Pool Heater Repair in Clearwater, FL
The first night it drops below 60 degrees, which around here feels like parka weather, you switch on the heater, and nothing happens. Or it clicks, fires for a minute, and shuts off. Or the heat pump fan spins all afternoon, and the water is still cold.
Dog Days Pools diagnoses gas pool heaters and heat pumps, replaces the failed parts, and replaces the heater when it's done. We also check the things around the heater that stop it from working, because a heater needs steady water flow, and a dirty filter or a pump problem can shut it down just as surely as a bad part.
Call call(727) 205-0566 and tell us what the heater is doing, and any code on its display.
Why a pool heater won't heat
A heater is at the end of a chain: power or gas in, water flowing through, and a control telling it to run. When the water stays cold, the fault can be anywhere along that chain.

Not enough water flow
Heaters have safety switches that stop them from firing when the water isn't moving fast enough. A loaded filter, full baskets, a pump that's losing prime, or a valve set for the spa can all trip that switch, and the heater looks broken when it's protecting itself.

- check_circlePump flow and valve positions checked
- check_circlePressure or flow switch tested

A part in the heater has failed
On a gas heater: an igniter, a flame sensor, a high-limit switch, a control board, or a gas valve. On a heat pump: a fan motor, a sensor, or a control board. An error code on the display narrows it down, which is why we ask for it when you call. We don't do refrigerant work on heat pumps; if that's where the fault is, we'll tell you.

- check_circleFailed parts replaced when parts are still made
- check_circleHeat exchanger and burner tray checked on gas units

The settings, the schedule, or the season
A heater set for the spa, a timer that never calls for heat, or a thermostat turned down after a party. Heat pumps also slow down as the air gets colder, so on the coolest nights they struggle to keep up, even when nothing is wrong.

How a heater repair works
1. Tell us the symptom and the code
Won't fire, fires and quits, or runs without warming. A photo of the display and the heater's label helps.
2. We check the chain
Power or gas supply, water flow, the heater's safety switches, and its controls, in that order.
3. Repair or replace, with prices
You hear what failed and what fixing it costs. If the heater is old enough that repairs won't last, you'll hear what a replacement costs too.
4. The repair
The failed part is replaced, or the heater is replaced and connected.
5. Tested and warming
We run the heater, confirm it's warming the water, and set the pool or spa temperature where you want it.

Heater problems we fix

What heater repair doesn't include:
- remove_circleWe don't repair heaters on freestanding hot tubs. Spas attached to a pool are covered.
- remove_circleWe don't service heaters for commercial or above-ground pools.
How a heater repair is priced
The error code and the heater's age decide most of it, so Larry won't guess at a price before he's seen both. The cost comes down to:
The failed part:An igniter or sensor is a smaller job than a control board or heat exchanger.
Gas heater or heat pump:Different parts and different work.
The heater's age:Whether parts are still made for it, and whether a repair will last.
Replacement:The size and type of heater, and whether anything at the pad has to change to fit it.
Any repair over $50 is priced for you first; nothing is hidden, and heaters under a manufacturer warranty are handled under that warranty's terms. Weekly customers' small wear parts under $50 go on the next invoice; everyone else approves every repair.
