"Sweeneyâ  s was a lifesaver. We bought a house with a pool that needed a complete overhaul. After many interviews with others, we thankfully discovered Kenneth Sweeney. Carefully recovered, replaced the lining, drains, filter, electrical, provided gas pump, and worked with gas company to ensure all was safe. We needed a new cover, they also serviced the pool weekly. This is a serious investment and so vital to hire a safe company with quality and professional staff that care. Sweeneyâ  s team is the best. Finally the nightmare we started out with turned out to be an oasis in our backyard. My granddaughter learned how to swim this summer and we hosted her 4th birthday celebration with a lifeguard in our backyard. Thank you Kenny and team for making our backyard a vacation spot for us and our family. We are truly grateful for you."

"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"

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