  • Why Isn't My Home Getting Warm Enough?
    There are a few reasons why your furnace may not be warming your home efficiently or evenly. One of the most common reasons is a leak in the ducting. If there is a small hole or the ducting is improperly installed, it could leak out warm air and cause the air pressure to drop and the system then provides inadequate heating. Additionally, dirty filters will also cause a restriction in airflow making the system work harder. This can lead to a broken system, which is why regularly changing and/or cleaning your air filters is so important.
