We've been in business since 1991, providing honest, reliable and competent pool equipment repair and installation. All equipment is sold at wholesale prices with installation built into the sale price.

"We have experienced very inconsistent service at the Pasadena location. The service personnel have been changed four times within the past year, and each transition caused delays as new staff took time to get up to speed. Additionally, one of the two pools has not been properly maintained for several weeks."

Absolute Pools Resurfacing Inc. specializes in pool resurfacing using our top of the line Absoluteglass (fiberglass). We have over 26 years experience and also do pool and spa repairs. Our main focus is to please our customers with our amazing, and detailed work. :)

"The fiberglass surface appears to far superior in durability to typical plaster, and pebble-tec. The warranty is 15 years and expected to last longer and stay looking new. We could choose the color we wanted. We had severe cracking issues in our old plaster and the work done to correct that for the future appeared to be exceptional. I had never heard of fiberglass resurface for a plaster pool, and I am so glad that I found this as an option. The company and its people were all professional. The work was done in a timely manner. The final product looks so good. They retiled for us as well and that work was also excellent. The person used to replace all the filter/heater/pump was also excellent. The price was more than typical basic plaster, yet if that lasts a couple years without discoloration or chipping, I believe the cost is far better. I am very happy with this company and their services."

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