"Our pool is 35+ years old. Watermark Pool Services updated our pool with new tile, new coping and new plaster about 10 years ago. This year, we needed a few repairs, plus my husband always wanted sky blue plaster. This company's work crews are knowledgeable, efficient and courteous. I wouldn't want any other company but Watermark doing the work on my pool! We absolutely love our "new" pool and the blue plaster looks amazing!"

"Hands down System Pools is the BEST pool service in the area! In the past 7 years we have used three other pool service companies with System Pools being the 4th. Their price is very reasonable considering the high level of customer service they give and the great job they do on keeping our pool crystal clear. For years we had to top off the water in our pool every other week. We were told it was because the water evaporated. Nick came in and immediately told us that a crack in our skimmer needed to be replaced which was done in 24-hours. Since then we have not had top off our pool, not once. The new skimmer saved us hundreds on our water bill! My advice- don't use those big pool companies who really don't want to provide pool maintenance, but want to charge you big money on repair jobs. Use System Pools they will take great care of your pool!"

"This is the second time that Dig M Pools did and installation for us. Again we were very happy with the job they did. We purchased our pool from them and it is a well made product. The owners wife was very helpful when we were deciding what pool to purchase. I would recommend Dig M Pools as first choice. Excellent job. Thanks Dig M."

"Because the technician said that the particular suction motor that failed on our spa was not a requirement, but a manufacturer's perk that only this one spa manufacturer provides, we save a lot of money by not repairing the motor.  The spa works perfectly.

"Great service, reliable, followed up with me the next day!!! Only because the technician was 2 hours late, I deducted a 1/2 star. Luckily, I work from home mostly - so my schedule is flexible. However, I know this may not be the case for everyone. I definitely WILL hire them again...:-)"

FAQs for swimming pool heaters repair or service projects in Potomac, MD

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.
