Peterson Mechanical

Scott did an amazing job at installing an HVAC system for my place in Sonoma. He provided a well considered estimate, which was detailed and well documented. The work was done on time and efficiently. Also the final product was great — super good to have it properly and professionally installed. The working crew was highly professional. Thanks to Scott for the work!

I’ve been a Peterson Mechanical customer for years and they are fantastic. I highly recommend them on a regular basis and will continue to do so. I’ve used them for my home as well as my office and they’ve been great at both the residential and commercial side. They are always honest and timely.
They are a family owned and operated business with deep roots in Sonoma Valley which is important to me as a Sonoma local.

July 1, 2013. The recent hot spell has caused us to turn on our air conditioner. Yes, the one Peterson Mechanical specified, installed and repaired. As it has since each summer since it was put in, it failed to work. We called a new HVAC company to service it. They came out and the connection to the compressor was leaking. This is exactly the repair that Peterson did less than a year ago. for a cost of $ 500+.

I’ve used Peterson twice now, this time for a heater repair. They were prompt, quickly determined the problem, and immediately made the fix. I will use them again.

My experience with Peterson Mechanical has been unacceptable. They came out quickly but the quality of work was not acceptable. They made an error in sizing (too small) a ventilation grill that resulted in the unit whistling and refused to fix it. Since they did the A/​C installation, I would have thought they would have been able to size it properly.
Also, the technician they sent out to run a thermostat wire was unable to run the wire and called for another technician and they then billed me an excessive amount for running the wire. It was a simple wire run of about 20 feet and into one wall. There is walking clearance under that portion of the house, so running the wire across 20 feet and into the wall where the existing wire was shouldn’t have been a problem.
When I spoke to one of the managers at the company (same last name as the company so I assume he had some authority), he essentially told me too bad. He offered to replace the ventilation grill with a different one, but only if I paid their hourly rates.
When I asked him about the excessive time the technician spent running the wire his response was they are «a time and materials shop.» When I asked him why I should pay standard rates for a technician that didn’t know how to do a simple job, he told me that if I didn’t pay the full bill they would take me to collections.
Frankly, I don’t think I’ve ever had a worse customer experience with any local service company. (The phone company, etc don’t count).

I have complete and utter trust in this company — one that we have had to use sparingly over the last 15 years, but each time a problem was resolved quickly, efficiently and for far less money than we had been quoted by other companies. They are excellent at both furnace and air conditioning repair and we will continue to use them– but now without even comparing their prices to others because their quality is excellent!
