The serviceman was very knowledgeable and got my a/c up and running in no time. I had dealt with Air Care Systems before for the installation of insulation in my attic. There were two guys doing this service of course, and I requested and received one of the same courteous servicemen I had dealt with before. This let me know this company was a good and fair place to deal with, since it had been almost 5 years since the service and the same folks were working for the company. Haven’t seen that much here in Florida. I respect a company that treats their employees well enough, that they stay. They have won my loyalty as a customer.
