Introduction
Your pool heater stopped working right when you wanted to take that first swim of the season. Now you’re wondering: how much is this going to cost me? Pool heater repair costs in 2025 range from $150 for simple fixes to over $2,000 for major component replacements, with most homeowners paying between $300-800 for typical repairs.
The wide cost range depends on several factors: what type of heater you have, what’s actually broken, where you live, and whether it’s peak swimming season. Gas heater repairs typically cost $200-1,200, heat pump repairs run $300-1,800, and electric heater repairs are usually $150-600. Labor costs alone can range from $75-150 per hour, plus service call fees of $75-200.
Understanding repair costs helps you make smart decisions about whether to fix or replace your heater. Some repairs are no-brainers – a $200 thermostat replacement on a 5-year-old heater makes perfect sense. Others require more thought, like spending $1,400 on a heat exchanger for a 10-year-old gas heater when a new unit costs $2,800.
This guide breaks down actual 2025 repair costs by heater type and problem, explains what drives these costs, and helps you determine when repairs make financial sense. We’ll also cover ways to reduce costs and red flags that suggest it’s time to replace rather than repair.
How Much Does It Cost to Repair a Pool Heater?
Pool heater repair costs typically range from $150-$2,000, with most homeowners paying $300-$800 for common repairs in 2025. The total cost depends on what’s broken, your heater type, labor rates in your area, and when you need the work done.
