"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!"

"I have been impressed with Subcomm Pools since our first contact. After days of research trying to find a company that could help us with a potential leak, I decided to contact Subcomm Pools. What really distinguished them from all the other companies was their willingness to put their weekly service package prices on their website. As a fairly new pool owner, I had quickly noticed that most companies instead advertise that customers need to call for a quote or estimates. Even though I wasn?t currently looking to purchase routine services, I appreciated this direct and transparent approach.
After I called and explained our problem to the Service Manager, Hristo, he gave me step-by-step instructions to follow so that I could narrow down the source of the leak myself without having to pay to send out a technician to do it. This really ended up saving us money because as it turned out, we did not have a leak.
As a result of the positive, professional and courteous experience I had with Subcomm Pools up to this point, I decided to purchase their bi-weekly pool services. The teams they have sent out to service our pool have been no less impressive. They are all very competent, courteous, and always willing to answer any questions I have.
I highly recommend Subcomm Pools?they truly demonstrate that they value great customer service.

"BJ Pool & SPA is a first rate company.  Bob, the owner, has been working with pools for decades and knows everything about pools. He is actually willing to try to repair equipment, unlike many other lesser companies that merely put in new stuff.  If you have any issues with your pool and spa, these are the people to call: they will fix anything and will always provide you with the best options.  Bill, the specialist who came to work on the unusual configuration of equipment for my small indoor pool and spa, demonstrated a great deal of experience, ability and honesty.  BJ Pool & Spa might not seem cheap, however, given their vast knowledge, experience and technical ability, they will provide you with quality service and advice that will save you money in the long run.  Their competence and integrity is extremely reassuring.  It isn't always easy to find a good pool company (this industry isn't as regulated as other professions), and it took me a while to find this one. BJ Pool will be the company I call when I want honest and reliable service

"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...:-)"

"The GPro team were so meticulous! They measured really carefully and the result is a walkway that is not only beautiful, it drains water away from my house. I won’t have any more puddles or ice patches to contend with. They were also really careful to preserve the plants I wanted to keep, so now I have a lovely walkway and my garden is still intact, too. I’m really pleased with their work."

"My pond is the healthiest it's ever been, I don't know if it's because of backyard ponds, or whatever? But I now have baby fish about 12 of them and I am going to hire them to do my winterization. I got a very professional reminder from backyard ponds in the mail today, and I really appreciate the reminder. Sometimes things like this slip your mind, but it's very nice that they remind you that winter is coming up, and you need to plan for the future. My fish are not expensive, because this is a newly renovated pond. But I'm very happy with the job that they did, and I will recommend them in the future. And I will be using them very soon"

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