Terrible experience from beginning to end. My attic air handler went down and needed to be replaced. The initial technician came out to submit a proposal, and he seemed knowledgeable and straight forward. He presented a price and I agreed to move forward, including paying an upfront deposit. On installation day, Abacus no showed and didn't call. I called and left a message and they rescheduled. This happened three different days!!! I felt like they were just trying to steal my deposit. After being lied to by two different shift managers, I was able to get in touch with the owner who gave me a full refund. Overall, not happy with the experience.
