"Michael and Jake did an incredible job inspecting and cleaning our AC systems. Very knowledgeable and exceptional customer service."

"Mike was very willing to investigate an A/C problem we knew was more than just a maintenance issue. By identifying the cause of a blocked airway and discovering the likely cause of 100+ gallons of water in our duct beneath our floors collecting in the registers, Mike probably saved at least $10,000 - $20,000 in future leak repairs and collateral damages."

"Thomas and Michael were amazing! They were punctual and friendly. I would recommend them to all of my friends and family."

"Mike the owner is a pro's pro. He has an extensive background in commercial work.And it really shows the advantage for residential HVAC. Two other companies looked at our unit and immediately tried to sell us new systems. Mike overviewed the advantages of my new systems but also took time to point out that a repair might be more economical and valuable. That is what we did and will replace the unit through Mike when the time comes because we trust him so much."

"Efficient and knowledgeable. Fair pricing."

"We contacted Michael at 4;30 on a Saturday afternoon about our elderly neighbor's thermostat issue. He called back in a few minutes and arrived at the home within 90 minutes. He found the issue and was able to repair it at a reasonable cost. We are very grateful he was willing and able to help our neighbor on what was going to be a cold night. I highly recommend him."

"Michael and his crew are as good as it gets for both HVAC repair and system installation/replacement. With their help, I was able to get by for quite some time with a failing system, and when the time came for a full system replacement, Valley Center Air Conditioning did an incredible job from start to finish. Despite the strange configuration of my mid-century custom home that has left other HVAC installers puzzled, Michael devised a really clever solution that helped to avoid cutting floor joists and/or losing a closet. The new heat pump works flawlessly and is already providing extraordinary energy savings. On top of all of the praise I have for the work that VCAC has done for me, Michael is also a delightful human being whom I trust completely to work on and in my home. Highly recommended in every way."

"I was referred to VCAC by a friend. I live in Valley Center and recently bought a house. The AC was had gone out and I called 2 different big brand companies to repair the AC I had currently and they said because of the age and condition the couldn't repair it but they left me with a $25k quote and a $30k quote for a new unit. Mike came over on time and fixed my AC for a fraction I was quoted to replace the Air Conditioner. Mike was professional, knowledgeable and very to the point. He left me with a working AC and a quote that I felt was a pretty good deal. I will definitely be calling VCAC back out when its time to replace my current unit."
