    Union air was great! Quick quotes for two Furnace and AC units, and just as quick installations on 2 properties. Give them a call, get a quote. I think you will be happy.

    Great service and it was easy to work with them. I mistakenly sent funds to them instead of another vendor working at my house simultaneously and Fadi refunded me. That's some good naturedness.

    Our furnace stopped working and my wife started calling HVAC companies in a panic. The furnace was from 2003, so we knew it was time for a replacement. After reading reviews, Union Air stood out from the rest. When we called, the owner Fadi answered himself. He immediately put my wife at ease and came over within the hour. He explained everything clearly and honestly, without any pressure, so we understood exactly what was going on. We told Fadi that we were thinking of moving and didn’t want to rent a furnace. We preferred to pay in full, and he gave us a fair deal. We also added duct cleaning and a new thermostat. He gave us a clear quote, we agreed, and the work started Monday at 9:00 a.m. The team arrived on time and finished everything in about six hours. They removed the old furnace, installed the new one with updated piping and venting, cleaned the air ducts, and installed the new thermostat. Everything was done professionally and efficiently. Fadi took the time to show us how everything works before he left. The furnace worked great, we paid exactly what was agreed upon, and he told us to call anytime if we had questions. Fadi is professional, easy to talk to, and very straightforward. His team is just as good: licensed, hardworking, knowledgeable, and they kept the work area clean the entire time. Overall, an excellent experience with Union Air. Honest pricing, great communication, and quality work. I would absolutely recommend them to anyone needing furnace or HVAC services.

    Do I Need A New Furnace?

    At Union Air, we always get asked whether a new furnace is necessary. Furnaces have a limited life span. Like any mechanical unit with moving parts, things break down and wear out. Sometimes replacing a part or making a repair are enough. But there will come a time when you can no longer ignore the fact that HVAC system needs to be replaced.
