"Above ground pool was opened.  They took the cover off, folded it up and placed it by my shed, filled the pool with water and treated it with chemicals.  However...they did not fill the pool enough to run the filter, did not put in the stairs or check to see if my heater was in working order as requested over the phone.  I was not notified in any way about the status of my pool heater.  No report or bill of service was given.  They charged the wrong credit card and left their tools on my deck.  Also, not very customer service friendly over the phone.  They seem almost "bothered" when I called to request their service.  Needless to say, I will not be using them again. <br />"

"There was a terrible storm overnight and my pool and spa looked horrific my pool was green and had a bunch of leaves and branches in it, I was hosting a big party for an engagement celebration the next day, so I was very stressed out, I had called other pool companies and received no response, when I reached out to Marco, he responded right away, was very empathetic to the urgency of my situation and he was able to come first thing in the morning and he made my pool look amazing! He’s a very honest and extremely professional person, I will only ever trust him to work on my pool from now on! He’s the best person you can ever hire to work on any and all of your pool needs! "

"Very happy with PJs Pools. Needed the heater fixed on our pool. They came out and had to order a part. Ordered the parts needed and had it fixed in a couple of days at a very reasonable cost. Heater is working great."

FAQs for swimming pool heaters installation and replacement projects in Crystal Lake, IL

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.
