You can never deny how important an air conditioning system is especially on a hot Toronto summer day. A perfectly working air conditioner works day in and day out to make sure we feel cool and comfortable throughout the warm season. Unfortunately, there are times when the air conditioner starts acting up and emits warm air instead of the cool air we have become acclimated to. An A/C blowing out warm air may be due to a bad compressor or your unit has run low on refrigerant. A warm-air-emitting air conditioner may not only be the sign of a failing cooling unit. It can be as worse as having an A/C that spews out a horrifyingly stinking breeze.
An unpleasant smell coming from an air conditioner is a sign that something is not right with your unit – even if it still gives you the cool air that you expect. If you are faced with a dilemma like this, it may be because of the following reasons which will ultimately demand for a professional repair.
Your A/C Isn’t the Right Size
The size of your air conditioning unit matters – a lot. Remember that your A/C not only cools down your home’s temperature, but it also plays a very important role in dehumidifying. As it takes the heat from the air, it also gets rid of moisture. And while a bigger air conditioning unit for a relatively small space may give you better cooling effects, it won’t help much with the dehumidification process. When an A/C is too big for a specific room, it doesn’t do a full cycle which means it is also unable to effectively remove the humidity from the air. Air conditioning
With an A/C that is too large for the zone it’s cooling, this becomes a breeding ground for particles that can have a direct effect on your health. During the hot summer days when the humidity level is high, mold and mildew can stick to the dampness of the air conditioner and eventually grow on the unit’s components. These will eventually spread and be emitted together with the air that you breathe. Not only will you be experiencing an unhealthy dose of cold air but you will also be smelling something unpleasant. You can correct this problem by either running a dehumidifier or changing your air conditioner to a size and make that is suitable for your room.
Your Condensation Drain is Clogged
The dehumidifying functionality of an air conditioner certainly has positive effects on the kind of air we require; however, this can also contribute to the smelly breeze you get from your unit. That nasty smell may come from a clogged condensation drain that becomes a breeding ground for mold and mildew. This happens when the frost layer on the evaporator coil starts to condensate and eventually drains into a pan located outside the house. This pan can get easily clogged and so the condensation process isn’t completed so the mold that has started to grow in the pan gets distributed in the rooms of your home in the form of a dirty sock stench.
You can simply drain the pan with a sharp object. In case it doesn’t fix the issue you have with your air conditioning unit, you may need to call in the experts so they can assess what needs to be done.
You Have Dirty Internal Coils
An air conditioner consists of several coils that are used to heat and cool the air before it gets redistributed to your home. One of the possible reasons why your unit discharges that stench is because of dirt and bacteria-infested internal coils. Because the air passes through these coils, it picks up the foul odor and that is what you smell. The easiest way to clean internal coils is to turn your A/C off and spray the coils with compressed air. It is also advisable to do the same before using it for the summer to clean the dirt that may have built up on the unit.
Your Filters are Clogged
Filters play the role of cleaning the air in the air conditioner before it gets distributed to your home. If filters are not regularly changed and cleaned, these can get clogged and be embedded with dirt and bacteria-infested particles that produce the foul smell that the air can pick up. It is recommended that you change your filters at least once a month to avoid the stinky smell and prevent your A/C from working harder than it should.
You Have Dead Animals in Your A/C Unit
What could possibly be the worst reason why your A/C is sending out that horrid smell? Dead animals. It could be a rat, a possum, or a bird. Any of these can die in the outside unit or even in the vents. It is important that you call in some professionals to remove dead animals especially in the vents to make sure that the unit gets cleared of these expired creatures and avoid possible health risks. Once your air conditioning system is free from these animals, you can enjoy a comfortable temperature without the annoying smell.
Note that air conditioners don’t normally smell. If yours does, you might just have a valid reason to call for a professional air conditioning repair.
