"Dave is a true professional that believes in doing things the right way, even if it takes longer. He thinks about all the details, which is critical for larger, complex projects. I hired Dave for a new panel install, new wiring for 800 sq ft, and cleaning up some old electrical work. His input on lighting choices for rooms with angled high ceilings was much appreciated. Would definitely use him again."

"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."

"The technician did an excellent job. It did take a while to get the repair finished, but that was due to Bertazzoni delivering the parts. I have had multiple problems with this particular appliance. My range now works better than it did when new, but I have a feeling that even if I have continuing problems with it, American Home Shield will just repair rather than replace due to the cost of the range. By the way, I'm not exactly sure of the date of the repair."

"Once the contract was signed and all required parts were available Sylvester electric contacted us and scheduled the installation. The technicians arrived on time as scheduled and the contractor kept in touch with us via phone throughout the project. The staff is professional and very respectful of our home and property, all work was completed as promised, the job site thoroughly cleaned each day, and a daily update was provided by the technicians before they left for the day. The job was completed to my full satisfaction as promised.
I would not hesitate to contract with Sylvester Electric for all my future electrical service needs."

FAQs for swimming pool heaters installation and replacement projects in East-derry, NH

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.
