Fadi of union air HEATING and COOLING responded to my call immediately and I was in crisis and was able to come to my home before 24 hours of passed. I suggest they are an excellent company.

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.

Excellent service will recommend price was awesome

Adeola Olulana

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.

I bought a new furnace from Union Air two weeks ago. Excellent service, perfect install and everything works great! I would highly recommend them!

Christopher Nantais

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.

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 AC Problems We Repair Every Day

Air conditioning systems rarely fail without warning. Small performance issues often signal deeper mechanical or electrical problems that reduce efficiency and lead to unexpected breakdowns. Our AC repair technicians are trained to diagnose these issues quickly and restore dependable cooling before they turn into costly emergencies. If your system isn’t keeping up, professional air conditioning repair can protect your comfort, energy usage, and equipment lifespan.

Signs You May Need AC Repair or Service

AC Not Cooling Properly – Weak or warm airflow often points to refrigerant issues, airflow restrictions, or failing components.
System Short Cycling – Low levels reduce efficiency and can cause your unit to freeze up or burn out the compressor.
Unusual Noises or Odors – Grinding, buzzing, or musty smells usually indicate mechanical wear or internal damage.
Rising Energy Bills – An inefficient system works harder than it should, driving up operating costs.
Unexpected Breakdowns – Sudden shutdowns often require immediate emergency AC repair to prevent further damage.
