"My pool heater broke on Friday and I searched for pros quickly. I realized that most pool companies don’t work on the weekends but I tried. I sent a request for an estimate to replace my pool heater but needed it to be completed on Monday. The owner of Affordable Solar and Pool Heating replied on Saturday and provided me with an estimate and scheduled the replacement on Monday. The tech, Henry came on Monday. He was one hour earlier and replaced the heater. He was very knowledgeable, Courteous , neat and took the time to explain everything he had done upon completing the replacement. It was a great experience and I was extremely happy with the results. Their work ethics or great and they are very focus on customer satisfaction. I strongly recommend this company."

"My experience with Responsible Pools was nothing short of wonderful, throughout. Dean was prompt, pleasant and thorough with our initial communications, even responding after hours. He arrived the next day, and thoroughly accessed my current pool system setup, then spent a LOT of time explaining detailed various options for me (my "setup" request was a very unique, unusual one). He was honest and instead of trying to upsell, he recommended a smaller unit, suggesting the larger one would be "overkill" for my small pool. The quote for the exact same equipment, warranty and labor (actually, more detailed-labor) was MUCH more competitive and fair as compared to the other companies I'd considered. Upon project initiation, Brandon was on time and did an incredible job with a very challenging, unique pump system setup. He worked mindfully and diligently, arranging a very unique, complicated(due to my unusual request), easy to control, effective system. I couldn't be happier!"

"Judy Sarsten, the Ten Plus Services office manager, was very responsive, pleasant and professional.  The crew assigned to the job, Paul and Dexter, arrived at the time promised.  They showed me the corrosion problem (structural rupture) that precluded fixing the old unit.  When I inquired about replacement options, Paul provided well-reasoned advice about the heat pump and gas-fired alternatives.  I decided a gas-fired pool heater would be best.  Paul said the office would send me a proposal. 
Judy sent a detailed estimate the next business day, including the Angie's List discount and offering to waive the service call fee for the first visit.  The $2500 price seemed fair; it was less expensive than the old unit (purchased by a previous homeowner).  I accepted their proposal on the condition that the work would be accomplished within nine days.  Ten Plus Service made this happen.  Paul and Dexter did an excellent job installing the new unit and the new gas line needed to supply it.  They were pleasant to work with and readily answered my questions regarding various aspects of the installation.  They showed me how to operate it and how its use can be coordinated with my solar panels.  They hauled away the old unit and all trash.
Employing Ten Plus Service was a pleasure from start to finish.  The heater is working very well, as evidenced by a 5 degree Fahrenheit water temperature increase over two hours, even with the outside air temperature below 60.  I am very satisfied and will gladly hire them again.

"I’m writing this review because this company did not do a good job, they did a GREAT job. Today it seems most companies just want to do the minimal to get by, well that's not the case with Tropical Pools. They did the best resurfacing on our existing pool that money can buy and they were very reasonable with their price. Not only did they do the job as per our contact. But each day they cleaned up the area around our pool deck and made contact with me as to what they have done and what they plan to do next. Keeping us updated gave me and my wife piece of mind. That in itself is priceless! The job was completed within the time frame that was stated in our contract and at the price quoted. What more can I say? If you are looking for an excellent pool company that has ethics and morals look no further than Tropical Pools of Central Florida."

FAQs for swimming pool heaters installation and replacement projects in Lithia, FL

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.
