All around A+ for the whole team at Cal-Air. Our AC went down and we had another Company come out…read moreto the house. Their tech was great but their process and pricing seemed very high. They were not certain they could fix the issue. I called Cal-Air and explained our problem. They were confident in fixing the issue, quoted half the price and came out the next day. Josh and Jeremy were amazing. They spent a few hours finding the leaks, fixing them and getting us running again. The cost was less than half (even lower than quoted) and the experience was amazing. I chose Cal-Air because of the Yelp responses from the ownership. It makes me feel better when people care enough about their customers to comment on their likes and frustrations. Kudos to the whole business and the folks running it!

May 2025 plumber came out after line they fixed broke for the 3rd time on outside faucet…read more Incompetent for the start since house is only 20 years old at time this started so I don't buy into outside wall was issue now. Only a few feet are on outside wall. He suggested to have line in poly tube over cooper and we agreed. The company was to have someone come out to do so. After months of no call I called beginning of March 2026 asking what happened, we need it fixed and wanted someone to do so. Schedule only allowed for two weeks out approximately. Scheduled and blocked day off. Now today plumber comes out and it's the original man who can't do any work due to injury. so he calls office and now they want to schedule it out again. Incompetence of this company is ridiculous. We had 3 other jobs we needed done too and they will not get the work. Time to find a reliable plumber.

They are thorough, reliable, and timely! Got the job done and then some. 10 stars if I could!!!read more

They cleared the…read moreline, however, the final total was quite a bit more than what I was verbally quoted by the owner. This is in a rural area where there aren't very many options for plumbers, especially in an emergency situation like I had. I am grateful that they cleared the line and installed a clean out, pretty much left the mess in the cellar of some of the blockages. I thought I'd give them a second chance with a small leak in a waterline in the cellar. I did not receive an answer when I called so I left a voicemail. I did get a callback from the owner who told me that they were no longer in business, and that he retired, and was attempting to sell his business.
