Cold day and furnace wouldn’t turn on. Called them 8 am and they said they would be out around noon, actually arrived 30 minutes early, which was good ’cause the house was getting cold. Very professional, checked a few things out, gave some honest answers to some questions I had about my unit, determined it was a clogged drain line, blew it out, told me what I could do to help prevent it in the future, and that was that. I was very happy with the service, and the price?! Unbelievable. I will definitely be recommending them to anybody that wants to listen.
