I almost hesitate to write a positive review because I'm worried that by the time I'm ready to get an A/C installed, CJ will be everyone's HVAC guy and will be booked out 6 months in advance haha.


The first time he came, it was to inspect my furnace and diagnose a weird goop leaking out of a duct. He tried really hard -- he moved my fridge, crawled through stacks of boxes and a pile of dog hair to remove vent covers, used some fancy camera. In the end we couldn't figure out the source, but not for lack of trying on his part.


Then a couple months later I had him come back and install a new furnace. He was really clever with how he routed the water run-off (I didn't even know furnaces produced water?!) and left my basement cleaner than when he found it.

Bought a house with an older AC unit and didn’t think the condenser unit outside worked. Had Northland Air come out and inspect my whole HVAC system. Pointed out a lot of great tips and tricks to optimize the homes system and also got the AC working in no time! Awesome experience and will use for all future work. Thank you!

CJ replied within a few hours of my inquiry and was able to quickly come to our home to identify and fix the issue with our AC. He was professional and courteous. The cost was very fair and appropriate for the work that was done. We'd certainly work with him and the company again!


-Gabi H.

★★★★★

CJ has been amazing to work with. He worked on our boiler and he was very quick and efficient. Would definitely recommend him to all my friends and family. Thanks CJ for everything you’ve done for us!

CJ’s work was very complex, on an old system and an old house. We first installed mini splits. They are a lot more expensive than people think that they are, but CJ‘s price was significantly lower than other local competitors. He installed them without difficulty, and they work amazing- the rebates and the tax benefits were also a plus. Because of his work on the mini splits, when our furnace went down, we had him replace the furnace. It was another complex project, and he did it very professionally, taking time to figure out the proper way to install. He has a knack for building trust, being responsive, and explaining what he is doing. He is our HVAC guy from now on.

We hired Northland Air to install a new natural gas furnaces (instead of our old fuel oil beast) this fall. With the early spring, we had them back out to install a new air conditioner at our house. The furnace is working wonderfully and CJ was very professional and timely, making sure to thoroughly clean up after himself each day that he was here.


We will absolutely have Northland Air come out for any of our future HVAC needs and would recommend them to our family and friends!

Great company to do business with !! CJ came out at 6 o’clock at night to fix a plugged drain line on my mini split unit. While he was here I had some questions and was very knowledgeable and provided options for my concerns, I definitely recommend using Northland Air and they will be the first I call for any issues I have with AC or heating


-Joseph D.

After reading reviews, we called Northland Air. CJ immediately answered the call and was here in 30 minutes. He was able to do a temporary furnace fix and will return later in the week. We were very happy with the quick response and professionalism.

We had a new furnace and ac unit installed. Quick and professional service!


Very thoughtful with respect for the homeowner and the home. Strong work ethic is shown in the completed job and all through the installation process. Will be recommending to everyone !!!

CJ made it to our home in less than 24 hrs on a weekend to diagnose a malfunctioning central air. Made time to come out early the next week to make the repair. It was important that we got it repaired quickly because the weather was warm and leaving the windows open during air quality advisory was concerning with a newborn in the home. His promptness was greatly appreciated! He explained everything throughly, fair price, friendly and professional. Will be using Northland Air again and recommending to others!

I was looking for an expert opinion on how to proceed with servicing and optimizing my furnace. He was wonderful, giving me both advantages and disadvantages of the approaches he suggested. He was truthful and very knowledgeable about new and old technologies out there for optimizing energy. I would definately want him to service my furnace every year. The best part is that they are local and dependable.


-Michael N.

Wow! Cj ,the owner, was very knowledgeable on ever question that I asked. He was quick and efficient. Even though I didn’t need much done he took extra time to make sure that my system was running correctly and efficiently. He also gave me some great tips on how to maintain the indoor and outdoor units. I highly recommend Northland Air for any of your heating/cooling issues or new installation. Top notch work, Cj! Thank you!


-Jonathan B.

Northland Air came and conducted preventative maintenance on my furnace the other day. They found a bad exchanger and took the time to go out of their way to take it out and show proof of a crack. We went to them for a new furnace install and the whole experience was very pleasant.


-Deron W.

★★★★★

Northland Air took the time to walk me through the options after my furnace failed. Got us up and running with a new unit and installed AC as well and we are ready for the muggy season as well as the long cold. Very happy with the results.


-Michael S.

Cj was great to work with, he took the time to explain the issue with our AC and go over the options with me. He was incredibly transparent and patient. Work was done in a timely and efficient manner. Cj is my new first to call with all things HVAC!
