Northern Air Heating & Cooling is a wonderful company! When we first needed them this Winter, Todd immediately responded on a Sunday and stated that they would be at our house on Monday morning to get us heat. They provide quick, efficient service at reasonable prices.
William Sutton
I can’t say enough about how much my family appreciates the father-and-son team of Todd and Adam at Northern Air. This level of care, professionalism, and genuine kindness is rare. We are truly grateful to Northern Air for their outstanding service and commitment to doing the job right.

Our unit was literally on its last leg, I called him and they put a new unit in super quick & at a reasonable price. I can’t say enough about how helpful, knowledgeable, down to earth, and understanding the owner & his son are. If you’re needing HVAC work done, call them.
