"Lazy Day Pools renovated my pool a year and a half ago and I've had nothing but a great experience with their service. They repaired our pool walls, installed new pool steps, replaced our liner, redid our pool deck and installed their drinkable water system and everything is amazing! Can't recommend enough. Great service and communication through out the entire process."

"This was the first hot tub we have purchased and couldn’t be more happier. The entire team at Athens Pool and Spa from the owner on down were extremely helpful, answering all of our questions. We had it delivered and installed with Zero issues. We did need have their technician come out afterward to diagnose an electrical issue. We found out that the electrician who ran the wiring to the disconnect wired it incorrectly. The tech fixed the issue and it has ran flawlessly since. Would highly recommend them to anyone looking to purchase a spa."

"The service went fine. I had them install an outlet. I had to pay quite a bit more for the specific outlet I needed. Two electricians came out and completed the job in about 2 hours or so. They did a fine job. I had no problem scheduling the deal."

"What an awesome experience, Seth is an incredible technician when it comes to pools. He explains everything to me about our equipment the right way not like these other companies. He did an excellent job replumbing the equipment in a safety timely manner. I would 100% recommend his work again. Thanks Seth!"

"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."

FAQs for swimming pool heaters installation and replacement projects in Gainesville, GA

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.
