Reasons Why Your Air Conditioner Isn't Cooling Down Your Room
Have you checked your unit's filters recently?
With heat indexes in some parts of the Philippines reaching the 50s during the dry season, having air conditioning is a blessing; however, it can be a bit frustrating if your unit is not cooling, especially if you’re working from home. Don’t panic: there are ways to find out what the problem is, and you may even be able to troubleshoot them on your own without having to call an expert. Here are issues you should check for:
The filter is dusty.
This is the most common reason as to why your air conditioner may not be blowing out cool air. Checking your filter is easy enough with a basic window unit, as this is often situated behind the front grill and is easily removable. Dust blocks proper airflow, so you’ll want to give it a good brush or vacuum it. If the filter is really dirty, you can wash them in warm water with soap—just make sure that it’s totally dry before putting in back in.
A split-type unit is just as easy to clean. Check this video out on how to do it:
There’s frost build up.
If you don’t dust your filters regularly and you’re running it non-stop, chances are parts of it may be frozen. Check for ice on your vents, or if your unit’s body is cold even if the air its blowing out is not.
A quick fix would be to allow it to defrost by simply turning it off for a few hours. Don’t use the “cool” setting until the ice has melted as this can damage your compressor.
It’s simply too hot.
Sometimes, your air conditioner won’t be able to compensate simply because its surrounding temperature is too high. To lessen chances of having your unit stall on you, make sure that the part of your unit that’s exposed outdoors have enough shade and are not in direct sunlight. If you think your AC is over-exerted, turn it off for the time being and use other means of cooling down like your electric fan—or simply transfer to the lower floors of your home.
You’ll need to call in a professional if:
1. You suspect your coils are dirty;
2. There’s not enough coolant in your unit; and
3. Your unit is leaking oil.
Unless you’re really sure about what you’re doing, do not attempt to disassemble your unit on you own. There are a lot of parts in your unit that you’ll want to keep dry and you’ll want to avoid touching, so you may want to wait until a professional is available to do the work for you.
