Goodman A/C Condenser
This home maintenance guide was specifically written to assist owners of the Goodman brand A/C condenser model # GSC130361FA in cleaning dust, dirt, debris, or pet hair from the metal coils to ensure maximum energy and cooling efficiency.

Owners of other similar HVAC condenser units from various manufacturers such as Gibson, Rheem, Trane, GE (General Electric), Mars, Carrier, York, Lennox, Frigidaire, Kenmore, Mitsubishi, Maytag, and Whirlpool may also find this guide to be helpful.

The only tools needed to complete this procedure include a flathead screwdriver, a wet/dry shop vacuum, coil cleaning spray, and a garden hose.

Some suitable alternatives to commercial HVAC coil cleaning spray include any foaming degreaser, a multi-purpose cleaner such as ZEP or Simple Green, and household dishwashing soap mixed with warm water in a sprayer bottle.

The first few steps are to turn off the A/C system at the thermostat, turn off the power supply to the HVAC system at the breaker box inside the house and turn off the breaker switch for the condenser outside the home.

Remove Flathead Screws
Then gather up a flathead screwdriver (your condenser may have Phillips head, Torx, or hex head screws instead), a wet/dry shop vacuum for removing debris from the bottom of the unit, the coil cleaning spray of your choice, and a garden hose with a spray nozzle attached.

10 Screws Removed
Lift Up Top Cover
There were 10 short flathead screws holding the top cover and fan motor in place on this Goodman condenser unit.

Once all the screws were removed, I gently lifted up the top of the case.

I used a scrap piece of wood to partially support the top cover and rested the fan housing on the coils.

Be sure to not stress the wires that connect the fan motor to the rest of the condenser.

It would have been best to have someone hold the fan motor while you clean the coils, but this procedure can be done by just one person.

Vacuum Out Debris
Next, use the wet/dry shop vacuum to remove all of the leaves, twigs, and debris that has settled on the bottom of the condenser unit.

Don't be tempted to use the wet/dry vacuum on the condenser coils because the powerful suction will cause the hose attachment to bend and damage the fragile aluminum fins.

Although you could swap the hose to the other connection on the wet/dry shop vac and gently blow out the coils first before getting them wet in the next steps.

Just don't hold the hose too close to the fins since they could be bent that way as well.


Do Not Stress Wires
Pet Hair & Dust
Condenser Coils
Thoroughly spray down the coils inside the condenser with a cleaner such as HVAC coil cleaning spray.

I just happened to have a bottle of Zep All Purpose Cleaner & Degreaser handy for the job.

I also saturated the outside of the condenser unit's case with the cleaning spray to help dislodge any debris stuck to the outer side of the coils or the ventilated metal case.

I let the Zep cleaner sit for a few minutes before flushing the coils inside the condenser with the garden hose nozzle.

If you have an adjustable spray head, set it for the "shower" or any other relatively gently setting that won't bend the aluminum fins.

It's best to spray from the top to the bottom of the coils and repeat the process several times all around the inside of the condenser to ensure that as much dust, dirt, debris, and hair is removed from the coils.

Thoroughly Spray Coils
Rinse From Top To Bottom
If your condenser's coils are severely clogged, you may want to consider taking the time to remove the entire metal case that surrounds the condenser to get better access to the outer side of the coils.

Cleaned Condenser Coils
The coils in this condenser weren't all that dirty, so I just flushed the outside of the case with the hose and sprayed water down into the small gap between the coils and the metal case.

Rinse Between Case & Coils
Once you're satisfied that the coils are spotlessly clean, you can gently lower the fan motor and top of the case back down onto the condenser unit.

Try to avoid putting stress on the power wires or pinching them between the top cover and the rest of the case.

Replace Screws
Check that all 10 of the screw holes in the top cover line up with the corresponding hole in the outer case.

Then insert the screws and tighten them with the screwdriver.

To finish the job, flip the outdoor breaker switch by the condenser to on, turn on the switches for the HVAC system inside the home's breaker box, and turn on the A/C system at the thermostat.

You should shortly afterwards hear the fan motor start spinning and the air handler should begin blowing out cool air.
