“Would recommend 10/10.”
Kameron was great and very helpful. Professional service.

- Bryan B.
“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.
“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.

- David C.
“Very Pleased”
Great organization, prompt and professional. Luis is a great tech, very knowledgeable and extremely personable.

- Kristopher
“Al was amazing!!”
He was very nice and professional, he took pictures to show us what was wrong with our AC and thoroughly explained everything. Make sure to ask for Al! He was very nice and helpful!

- Breanna R.
“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.

- Bill
“Quick & Easy”
Jeremy was very professional and completed the maintenance service on our system in a timely manner.

- Lucious S.
“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!
