My furnace started working sporadically...sometimes it would work fine, other times it would just blow cold air or not do anything at all. \r
I called several H VAC businesses to find them all booked up through the holidays, some even sounding annoyed at my request for service. Then I called Controlling Systems. Gus answered with a friendly and professional voice, listened to my concern, and scheduled me for later the same day. He was able to arrive one full hour before that time after a call to see if I was available and had a new sensor installed, the dust blown out, and everything cleaned up before the original appointment time!! The furnace works great now and both grandma and I are most appreciative! I absolutely recommend this company!
