I had this fellow come out to help me out and all i hear while i am at work is him being nice to me and taking advantage of my wife. he said the same thing to me that he said to the last reviewer. clean the coils. my wife wrote him a check and as they were walking out him and my wife had a few words. he ended up ripping up the check and throwing it at my wife. as he was leaving he shot her an obsene gesture. you can fill in the blank. i do not recommend using this tim horton fellow. oh and he is the owner and proud of it.
