See What Our Customers Are Saying

“Reliable & Dependable”
I have used Northside for over 7 years they are reliable and dependable.

- Kathy
“Great Service”
Got a courtesy call letting me know Andy was on his way. Very careful in keeping my home clean. Explained exactly what was needed to repair my HVAC unit. Worked hard to get me up and running. I felt it was a fair price for a job well done. Northside is my go to HVAC company.

- John
“Price was Fair”
“An excellent job!”

- Tara T.
“Very pleased”
It takes a lot to impress me; the customer service representative who answered the telephone/set up the service call was most pleasant and most efficient. I requested Chris to make sure our heater was in good shape for the coming winter. He has serviced both our heater and air conditioner in the past. Can not say enough good things about his professionalism, work ethic and expertise. I will continue to recommend Northside to my neighbors and friends.

- HBM
“Josh was very helpful!”
He even helped fix a decoration within the classroom that I couldn't reach. He was super friendly and even answered some students questions as he worked.

- Carlos H.
“These are the folks you want working on your HVAC systems”
Every time I meet more of the Northside Air folks I constantly become more impressed. Bobby and Jerry (the owners) are great but now I have met Michael and Tony who are both excellent. Northside Air did all the HVAC in my new build in Flower Mound (5 units with 20 tons of air) and it has turned out great. I liked them so much I had them do all new AC, furnaces and thermostats in my old house in Carrollton (3 units with 11 tons of air). I am an engineer so it does take a bit to impress me on mechanical equipment but the folks at Northside Air do so every time. These are the folks you want working on your HVAC systems.

- David Lewis
“Josh did an amazing job!”
Very professional and easy to work with!

- Melanie W.
“Honest and FAST”
Thanks to Luis for the great service. He was availalbe earlier than my appointment and he called to let me know when he was arriving. He was prompt and more importantly, honest with my repair recommendation. Would highly recommend Northside.

- Michael
