The only reason I am reluctant to put 5 stars in every category is that I feel the charge of $79 to just pull in the driveway is a bit outrageous. Then there are all the charges on top of that.
I have been a loyal customer for many years and have always been delighted with the professional and courteous people who come through my door to service my heating/air conditioning units. I have replaced both air conditioners and both furnaces since I have lived in this house and have always had a positive experience.
