Common signs

Signs your pool heater needs repair

A heater won't fire unless enough water moves through it, so a restriction elsewhere looks exactly like a broken heater. Here are some symptoms that help you tell which.

The heater won't turn on

Every heater has a flow switch that won't let it fire unless enough water is moving, so a dirty filter can stop a perfectly good heater. We check the power and the controls too.

The water isn't getting warm

We check the water flow and the filter, review the settings and the heater itself, and look at the power and controls as well.

The heater shows an error

The code narrows things down, but it reports a symptom rather than a cause, so we still check the system around it.

The heater starts then shuts down

A heater that lights and then quits is doing what its safety switches are built to do, so the visit looks at what tripped them.

Before you book a pool heater repair

With the right equipment, you can rule out two of these, no visit needed.

What to check, and where to stop

Clean or backwash the filter and check the pump basket, because a heater that isn't getting enough water through it will shut itself off every time. Then check that the heater is set above the current water temperature, which sounds obvious and is a real service call more often than you'd think.

Past that, stop. A gas heater involves a gas line and a sealed combustion chamber, and an electric one a high-amperage circuit next to water. Both are jobs for someone licensed, and getting us out is the quickest way to a warm pool.

Repair diagnosis

Pool heater repair starts with a $149 diagnostic

The technician who comes out is licensed and insured. They find what's actually wrong with your heater and put the repair price in writing before anybody orders a part.

You pay $74.50 when you schedule. Approve the repair and that $74.50 comes straight off your bill, so the diagnostic costs you nothing.

The question most people are really asking is whether this is a repair or a replacement. Plenty of heater faults are small and worth fixing: igniters, sensors, control boards, a pressure switch.

When a repair stops making sense

Some are not. When the problem is the heat exchanger on a gas heater or the compressor on a heat pump, the part can cost most of what a new unit costs.

We'll tell you that plainly rather than selling you a repair that doesn't make sense.

Which kind of heater you own

Which kind of heater you own changes that math, and you don't need to know which one you have before you book. Gas warms fastest; a heat pump moves heat out of the air instead of making it, so a cold snap cuts what it can do. If you can read the model off the label, tell us, and if you can't we'll work it out when we're there.

Repair Diagnostic
$149
  • Visible equipment review
  • Symptom review
  • Relevant pressure, flow, power, control, or equipment clues
  • Plain-language findings
  • Repair path or next-step recommendation
  • Repair estimate when parts or additional labor are needed

Any parts, labor, new equipment, cleaning or chemical work beyond the diagnostic get their own quote, done in-house so you're never waiting on a subcontractor.

What happens after the visit

You'll get a written quote covering what we found and what the repair costs. Approve it and pay the deposit inside the quote once your questions are answered.

And after you approve it

Once the deposit lands we order the parts and book the work. You'll get a link to choose your day, and a text as each stage moves.

The balance is due once the heater's running and you're satisfied with it, not before. We're reachable by text throughout.

If it's a simple fix

A heater fault can come down to a single part: a flow switch, an igniter, a sensor. We'll tell you which one, and what it takes to put it right. Plenty of calls end here.

If the heater is past saving

An older unit can reach the point where the repair bill outruns what's left to give. When that's where we land, we'll say so plainly, then talk through your options.

Either way the number reaches you in writing after the visit, and the heater stays as it is until you say otherwise.

Putting a new heater in

If that's where we land, you'll see the replacement priced just like you would for a repair. The $74.50 you put down still comes off the work, and you won't be starting over with a new company or explaining your pool to anybody twice.

We handle the whole changeover: disconnecting the old heater, running the plumbing, the electrical, and the gas or heat pump lines to the new one, and hauling the old unit away. Pentair, Jandy, Hayward and Raypak are pool heater brands we work on all the time, so your heater is in good hands.

Before we call the job done, we start the heater up and run a full systems check on it. If it ties into your automation, we'll make sure it's programmable. And we'll get you the receipt you need to register it, because the manufacturer's warranty doesn't start until somebody does. Anything you think of later, just text us.

Common questions

Pool heater repair FAQs

My heater won't turn on or ignite. What's wrong?
Could be the igniter, the gas valve, a pressure switch, or something simple like a tripped breaker. Share any error message when you schedule or text us a photo, and we'll check it and tell you plainly what it is.
Could my heater still be under warranty?
It might be, and it's worth a look before you schedule us out. The quickest way to find out is a call to the manufacturer with the model number and serial number off the label. Where the heater came from matters too. Most manufacturers give their best terms when the equipment is bought through an authorized distributor and fitted by a licensed technician. That's how we buy and how we work, and it can mean two to three years covering parts and labor. The same model from an online store might only carry about six months, parts only. It varies by manufacturer and by unit, so it's worth checking yours. And whatever you end up with, register the equipment after it's installed, because the coverage isn't automatic. If you need help, text us at (737) 259-7379 and we'll help you work out where you stand.
How much does pool heater repair cost?
Finding out is $149, and that comes back to you if you go ahead with the repair. What the fix runs depends on the part that needs repair or replacement, and a heat exchanger and an igniter are nowhere near each other. We work out which one you're looking at and put the price in writing before anyone orders anything.
Could a dirty filter be why the heater won't turn on?
It can be. Every heater has a flow switch that won't let it fire unless enough water is moving, and a dirty filter restricts that flow. If your filter is reading higher than its usual clean pressure, that's worth checking before anything else. It's a lot cheaper to rule out than a heater repair.
Do you install or replace pool heaters?
Yes, both. We install brand-new gas, electric and heat pump heaters, including on pools that have never had one, and we size the unit to the pool.
Do you service gas, electric, heat pump and solar heaters?
Yes. All four kinds turn up on pools around here, and each fails differently, so what we look at depends on your symptom and which type of pool heater you own. Tell us which kind you have when you schedule so we come prepared.
What isn't covered by heater repair?
Gas line installation and gas plumbing need the appropriate tradesman, so that part isn't ours. While a visual inspection of the heater is part of routine cleaning, heater repair work isn't.
What areas do you serve for pool heater repair?
Heater work takes us across Williamson and Travis Counties, with Lakeway and Leander at the far end of the run. The locations page lists the towns. Wondering about your street? Send your ZIP to (737) 259-7379.
