I believe I have been cheated. My AC was not cooling. I was quoted $95 for a service call. I was charged $450. There was no repair made, only the addition of freon. The amount of freon added, according to Bryant Heating and Cooling, was probably about 3 pounds. A 30 pound bottle of freon22 sells for about $450. If 15 pounds had been added, the fair charge should have been around $310. Thus, the overcharge of about $140 or 45%. I have discussed the issue with Bryant but they are unwilling to reconsider. If you use them, be certain to get an absolutely firm quote before they begin service.
