My AC Is Blowing Warm Air. What Should I Do?
Is your air conditioning system blowing warm air? Often, the problem is a dirty air filter or a blocked condensate line, issues that can be easily fixed by a homeowner. However, the cause may indicate a more serious problem, such as low refrigerant or a faulty compressor. Before calling a professional, try troubleshooting the problem yourself by cleaning the filter or condensate line.
How to Clean a Condensate Line
As the air conditioner runs, the condensate system collects moisture and routes it out of the house. A condensate line running from the indoor evaporator coil empties moisture into a drain pan, which sends the water to a drainpipe that transports it outside. A blocked condensate line can result in water flowing back into the system, which can damage components. Signs of blockage include water pooling around the air handler or your system’s inability to blow cool air. Blocks can occur from algae or other biological growth or dust or debris that enters the system.
Before you start, turn off the power. If you notice algae or dust, flush the tubing and clean the drain pan with a mixture of vinegar and water, plain water or hydrogen peroxide. Keep the cleaner inside the tube for about 30 minutes, then flush with plain water. Big clogs may require using a wet/dry shop vacuum to suck the material out. Alternatively, you can blow compressed air through the pipe to dislodge the block. Use moderate pressure because high pressure can damage pipes.
If this does not work, or if you are not comfortable with a DIY project, call your local AC Southeast HVAC contractor for help.
Importance of Regular Maintenance
