    “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!
    - Lisa
    “The Best in Town”
    Once again Northside delivers excellent service. Wouldn't use any other AC company.
    - Chris
    “He was extremely kind and professional, and we couldn't have been happier with the experience!”
    I called Northside this morning and they had a tech out to my home this evening! Al came to our home and took a lot of time explaining everything in detail, with pictures, in a way that I could understand it without a background in HVAC.
    - Casey F.
    “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.
    - Kim W.
    “$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
    “Back Up & Running”
    Francisco, my service guy, was timely, very polite, very helpful and did a very good job doing service on my AC units and electronic filters. Thank you!
    - Shannon
