Efficient, precise, and honest! Couldn't ask for better maintenence on my gas furnace.
Excellent service technician! He explained everything he was doing,and very clean and organized with what he was doing. I would definitely recommend Northern Comfort.
The AC wasn't keeping the house as cool as it normally does, so I called Northern Comfort Mechanical to have it checked. The technician went through the system, found an airflow issue, and made the necessary adjustment. He explained what he was doing and also looked over the unit for any other obvious problems. The difference was noticeable once the system was running again, and the house cooled more evenly.
Devin was just here and he found my problem immediately and corrected it. Noticed that my unit was clogged (I had no idea) and cleaned it. Northern Comfort is my go to for HVAC!
Top shelf service from start to finish arriving on time, diagnosed the problem with professional care and concern and provided detailed and honest options in order to resolve the mechanical issues in one of our main HVAC units. A pleasure to work with and our go-to should HVAC needs arise again at ACC.
