About the Air Filter
The air filter is a critical part of heating and cooling the home. Not only does it filter the circulated air, it also helps keep the air ducts and the furnace coil from clogging up. Over time as the air filter collects dust and debris, it can start to produce strange whistling or low humming noises. Check and replace the air filter at least twice a year, more often in dusty/dirty environments or if there is a pet in the home.
