My AC was not blowing cold air. On 8/15/25 I called Pro Air for service. Mark came out that day and…read moresaid I needed freon. He said the compresser?? would need to thaw, so he was leaving on another call and would be back. On his return he stated the AC would need about 3# of freon at $150 per pound. Okey done at the cost of $589. with "working better". After using it 9-10 times that fall I covered it for winter. On 4/14-15/26 I turned it back on, fan worked but "NO AIR". Called Pro Air on 4/17 and told they would get back. Have not heard from Pro Air by the 22nd (Wonder why, must not need the business) I called back and got Mark, I explained "NO cold air'. He said he would come out but there would be a service charge $139. I ask why he would not check the lines for leaks? He said that could take hours??? Not very good customer service, like a money grab? Getting a new AC but FOR SURE, Pro Air will near see it. In the end Pro Air losses.

Oh, and since then our chimney cap came off and was on the ground. It was rotted clean through! Guess it wasn't a roofing issue after all! If a company won't return your call when you are trying to pay them what will they do if you have a problem and need their help ?
