"As a new swimming pool owner that has no knowledge of swimming pool at all, I was looking for a contractor to adjust the depth of the existing swimming pool and replace the pool liner. I compared quotes from different companies and decided to choose Sweeney's after I spoke the owner Kenny, even though his quote is higher than other companies, his team has helped me understand the basics of swimming pool and take care of the entire life cycle of pool maintenace. Sweeney's Pool company has provided excellent service from adjusting depth of pool, new liner installation, pool opening, cleaning, closing and winter watch service at reasonable price. Sweenye's Pool company is honest, reliable and customer friendly. They have totally transformed the old swimming pool to a 5-star swimming pool every age can enjoy."

"Words can not express how grateful I am for Angel and Tiegre who fixed my in-ground pool. I recently purchased a home that had an inground pool and being my first pool, had a lot to learn. I had a major leak and after consulting with 4 different pool companies, I knew after speaking w Angel that he was the guy He is so knowledgeable, speaks the TRUTH and when he says he will do something or be there - he is. Honest, respectful around my wife and children and taught me so much during the replacement of all plumbing and pool liner 11 stars . Call Angel and team snd you will not be disappointed in your choice"

"My pool pump broke right after my pool was opened and the guy that opened my pool was not helpful at all. After calling around to other companies recommended by friends and not getting any calls back, I tried home advisor and found this company and decided to give them a shot. Right after putting in my request, David called me and was able to come a day later to help. He was so very nice and extremely knowledgeable about pools. He was able to fix the problem the next day and give us valuable advice about taking care of our pool. We are now going to use him to open and close the pool. I would highly recommend David and his company."

FAQs for swimming pool heaters installation and replacement projects in Deer Park, NY

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.
