The Importance of Regular Maintenance

Regularly servicing and maintaining your air conditioning comes with a long list of benefits. Not only can it preserve the system warranty, but it also ensures the system is functioning properly and efficiently, working to cool your home or office effectively while keeping energy bills down.

Regular maintenance and cleaning can also prevent potentially harmful toxins from circulating in the air in your home, keeping the air you’re breathing clean and free from impurities.

System Performance

Neglecting to regularly maintain your air conditioning system can have a dramatic impact on performance, resulting in costly energy bills.

It’s not uncommon for poorly maintained air conditioners to:

  • Struggle to effectively cool (or heat) your home.
  • Place additional strain on the system to produce the desired temperature, increasing power consumption.
  • Malfunction, resulting in damage to parts and components.
  • Experience blocked drains, leaks or spillage.

Regular servicing and maintenance will ensure any system issues are picked up early, with most problems being a relatively easy fix. However, when issues are left ignored, they often lead to bigger, more complex problems which are costly to repair.

The Health Risks

Regularly maintaining your air conditioner can also protect you and your family from experiencing a range of health problems.

Airborne Toxins

While the filters in air conditioners do a great job removing toxins from the air, they do need to be cleaned regularly and replaced if damaged to be able to work effectively.

When left unchecked, there’s nothing to prevent the system from circulating impurities including dust, dust mites and other allergens which are known triggers for conditions including asthma, nasal irritation and eczema. Air conditioners can also accumulate bacteria, germs and mould, which can cause similar health issues when breathed in.

Refrigerant Leaks

Air conditioners are also prone to refrigerant leaks. Refrigerant contains an odourless and tasteless gas known as Freon (or fluorinated hydrocarbons), which when ingested, can cause serious health issues including cutting off vital oxygen to your lungs and cells.

Refrigerant leaks can also cause significant damage to your air conditioning unit, so it’s important to get onto them quickly.

House Fires

Like any electrical appliance, the components in air conditioners can become worn-out and damaged with ongoing use. While unlikely, if a part was to malfunction, it could present a fire risk. The accumulation of dust in your air conditioning system can also pose a fire risk.

Air Conditioning Maintenance: What’s Involved

To ensure your air conditioning maintenance is up to scratch, you may be able to perform some basic maintenance tasks yourself. More advanced maintenance tasks are generally best left to the professionals.

Basic Maintenance - Cleaning the Filters

In between professional servicing, it’s important to regularly check and clean the filters of any dust or debris.

While you should follow the instructions provided in the user manual for the specific unit, it’s generally quite easy to remove the filters and use a brush to remove any build-up before rinsing them in clean water. Ensure the filter is completely dry before putting it back in the air conditioner.

Advanced Maintenance

In addition to regularly cleaning and changing the filters in your air conditioner, other maintenance tasks that need to be conducted regularly include:

  • Checking refrigerant pressures, service valves and piping.
  • Inspecting air ducts for damage or blockages and conducting an airflow test.
  • Inspecting condensers, pump, drain pan and the evaporator coil to ensure they’re clean and functioning correctly, also checking the high and low pressure settings.
  • Vacuuming drain lines.
  • Testing contactors, including looking for indentations or burns.
  • Checking fans for any cracks or damage.
  • Conducting an air balancing test and checking the air quality.
  • Undertaking static pressure testing.
  • Checking the thermostat is functioning correctly and conducting a thermal efficiency analysis.
  • Checking refrigerant operating levels.
  • Inspecting all electrical wiring for damage and measuring compressor voltage draw/amperage.

If you’re confident you know what you’re doing you may be able to attempt some of the more advanced maintenance tasks yourself, however, they’re usually included in a professional service so you may want to save yourself the trouble.

While the tasks included in a professional service will vary depending on the company you use, at Easy Cool Air, our air conditioner servicing always includes all the tasks just listed to ensure your air conditioner is operating in optimal condition.

Preventing Mould and Bacteria Build-Up

When servicing and maintaining your air conditioner, it’s also good to conduct hydro sanitise cleaning to ensure the system is free from bacteria, fungi, mould spores and viruses, giving you confidence that the air circulating in your home is clean and safe.

How Often Air Conditioners Need Servicing

How frequently your air conditioner needs to be serviced largely depends on your usage levels. Air conditioners that are in operation 24/7 will require frequent servicing, while air conditioners which are only used occasionally can afford to go longer between each service.

We generally recommend our customers have their air conditioning serviced:

  • at least once every 12 months for residential customers, or
  • every 3 to 6 months for customers with higher usage levels, such as commercial clients.

Signs Your Air Conditioner Needs Maintenance

Some common signs that your air conditioner needs maintenance include:

  • it’s not cooling (or heating) effectively or efficiently
  • the temperature fluctuates
  • unusual smells or sounds
  • unusual smells or sounds
  • increasing energy bills, or

Nathan did a fantastic job in installing our aircon unit ready for the arrival of our baby! He also did a very thorough job in servicing our 2 other aircons that had been neglected for quite some time. He answered my call promptly upon first contact, sent me a quote and completed the work all in a matter of days and left the place tidy. Definitely recommend and will definitely use in the future. Thanks Nathan.
