"Overall very pleased. Roger was the first to respond to my request for service. He was also quickly able to schedule time to asses my hot tub repair. He was generous in sharing his knowledge and recommending actions and equipment for good maintenance. He sent another person, Preston to install the new part. Preston also went out of his way and repaired the door to the cabinet of the hot tub."

"I decided that I wanted a standby electric generator for my house. Not knowing anything about generators, I began looking for advice on exactly what I should purchase. After talking to several electrical contractors, Tri-City was obviously the most knowledgeable on the subject. Chad (of Tri-City) helped me choose the right generator for my situation, with no promise that I would use him to do the installation. He and his brother Jason came by here to look at my situation and didn't try to get me to commit to anything or try the old trick of "We'll knock off the charge for the estimate when we do the installation". After I had chosen a generator and had it delivered, (I got it from electricgeneratorsdirect.com), Chad and Jason came out here and built a wood-framed gravel pad, made sure it was level and attractive, then moved the generator from my garage and placed it on the pad and did all the connections that were possible before the gas company came to perform some necessary modifications. After the gas was hooked up, they returned and completed the installation. Not only did they do an outstanding job, they stayed around for a couple hours testing it to make sure it was working properly. I no longer have to think about who I will call when I need anything electrical done! These guys are head and shoulders above any other electrical contractor I was able to find!"

"They ordered and delivered the wrong style metal roof which did not use clip fasteners but rather screwed directly to roof. This will not allow expansion of metal roof. Also, the installation crew left 1” gaps on the edges of the ridge cap between each standing seam. This will potentially allow wind blown driving rain to enter my house."

"OMG!! Where have these guys been hiding! I called several other companies because my pool was continuously losing water but none of them could seem to find the source. Within about an hour these gentlemen concluded that I had a main drain leak. They repaired the leak the next day and also took over the pool maintenance service. (They even pressure washed my deck!!) My pool has never looked nor functioned better. I would highly recommend the professionalism and knowledge of these men to anyone!"

"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 Mount Holly, NC

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.
