    “To The Rescue!”
    Great service! We came home on the Sunday of the Independence Day weekend and our AC wasn't working. The technician was to our house within an hour and able to fix our unit. He had a great attitude even though it was a Sunday of a holiday weekend. He also helped us with a few of our filters. Thank you Northside for keeping us (and our dog) out of a hotel!

    “Very Thorough”
    I highly recommend Northside Air Conditioning. Chuck Parker promptly reviewed our broken system and gave us several upgrade options. Within two days they were here to update our entire system, inside and out including the furnace. The techs, Spencer Murray and Jamar Johnson, were very professional. They were hard working despite the weather being in the high 90's. They took the time to vacuum any debris that had fallen on the floor. They also inspected every vent in the house and found one vent had a quarter size piece of insulation and promptly removed it. We were very pleased with the service provided by all employees at Northside Air Conditioning.

    “Great company, great people, great work, great product. These people are the real deal.”
    Our home central air conditioning system died in he middle of July and we needed to get a replacement. We did a full due diligence search considering all the options available. Please allow me to save you similar time by telling you not to bother and just go to Northside Air. I will tell you that these guys will not be your cheapest option in town (they will be very fair though) but come on, you are talking about buying a system that will control your home environment, every day of every year. Do you really want to be cheap about this or do you want a really good system. These guys were great if I can understate their value. When I inquired they sent Chuck out. He did a full analysis of the home and then sat down and explained all the whys and whatfors. He never pushed us to buy any extra whistles or bells, just laid out our options. When the guys came out to install, they just did an awesome job. From start to finish, their work was clear, accurate and spot on. What a pleasure to work with these guys. Five seconds after they left, you could never tell they were here working, thats how clean they were and how professional their installation was. Great company, great people, great work, great product. These people are the real deal.

    Louis arrived right on time then identified and fixed the problem very quickly! I was thrilled not to have wait around all day for my service. He was very knowledgeable and thorough, and I appreciated that he took the time to explain what was wrong and how he fixed it.
