"Joe has been taking care of my pool for 20 years and I have never had a complaint. He and his staff are courteous and professional and always show up when they are scheduled to. In addition to opening and closing my in-ground pool, he has replaced the filter, heater and two years ago, the liner. All the work went smoothly and was the best of quality. I highly recommend J s Pool Service."

"Simpson Home Solutions remodeled my bathroom. Took it down to the studs and created a beautiful room for me and my family. Khristopher also maintains my pool including opening and closing. He is always punctual and professional. His prices are fair and I'd trust him to fix just about anything in my home."

"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."

"I had just moved to the house with the pool and knew nothing about pool maintenance. The previous owner had taken some necessary pool equipment with them and the condition of the equipment they left was not great. Equinox provided all that was needed at half the price quoted by other pool guys

FAQs for swimming pool heaters installation and replacement projects in Haworth, NJ

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.
