My AC went out after 10yrs. I figured it would be about time for a new one. I called John Wayne, Airtron, lots of other big name businesses. They all came in trying to sell me a new unit without even looking at my current one. From $18,000 down to $10,000. I called Flo-rite Mechanical on a recommendation from a friend who swore by them. They came and physically looked at my unit by opening it up. The overall experience was a very pleasant ordeal. I wound up with a new unit installed at more than half the price of the other companies. Trust in this company as I have.
