"Water Mark Pools did an amazing job replacing our pool tile, regrouting, and recoating the pool to ensure there were no cracks or grout issues. The entire crew showed up every day, worked hard, and paid close attention to every detail. The quality of the workmanship was truly top notch, and the finished product looks absolutely fantastic. Customer service was exceptional from start to finish. Nick provided first-class service, he came out personally, explained the entire process clearly, gave us a fair price, and handled everything professionally. He also followed up with the company to coordinate filling the pool with water, which made the whole process seamless and stress-free. It’s hard to find companies this reliable, efficient, and professional anymore. I highly recommend Water Mark Pools to anyone looking for high-quality pool work! Patti Miller Chesapeake Beach MD"

"My furnace is very old and quit working.  I called several HVAC companies and received  quotes to replace ranging from $1,800 to $11,000.  I found Energy Wise on Angies and called Matt.  He returned my call within 30 minutes and was at my house within 24 hours.  After his inspection, he stated that the furnace was still in good shape and could offer me a  number of years service before buying a new unit.  He suggested replacing the motor and fan and cleaning internal parts.  All of this was completed by the end of the next day.
Matt is very professional, punctual, courteous and a pleasure to deal with.  Not only did he save me a great deal of money, I now have a heating/air conditioning system that has never worked better.

"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

"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.

"I bought a deal from Walls Electrical in May 2014. It was $99 for $200 worth of electrical services. We could not figure out why our powder room lighting would not come on even after replacing bulbs, checking breakers, and resetting GFCIs. A Walls technician came out and figured out that the lights were controlled by a small transformer that was connected into an outlet in the adjoining closet. Somehow we had unplugged the transformer without realizing it. Problem solved. The technician then replaced the lighting fixture that my husband had taken apart while investigating the matter a few days prior. While he was replacing the fixture, I handed the technician a circular metal piece that belonged in the fixture. The technician adamantly said that the metal piece did not belong. I had my doubts, but I deferred to his judgement since he is the professional. Well, a day later, that fixture stopped working and when we investigated, we saw that the bulb had burned out the plastic part of the fixture, because the metal piece had not been replaced. 
I immediately called Walls to let them know what happened. At first, they were very prompt in responding to my complaint. I sent pictures, they said they were working on it. Then weeks passed and nothing happened. I called and was told that the person who was handling my account was having health issues and that someone else would get on it. Weeks passed again and nothing happened. I called and was told that my contact person wasn't with the company anymore and somehow I had fallen through the cracks. They were very apologetic. It wasn't until late Fall that a technician was sent out to rectify the situation. They had to replace all 3 lights in the powder room and the product they brought (the closest match they said they could find) and the way it was installed just didn't have the beautiful flush finish that my previous fixtures had. 
Needless to say, a very simple issue turned into a huge waste of my time and energy. I'm happy they finally rectified the situation, but it took way too long and the end product left a lot to be desired.

"Though hard to reach on short notice (always cleaning pools, it seems), calls were always returned and every effort was made to respond to realtor's concerns - including extra trips when weather or access were issues. Great service!"

"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."

FAQs for swimming pool heaters installation and replacement projects in Merrifield, VA

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.
