn’t pencil out, we’ll say that too.
The Repair
Common failures are handled on the visit. Anything needing a brand-specific part gets ordered and scheduled with a clear timeline.
Verify It’s Heating
We confirm the unit is running to spec and actually raising water temperature before we call it done.
Why Choose Us
Why Carr for Pool Heat Pump Repairs
A pool heat pump is a refrigeration system. We’ve spent decades on compressors, refrigerant circuits, and controls — that’s the same skill set, applied to water.

Hayward, Pentair, AquaCal and others. Whatever’s on your pad, we can diagnose it and source parts for it.

A control board or a fan motor is a repair, not a reason to sell you a new unit. We quote the fix, and we’re upfront when a unit genuinely isn’t worth repairing.

A heat pump down in the cool months is a pool you can’t use. We schedule promptly rather than leaving you waiting through the part of the year you bought it for.

Salt air and year-round runtime are hard on poolside equipment. We’ve been maintaining it in Pinellas County long enough to know how these units age here.

Frequently Asked Questions
Pool Heat Pump Questions We Hear Often
It captures heat from the outside air and transfers it into your pool water using a refrigerant circuit — essentially an air conditioner running in reverse. That’s why it’s efficient, and also why it slows down when air temperatures drop.
Common causes are low refrigerant from a leak, a dirty evaporator coil, restricted water flow through the unit, or a failing compressor. Start by checking that the filter is clean and water is circulating properly — if it is, the refrigeration side needs testing.
For most Florida pools, holding a steady set temperature costs less than repeatedly heating from cold, because reheating a cooled pool takes many hours. A cover makes a bigger difference than almost anything else, since most heat loss is from the surface.
Ten years or more with regular service, though coastal salt exposure shortens that for units near the water. Keeping the coil clean and clear of landscaping is the single easiest thing an owner can do to extend its life.
