We obtained several quotes on a new air conditioning unit. Although MacKay wasn't the lowest price, we felt they would provide the best service. The salesman that visited the house seemed very knowledgeable and was very easy to contact for some follow up questions before we committed. Although there were some issues related to the install date due to a supply issue, the installation went well. The technicians protected the floor through the house with mats and did a good job. We're happy with the unit and the installation and would recommend MacKay Heating and Cooling.
