sinning air conditioner

When we moved into this house it had the heaters in the ceiling. Seems silly to me since heat rises. Also I didn't understand how the house didn't burn down. I know Barb used it when she lived here, but I just couldn't bring myself to use it.
Justin's mom/family owns a air conditioning/heating supply company in Hawaii. His mom talked to one of the distributors that had watched Justin grow up, and he gave us a complete top of the line system FOR FREE. Justin's mom worked out some kind of a deal for the labor, and in the end we didn't pay a penny. So let me first say that we are very lucky and blessed to have this system at all. But I am going to complain about it for a minute. :)
We got it installed a few years ago, and everything was great at first. Then I think we had problems with the heat part of it followed by problems with the air conditioning. We are now onto the air conditioning problem again. It doesn't work at all. I would be fine with having a house that gets up to 85 degrees if I knew it was just something we had to deal with. But the fact that our system is completely capable of producing cold air and just doesn't do it makes me really frustrated. So this got me thinking that I wonder if God ever feels this way about us. He gives us specific giftings in our life that he wants us to use to better the body of Christ. And when we don't use it does he look at us with the same frustration that I feel for our air conditioner? I think it is very realistic that he would.
