HOW TO CHANGE A HOUSE AIR FILTER

it is recommended that you change these every 90 days.. it's pretty easy to do and can really help with the efficiency of your heating/cooling unit. some units may have a screw where I had a lever.. if that is the case a flat head screwdriver is usually all that is necessary and it's generally just a half turn to unfasten it #ETPC #Etpcepictimepasschannel EPTC EPIC TIME PASS CHANNEL
