Fixing Air Conditioner/Heater Dripping Sound Fixing Air Conditioner/Heater Dripping Sound
Often the cause of a dripping sound coming from the air conditioner heater unit is due to a lack of maintenance and a fix yourself job can save some money if the situation is addressed soon enough.
The central air conditioner has a heating unit. The heating pump is a part of the air conditioners condensing unit and it part of the larger mechanism that sits outside all year long in all kinds of weather. It isn’t really a surprise that this unit will eventually need a little care and attention to keep it running as it should. It is not a bad idea to perform an annual maintenance even before such signs of trouble like dripping can start.
Reading the manual
Before starting if you have not worked or performed on this air conditioner before it is a very good idea to take a look at the manual before starting. Often there are tips and tricks for your make and model listed that will make working on it easier.
Step 1 - Shut off power
Blow leaves or debris away from the area. Shut off the power to the unit. This means you will need to find the electrical disconnect switch and turn off the 240 volts of power coming into the unit. The disconnect switch is usually in a weatherproofed metal box located outside somewhere in the area of the condensing unit.
You will also need to turn off the power at the main electrical service panel.
Wait a few minutes before you start to allow any stored charged to dissipate.
Step 2 - Check for all issues
As long as you are performing maintenance of the air condition you should go ahead and check for all issues as you go along. Remove the grill so that you can assess the inside of the air conditioner and clean the fan, motor, and interior of the unit.
You will need to remove the screws holding the side and top panels in place using a flat blade or screwdriver or socket driver. Remove the side grill away from the unit and place the screws in a container of some sort. They might get lost if simply pocketed so put them someplace safe for the time being. When you can locate the fan motor go ahead and give it a few drops of lightweight household oil into each port.
Step 3 - Vacuum
Vacuum the outside of the coil fins and the condensing unit. Use the small brush to get at any debris that might be clogging the heating unit.
Step 4 - Check for bends
Look for any coils that seem bent or for anything that seems out of place. Straighten out any bent fins if possible and then replace the grill cover.
Step 5 - Restore power
Switch your thermostat off and restore the power. Wait a few minutes then switch the thermostat back on.
