Reviews and Testimonials

See What Our Customers Are Saying

“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
“Definitely a great experience.”
Josh was amazing! He was very friendly and professional! He was respectful of waking into all my classrooms. Made all my staff feel comfortable.

- Lisa H.
“The Best in Town”
Once again Northside delivers excellent service. Wouldn't use any other AC company.

- Chris
“Best Service Ever !!”
Our air conditioner failed last night and we called 4 companies to come out, last night if possible. In my message I requested to please return my call to let me know if that was possible, or if I should continue my search. The ONLY company to return my call was Northside, and they not only came out and fixed our unit late at night, but were courteous, professional and called when they were on their way to let us know when they would arrive. Thank you so much, your efforts were much appreciated!

- Terry and Lynda Hall
“Above & Beyond”
Excellence deserves recognition and reward. The team of employees sent to install my HVAC unit no doubt are a product of your leadership skills! Well Done to Tony R., Jamar, Jason & Tamarus. This experience was more rewarding than buying a new car! All my referrals will go to Northside AC! Thank you Tony H. for selling the anti-sales lady! You'll go far! Today I'm living the dream with my Accu-filter!
