"From the first, pleasant phone call to set up an inspection for the quote, to coming by to show me how to use my all new heater and filter equipment (i was not home when they completed the work) after completion, it was a pleasure to deal with TM and especially Thomas. He was thorough, gave an honest evaluation of my existing equipment and pool condition, gave me several options, what he recommended and what he felt was not needed and then itemized everything so I could choose what I wanted to have done.... no surprises. I would definitely recommend them for replacing your entire equipment set up, and will be calling them to resurface my pool when it comes time for that. Thanks Tommy!"

We pride ourselves on delivering reliable, quality work, while maintaining open communication with clients and acting with integrity. Our expertise is our primary asset, and we will strive to keep you as informed as possible. We are always willing to work with new clients, but the high lead fees from Angi's have made us unable to respond to every new construction and remodel lead. If you'd like to work with us, don't hesitate to reach out directly.

"I had a structural issue in my pool, before then I had at least three other companies come out to analyze the issue. When Dan came, he made it so simple and fixed it for me for less than half of the other companies said it would cost. He also followed up with me to make sure that it is fixed. I recommend this company to anyone with any pool issues. If he can’t fix it, he will lead you to the right solution.. then will always be my first call if I ever have any structural issues around my house or if I decide to build a new pool when I move."

"This is my one-year anniversary of using Ogre Dan's pool service and I couldn't be happier with the results. I used to maintain my pool myself and every year around this time I would be fighting the black and green algae. Now my pool is beautiful, clean and blue. I'm so looking forward to having the family over for swimming this year and I have Ogre Dan's service to thank. Erin, who services my pool, is always courteous, responsible and efficient. In addition, he is always careful to look after my dogs when he is on-site. He even picks up my Amazon deliveries and brings them up to the house. These guys are the best and I recommend them to anyone who wants quality pool service."

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