Clean Your Window Unit Hvac: Diy Sprucing up the inside of your own window Hvac system will help restore it to glory and eliminate any mildew and mold that might have gathered inside. Even if the unit is functioning without problems, it's a good idea to give it a clean once a year to make sure it's performing effectively. Check the filter once a month and clean it anytime it looks dirty. What You'll Need: Hand-help spray bottle Fin comb Buckey Rubber Gloves Coil Cleaner 2 Soft Cloths Vacuum Soft Bristle Brush Goggles 1 The Basic Clean: Detach the system from all power sources. Unplug all cords going into the unit. If the window unit is wired directly to your home, disconnect the unit from the fuses (or turn off the master circuit breaker). Foll
ow the manufacturerís directions for discharging the capacitor. A capacitor is a device that holds an extra charge to help kick-start the Air conditioning motor, so this step is critical to make sure that there isn't any electrical charge left in the unit before you start cleaning. 2 Clean the outside cover. Wipe down the outside of the window unit using a wet cloth. Make sure to get all the dust and grime off as possible so it doesnít drop inside the unit when you open the cover. 3 Take off the front cover. A few covers could be pulled off easily with your hands. Other covers may have plastic hooks or screws that have to be removed. Place any screws or clamps in a safe area while you work. Note: A few devices also have a metal grill that needs to be removed. Be careful as you manage the grill, the metal edges can be sharp! 4 If your system has a reusable filter, it needs to be cleaned. Take off the filter from the Air conditioner. Put the filter in a container (a sink or bathtub will work) filled about midway with warm, soapy water. Swish the filter around to wash off any dirt or accumulation. When the filter is really dirty, you may need to use a soft brush to get rid of everything. Set the filter aside and allow it to dry fully before returning it to the Ac unit. A moist filter will attract extra dirt and mold! 5 If your unit has a disposable filter, change it on a regular basis. The U.S. department of energy recommend that filters be switched out monthly during the cooling season. 6 Clean the inside of the system. Use a vacuum extension to clean the base and sides of the system, the back of the front cover, and the metal grill (in case you have one). If there is lot of dirt, you can also use a damp cloth for this step. 7 Reassemble the unit. Let the unit to fully dry before reassembling. Connect the window unitís power source and turn it on. Clean up any dust that may blast out when the unit is powered on again. 8 Store your system in a dry place. When itís time to put your Ac unit away, cover it with a sheet of plastic and place it in a dry area to avoid the development of mildew and mold. 9 The ìAbove and Beyondî Clean. If you want to go the extra mile with your hvac, there are a handful of additional steps you can take before reassembling your unit. Be gentle while you conduct these steps. The coils and fan blades are delicate and easy to bend accidentally. The engine housing can also be sensitive and should be avoided while washing. 10 Clean the coils. Put on your rubber gloves and protective goggles. Add your coil cleaning solution to the water bottle. Lightly spray the coils (and only the coils) with the solution and enable it to sit for about 10-15 minutes. Next, carefully pour warm water over the coils. Make sure all coil cleaner is removed. Note: Avoid getting water on any electrical parts near the coils. Consider putting a dry rag over any electrical parts to prevent water damage. 11 Clean the fan blades. Use a soft, clean cloth to wipe off any dust on the fan blades. Wipe lightly to prevent bending the blades. A bent blade can make your Air conditioning unit even louder! 12 Use a fin comb to repair any nicks in the fins of your coils.
