Sigman came out today and installed new air ducts into my 1870's house. Not an easy job. But their techs were very professional and meticulous. They did a great job of making everything line up perfectly. I would recommend them for any heating, air-conditioning job you have!

Had a concern with my upstairs unit (in the attic) that had a full clogged drain, also helped me install a new thermostat (Ecobee 3L) as it needed a common wire to the thermostat. Randy was awesome! Thanks for the quick service today!

I had Sigman come out to do maintenance and attach a wire adapter to our HVAC in order for us to install a new electric thermostat. The guys stayed extra to take care of a few issues they came across. They did a great job.

Sigman's team installed a multi-zone, multi-phase heat pump in September. The installation team was topnotch. Our sales contact, Craig, walked us through the process and recently worked with us regarding a thermostat wiring issue. Cannot say enough good things about our experience. Now to enjoy lower winter energy bills!

Yes their are great people in this world! A BIG shout out to the gentlemen from Sigman Heating and Air Conditioning who showed up at my front door this morning with my husband’s wallet. He found it on the street at the corner of Cedarwood Trail & Frank Scott Parkway! Apparently hubby left it on top of the car and this honest man took time out of his busy day to drop it by our house!
