I get the same thing with HVAC and it gets miserably hot here in Va. so come July/August I`m everybody`s best friend. I have people call me I haven`t seen in 35 years....." hey John, I hear you work on air conditioners"? .........and I`m like "who, Greg?...Craig?......oh yeah, Craig from high school, sure, I remember you" ?. Lol!!! Sometimes I can get out of it when I tell them the price of Freon now. You have to look at it like this, it`s a chance to make a buck, a friend, or build favor equity, and besides isn`t it better to be wanted for something than not be wanted for anything.
