"Michael installed a new pool/jacuzzi heater as well as automating our system. We can access pool and jacuzzi from our cell phones. Michael completed all work on time and on budget. He was very responsive to our needs and answered all questions we had about the new system."

"It went extremely well. They were fast and efficient. I was told that there was no hope for my swim-spa and that I would need to replace. They made my spa look new again!!"

"Precision Pool Techs installed our electric heat pump and did a great job. We had 5 companies quote the job, and they were one of the lower quotes we received at the same time as presenting themselves as experienced professionals who knew what they were doing. After the heat pump was installed, they spent time answering our questions and ensured that we understood how to operate it while minimizing our electric bill. I would absolutely recommend them to others and will use their services again in the future."

"Outstanding work by Scott, who beat every other price out there by a lot, and still managed to go above and beyond, being a great resource for helping us get a DWP rebate that ended up balancing out the cost of the installation! I cannot more strongly recommend a company than I would Better Buy Pool Supply. They won't be beat!"

"I contacted them for a quote and they called me within 10 minutes. Explained what they would do and the cost. (I also had two other quotes, 1 company was a little more expensive, the other quoted long distance rate). We set the date and they explained the cancellation policy. They called the day before the move to re-confirm the time and asked if I had any questions. The next morning two young men, Jason and Serge, arrived on time. They were prompt, professional, hard workers and had a great sense of humor. We walked through the house so they would understand what was being moved. And then they started. They worked fast but were very careful in wrapping and organizing everything. Once loaded, we headed to the new place. Several items needed to be moved out to go to another location which they did very quickly. Then everything was unloaded, we headed to a second location to drop off items and pick one up to return to the condo. Everything was moved without a dent, nick, chip or any breakage. They arranged furniture for me and put together things they had taken apart. They did the complete job in just 5 hours. I would absolutely hire this company again. I was very pleased with them."

"John called right away to set up appt. to install pump and motor to replace one no longer working. Set apt for mid-day in 3 days, I asked him to call first so I could put in dog door which he did. He was right on time and brought treats for Foxy and made friends with her before starting. He did a great job with installation and gave me a lot of information about pool. I asked for estimate on project I wanted him to do and he was very thorough about what it entailed. Unfortunately with us being retired seniors we couldn't afford it right away but he didn't push and just said to let him know when we were ready. I liked that. We will definitely be calling on him as soon as we can. John was very personable, and knowledgeable . I was very impressed. He even gave information and tips about things that had nothing to do with the installation. Very pleased with service and John. w"

"polite, friendly, cheerful, and knowledgeable personnel.  However, they lived too far away to continue to service the pools.  We parted regretfully due to geographical differences.

FAQs for swimming pool heaters installation and replacement projects in Lake Forest, CA

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.
