hmmm, thing that sucks is that im driving up to cape cod tomorrow for the week so i need to make moves fast. Wish I had the time but am just going to bite the bullet and pay to have it done locally. Appreciate the offer! None the less I will need to be better prepared for next summer.
im in the same boat as you, I have a slow leak somewhere and end up spending $90 every summer to recharge. Its getting old real quick. Now that theres a heat wave here in the NE, wish I could just do it myself. No AC is killing me!
