It was my first time at RC and experience was rewarding. As soon as I stepped through the door I was greeted by Dominic, a very knowledgeable young man but more than he was respectful, kind and very helpful a man any GC would like to have working for him. I would recommend RC to all my clients.

In the middle of all of the heat and smoke of August, 2020, I called RC Mechanical to fix my old air conditioner. He arrived 20 minutes later, had the replacement part in his van and even dealt quickly with some power labeling issues. I can't tell you how much I appreciated his prompt and friendly service.

Sal at RC Mechanical is the best! He installed a new furnace with AC, which we did not previously have, new ducts where accessible, rebalanced the airflow, resized vent openings. He gave us lots of options, was thorough in explaining everything and gave us time for decisions. I thought at first that his bid was high, but after some research I realized it actually reasonable, and it would have been worth it anyway.

The work (he does pretty much everything himself except electrical) is meticulous and he wants to make sure everything is to your satisfaction. He was also very patient with my engineer husband's bazillion questions. My only complaint, if you could even call it that, is that the time estimate for the work was 3 weeks and it took twice as long. But that is really just a nit pick, considering the quality of work.

Calling RC Mechanical for my A/C unit was the best decision I could have made. Sal was accommodating and helpful. He explained why my A/C unit was having issues and what was needed to get me back up and running. Excellent response time. Fair prices. THANKS SAL!

Sal added a brand new HVAC system to our house last year, since that time we've had a few questions about the system-when we call Sal he is always highly responsive and goes out of his way to help us out. He is everything that you want in a service provider: honest, professional, detail-focused, fair, and a genuinely nice person. He offers amazing value for your money. Don't waste your time with other vendors, Sal is the go-to pro in the Bay Area!

Sal was extremely helpful on the phone, he helped me troubleshoot a blower motor problem. I know in the future when I have a problem I cannot fix I'll call Sal at RC Mechanical.

Update: I did fix the flue, as Sal didn't have the equipment to do it. It was certainly dangerous and Sal did find the problem, but it had been like that for 15 years since the furnace was installed, and was not the cause of the problem. The problem required additional troubleshooting and replacement of the control board, which I also did. Sal is a great guy and offered to refund our money, but I think it's fair to pay him for his time, I will not take him up on his offer.
