Pool Equipment Repair FAQ

It depends entirely on the component and whether it can be repaired or needs replacing. A pump repair like a new motor capacitor, seal, or impeller often falls in the low-to-mid hundreds, while a full pump replacement runs roughly $500 to $1,500 installed. Filter repairs are usually a few hundred dollars, a new salt cell runs about $300 to $900, and heater repairs range widely from a simple igniter to a major heat-exchanger job. Because Houston pools run hard through long, hot swim seasons, our partners diagnose the actual failure first and give you an upfront, itemized price — repair or replace — before any work begins, with no guessing over the phone.

There are several common culprits. If the pump is completely dead, it is often a tripped breaker or GFCI, a failed start capacitor, a bad motor, or a fried control board or timer. If it hums but will not spin, the capacitor or a seized bearing is the usual suspect. If it runs but moves little water, you are likely dealing with a clogged impeller, an air leak on the suction side, or a worn mechanical seal. Houston heat is especially hard on pump motors, so a pump that keeps overheating and shutting off may be on its way out. A technician can test the electrical components and tell you quickly whether it is a simple repair or time for a replacement.

A good rule of thumb: if the equipment is under about 8 to 10 years old and the repair costs less than roughly a third of a replacement, repairing usually makes sense. Beyond that, replacement is often the smarter long-term move — especially for pumps and heaters that have been run hard through Houston summers. Older single-speed pumps are a special case: even if yours still runs, upgrading to a variable-speed model frequently pays for itself in energy savings and is now required by federal efficiency standards for most new installs. Our partners will lay out the repair cost, the replacement cost, and the expected energy savings so you can decide with real numbers instead of a sales pitch.

A salt chlorine generator cell typically lasts about 3 to 7 years, with most Houston pools landing in the 4 to 5 year range because the system runs so many months of the year. Cells are largely a wear item — the coated titanium plates gradually stop producing chlorine and eventually cannot be revived. You can extend a cell's life by keeping salt and calcium levels in range and cleaning off scale, but a cell that is throwing "inspect cell" or low-output warnings after years of service usually needs replacing, not repairing. A new cell runs about $300 to $900 depending on the brand and pool size. The good news is the control box usually keeps working, so you are typically only replacing the cell itself.

For gas heaters, the most common causes are a dirty or failed igniter, a tripped high-limit or pressure switch, low water flow, a clogged burner, or a corroded heat exchanger. Many heaters also refuse to fire if the filter is dirty or a valve is throttling flow, because a safety switch senses low pressure and shuts the burner down. For electric heat pumps, weak or no heating often points to low refrigerant, a bad compressor or fan motor, or a frozen coil. Houston's humidity and coastal air also accelerate corrosion inside heaters, so an older unit throwing error codes may have heat-exchanger damage. A technician can read the fault code, check flow and gas pressure, and tell you whether it is a quick fix or a replacement.

In Houston's heat, a pool can lose a quarter to half an inch a day to evaporation alone, so some drop is normal — especially in summer. The classic test is the bucket test: fill a bucket with pool water, set it on a step so the water lines match inside and out, and check after a day or two. If the pool has dropped noticeably more than the bucket, you likely have a real leak. Other tell-tale signs of an equipment or plumbing leak include wet spots or erosion around the equipment pad, air bubbles from the returns, a spike in your water bill, or the pump losing prime. Our partners can pressure-test the plumbing and inspect the equipment pad to pinpoint whether it is a fitting, valve, or underground line — before you keep pouring water and chemicals into the ground.

For most Houston pools, yes — the payback is one of the best upgrades you can make. Single-speed pumps run at full power the entire time they operate, and because our pools run long hours through a long swim season, that adds up to one of the biggest electricity draws in the house. A variable-speed pump lets you filter at a low, efficient speed most of the day and only ramp up when needed, commonly cutting pump energy use by 50 to 80 percent. Many Houston homeowners see the difference on their bill quickly, and the pumps run much quieter. Federal efficiency rules now effectively require variable-speed on most replacements anyway, so if your old single-speed pump fails, upgrading rather than repairing is usually the smart call.

Our partners repair and replace all the major pool equipment brands you will find on Houston pools, including Pentair, Hayward, Jandy (Zodiac), Sta-Rite, Raypak, and others across pumps, filters, heaters, salt systems, and automation. That means you do not have to track down the original installer or a single brand's dealer to get a repair. Whether you have a Pentair IntelliFlo pump, a Hayward salt system, a Jandy automation panel, or a Raypak heater, they can source the right parts and make the repair — or recommend a properly matched replacement if the unit is beyond saving.
