A simple, sometimes ignored and avoided maintenance issue homeowners sometimes fail to deal with on a regular basis is the changing of air filters in a forced air heating and cooling system. Failure to regularly maintain your filter in your duct work could lead to expensive and unnecessary repairs. You would be kicking yourself when you pay out to your technician the price of a new capacitor or a new squirrel cage blower motor or worse. A new system all together. Hard to believe that a simple 3 dollar filter could cause such expensive repairs but this is the case. It is always best when you change your filter, to have a supply of 5-10 filters available to get you through the year. More if you are doing remodeling and creating dust in your home. Locate your filter rack every time the same month and do an inspection of the filter with the system off. Best not to do this inspection with the furnace running or able to turn on at a moments notice. A kill switch next too, or on, or at the thermostat should be placed in the off position. Remove your filter. Take notice of any directional arrows for air flow at this time as it will be very important to place the filter or it’s replacement in the same direction. Hold it up to the light if it is not obvious that dust particles etc. have clogged and impeded the ability of your filter to do it’s job. If it looks clean, come back in a week and check it again. If it’s ready to be replaced do so at this time. Replace any doors or covers at this time and put the furnace power switches or thermostats back to the on position.
That’s it. Once a month inspection and replacement will go a long way to guaranteeing you years of trouble free operation of one of the most important pieces of equipment used by you and your family to maintain comfort through out the year.
