Customers say: Quality work

"I used several pool companies in the Cornelius area and was not satisfied with their customer service and quality of work. Matt successfully diagnosed and repaired some issues we were having with our pool equipment that the other companies could not. Matt's level of service and care for our pool is phenomenal. I highly recommend Escape Pool Cleaning!"

"Preston was very professional and friendly. He was upfront about costs and options for his work with our patio and firepit. He also installed some shelves for us. He ended up needing to do more work on the installation due to imperfections of our walls and did so very diligently and professionally. He was clean in all his work and finished the projections to completion."

FAQs for swimming pool heaters installation and replacement projects in Mooresville, NC

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.
