Hilliard-Dublin Heating & Air provided a very quick appointment as I scheduled my AC tune up. Matt, the tech was very professional, knowledgeable and thorough. I appreciated that the service cost was very reasonable (There was a "special" going on at the time I booked my service.) The tech called me about 30 minutes before his arrival to alert me to the time he would arrive. He donned booties so that his shoes would not soil my carpeting. He not only checked and serviced my AC very thoroughly but he also replaced my air cleaner filter with one he had on the truck. I immediately received an invoice via e mail and it listed all the items he checked and the results of his service check. I recommend this company very highly and also scheduled another service call for a second property I own.
