"Need a pool company? This is the only one. Sweeney’s has been a lifesaver. We bought a home with this seemingly beautiful pool. Grateful for Kenny Sweeney and his incredible team. They have rebuilt the pool into a brand new beautiful pool. We inherited a hole in the ground and had no idea what was needed. Some companies said put in a liner, leave the liner, what was found beneath was a disaster! The pool needed a new liner, new piping, new electrical work, new sand foundation as well the new liner which is backed by foam. Watching this team come in to complete each facet of the project has been quite impressive. This is a top notch reliable family business. They stand proudly behind their name and trade. They are pool doctors. When you see foreman and teams working so fluidly it speaks volumes about the business. From the office to the backyard, hanging upside down to get my pool liner perfect... Hats off to Frank, Emerson, especially everyone here yesterday installing, Tom, Paul, Danielle, Madison, Maryann, every single Sweeney employee who has measured, remeasured, followed up and worked so diligently in the hottest weather to make this right. The pool is turning into saltwater tomorrow and the light and other installations will take place, along with ladder and stair rail. Filters, drains, gas heater as well. New filter. They are neat and clean, professional about everything and we’ve had contractors for many projects here in 4 months. You look and in a minute they’ve got everything clean and specific instructions on how to handle the pool filling up. We turned it off just now as tomorrow the men will return. My husband had hired a different company when we first bought the house 4 months ago. We made a mistake and needed to do this job right. We read reviews and Kenny called us on a Friday evening (thank you to the Mrs). He was so patient and explained this foreign project to us and walked us through it each step of the way. Hard to believe the mess in my yard has been transformed to an oasis. Thank you Sweeney’s. We need you guys to maintain the pool as well and we’re lucky we found you. Kenny, thank you for your patience. I highly recommend Sweeney’s Pool Service."

"Alex installed a new pool liner in a pool that was basically falling apart. It is now a brand new pool ready for the summer. Alex was very professional and easy to work with. Also very honest in helping us decide on switching to salt water which we will have him install next season. Couldn’t be happier"

"Sweeney’s was our lifesaver with our pool in a home we purchased. From Kenny Sweeney’s immediate response to us on a Friday evening from his home to every single professional individual and group he sent to our home he turned a broken down dangerous hole in the ground to a magnificent beautiful oasis in our backyard. The piping needed replacing, the liner, drains and piping were rotten, the filter, heater, electrical needed replacing or updating. Just when the we thought we were ready to go, the pool wouldn’t fill. Sweeney’s sent in a dive team to correct the latest problem. During this entire process, Sweeney’s team was present and completely followed through at every point. They serviced the pool weekly for us. We are so pleased with Sweeney’s. The beautiful ending to the summer of 21 is that my 4 year old granddaughter learned how to swim in our beautiful inground pool. We even hosted her birthday party at our home with a professional lifeguard on watch."

FAQs for swimming pool heaters installation and replacement projects in Stony Brook, 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.
