Furnace Filter Maintenance
Your furnace filter needs to be replaced at minimum every 3 months.
Your home has a 16X25X1 filter at the furnace. To replace, remove the existing filter and insert the new filter with the directional arrows on top of filter facing towards the furnace.
In addition, your home may also have a 14X20X1 filter located on the air return in your living room. To replace this filter, remove the return cover and remove the existing filter. Insert the new filter with the directional arrows pointing inward.
