    “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!

    “I am super happy with Northside and Kameron, and will not hesitate to call them again when I need HVAC service!”
    Kameron called me ahead of my appointment to discuss my issue and set an expectation for when he would arrive. He was right on time. Before he started any work, we talked about the services that would likely be required and what they cost. We also talked about what I was trying to accomplish with this service call. The call resulted in my unit once again operating normally for a price that I considered to be a great value!

    “Thank you, Josh!”
    Josh did an great job looking at the system and spending time both explaining and re-explaining to me. He went above and beyond by looking throughout the attic at our system.

    “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.

    “Exceeded My Expectations”
    We contracted with Northside Air to relocate 3 units at our home in Flower Mound. The 3 man crew took nearly 8 hours - so glad it was overcast for them. The finished job is so much better than the original install. We could not be happier. They did a great job cleaning up too. I don't have to worry about bits of metal or screws getting into my dogs paws. Thank You Northside. We are really pleased with the completed job. Thanks to the crew for being great while here!
