Jim Lawson2025-03-17Trustindex verifies that the original source of the review is Google. Service First Heating and Air came to our house today to install a new unit. They sent plenty of service people to install, they ran all tests, taught us how to use the new, etc. They were all very polite and seemed to know exactly what they were doing. They are probably not the most inexpensive but they are certainly not the most expensive, what they are, are qualified technicians who did an excellent job.
