In line with our Spring Cleaning HVAC advice, here is how you change your indoor air filter:
- Check the coil “condensate” drain: This drain, which is usually plastic, is located on the indoor air handler and is used to remove the moisture collected from the humid air in your home while the air conditioner is running. Since the coil’s temperature is lower than the ambient air, water from the air will condense on the coil and drip into the tray below. This condensed water needs to flow to a drain or the tray will fill up and flood the unit or potentially spill water out below your indoor unit and into your home which could cause a costly mess in a finished area.
