What Our Customers Are Saying

Paul M.

“Fantastic service with professionalism. This company not only handles our current maintenance needs, but our recent purchase of a new A/C unit displayed to us how a company completes the task far better than expected. The work area was properly cleaned and the new unit was better than expected. We will always call Jacobazzi for all our A/C and Heating needs for our work needs, and future recommendations to family and guests.”

Jim M.

“Our new air conditioning system works great. The recommendation by tony to install add a high return has greatly improved the airflow and cooling efficiency in our home.”

Nancy M.

“I’ve been a Jacobazzi customer since 2014. They are always kind, professional and happy in their work. They live and work locally, making them a great part of the community. They are available to help at all hours but have always fit me in quickly during normal hours, which is awesome as problems only seem to happen during peak weather.”

“I’ve been using Jacobazzi for about 8 years now from checking equipment, full replacement on rentals units to the latest full AC/Furnace replacement with the new Evolution series. They do what they say, say what they do and they do it on time without any pressure.
Highly recommend.”
