DIY AC Repair Tip #3: Did you know that when your air conditioning system runs in the cooling mode it produces water? This water is a created when the warm air in your home passes across the cold evaporator coil. The condensation created is then collected in a drain pan and drains through a small PVC pipe. If this PVC pipe becomes clogged from dirt, dust, algae build up, or rust, the drain pan overflows. This overflow water could spill onto your sheet rock and cost you hundreds of dollars. Luckily there is an emergency drain pan that is located under your evaporator coil to help prevent this overflow water from causing damage. This emergency pan drains outside of your home, usually in front of a window that you would notice like a kitchen window or bathroom window. If you see this water dripping do not hesitate contact us to resolve the problem. Left unchecked, this drain line could back up and cause serious damage. If you are unsure of where your emergency drain line is located, ask your HVAC technician to locate it for you during your next AC maintenance appointment. We are standing by to answer any of your questions or provide any assistance you many need.
