"I reached out to Louis with a time sensitive request to take a look at a pool which was located on a property I was considering purchasing. Despite being fully booked Louis made the time to stop by the property and provide me with an honest assessment of the pool as well as items I should watch out for. It was clear from working with him that Louis has developed a deep expertise in this area due to his years of experience and will certainly look to work with him further in the future."

"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."

"Choice was fast, efficient, and kept me posted on the progress of the claim. Although the water leak issue was discovered on a Friday, they had a plumber there to investigate by Saturday morning. When it was determined that the 20+ year old heater needed to be replaced, the replacement ordered, on-site, and installed by Wednesday morning. I am glad that we opted for the Choice Ultimate plan as other than the initial $65 service fee, all but one $50 ancillary expense was covered."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

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