His name is Lee - looks and sounds friendly but looks can be deceiving. My furnace broke down two days before our family was moving. He came to fix my furnace and charged me $158.00 for a Honeywell IS2 pressure switch and another $30.00 to get it. I researched online and found 10 to 15 websites selling it for $45.00. I asked him for an invoice and he said "I DON'T HAVE TO SHOW YOU ANYTHING!" I said 'fine' and asked him to tell me where his supplier was so I could check for myself to which he replied "THAT'S MY BUSINESS!" I had no problem with the labour and diagnostic charges but I suspected he was ripping me off for the part and pickup so I just wanted verification. I told him I would gladly pay for everything except for the part and pickup until he showed some proof. Instead of putting me at ease and showing me some semblance of proof, he used one of his real estate contacts to find the buyer of my house, he then contacted that person and their lawyer and threatened to sue them if I didn't pay. Because of the massive financial implications of not closing on time, I was forced to pay. This is the kind of thing this person is capable of. I can't say he deceives everyone but he deceived me and therefore you have no reason to think he won't deceive you. Look elsewhere.
