"Felipe arrived on time and explained to me how he would install the pool rail. He did a clean cut into the cement deck so that the rail could be grounded. The finished job is neat. Thank you, Felipe. I can now enjoy my pool without fearing the steps"

"A long-overdue shoutout to Gonzalez Pools. We hired Favian and his crew to completely renovate our pool with new plaster, plumbing, and tile, crack repair, installing a gas heater and salt system, and pouring new coping and more than 500sq.ft. of oversized concrete pavers. They completed the job on-budget and ahead of schedule. The results are beautiful and matched our complicated design down to the inch. I wish I could post a photo! Definitely, recommend Gonzalez Pools for all your renovation needs!"

"I cannot say enough good things about them.  Extremely responsive, courteous  and professional.  Took great care in wrapping the furniture and in moving it into the house (made sure it didn't scratch the walls or the floors).  Were extremely patient with us when we changed our minds with the the placement of some of the furniture (moved couches from one room to another and back again).  We also had some challenging reassembling issues that they handled no problem.

"We contacted Steve through Angie List because we wanted to give our old 80 style pool a much needed and quot;faceliftand quot;. Unfortunately, to finances a full remodel is not an option at this time so we wanted to do the best we could with the limited funds we had available. We contact several pool contractors and Steve at OC Pool Technicians was the only one who seemed to undertsand our budget and needs. He came out for a consultation and told my husband the possibilities and his recomendations of how to spend our $1000 max budget. Our primary concerns were the staining and discoloration of our white pool plaster, tile, and grout. We also had a missing pool drain cover. Steve told my husband that once the acid bath was done the plaster would be white again and the discoloration and stain would be gone that he could clean up the tile and grout and that he could replace the drain cover and replace the spa light all within our budget. It took about a week to get a written estimate and after careful consideration we decided to move forward. It took about another week to schedule the start of the work. it started with draining the pool which took a couple days, then the repair of plaster on the step, then the acid bath which took a day, then the sanding, then to our surprise with a couple of days from starting the job, he was filling the pool back up. It's here we run into all the complaints...the pool plaster was not all white after he did his job, you could visibly see the same discoloration and while the staining was better it was not by any means gone as he'd promised. We contacted Steve and he responded that that was best it would get and that to him it looked beautiful. Well that's great but to me it looks the same and I'm the paying customer. So we pushed the issue and continued to express disappointment. Then came the excuses...he had one for everything we weren't pleased with...the first excuse... was too old to do any more treatments or sanding and that if we wanted more we would have to sign a waiver releasing him of any libaility or damage to the pool. Feeling very disouraged and not pleased which we communicated to Steve we had him finish the work on the spa light and filled in the pool. Our only request was that he make the tile and grout sparkle to hopefully at least give the pool the illusion of being updated. He said he came out and worked on it several times but it not nuch better either--definitely not how I expected/he promised it to be. When we communicated how unhappy we were with the tile/grout outcome we got excuse number two..now it was it too old and simply needed to be replaced. WOW! Really! we already new that and we're not pool contractors. the experiance and outcome was less than diserable and while there is an improvement in the appearance of the pool its absoluely not what we were lead to believe it would be. It's. About 60% better than it was to start. Absolutely not $1000 better. Of course, he wanted to be paid along the way for the process and upon completion. He offered no discount for the service even though we weren't happy with the outcome. In my opinion he found out how much money we had to spend, told us what we wanted to hear, and made promises to get our business but couldn't ever deliver what he promised to. I've had lots of great experiences with Angie's List contractors this just wasn't one of them.

"The work itself went very smoothly.  Renovating my house, I had dealt with every kind of contractor (painting, construction, floors, plumbing, etc ? see my other reviews), and the guys at Crystal Pool & Spa were by far the best and easiest to deal with.  They were the only contractor that actually finished the project by the date that they said they would (not that I really cared since it was February and too cold to swim).  The whole process took about a week and a half.  One day to demolish the old plaster and tile.  One day to set up the baja shelf and shallow deep end.  One day to pour the concrete.  A few days to let the concrete settle, and then one more day each to add the tile and plaster.  All the crew members that came over to the house were polite and professional, and they always made sure to clean up whatever mess they made.  
I want to point out that when I moved into the house, the pool lights were not working.  I just figured they were burnt out since they were so old, and asked CPS to bring two new lights and add it to my bill.  But one of the workers found out that it was just an exterior fuse that need to be fixed, and did it for free.  So give them a big plus for honesty since they could have easily replaced the working lights in order to pad their bill.  
Finally, what matters the most is the finished product.  I have to say that the remodeled pool with the mosaic tile and baja shelf looks absolutely fantastic.  I felt like my pool looked better than many of the fancy hotel pools in Vegas (although on a much smaller scale).  After seeing my new pool, I wished I would have spent a bit more for some of their other products, like PebbleTec They even contacted me after the pool was finished to make sure that everything was great and that I was happy, and also that my pool guy was properly treating the new plaster.  Would absolutely recommend these guys for any kind of pool work."

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