Timothy Off

The upstairs level of my house Stopped being cooled and the temperature went to 85°.At 8 o’clock at night I called Timothy Off to report the problem and see if somebody could come out to... help me. A technician was sent to see me and got here at about 8:30 o’clock in the evening and when he diagnosed the problem drove to his house to get a replacement part that he needed. He didn’t leave here till after 930 at night and solved my problem. Not only was he helpful but I was only charged a normal daytime right rather than an after hours rate which was a lot more expensive. I can’t commend him highly enough nor his company for helping me out in a verydifficult situation. I highly recommend using them and will continue to use them for any problems I may have With my HVAC systems. A great company with great personnel. I highly recommend more
