"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!"

"If you're looking for an honest electrical company, look no more. Larry is completely honest and I can't recommend him high enough. He had a prime opportunity to not only charge me for a service call but to charge for parts and labor on a very simple fix. He walked me through it over the phone when other electrical companies were more than happy to come to my home and charge me for the service call and God only knows what else. Thanks Larry! You're the best!"

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

"Let me start off by saying, we have had some very bad experiences with swimming pool companies, however, the experiences we've had with this company have been nothing but positive!  
Glenn has always been prompt at responding to my calls and inquiries, always replying within 24 hours.  He has been honest and forthcoming with information.  He has called in experts to back him up when needed and his prices are very reasonable.

FAQs for swimming pool heaters repair or service projects in Unionville, 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.
