Encountered problems with an older AC unit in a new to us home. The technician did a fabulous job of explaining the causes and providing options for repairs or replacement. We decided to repair at this time and will definitely be reaching back out to Cencal Heating and AC when it comes time for replacement. Service:HVAC system maintenance

Cencal is awesome! Their office staff is always super friendly and upbeat, their technicians are always very professional and helpful! They do a great job on keeping my system running, and now I have ordered a new system through them that will be installed next week! Special kudos out to Kha who was here today and has been here before. He is always professional and on time and does a great job! He was super helpful in ordering my new system. I would love to have him come every time! I definitely recommend this business!

I did not have work done by this company (and never will) but their lack of professionalism prompted this review. Two of their work trucks were blocking a thoroughfare alley way which is used by dozens of parents every day to drop their kids to school. I happened to be the first parent to arrive and explained that there would soon be a line of cars and could they move their trucks for a little bit (there was plenty of street parking for the trucks).

I was flat out told "we don't care" and laughed at. Any other parent who said something to them about the alley needing to be kept clear or asking them to move was met with the same smug and unprofessional response. Calls to the company produced a canned "sorry, " but they did not require them to move, at least not before all of the kids had arrived and school started. They claimed that they can park wherever they want, yet the photo shows each truck parked directly next to a City "No Parking in Alley" sign. How embarrassing for their company. I certainly wouldn't want these guys in my home.

Professional and thoroughly executed job with unparalleled communication. They were done quicker than they estimated, and operated with efficiency and treated our home with care while working around our kids and difficult circumstances. The rebate information arrived from the company and was pre filled; with an envelope and stamp of where to mail it, including a follow up call and email to ensure we had no questions. Additionally and of course, our new system operates incredibly efficiently and without issue.

Cen-Cal Heat and Air. Fantastic people from office and phones to technicians on-site. Jason did a fantastic job on our heater. Fixed a problem we have had for a few seasons and provided options if his repair did not fix the problem. They are a customer driven company and I would recommend them to anyone.
