"I signed the contract for replastering my pool for $9,300 with Alex on April 4, 2025. All the contractors talked about the length of the project to be 2 – 3 weeks. The payment terms were 50% upon demo, and 50% upon completion. I left the time of completion empty, because naively I thought that they would be eager to complete the job. My ratings are: Price 5 star; Quality of work 5 star; scheduling of work 2 star. Average rating 4 star. Alex was eager to do the demo, because this triggers the first 50% payment. Demo was done on April 16, 2025. We also amended the contract to install new lights ($1,200) and replacement of Deck O Seal ($1,800). New contract price $12,300. My payment of $6,150 on April 16, 2025. The value of the Demo may be about $3,000. I therefore had now paid about $3,000 in advance. Waiting and waiting. Alex is texting: Out of town, mother in hospital and then two weeks later: death in family. Ok, I expressed understanding Continued on attached jpg"

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