"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."

"Words cannot express how impressed we are with the services provided by Moore Pools. We have tried at least 4 other swimming pool companies and all of them had poor customer services and zero results. We literally poured hundreds of dollars down the drain working with other companies. Hunter was able to come out and find the leak immediately!!!! More impressively, he has great customer service and an excellent communicator. He kept us informed and kept his appointments as scheduled. He went above and beyond to get our leak fixed. He was truly our blessing in disguise. I would not recommend any other pool company. Moore Pools will get ALL of my business from this day forth! Thank you, Hunter and Moore Pools!!!"

"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."

"The project went overall very well and the price was very good. Everyone seemed very knowledgeable and the owner was extremely helpful in addressing several of our concerns. They did a great job grinding out the cracks, smoothing the uneven surfaces, re-pouring a section that had raised up that sat on the pool edge, and covering it all with CoolDeck. The technicians came right on time and worked all day long for 3 days. It looks like we have an entirely new, re-poured deck now. Our three complaints are that our neighbor saw that that the technicians poured some mix or something into the storm drain when we were out. That's a no-no. Previously they poured some into a catch-basin of ours which drained into our neighbors larger drain system. He told us and was not happy nor were we. I also wished that their grinding tool had some kind of vacuum system on it. Instead, we had huge clouds of dust around the house while they were grinding. The second complaint was that the color was lighter than we expected from what we saw in the sample. The third complaint is that my wife is seeing a hair line crack forming around the pool where the owner suggested we have a coping cut line made, but which the concrete workers rejected saying it would weaken the structure too much. Now we may need to have them come back and make the cut line after all... and a ton more dust."

"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!"

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