"Felipe arrived on time and explained to me how he would install the pool rail. He did a clean cut into the cement deck so that the rail could be grounded. The finished job is neat. Thank you, Felipe. I can now enjoy my pool without fearing the steps"

"A long-overdue shoutout to Gonzalez Pools. We hired Favian and his crew to completely renovate our pool with new plaster, plumbing, and tile, crack repair, installing a gas heater and salt system, and pouring new coping and more than 500sq.ft. of oversized concrete pavers. They completed the job on-budget and ahead of schedule. The results are beautiful and matched our complicated design down to the inch. I wish I could post a photo! Definitely, recommend Gonzalez Pools for all your renovation needs!"

"I cannot say enough good things about them.  Extremely responsive, courteous  and professional.  Took great care in wrapping the furniture and in moving it into the house (made sure it didn't scratch the walls or the floors).  Were extremely patient with us when we changed our minds with the the placement of some of the furniture (moved couches from one room to another and back again).  We also had some challenging reassembling issues that they handled no problem.

"I highly recommend Steve and his crew at O.C Pool Technicians. They are professional and a pleasure to do business with. They were very flexible with any changes I wanted to make and always had time to answer my questions. He came up with a plan to fit my budget and there were no unexpected extra costs. I will use them again for any future projects"

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