Absolutely professional installation. We had experience with this company more than 3 years ago, it was a very good service experience which we decided if ever we needed further AC/Heating support we would call on this company. We had our entire upstairs AC unit replaced, of course nobody wants this kind of expense, but the service call to assess our needs, the follow-up estimate and the installation was completely professional with a great deal of attention to detail. Completely informed through the entire install process, Jacob is very skilled and went above the norm to complete the installation to our satisfaction. We will definitely call upon Comfort Control for our future needs and will recommend to friends.
