Pleasant and professional service. Explained all questions
It was a pleasure to meet with Tony Fiore today to review options and pricing for the replacement of our attic AC unit.
For the past five years we have been trying to figure out why our heat pump and oil furnace backup is not synching properly. We have had many technicians from at least 3 different companies (including the one that sold us the heat pump!) come out to try to fix it. The team at DiBiase was the first to figure out that the thermostat was the issue. From the communication with the office staff, to the technicians who came out, this was a great experience for us.
DiBiase is definitely the go to for heating and Air Conditioning services! Punctual, efficient, clean and respectful of home owners home! Dan was very helpful and went beyond the scope of service by helping me troubleshoot our second unit. Thank you!!
