Leaves are falling and mornings are getting crisp.  Soon we will be switching to heating season.  If you haven't yet had your furnace serviced for a couple seasons consider the following.  Having a professional inspect your home's heating system can not only ensure the system is set up to run as efficiently as possible doing things like adjusting gas pressure, but we can also find safety problems that could put your family's health at risk.  Improper venting, improper combustion make up, fresh air issues, and rusting out metal venting are all common problems found on most tune-ups.  It's always important even if you do not have a tune-up please make sure carbon monoxide alarms are on each floor of your home and working properly!
