Do I need to maintain my air conditioner?

Yes, you do.

Air conditioning systems are designed to provide homes and businesses with a comfortable, healthy and safe air temperature. When a system is well-maintained, these advantages can be enjoyed without worrying about the quality of air that is being circulated around a room. Exactly why an air conditioner should be kept clean and maintained is not widely known by everyone. This week we will answer this question and more, specifically what maintenance you can do yourself, and what is best left to a professional air conditioning servicing company.

Potential Health Risks

Poor maintenance of air conditioning units leads to a buildup of dust and dirt around the intakes, outlets, air filter and condenser coils. Left unattended, this will cause allergens and microscopic organisms to be circulated through the air undetected. Allergies, asthma and sinusitis are known to be aggravated by these particulates.

More serious problems can occur if an air conditioning unit is contaminated with bacteria, fungi, moulds or viruses. In severe cases, legionella bacteria can grow inside an unmaintained unit and spread through the otherwise fresh air. Legionnaires disease is rare and treatable, but it has been fatal to those with weakened immune systems and the elderly. So it is a prime example of how important air conditioning maintenance is to the health of homeowners and businesses alike.

What You Can Do to Prevent Health Risks

It is easy to clean air intakes and outlets, as these are accessible without tools or specialist knowledge. Wiping away obvious dust buildup and finishing it off with an antibacterial wipe will prevent problems for those with allergies or asthma.

Professional Cleaning and Energy Savings

Air filters, air condensing coils and other internal components should be inspected by a professional once a year to maintain each and every air conditioning unit in a given property. Having the units professionally cleaned around these vital areas, and having a change of air filter, will stop the worst kinds of bacteria and fungi from settling and multiplying in your home or business.

The good news doesn’t stop there, with a regular maintenance check by a trusted and accredited technician, you will save money on energy bills. Excessive dust and dirt can cause your unit to be 10-15% less efficient than a regularly cleaned unit. An annual service is a low-cost investment that will see a return over the years as your air conditioner delivers the perfect temperature at peak efficiency.  

You can expect a qualified air conditioning engineer to do the following checks:

  • Check for the correct amount of refrigerant
  • Test for and seal any leakages
  • Legally and safely contain refrigerant that must be drained from the system
  • Optimise airflow through the evaporator coil
  • Verify that the heating system and cooling system cannot operate simultaneously
  • Inspect electric terminals and clean and tighten connections
  • Check belts for tightness and wear
  • Check and oil the motors
  • Check thermostat accuracy
