Ernie and George were awesome to deal with and worked hard to get us on the schedule to replace our AC unit even with the HVAC buiness being straight out. Promoted, courteous and professional!!

Our AC turned off yesterday and even on a Sunday they answered our call and scheduled us an appointment for the following day! They service central AC, which is rare. Super friendly, very insightful, and reasonable pricing! We'll definitely be using them again in the future! Choose Cal's for you air conditioning needs!

Ernie was great! Found him on Angie’s list and couldn’t have been happier. I received 4 quotes for a ductless split system on my home with an air handler for the second floor and an in-law suite as well. Ernie was extremely competitive with his pricing. Ernie was on time, extremely clean and meticulous. He even vacuumed the house after installing. He took the time to explain in detail how everything worked and the most efficient way for everything to work as well. I Highly recommend Ernie, you’ll be happy you hired him.
