Furnaces can be intimidating, but that doesn’t mean you can’t
take an active role in keeping yours well maintained. Knowing when to
fix a problem yourself and when to call in the professionals is key. Here’s
a guide to some common furnace problems you can fix on your own, and some
more complicated issues best left to the experts.
Air Filter Replacement
Furnaces rely on air filters to keep dust and other contaminants out of
essential components. When filters get dirty, it becomes harder for the
furnace to keep up adequate airflow, lowering its energy efficiency and
raising your heating bills. That’s why experts recommend
changing your air filters
at least once every three months. High-efficiency pleated filters with
electrostatic charges are your best option. Look at your instruction manual
for proper replacement techniques.
Cleaning Your Air Vents
Air vents allow hot or cold air from your HVAC system to reach all areas
of your home. When they’re blocked up with dust or other debris,
it can keep your system from running at peak efficiency. Be sure to dust
and vacuum in and around your air vents at least once a month. If you
notice mold around the vents during your cleaning and inspection, call
a professional to have your ductwork checked for mold or other contaminants.
Checking Your Thermostat
Far too many homeowners have called a technician in the winter only to
find that their thermostat was set to “cool.” That’s
why it’s always best to check your thermostat before assuming that
your furnace has a problem. You’ll want to check if the temperature
is set properly, whether your model has a fresh set of batteries, and
if a programmable model is displaying the right date and time. If there
is something wrong with your thermostat and you can’t fix it with
new batteries or a few button presses, you’ll want to have an HVAC
repair technician help you out.
Problems Best Left to the Professionals
Even the handiest homeowners can’t solve every HVAC problem. If you
find that you can’t troubleshoot a furnace problem on your own,
don’t hesitate to call an expert. This is especially important for
problems and routine maintenance inside your HVAC unit, such as issues
with blowers, gas supply valves, and burners. Of course, if you ever suspect
a gas leak, call your gas provider or a qualified HVAC technician immediately.
