"I write this review as an 8 year customer, soon to cancel. The service for the first 6 years was only weekly chemicals, with no issues. Once their price for weekly service doubled and included emptying the baskets, then the issues began. Their technicians would constantly not empty the basics, leaving them full of debris. I began sending them photos and security camera video of the technicians walking right by the baskets and not even looking at them. Now the worse part, dealing with the company. I would never receive a call back. The "service" manger Phil would never return a phone call, and it would take an act of congress to get him on the phone. The poor woman that answers the phone, although very nice, has no power to do anything. These issues have gone on for months, leading to finally canceling the service. I'd rather pay slightly more for a company that can fullfill their services. This company and its service has fallen apart. I would not recommend. "

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