What sets us apart
Why a union shop actually matters to you
- Apprenticeship-trained techs. Every technician goes through a structured, multi-year training program — not a weekend certification course.
- Real safety & code standards. Union shops answer to stricter safety and workmanship requirements than most independent contractors.
- Accountability, not disappearing subs. You're working with our employees, not a rotating cast of subcontracted labor.
We’re the guys you want to find but never could – until now!

What Orange County homeowners say
Real Google reviews
Scottish Tom is an excellent small local business. It was wonderful having seasoned professionals come over with an apprentice to learn on the job. There were no sales pressures for unneeded work or subscription services.
I've worked with a lot of contractors over the years and it's hard to find contractors who actually care about doing a good job. Tom is truly one of the very few I've found that does, and I can't recommend him enough.
I want to thank you for the excellent work you did installing my digital thermostat. From the beginning, you were very punctual, professional, and friendly. You took the time to explain how the thermostat works and answered all my questions patiently.
Even though I am across the country and posed no real value to Tom he took the time out of his day to have a conversation with me and discuss some of the mold protocol questions I had after talking to a local contractor. I was referred to Tom by a friend and I wouldn't hesitate to recommend him to anyone.
Scottish Tom was a very professional crew that did some work back in May. Their work is really good and it stands out. I love how they fixed my system and got my house back to cool — definitely recommended!!!
Very happy with the work. Replaced my AC unit, these guys did a clean job. Looks great and works amazing. Great communication and they completed the work within the planned time frame. Well deserved 5 stars.

Tom is always knowledgeable, honest, and reliable. You won't spend money on things you don't need.
Tom is knowledgeable, personable and efficient. His expertise is heating and AC, but he can do just about anything. I trust him to be honest and fair. I highly recommend him to anyone who needs a smart, honest hard worker.
Tom is very professional and honest. He is on time, quick to diagnose and detailed with his explanations. 5/5 will recommend!!
I am fortunate to have found Tom. First hot weekend of the Summer and of course my unit breaks down. Any salesman would have told me that it's time to replace a 30 year old unit and charged me to inform me the obvious.
Tom was very thorough in explaining exactly what he was doing. Showing every step of the test to see if our furnace had a cracked heat exchanger. I learned so much good information, so that I'm more knowledgeable about our furnace.
I recently had a problem with my AC and had to update my whole system. I talked with Tom of DaVinci Mechanical, and he gave me many options to help me fit my budget. His knowledge about the HVAC industry was impressive.
