With a new baby and temps below zero our furnace died. When other companies laughed at my request for same day service, Sigma was prompt in their response reasonable with their quote and everyone we worked with was delightful. These guys do business the way it should be done. Dan, Chris and Sergio all were so great to work with and my heating system was fixed and we were warm again in no time at all. I would recommend them to anyone and will absolutely be a return customer.

Sigma installed central AC in our house this spring. The entire process was handled in a professional manner from the sales (Rich) through the installation and testing. The install crew could not have been friendlier or more professional. They even cleaned up after each installation process and left the house as clean if not cleaner when they were done. The cost was similar to other companies, but the service surpassed all of our expectations. A top notch company!

Horrible experience. The sales guy Rich promises the moon and then shrugs his shoulders with a big smile on his face when the job falls apart.
Where to begin — we were getting central AC installed. The job was supposed to take 4 or 5 days. They were a no-​show for the first install date (Rich ‘wrote it in his book wrong’) and then when they finally came, it was a disorganized mess. A) they took 12 days to complete a 4 day job; there was excuse after excuse as to why half the crew didn’t show up each day. B) different install guys each day, so nobody knew what the guy before him had or hadn’t done C) they used bulky plastic (ugly) vents to cut corners, and D) they installed the vents in the ceilings in haphazard spots versus centering them to the room or the windows to create any sense of aesthetics or symmetry.
We voiced our opinions many times to both the overseer of the project, Rich, and the install guys, wrote several emails with our frustrations — we even contacted the owner who just referred us back to Rich. No apologies, no discussions, nothing.
The experience was so horrible that I was having nightmares, and literally began having to leave the house when Rich came over to inspect the horrible job.
The only positive thing I can say is that the install guys were nice, and often cleaned up the mess before they left each day.

I had a new Lochinvar high efficient gas boiler installed and I could not be happier with it. Rich from Sigma was always available to help explain the process and go over the installation and even the guys that did the installation were super friendly and didn’t leave my house a mess of muddy footprints

We recently had a Mitsubishi ductless system installed in our home & we just love it. The system cools our entire downstairs and it’s so quiet. For us it was a geat alternative to the expense of central air. Sigma’s entire staff especially Scott were so knowledgeable and professional. We would recommend them to any family thinking of installing any type of air conditioning system.

I will say first off I use to work for them when they first opened up. I was there service manager. It just didn’t work out. I can say one thing the owner always pushed customer service and fair prices. He would not put up with rude workers. I can not see this guy not caring and when I was there there was no min 1 hour charge above the diagnostic fee. The diagnostic fee is the same that I set 7 years ago. That shows prices are good there.

DO NOT USE THIS COMPANY! They sent me the most ridiculous quote with hidden costs that they added on to all the parts and equipment. Other quotes I received for the same parts and services were almost half of their quote. They are shady to say the least. Also, I called and they were discourteous and insulting on the phone.

Decent reliable service, but expect to pay $ 200 just to get someone to walk through your door ($ 89 «diagnostic» check and $ 89 an hour, 1st hour guaranteed…).
