All reviews for SIGMA Mechanical Services

It’s good

Excellent service and technical expertise. Reasonable prices

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

Phenomenal company always do an excellent job 💯 thanks so much for always helping me out

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

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

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

Jeremy is the BEST! We had been through everything with many other technicians and other companies. He came out, knew what we needed and our heat hasn't stopped working since he left. THANK YOU THANK YOU THANK YOU!

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!!

Every time I’ve had to call them for repairs over the years (usually for AC on the hottest of days of course) they’ve been great. I appreciate that they explain the issue and communicate well throughout the process. Highly recommend.

Just had 2 condensers repaired by Jeff. Couldn’t be happier. He accurately and quickly assessed my issues. Resolved them in an extremely timely manner. I will be calling Sigma for all of my future ac/heating needs.

Can’t tell you how much I appreciate this service on a particularly hot day.

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

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.

Don't use!! We've used them as our service provider for heating. Woke up to a massive flood and water shooting out of our unit at 5am ( I suspect they didn't inspect or fix it appropriately during our annual maintenance). Called at 5am and got the call center. They took all my info but got no response. Had to figure out how to shut down the water and unit myself while cold water was spraying everywhere. Called back again at 8am and got call center again. They said they sent the message and tech got the page at 5am when I originally called. Yet no call back from the tech or anyone! Had to call back again at 9am. This time got the office. The woman on the other end couldn't have cared less that my basement was flooded, I had no heat or water, that we're regular customers and that no one called back. She said the tech was on vacation! So why have a calling service if you're not going staff it appropriately or care to respond? Frankly, if the tech called me back and said he was on vacation I would have been fine with that so I could have moved on to another emergency service sooner. Good service and communication really isn't that hard.
