"We have had a pool for 14 years. We have used several pool companies and always felt we were getting the run around. Matthew came out and gave us a fair price to replace our pool heater and change the gravel in the filter. Not only that he educated SO MUCH on our pool we were shocked and how little knowledge we had. His wife Jesse is also a delight to speak to on the phone. A++++++++ BEST pool company around!"

"He did a very good job.  Be prepared for all of the extra's they will ask for beyond the initial deal.  I will say we have a lot more airflow going through our heater now and the dryer really needed it.  We had two cancellations before they came on the last time.

"During covid we didnâ t have anyone maintaining our pool. I found Hugo last spring. He came out, assessed the situation, and was able to get our pool in working order pretty quickly. We also ended up needing a new pool cover which he was able to install himself. It looks great. Heâ s been quick to respond to phone calls or texts, and takes care of the maintenance quickly, and prices are fair."

"My husband and I are extremely happy with the finished product. Todd and his crew cleaned up every day. They were perfectionists in their installation taking the time that was necessary to do the job correctly. They were so quiet that there were times you did not even know they were in the house. The price was exactly the same as the bid. Todd is a talented craftsman who cares about the final product and respects the needs and wishes of the people who engage his services. We would strongly encourage others to use his services."

FAQs for swimming pool heaters installation and replacement projects in Kirkland, WA

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.
