Jack Frost is nipping at our nose and Santa Clause has just left. The eastern seaboard has just received their third blizzard for a total of over 125 cm (56 inches) of snow in one week. So, who in their right mind would be thinking about window air conditioners at this time of year?
Call me crazy, but I am.
It is a good time of year to start this project. Firstly, it keeps ones mind sharp for the coming spring. Plus, it allows you to try out those new tools you got for Christmas. Mainly though, it is a good winter project because by the time spring arrives you will be too busy to think about this job.
Very little is required to clean a window air conditioner, except lots of patience. If patience is something you lack then it is a job you should turn over to the local appliance serviceman.
Tools ———————-
·Tin can or container (old muffin tin works well also)
·Vacuum cleaner
·Long handled brush (an old toilet brush works well)
·Oil can
·Rags
·De-greaser or spray detergent
·Selection of screwdrivers (Philips, Flat bladed, 1/4″ socket head)
·Fin tool (optional)
·New filter (if disposable type)
Lets get started ———–
1. Start by removing the filter from the front grille. If it is a disposable type simply replace it with a new one. Other types are made in a plastic frame and can be cleaned and reused. To clean a reusable type lay it flat in the sink and sprinkle surface with laundry detergent. Then cover with about one inch of hot water. Just enough so the filter is submerged. Soak for 15 minutes. Remove from water and rinse with warm water. Hang up to dry while proceeding to next step.
2. Next, remove the front grille from the main body of the air conditioner. They usually pivot on 2 spring clips at the bottom. It is usually removed by pulling the grille gently forward while pushing it down at the same time. If there is resistance then look for hidden screws. Look near the top edge of the grille or behind the control knob door. Once removed place the grille aside until later.
3. Carefully remove metal cover of air conditioner to expose inner workings. Once all the screws are removed lift the cover straight up. Do not let it hit the other parts as it can have sharp edges. This is where the old can comes in handy (ice cube container or muffin tin works well also). Use it to keep track of all the screws you will be removing. An air conditioner will often use a number of different types and sizes of screws. Segregate them from each other or confusion will result when we start reassembly. 1/4″ to mm
