Pool Equipment Repair & Service in Charleston, SC
Your pool equipment runs nearly year round in the Charleston Lowcountry. When a pump locks up on a July afternoon or a heater quits in early March, every hour without a fix means algae growth, wasted chemicals, and a pool your family can’t use. The PoolCare Pros diagnoses and repairs pumps, heaters, filters, salt chlorine generators, and automation systems across Goose Creek, Charleston, Mount Pleasant, Summerville, and surrounding communities.

Signs Your Pool Equipment Needs Attention
Pool equipment rarely fails without warning. The key is knowing which signals mean a quick fix and which ones point to a bigger problem. If you notice any of the following, your system is asking for attention.
Grinding, screeching, or humming from the pump usually indicates worn bearings, a seized motor, or a jammed impeller. Weak return jets or no visible water movement points to a circulation blockage, suction leak, or failing motor. A pool heater that cycles on and off but never reaches temperature often has a clogged heat exchanger, faulty thermostat, or low water flow. Cloudy water despite balanced chemistry suggests your filter may have a cracked manifold, torn cartridge, or channeled sand bed. A salt cell reading “low salt” when levels test normal means the cell is scaling or the control board is misreading. A tripped breaker every time equipment turns on signals a short in the motor windings, corroded wiring, or overloaded circuit. Automation or smart controls losing connection or ignoring schedules could indicate a firmware issue, relay failure, or corroded sensor.
If any of these sound familiar, the problem will not fix itself. Waiting typically turns a manageable repair into a full equipment replacement.
Pool Pump Repair
The pump is the heart of your pool’s circulation system. It pulls water from the skimmer and main drain, pushes it through the filter, and distributes treated water back to the pool. When the pump fails, every other piece of equipment downstream (heater, chlorinator, automation) stops working too.
Common Pump Failures in the Charleston Lowcountry
Charleston’s climate creates a unique set of stressors for pool pumps. Salt air from the coast accelerates corrosion on motor housings and electrical connections, even on pools 20 miles inland. Summer humidity causes condensation inside motor compartments, degrading insulation and shortening motor life. And the sheer volume of live oak leaves, pollen, and palmetto debris clogs baskets and impellers more aggressively than in drier climates.
The most frequent pump repairs we perform in this area involve worn shaft seals (the leading cause of pump base leaks), failed capacitors that prevent motors from starting, corroded wiring terminals, and clogged or cracked impellers that reduce flow rate.
Repair or Replace Your Pool Pump
Not every pump issue requires a full replacement. Here is a practical framework we use with homeowners.
Repair generally makes sense when the pump is under five years old, the failure is a single component (seal, capacitor, O ring), the repair cost is well under half the price of a new unit, and the pump is properly sized for the pool.
Replacement generally makes sense when the pump is eight or more years old with recurring issues, the motor windings are burnt or corroded internally, the repair cost approaches half the price of a new unit, or the current pump is oversized (wasting energy) or undersized (starving flow).
If replacement is the better path, upgrading to a variable speed pump is worth considering. They use significantly less energy than single speed models, run quieter, and often reduce monthly electricity costs substantially over the life of the unit.
Pool Heater Repair
Charleston’s pool season stretches from April through October, and many homeowners heat through the cooler shoulder months to extend their use further. When a heater fails mid season, water temperatures drop fast and the pool becomes unusable within days.
Gas heaters. The most common failures are corroded heat exchangers (accelerated by Charleston’s salt air), clogged burner orifices from insects nesting during the off season, and ignition module failures. Gas heaters heat water quickly but tend to have shorter lifespans in coastal environments.
Electric heat pumps. These are more energy efficient but sensitive to ambient temperature and airflow. Dirty evaporator coils, refrigerant leaks, and failed fan motors are the top repair calls we see. They work best when nighttime temperatures stay above 50°F, which covers most of Charleston’s season.
Electric resistance heaters. Less common in residential pools, but when used, the main failure points are burnt heating elements and tripped high limit switches caused by low water flow.
We service all major brands including Pentair, Hayward, Jandy, and Raypak. Every heater diagnostic includes checking gas pressure or electrical input, inspecting the heat exchanger, verifying water flow rates, and testing safety switches before we recommend any repair.
Pool Filter, Salt System, and Automation Repair
Filters. We repair and service cartridge, DE (diatomaceous earth), and sand filters. Common issues include cracked manifolds in cartridge filters, torn grids in DE filters, and channeled or calcified sand beds. If your filter pressure runs 8 to 10 PSI above its clean baseline, it needs attention, whether that means cleaning, element replacement, or a full media change.
Salt chlorine generators. Salt cells typically last three to five years in Charleston’s climate. Calcium scaling from hard water and high usage shorten that lifespan. We inspect cells for scale buildup, test output with independent meters (not just what the control board reports), and clean or replace cells as needed. If your salt system is producing insufficient chlorine despite correct salt levels, the cell or the control board is usually the issue.
Pool automation. Systems like Pentair IntelliCenter, Hayward OmniLogic, and Jandy iAqualink let you control pumps, heaters, lights, and water features from your phone. When they malfunction, the problem can be a failed relay, a corroded sensor, a firmware bug, or a wiring issue at the equipment pad. We troubleshoot automation at the board level, not by guessing and swapping parts.
Why Charleston Pools Break Down Faster
Pool equipment in the Lowcountry faces environmental conditions that equipment in other regions simply doesn’t. Understanding these factors helps explain why your equipment may be failing sooner than expected.
Salt air corrosion. Even pools in Goose Creek, Summerville, and North Charleston, well inland from the coast, experience salt laden air that corrodes exposed metal on motors, heater cabinets, and electrical connections.
Extended operating season. Pools here run seven to nine months per year, compared to four to five months in northern states. That means your pump logs nearly double the operating hours annually.
Heat and humidity. Sustained temperatures above 90°F and humidity above 80% cause condensation inside motor housings and accelerate rubber seal degradation.
Heavy organic debris. Live oaks, pine pollen, Spanish moss fragments, and palmetto fronds create debris loads that clog baskets, impellers, and filter elements faster than pools in drier climates experience.
Hard water and mineral buildup. Many Lowcountry water sources carry higher calcium and mineral content, which scales heater exchangers and salt cells more aggressively.
These are not excuses for equipment to fail. They are reasons to work with a local team that understands them and can recommend the right preventive measures.
Why Choose The PoolCare Pros
The PoolCare Pros was founded by Darryl Jones, a Navy veteran and former residential contractor with over 15 years in the pool industry. Our team is CPO Certified (Certified Pool Operator), a member of the Pool & Hot Tub Alliance, and Leaktronics Certified for swimming pool leak detection.
That diagnostic background matters for equipment repair. Many pool equipment problems are misdiagnosed because the technician only looks at the component showing symptoms. A heater that won’t fire might have a perfectly good ignition module but an upstream pump that’s not delivering enough flow. A pump that’s overheating might have a correctly functioning motor but a clogged impeller starving the system. We test the full circuit, not just the obvious piece.
We treat every pool like it’s our own.
