It’s Time To Experience the Pool Duck Difference
A pool heater extends your swim season and makes your pool comfortable year-round. When it stops working, it can be frustrating, especially because heater issues are often misdiagnosed, leading to unnecessary part replacements or technician call-backs. Pool Duck takes a thorough diagnostic approach to heater repair so we fix the actual problem, not just the symptoms.
Our technicians work on all major heater brands and types, from gas-fired units to electric heat pumps. We assess, diagnose, and repair with the precision your equipment deserves.
The majority of premature pool heater failures are caused by one thing: poor water chemistry. Low pH creates acidic water that corrodes heat exchanger tubes from the inside. High calcium and alkalinity cause scale that insulates the exchanger and forces the unit to work harder. Our weekly service maintains the chemistry ranges that protect your heater, and our repair technicians will flag any signs of chemistry-related damage during every service visit.
Pool Duck provides professional, full-service pool care designed to keep your pool clean, balanced, and running efficiently week after week.

A pool heater extends your enjoyment of your pool throughout the year and in Florida’s shoulder seasons, it is what keeps your pool genuinely comfortable when morning temperatures drop and evening swims become a question of whether the water is warm enough. When your heater stops working correctly, whether it fails to ignite, cycles on and off without reaching temperature, or displays an error code you cannot interpret, the problem needs professional attention from someone who understands pool heating systems in depth.
Pool Duck’s repair technicians are experienced with all types of residential pool heaters, including natural gas, propane, and electric heat pump systems. We approach heater repair the way we approach all equipment service: with a thorough diagnostic assessment before any repair recommendation, clear explanation of what we find, and transparent pricing before any work is authorized. Heater problems are not always what they appear to be at first look, and accurate diagnosis saves our customers significant time and money compared to trial-and-error part replacement.
Gas pool heaters, whether natural gas or propane, operate by burning fuel in a combustion chamber and passing pool water through a heat exchanger that absorbs the combustion heat before returning the warmed water to the pool. The heating process is controlled by a series of safety and operational components including a pressure switch that verifies adequate water flow before allowing ignition, a high-limit switch that shuts the heater down if water temperature exceeds a safe threshold, a thermistor that measures the water temperature and signals the control board when heating is needed, and an ignition system that initiates combustion. When any of these components fails or falls out of calibration, the heater either refuses to operate or operates incorrectly.
Heat pump pool heaters operate on a fundamentally different principle. Rather than generating heat by burning fuel, a heat pump extracts thermal energy from the ambient air and transfers it to the pool water using a refrigerant cycle similar to a reverse air conditioner. A fan draws outdoor air across an evaporator coil, the refrigerant absorbs heat from the air, the compressor increases the refrigerant pressure and temperature, and the heated refrigerant passes through a heat exchanger that warms the pool water. Heat pumps are significantly more energy efficient than gas heaters for continuous operation but heat the water more slowly and lose effectiveness when ambient temperatures drop below about 50 degrees Fahrenheit.
The single most common cause of premature pool heater failure is not a mechanical defect or an electrical problem. It is poor water chemistry. This point deserves emphasis because it is both the most preventable cause of heater damage and the most frequently overlooked by pool owners who are managing their own chemistry or working with inconsistent service providers.
Low pH creates acidic water that is corrosive to copper and other metals. Pool water that circulates through a heater with chronically low pH will slowly attack the inside of the heat exchanger, thinning the copper tubing until it develops pinhole leaks or cracks. This type of damage is typically not covered under manufacturer warranty because it results from improper water maintenance rather than a product defect. Heat exchangers destroyed by acidic water must be replaced, which is one of the more significant repair expenses in residential pool equipment.
High pH combined with high calcium hardness creates the opposite problem: scale. Calcium carbonate precipitates out of the water and deposits inside the heat exchanger tubes, forming a layer of mineral buildup that acts as insulation. As scale accumulates, the heater must work harder and longer to achieve the same temperature rise, energy efficiency drops, and the heat exchanger is subjected to higher operating temperatures that accelerate wear. Significant scale buildup requires professional descaling treatment to restore the exchanger to function, and severe cases require heat exchanger replacement.
Pool Duck’s weekly service maintains the water chemistry parameters that protect your heater. When our technicians perform a heater repair, we always review the water chemistry history and address any ongoing chemistry issues that contributed to the failure, so the same problem does not develop in the replacement component.
Pool heaters have a typical service life of eight to fifteen years depending on type, usage, and how well the water chemistry has been maintained. Gas heaters at the lower end of this range that require a heat exchanger replacement are often better candidates for full unit replacement, particularly when more efficient current-generation models offer substantially better performance than the unit being repaired. Pool Duck provides honest guidance on this decision every time it is relevant, including a clear cost comparison between repair and replacement so you can make an informed choice.
Pool heater technicians occasionally encounter heaters that fail to ignite or that run inconsistently not because of any heater component failure but because of a problem with the gas supply itself. Low gas pressure at the heater can result from an undersized gas line that cannot deliver adequate flow for the heater’s BTU demand, a regulator that has failed or is set incorrectly, or a supply issue at the meter level. When multiple gas appliances in the home are running simultaneously and the gas line was sized for a lower total load than is currently being drawn, the heater may receive insufficient pressure to fire correctly. Pool Duck’s heater diagnostic process includes checking manifold gas pressure with a manometer to confirm that the gas supply to the heater is within the manufacturer’s specified range, allowing us to distinguish between a heater component failure and a supply infrastructure issue before recommending any parts.
