    “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!
