We were very impressed with Eric and the whole Acosta team, who came out to give us an estimate for a system replacement. They provided useful information, a detailed overview of the basic work with clear options to enhance.
Ultimately we went with a different company, largely because of our insurer wanted a straight system-to-system replacement at 2 tons.
A family member used Acosta for an installation and annual maintenance, and she also highly recommends. Thanks everybody.
