The air conditioning system is an essential household appliance that helps keep the home comfortable and cool all summer long.

In addition to changing out the air filters, you should also make clearing the drain line a regular part of your home maintenance. These a

1. Turn off the Air Conditioner

The first thing you want to do is turn the thermostat off and then shut off the power to the air conditioner. Some homes have a power switch near the unit, or you can shut off the power at the breaker. This will allow the water being dispersed to stop flowing and drain through the lines. It will also help reduce the risk of damage to the unit and electrical shock.

2. Locate the Drain Line Pipe

The drain pipe is usually located outside near the condenser unit. It is generally a PVC pipe coming out from inside your home. If you are not sure where it is located, check the owners’ manual or call an HVAC professional for assistance.

3. Remove the Cap from the Pipe

To access the drain line you need to remove the cap. It shouldn’t take any extra tools. Put gloves on and you should be able to remove the cap easily by hand.

4. Inspect the Drain Line

With the cap off, inspect the drain line for clogs, debris, or other signs of damage. If you have trouble seeing, you can illuminate the pipe with a flashlight.

5. Unclog the Pipe

You might find blockages in your drain line. These can include leaves and dirt, or even paper towels. Use a drain snake to clear out any clogs. It is a long, flexible metal cable you can attach to a power drill. This tool can clear debris quickly and help prevent future clogs. If you don’t have a drain snake you can try using a wire brush, but it will not reach as far or be as effective.

6. Pour in Some Vinegar

To help get rid of bacteria you can pour a cup of distilled white vinegar into the drain line pipe. It will help prevent mold growth, and mildew, and help prevent clogs.

7. Clean with a Wet/Dry Vacuum

If you were unable to remove the clog you can try using a wet/dry vacuum. This should clear out any water or debris still trapped. But, if a clog has been around since the last maintenance, it might be more difficult to remove.

8. Reconnect the Cap to the Line

Once the line is clear you can reconnect the cap on the drain line. It helps keeps debris out of the pipe and reduces the risk of clogs.

9. Turn on the Air Conditioner

Once the cap is back on you can switch the air conditioner back on at the circuit and at the thermostat. Then check for proper drainage to make sure it is running in proper working order.

These are the steps you can follow to unclog the drain lines of your air conditioner. If you are unsure or feel uneasy about this kind of air conditioning repair in Los Gatos, CA do not hesitate to call one of our HVAC professionals for an appointment.
