Keeping your air conditioner clean is the key to ensuring it works at its best all year round. Dirt, dust, and cobwebs build up with use – or even during the months when you’re not using your unit. This puts a strain on your system and can cause it to wear out prematurely or under perform.

When it’s dirty your air conditioning unit also has to work extra hard to deliver cold air, which will increase your energy use. You’ll save up to a third on your air conditioner running costs just by having it cleaned by Peninsula Air Conditioning.

Of more concern, mould and bacteria can contaminate your system, which can then affect the health of your family. A dirty unit also spreads bad odours throughout your home or business. Regular cleaning will prevent this and protects vulnerable family members or staff, like those with respiratory problems, asthma, or hay fever.

  • It rids your system of contaminants

As a general rule, you should clean your air filter when the filter light flashes, but this will vary depending on the air quality in your home and other environmental factors. In more dusty or polluted environments you should clean your filters more regularly. As a rule of thumb, you should clean your filters once every season, and once a month for commercial applications.

The moist environment created inside your air conditioner creates conditions that make it conducive for mould and bacteria to grow and flourish. This can happen in as little as three months. They tend to collect in areas that are hard to reach, such as the indoor coil, fan and drain pan and. Peninsula Air Conditioning use specialised HVAC cleaning products that will also reduce the rate of recontamination.
