We had several technicians come to our home and "fix" our furance. For the past two years we continually had problems so gave Northern Comfort a call. It was a Friday night they came on a Saturday and quickly diagnosed the problem. It turns out all the "fixes" were far from it. We ended up needing a new unit due to it's age and "fixes" that were done before. But now we can rest assured we will not have to worry about not having heat. They are also very reasonable and thorough with a new installation of a unit.
