Customers say: Quality work

"I used several pool companies in the Cornelius area and was not satisfied with their customer service and quality of work. Matt successfully diagnosed and repaired some issues we were having with our pool equipment that the other companies could not. Matt's level of service and care for our pool is phenomenal. I highly recommend Escape Pool Cleaning!"

"My electrician was TJ and he did an amazing job. First up was installing a new heavy chandelier in the dining room. He determined the junction box wouldn't hold the weight of the new chandelier and installed one that would. Chandelier install went great. He moved forward to installing electrical two wall sconces in the dining room. Going into this project I was fulling expecting the whole wall to require drywall repair. In the end, I have one small, very neat, hole in the kitchen that will need repair. The chandelier had two single wall switches in the dining room. He placed a dimmer on one switch and on the second he changed it out to two switches. One for the chandelier and one for the two wall sconces. This exceeded my expectations for the room. He wrapped up the day by installing a new bar light fixture of the vanity. TJ is a thoughtful and talented electrician. I'm more than pleased with the work performed and would recommend Fairway Electric."

"OMG!! Where have these guys been hiding! I called several other companies because my pool was continuously losing water but none of them could seem to find the source. Within about an hour these gentlemen concluded that I had a main drain leak. They repaired the leak the next day and also took over the pool maintenance service. (They even pressure washed my deck!!) My pool has never looked nor functioned better. I would highly recommend the professionalism and knowledge of these men to anyone!"

FAQs for swimming pool heaters repair or service projects in Mooresville, NC

Replacing a pool heater costs $3,000 on average. Final pricing depends on the type of heater (gas, electric, or solar) and your pool's size. Factor for swimming pool repair costs, at an average of $3,800. When you start experiencing issues with your pool heater, other equipment and structural failures often follow. Installation is often the least expensive for electric and gas heaters. Heat pumps and solar panels often cost several thousand dollars more to install.

A pool heater’s lifespan is determined by its type and proper upkeep. Solar heaters last 20 to 25 years, electric heat pumps perform for five to 10 years, and gas heaters remain effective for 5 years. Regular pool maintenance safeguards performance and prevents premature failure. Ensuring that you adhere to a strict annual service schedule protects your investment and maintains consistent heating efficiency.

Depending on the size of your pool, location, climate, and current energy prices, you’ll spend up to $20 per hour to heat a pool using propane, $9 per hour using natural gas, and $1 to $2 per hour for a heat pump. Northern climates require more energy and can double the price. Standard estimates allow homeowners to easily estimate the cost of heating a pool for a month. Propane heaters, for example, are known to burn around 1 gallon per hour per 100,000 BTUs.

An electric or gas heat pump will take eight to 14 hours to heat a pool, while a solar heat pump takes 24 to 72 hours. Multiply the number of gallons by 8.34 to get your total pounds of water. Divide this figure by your heater's BTU rating to determine how many hours it takes to raise the water temperature by 1 degree Fahrenheit.

If your pool heater is not raising the water temperature to the desired level, the issue is caused by cold ambient conditions rather than a malfunction. The best solution is to install a solar cover that locks in heat and boosts efficiency. A solar cover costing $120 to $250 enhances heat retention, ensuring your heater performs at its peak. Additionally, verify that all settings—such as thermostat calibration and water circulation—are properly adjusted to support optimal heating.

Regular annual maintenance is crucial to keep your pool heater running efficiently and to avoid high repair costs. Investing $100 to $200 in yearly maintenance prevents issues such as excessive noise, surging energy bills, and malfunctioning controls. This proactive care not only prolongs your heater’s lifespan but also ensures reliable performance throughout the season. Always refer to your warranty guidelines to follow the required maintenance procedures.
