Another common problem that people face with their furnace is when it is not heating sufficiently. This may be due to a blocked blower or a dirty filter. These issues can be fixed easily by cleaning your furnace. You can do it yourself by referring the manual or call a HVAC professional for servicing the unit. Sometimes you may face a problem where your furnace switches on and off even before heating to the set temperature. This can be due to a clogged blower or filter. It can also be due to a dry motor. With the help of a vacuum cleaner you can clean the blower and the filter.
