Paul and his friend did an incredible job replacing our old HVAC system in a tough spot with a newer modern one. Paul was responsive to all my questions, professional and we are very pleased with the outcome. Don’t hesitate to ask them for advice or help!

We have a 30+ years old furnace that became malfunctioning two weeks ago, with the cold season coming up we were really concerned and had to replace it right away. Paul from Unisystems was extremely helpful and responded to our inquiry with a quote on the same day, and they were able to come in quickly for the installation. Work was done very well and everything tested out to be running fine. I would recommend anyone that needs furnace work to give them a chance and see if they can help your case as well.

Paul was great. Came out same day he got in touch with me. Explained everything and gave us a very reasonable quote, much better than the first contractor that come out, with a better furnace and a great AC unit. The crew that came out a week later were very professional. Went about their work quickly and was even nice enough to install the thermostat that I had purchased separately. Finished same day. I would definitely recommend for anyone looking for a new furnace or AC.

Super responsive and quickly assessed my needed without wasting any time. Got me scheduled and replaced my full HVAC system effectively. I’m back up and running with a new system at a competitive price.

Paul gave me a prompt, straightforward and competitive quote for a new central air conditioning condenser unit and coil to go with my existing ducted system and furnace. After several other quotes, I went with this company. They did an outstanding job. I finally have working central air and it feels *amazing*. Highly recommend this company. The crew was competent, on time, and everyone involved seemed trustworthy; also, no one tried to upsell me which I appreciated.
