Had been using them multiple times. Recently the service has been bad. Had them out twice for the same problem and had to call a different company to try and fix it. If you are planning on using them, I say try to fix it yourself. You will probably get the same results. When we called to discuss why our bill the second time was so high, we got a response of "we have to keep the doors open, that's why it was so much". I really doubt if a business like heating and cooling has struggled during the pandemic. Poor excuse for a company.

One call and a tech came right out and got our heat working temporarily. Next trip, a new furnace was in and running before dinner time. Prompt, professional and efficient.

Critical: Responsiveness The thermostat they installed is not working. I have called and emailed Denise multiple times and they are no longer responding. I just want my new A/C system to work! Sometimes things dont work, but not responding to a customer is unacceptable. Services: Install AC, Heating system installation

I am in the process of opening a complaint with BBB Better Business Bureaus since they absolutely refused to acknowledge my grievance. PLEASE stay away from Jacobazzi! I wish I can say they serviced my furnace superbly, however, Denise, the owner's wife, who was quick to take my money never returned any emails, nor voicemails, not to mention issuing a justified refund for an expensive job ~$1k, not even an apology!
After a botched up repair by Jacobazzi the firefighters had to evacuate my building on a Saturday night due to life threatening carbon monoxide release. It cost additional time and money to properly fix the furnace by a licensed contractor. Do not hire Jacobazzi, they NEVER want to hear from you once they get paid unfortunately and do not take any accountability.

Jim, the Jacobazzi technician who came out to fix my air conditioner today, could not have been more professional and courteous. I don't have a clue how any of this works, and he explained EVERYTHING to me in a way that I could understand so I knew exactly what he was doing and why. I have used Jacobazzi before, and I will be a lifelong customer of theirs because of their prompt and professional service! Thank you to Jim and Jacobazzi for another excellent service experience!
