When a piece of pool equipment fails, you'll usually hear two options: repair it, or replace it. Neither answer is always right. These are the questions that decide it, with published national cost ranges so you can sanity-check a quote.
Four questions that decide it
- What failed? A part (capacitor, seal, igniter, sensor, O-ring) or the core of the unit (motor, heat exchanger, tank)?
- How old is it? Equipment near the end of its typical life tends to fail again soon after a repair.
- What does the repair cost against replacing? A common rule of thumb: when a repair approaches half the cost of a new unit on older equipment, replacement usually wins.
- Is something better available? For pumps in California, the replacement will generally be variable-speed, which can lower running costs.
Pool pumps
| Usually repair | Usually replace |
|---|---|
| Failed start capacitor | Burned-out motor on an older single-speed pump |
| Leaking shaft seal (caught early) | Cracked pump housing or wet end |
| Noisy bearings on a newer motor | Repeated failures in the same season |
| Clogged impeller, bad lid O-ring | Pump badly undersized or oversized for the system |
Angi's 2026 figures put most pump repairs at about $100–$700 and a full replacement at about $1,300 on average. California's rule for replacement motors is explained in California pool pump law. More on pumps: pool pump repair.
Pool heaters and heat pumps
| Usually repair | Usually replace |
|---|---|
| Igniter, flame sensor, or pressure switch | Cracked or badly corroded heat exchanger |
| Control board on a mid-life heater | Heater near or past typical life with a major failure |
| Rodent damage to wiring | Repeated expensive repairs |
| Heat pump fan or sensor | Heat pump refrigerant system failure on an older unit |
Angi puts pool heater repairs at roughly $166–$799; HomeGuide puts replacement at about $1,600–$5,200 installed, with a typical life of 10–12 years (shorter for gas heaters). See pool heater repair.
Filters
Filters are usually repairable: new cartridges, DE grids, sand, O-rings, or a multiport gasket. A cracked tank or a filter that's undersized for the pool is the usual reason to replace. HomeGuide puts new filters at about $250–$1,700 installed. See pool filter repair.
When the whole pad is the same age
In East County neighborhoods where the original equipment went in at the same time, one failure often signals the next. Ask for a quote on the failed part plus a short condition report on the rest, so you can choose between fixing one thing now or upgrading the pad in one visit. See pool equipment repair.
Frequently asked questions
Can a pool pump be repaired?
Often. Capacitors, seals, bearings, impellers, and O-rings are common repairs. A burned-out motor on an older single-speed pump is usually replaced, and in California the replacement will generally be variable-speed.
Can a pool heater be repaired?
Usually, if the problem is a part like an igniter, sensor, or switch. A failed heat exchanger on an older heater usually means replacement.
How long does pool equipment last?
It varies with use, chemistry, and climate. HomeGuide puts pool heaters at about 10–12 years on average. Pumps and filters vary widely by type and maintenance.
