Supreme Air Systems

I woke up to a cold house on a day when the temperature was not going past 23 degrees. The heating and cooling company I normally deal with was booked up for six days. Even with a working fireplace, as a 70 year old disabled woman I had to find a way to get the heat back on. I found a listing for Supreme Air and even though they didn't have much of an online presence or many reviews I decided to take a chance. They were able to send a repairman out the same afternoon. On arrival I showed him that my Honeywell wireless thermostat was telling me that the heat was on when obviously it was not. He glanced at it and told me that he didn't deal with 'that junk'. My first instinct was to send him packing but I decided to let him have a look at the furnace. He said I needed a fan and he could go pick one up and install it within a couple of hours. He did this and I did hear the furnace kick on for a short time. When he came up from the basement I told him that my thermostat was now saying that I didn't have a signal and the furnace was not working. He said that was my problem, that he had jumped it at the furnace and it was working, and went to his van to write up the receipt. I basically just wanted to get him out of my house so I gave him a check and he stormed out. I called one of my tech savvy sons for advice and he told me to take out the batteries and put them back in. It worked! Isn't this something a technician should have known?
So basically, they responded in a timely manner, diagnosed the problem and made the repair. The cost was probably fair. But it was a very unsettling experience. The technician was defensive, openly hostile and was technologically challenged. He did not put his name on the bill.
