One of the most important things you can do for refrigeration and air conditioning systems is regularly maintain them. Proper maintenance should be done at least twice a year, preferably in spring and autumn. This is because air conditioning systems are exposed to high levels of dust and dirt, which can cause them to become clogged with impurities. Here are some tips for maintaining your air conditioning system:

Maintain or Replace Filters Regularly

An essential part of air conditioning maintenance is to change your filter regularly. A clean filter will allow your system to run more efficiently, helping you save money on energy costs. Most filters should be replaced every three months or as often as directed by the manufacturer. If your filter is clogged, it might need to be replaced sooner.

Check Refrigerant Levels

Checking refrigerant levels is also an important part of air conditioning maintenance. Low refrigerant levels can cause your system to run inefficiently and even lead to costly repairs down the road. Have a professional inspect your system regularly to ensure it has the right amount of refrigerant and that any leaks are repaired quickly.

Make Sure the A/C Vents are Unobstructed

Ensure the air conditioning vents in your home are not blocked by furniture, rugs or other objects. This can significantly reduce the efficiency of your system and lead to higher energy bills. Other obstructions like leaves and dirt should also be cleared away from the vents.

Inspect Belts & Motors for Wear or Damage

Inspect the belts and motors in your air conditioning system regularly to ensure they are not worn or damaged. If they are, it’s best to have them replaced by a professional. Your system’s efficiency will be improved, and you’ll avoid potentially costly repairs.

Measure Temperature Differences between Supply and Return Air Vents

To ensure your system works efficiently, measure the temperature difference between the supply and return air vents. If there’s a significant temperature difference, it could indicate that your system is not operating correctly and needs to be serviced.

Verify Proper Operation of Safety Controls

Safety controls ensure your air conditioning system is not running too long or too hot. Have a professional inspect the safety controls at least once a year to ensure they function properly. Signs of wear or damage should be promptly addressed.

Clean the Outside of the Air-conditioning Unit

Lastly, it’s a good idea to keep the outside of your air conditioner clean and free from debris. This will ensure that the unit runs properly and helps prevent any potential problems.



By following these tips for air conditioning maintenance, you can help maximise the efficiency of your system and reduce energy costs. Regular maintenance is key to keeping your air conditioning system running right and helping you avoid costly repairs down the road. Of course, if you ever have any questions about maintaining your system, don’t hesitate to contact a professional. The team at Gladstone Refrigeration & Air Conditioning is here to help!
