    “Awesome!”
    Want to say thanks so much for a job well done! I’ve used Northside now for a couple years and Your service is impeccable. Anytime I’ve had emergency issues arise I’ve always had an almost immediate call back. Chris (svc tech) has been taking care of us for a little while now and he’s been nothing short of great. He’s professional, courteous, and knows his trade very well. He demonstrates a very real concern for correctly identifying the problems and addressing them correctly. As long as I live in the Denton county area, Northside will always be my HVAC service provider. I promise you won’t find a better group of folks around. Thanks again guys/gals!

    “A Hidden Jewel”
    This is the best company in the DFW area. They are a hidden jewel. The staff is professional, honest and not on commission to sell you things you don't need. Other companies should follow their business plan.

    “My Go-To!”
    I have had Northside Air Conditioning maintain my systems for almost three years and have been very happy with their outstanding service. Michael, the service technician, is always on time, thorough, and very professional. He is the best!
    - Donise
    “Customers for Life!”
    We have been Northside customers for over 10 years. We would never call anyone else. We constantly refer this company to others. John D. is as good as they come! He is always professional, thorough, punctual, and informs me of what is going on with our systems & what we can expect from them for the upcoming season. Additionally, he recently offered to get warranty information for some of the equipment in our new home. He called me back with the info within a day as he promised. This level of service is amazing! Customers for life!
    - Marcey
    “$405”
    Mike, the technician, was very, very good. He diagnosed and determined the problem. He had to spend a long time doing that, and the weather was bitter cold!
    - Stephen and Jane Noble
    “Excellent experience with Northside Air Conditioning”
    One of our AC units went down on a very hot Sunday afternoon. I called several companies that claim 24/7 response time but all were not able to schedule an appointment for 3 to 4 days. I finally found Northside Air Conditioning on line and called. A technician was at my house in about 3 hours and fixed the problem immediately. I found Northside Air Conditioning to be very professional, efficient, courteous, honest, and very fair priced. I will most definitely use Northside Air Conditioning again and will highly recommend the company to friends and neighbors.
