Rob R
Been working with Bill D for a couple years at a our home and my mother's home. Recently had the pleasure of working Matt at our business. I can't tell you what a relief it is to have such a trustworthy team to work with. These two gentlemen are absolutely top notch. Highly recommend!
Denise H
Bill, God bless him, came out on a 100 degree Sunday and fixed our A/C. He had great communication, was on time, and knew exactly what to do and saved the day! I appreciated his great attitude and kind spirit as well. The price was reasonable for a weekend visit. We will definitely use them again!

Northern Air installed Central Air in my home in Fall 2021 (I did not have it). I also wanted a high efficiency furnace since my furnace was over 23 years old, even though it was still working. I got bids from 5-6 other HVAC companies. None of them were interested in installing a high efficiency furnace, even the companies recommended by “Efficiency Works” One company would not even install Central Air because they could not figure out how to install in my crawl space. Northern Air were great, efficient, neat, and had the best prices as well!

Mindy M

The technician that came out, Ronnie, was absolutely wonderful. Extremely professional, quickly installed the new thermostat, and even showed me step by step how to set up the scheduling option on the new one.

Every time Northern Air sends someone out, the work is always done quickly and their prices are definitely more reasonable than most of the companies in the area!

Great company!! Our daughter’s furnace went out yesterday on the coldest day in the past 30 years! Not only did they respond promptly and replace the furnace today, they brought her space heaters last night! I highly recommend this company for their ethical practices, fair prices and commitment to our community! Thank you Nick, JJ and Brett for your help!!
