My pool needed pretty much a rework of all the filtering and pump equipment due to age.

Contacted several companies for quotes.  BJ's was in the middle ground pricewise, but 2 of the companies were also sky high on their estimates.

These guys removed all the old equipment, put in a new concrete pad, & installed all new equipment.

They started on schedule and finished when they said they would.

Bill from BJ's did a great job and is very professional as is everyone else there at BJs.

Bob (the owner of BJs) even found me a replacement for my outdated fiber optic light which had not worked in years and had been discontinued by the manufacturers for years as well. Talk about finding a needle in a haystack!

Thanks to all at BJs for the great job!

Great, Two technicians showed up and began work. I was called in to view the original builders work. Really! My builder did not even have an electrical box to feed the lights just a wire. I was told some drywall would be removed to feed the wires for the 2 lights. OK.. Well they cut the wall ran the wires set the boxes and replaced the piece of drywall with the scraps. I now have 2 perfectly centered and level locations for my lights. They even left me some drywall scarps from the holes they cut to fill the hammer holes the original builder left.

A great job from a great crew. My wife loved the  sound of the Vac when they cleaned up whatever mess they made. I never saw the mess. Great! Great! Great!

I/m looking for more electrical work just to have them back.....

"My pool couldnt even be called a pool at the time an estimate was provided. The previous owner of my home atempted to turn a liner pool into a concrete pool and use kitchen tiles along the wall. Needless to say the base of the pool cracked, broke and I could literally see dirt. The service manager at Subcomm pools communicated their concerns and the quoted price along with their plan of action. They communicated consistently and always kept me abreast of what was going on. They are very courteous and will go the extra mile to ensure I was satisfied. They took the time to answer any questions that I had. They also directed me to reading material that assisted with the maintenance of my pool. Very courteous staff and hard working. They were in the heat of the sun and still kept driving on. I would bring them a pitcher of water and ice everyday and they were very grateful."

"Called about leak Sunday morning. Plumber came out Monday, determined it needed replacement and notified Choice, who approved claim and permitted plumber to order new water heater. Thursday new water heater was installed. Was kept updated every day by both Choice and the plumber. Workers left my garage clean and I have hot water. Very satisfied and have recommended Choice Home Warranty on the Nextdoor app."

"The technician did an excellent job. It did take a while to get the repair finished, but that was due to Bertazzoni delivering the parts. I have had multiple problems with this particular appliance. My range now works better than it did when new, but I have a feeling that even if I have continuing problems with it, American Home Shield will just repair rather than replace due to the cost of the range. By the way, I'm not exactly sure of the date of the repair."

"The owner of this company serviced our pool for over 15 years.  He was extremely responsible and professional.  He always responded to my calls promptly and made whatever repairs were necessary as quickly as possible.  He was always sensitive to costs of replacement items.  He also spent the off season going to classes and manufacturer training to be current in the industry.  His rates were reasonable.   When we were remodeling our pool deck and pool, he coordinated with the pool and deck contractors.  When our heater needed servicing he was knowledgeable enough to conduct the service himself.  Our pool was always crystal clear.  If he hadn't cut back with servicing our area, I would still have his company service our pool. "

FAQs for swimming pool heaters installation and replacement projects in Washington, DC

Yes, you can add a heater to an existing pool. A pro can retrofit a heater to nearly any in-ground or above-ground pool. Adding a heater allows you to start the swim season earlier, finish it later, and maintain a steady water temperature in between. Many owners schedule the job during a larger pool upgrade, but it also works as a standalone project. Professional installation ties the new unit into the existing pump and plumbing for safe, efficient operation.

Most owners switch the heater on a day or two before they plan to swim, then shut it down afterward. Reaching the target temperature can take 24 to 72 hours, depending on pool size and outdoor conditions. Using a cover while the heater is off helps hold the heat and keeps energy costs in check.

Pool heaters can freeze if left exposed to extreme conditions. Freezing can damage internal heater components, potentially leading to costly pool repairs. Cycling water, covering the heater, and regular maintenance help prevent freezing. Sealing or winterizing your heater also protects it during the season—this involves draining water from the heater and its components.

Pool heaters operate with lifespans spanning from seven to 30 years. Gas and propane models last seven to 12 years, while electric and solar heaters perform efficiently for up to 30 years. Consistent professional maintenance and routine inspections extend the heater’s life and improve its performance, ensuring a safe and reliable heating system for your pool.

Before hiring a pool heater installation contractor, conduct thorough research by reviewing online feedback and gathering recommendations from trusted sources. Contact multiple professionals to discuss pricing, request references, and understand the complete installation process. This careful evaluation ensures you select a qualified contractor who delivers high-quality service and a successful installation.
