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.
