One time "John" answered and I told him I was interested in an HVAC maintenance and service contract. He rattled off some numbers and promised to email them to me that night. Never got anything. I then called that number over and over, leaving messages that again were never returned. Finally, a woman answered and explained that she was in a front office and could give me no info (??) about service contracts, but she said if I called 800-921-0392 an answering service would take a message and forward to someone who would call back. She also promised me that John would send me the promised info that day. Not. So I called the 800 number and left a message for someone to please call me. Nothing. I give up. Too many other HVAC companies that care. I wonder how if they respond to customers needing emergency service.

Its obvious the technicians are quite well versed in trying to get money our of people like me. They charged over $4000 to fix my air conditioning in 2024, then in Spring 2025 they're tech said the system was fine and nothing was wrong, OH, and why don't you spend over $1000 on This part for your AC to make it work better? Spend more money please. Come June the air conditioning does not work at all. Even if I had spent the money it wouldn't matter. They obviously don't want anybody's AC to work, they just want more moola. In June, my card number needed to be changed. And Top Flight wasn't sucking an extra $20 out of me and my 82 year old mother for six months. Now they sent me 6 invoices, SIX, saying I owe them $120 for NOTHING, just so they can hit us up for money when they stop by. Forget that and forget "Top" Flight, they are on the Bottom and sucking the scum out of the bottom of the pond.
