Can dirty air conditioners make you sick?

Posted by Andrew McNulty, Owner, Air Central on 14 February 2018
Lets face it, most of us can't live without our air conditioners. But could your air conditioner really be making you sick? We have put this article together to help people understand the health advantages of having a clean air conditioning unit.

Most home air conditioners lay relatively dormant during the autumn and spring seasons and then get a much bigger workout in summer and winter. But what happens when we switch the air conditioner on to enjoy the cool or warm air - have you ever stopped to think about the quality of the air that your unit is generating? This article will help you understand how a dirty air conditioner unit could make you unwell.

How can an air conditioner carry allergens & bacteria you might ask?

To cool or heat a home your air conditioner needs to blow air over the evaporator coils. As the air blows over these coils, the moisture in the air condenses and collects on the coils. This moisture then becomes a magnet for dirt, dust and bacteria and becomes the perfect environment for mould, mildew and bacteria to grow. Home owners will often tell us that they maintain their air conditioning unit themselves by dusting the outside and cleaning filters regularly which is a great start, but unfortunately, it's inside the unit where you can't see where the problem generally lies.

Another common problem that can occur in air conditioning units, is a blocked drain line. An air conditioner drain is designed to carry excess moisture from the evaporator coils, but the drain often becomes blocked over time causing water backup - another ideal breeding ground for mould and mildew.  A professional air conditioning cleaning company can conduct a complete sanitise and clean of your air conditioning unit both inside and out to help resolve these types of issues.

Can my air conditioner really aggravate my allergies & asthma?

If your air conditioning unit is regularly cleaned and maintained by a trained professional, there should be no problem with the air quality coming from within your air conditioner.

However, if you have recently purchased a home and you have no idea when the air conditioning unit was last serviced, or if the previous occupants were cigarette smokers, it's probably a good idea to book a maintenance clean to be sure that the air recirculating throughout your home is fresh. This can be particularly important if you have an infant, an elderly person, allergy or asthma suffer living in the home.

The cool and warm air that your air conditioning unit generates alone won't make you unwell but any germs, dust and bacteria living within your air conditioner could certainly aggravate allergy or respiratory problems when the unit is running.
At Air Central, we recommend having your air conditioning unit professionally cleaned at least once a year to help maintain good air quality. This maintenance cycle may vary though depending on how often you use your air conditioning system for year round users a 6 monthly clean and sanitise may be required.
