 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. Excellent service! Prompt response from owner. Workers were pleasant , polite and did an outstanding job on the install of my outdoor furnace and air unit. They even worked in the snow but got the job done efficiently and took care of everything! I highly recommend this company. Best price as well! I’m very satisfied with everything. Sitting nice and toasty warm once again! Thank you Fadi and gentleman! Thank you!

Common HVAC Failures We Resolve

Your heating and cooling system is a complex machine that works 24/7 to maintain your comfort. Minor glitches often act as early warning signs; ignoring a small issue today can lead to a total system failure tomorrow. Proactive repairs not only extend the lifespan of your HVAC system but also keep your monthly energy costs from skyrocketing. If you notice any of the following, our team is ready to provide a precise diagnostic.

Restricted Airflow (Dirty Filters/Coils) – Clogged filters and plugged coils force your system to work twice as hard, leading to overheating and premature part failure.
Refrigerant & Fluid Leaks – Low levels reduce efficiency and can cause your unit to freeze up or burn out the compressor.
Mechanical & Blower Failures – Issues with the blower motor or belt can stop air circulation entirely, leaving your home uncomfortable and stagnant.
Thermostat & Electrical Malfunctions – Faulty wiring, worn connections, or outdated thermostats cause inconsistent temperatures and system “short-cycling.”
Ignition & Gas Supply Issues – Problems with gas valves or pilot lights are safety hazards that prevent your system from generating heat when you need it most.

Don’t wait for a total breakdown. Addressing these fundamental mechanical issues promptly ensures your HVAC system runs safely and reliably. Contact Union Air today for a professional inspection and long-term peace of mind.
