Here is the vertical cedar fence my hubby built (with my design, lumber shopping and staining help - I'm useless with a hammer though) to cover up the two hideous air conditioning units gracing our frontage. He's awesome! I'm happy. We left lots of air for the AC units to breathe so hopefully its fine.
Cleaning the Evaporator (A-coil) On the inside of your home in the furnace is the evaporator -- also known as the 'air-conditioning coil' or 'A-coil' because it's shaped normally like an 'A.' The A-coil must be kept clean as air from the blower must be able to freely flow through it during both the heating and cooling season.
