We called Gresham Heating an Air Conditioning Inc. because we have a service contract with them. Our heat pump is getting older and has started breaking down. After I couldn't get my emergency elements to come on in the furnace, we called Tyson and he never called back. I eventually got the elements to come on. We called on a Monday and they said he would be out on Thursday. Tyson even called us to confirm our appointment for Thursday. Thursday came and he didn't show up. We called the office and the girl said we weren't even on the schedule. We asked her to call his cell phone and find out what was going on. After all that, he finally showed up at the end of the day after he finished all his other appointments. We aren't very comfortable relying on this company for our heating needs when it's only one guy doing all the work.
