I had a problem with my old air conditioning unit where it was leaking Freon, and I was getting ready to go out of town. I made an appointment with Core Air, and I explained what was happening. The technician said if I wanted to move forward with purchasing a new unit, they would keep my house at temperature for the house sitter until I got back. They went above and beyond for me. I found a contract and we scheduled the appointment, which all happened very quickly. They were on time, professional, courteous, and did what they said they would do.
