How Do I Clean My Condensing Unit?

This isn't a hard task and on a bad day may take you two hours. When I did mine, it took an hour, with most of the time spent letting the cleaning solution sit on the fins and loosen up the dirt. Just so you know, the coil did not appear too bad for the naked eye, but I'd really large refrigerant pressures when I had my gauges connected to the device.

Beware of electricity! To proceed with move in specials near me, you need to use the disconnect switch which is located close to your unit, normally mounted on the wall at close proximity. Code requires one to be there, so if you don't see one, you might have to place this on your to-do-list. Anyway, make sure that the device is electrically isolated even if you want to extract the multimeter and check. Also, visit the thermostat and move the lever to the"off" position.

Tools You Will Need

No special tools are needed for this procedure. All you want is:

* Work Gloves, unless your hands are already calloused.
* Vacuum Cleaner with a soft bristle brush. Best to use a Wet-Vac, not the wife's vacuum.
* Screwdriver/Wrench to remove the very top of the condensing unit and enthusiast.
* Cleaning Option safe for the (normally aluminum) fins and coil (Household cleaners work)
* Breathing Mask, if dust bothers you.
* A couple of pliers to rub down the unit.


* Eliminate bushes and plants within 2 feet of this unit. Air flow to the device should be unobstructed.

* Grab the digital camera and take pictures of the unit, top and all four sides. This is a fail safe way of documenting what the device seemed like before you started this procedure and can be utilized when you are completed.

* Use a hairbrush or whisk broom and GENTLY brush the loose dirt from the fins. Start at the top most section of the fins so that the dirt falls down to additional fins which have not been cleaned yet. The vacuum with the soft bristle brush will work a little better because it will collect the dirt rather than brushing it on adjoining fins. Brush gradually in precisely the exact same direction of the fins. Do not bend or deform the fins by being overly competitive.

* Eliminate the top of the unit (usually screws) to gain access to the inside. This will probably also remove the fan and fan motor, so be careful not to yank on the wires. You'll have to reposition the very best since you proceed with cleanup to get within the unit better. Note: The shirt retains the coil in the appropriate position on some units that might cause them to lean somewhat once the top is removed. Just be careful not to push or lean on the coil when the top is removed and all will be helpful.

* While the top is off, do a little inspecting for discolored cables, deteriorated tubing insulation and items of that type. The insulation can be repaired easily, but anything else should be left to the professional.

* Inspect the coils again, this time from the interior of the unit. Use the hairbrush or whisk broom as described above in the event that you discover considerable quantities of dirt around the coil.
