Maintenance costs
Both sources put annual pool heater maintenance at $100 to $200.[1][2] HomeAdvisor’s summary bullet lists $150 to $200 while its body text says $100 to $200; the body figure is used here. Both also note that a solar cover at $120 to $250 can help when a heater seems to underperform in cold ambient conditions.[1][2]
Repair or replace the heater
The siblings diverge on replacement cost: Angi puts a new pool heater at $2,800 on average, while HomeAdvisor puts replacement at $3,000 on average; both versions are reported as published.[1][2] HomeAdvisor adds that most pool heater warranties range from one to 12 years, and that heaters out of warranty usually mean paying the full repair cost.[2]
DIY or hire a pro
Angi limits DIY to basic troubleshooting and upkeep: checking that valves are open, cleaning the filter, checking electrical connections and the breaker, clearing debris around a heat pump’s coil, and replacing the cartridge filter. It says refrigerant issues, electrical work and gas connections belong to professionals, and warns that DIY mistakes can void warranties or break the heater beyond repair.[1] For the solar cover both sources recommend as a low-cost efficiency fix, the Solar Pool Covers category at Home Depot carries covers by pool size (non-affiliate link, provided for convenience).
