SIGMA Mechanical Services

We have had the technician Jeff out a few times for repairs he is always professional, courteous and on time or early. Highly recommend.

Their service and prompt attention to our needs was wonderful. We had a complete HVAC install on 2 levels of our existing home. The techs were very clean throughout the 5 days it took for the install in every room. I called three different companies, received 3 different quotes and Sigma's price was not the least expensive, but competitive. I highly recommend giving them a call.

Sigma installed central AC in our home this spring. The entire process was handled perfectly, from the initial scope / order process through installation and testing. The men installing the system could not have been friendlier or more professional. They cleaned up after every phase of the job entirely. The installation was flawless. We worked with Rich in sales and he too was professional, returned calls promptly and was a pleasure to work with. No complaints!!

The technician Jeff was awesome very professional came earlier than scheduled which was great told me everything going on in the process highly recommend

Charged $135 to be told they couldn’t install a WiFi thermostat to my heat zones. After 10 min at my house was told I needed electrician to fish wire. In actuality, the wires were right behind the thermostat and the transformer right at the boiler. Shame. Should have reversed the credit card. Beware.

Sigma has always been a trusted company in my mind. They stand by their work, what else can I ask for?

First time customer. They were great and under budget. I would highly recommend them.

Excellent service and technical expertise. Reasonable prices

Do not recommend. Did not call back. Moved on.
