My company has had a contract with this company for around 7 years now to do our quarterly maintenance on our a/c and heating and they recently called to tell us they were dropping us as a client because they didn’t feel like driving out to all of our locations anymore… with no warning! I’m disappointed that a long-term relationship seemed to mean nothing to them and they didn’t mind leaving us in a lurch. Now we’re scrambling to find a new a/c and heating company, who will have to come out and look at our systems to figure out what we have, since Hi-Tech didn’t offer us any recommendations when asked and didn’t give us any information on our systems that we could pass on to a new company. I will certainly update this when I get the new company out and they can tell us whether Hi-Tech was even doing the maintenance we were paying for.
