"I have been using East Coast Comfort for heating and air-conditioning for years and I have always been pleased. They installed a new system for us years ago, did it for far less than other estimates we received, and we have reduced our energy costs because of it."

"I contacted Unique Indoor Comfort, among others, to obtain a proposal for replacement of my furnace and air conditioning system. Unique took measurements off all the rooms (for sizing calculations), answered all my questions, and provided me with a written proposal with several system options ranging in cost. Some other contractors that had estimated this job had failed to either take measurements or provide a detailed written proposal. Although Unique did not have the cheapest proposal for this work, I felt most comfortable choosing Unique for the job because of their professional approach to the work, their ability to answer my questions, and their well-detailed proposal. The installation took one day. The contractors wore booties and put down cloths to keep my carpet clean when moving equipment. The installation went well, and I was satisfied with the quality of the work. The only issue I had was that the installation team forgot to install an upgraded piece of duct work. This duct piece only affected the efficiency of the system, not the operation, but it was included in the contract and touted by Unique as a benefit of their installation. After I noticed this and contacted Unique, they apologized and sent someone to install the upgrade within a few days. Overall, I am very satisfied with the system and the installation."

"The technician was on time and polite, and careful about our home. He determined that the freon was gone in our system and tried to give it a freon boost. It was unsuccessful and he said that indicated a leak somewhere in the line between the basement and the outdoor unit. He suggested a new unit since our unit is 7 years old and was a base model. We discussed units and he suggested that he would get in touch with Mr. Dibiase who would be better able to give us the information we required. Mr. Dibiase called us and gave me some figures over the phone, but I wanted to have him come out in person and could not schedule it for several weeks because of my own commitments. He was very polite and helpful on the phone. Several days later, my husband recalled that he had added our heat pump to a Sears Service Agreement that allowed us to add existing appliances less than ten years old to our service contract for the Kenmore applicances we already had. We called Sears and they came out and were successful at adding freon. They suggested we call again at the beginning of the AC season to have them evaluate the system. This does not mean we won't use DiBiase, but we were surprised that Sears was able to add freon and the Dibiase tech was not. Perhaps we just didn't understand fully, but we will give the Sears service contract another try before replacing the entire unit.

"I can't say enough about the team at Old Skool HVAC. I learned of this organization from a close friend who had work done and recommended them. Frank is a great guy. On time, professional, knowledgeable, and his team is a reflection of this as well. They were always on time, on schedule, clean, and very personable. They finished our job a little early, and during the first heat wave just about week or two ago, our house never felt better. Great service, quality, and pricing. It's funny, with central AC, you never really know that it's hot out until you leave the house and come home. It's during this first transition that I realized how quiet and effective of a system that was installed. If you are looking for any form of HVAC work in your home of business, I'd recommend contacting this group of professionals."
