This guide will walk you through everything you need to know about AC servicing, from why an annual check up is the golden rule to when your system might need more frequent attention.

One of the most common questions we hear is: 
"How Often Do I Really Need To Service My Air Conditioning Unit?"

It's a great question, because getting the maintenance right can save you heaps of money and hassle.

The short answer is at least once a year.

We always recommend an annual professional routine maintenance to keep your system running in top condition. However, there are a few things that might mean your system needs attention more often. 

While this guide focuses on split system air conditioning, regular maintenance is key for ducted systems like evaporative cooling too.

📆 When to Schedule Your Aircon Service 📆

Once a Year Servicing

This is the golden rule for most homeowners. An annual service is enough to catch small problems before they become major issues. 

It keeps your air con system efficient, lowers your electricity bills, and ensures your warranty stays valid. We recommend getting it done just before the weather heats up, so your air conditioner is ready for summer.

Twice a Year Servicing

If you use your air conditioner heavily all year round, a biannual service is a better option. This is especially true for businesses, or if you run your reverse cycle air conditioning for both cooling in summer and heating in winter. 

Getting a check up every six months ensures the system can handle the constant useage without breaking down.

After a Repair Service

If your unit has just had major repairs, we recommend a follow up check up within a few months. This is a simple way to make sure the fix is holding up and that your system is back to its best.

If You Notice a Problem…

If your air conditioner unit is showing signs of trouble, like weak airflow, strange noises, or a sudden rise in your energy bill, it's trying to tell you something! 

Don't wait for your next scheduled service; give it the professional attention it needs now from air conditioning specialists.

Why Is Regular Servicing So Important?

Think of your ventilation and air conditioning system like your car. You wouldn’t drive it around for years without an oil change and general check up, right? This is the same for your air conditioner: regular maintenance services keeps your system in top condition and pays for itself in the long run.

The benefits of frequent servicing are huge!

✅ Saves You Money

✅ Extends Lifespan

✅ Avoids Breakdowns

✅ Keeps Your Warranty Valid

When it comes to your air conditioner, a little preventative care goes a long way. If you’re unsure whether your air con is due for a check up, it’s always better to be safe than sorry!

Quick Tip: A Simple Task You Can Do Yourself

While a professional service covers all the important parts of your air conditioning system, there is one simple task you can do yourself to help your AC run better: change your air filters.

A clogged air conditioner filter makes your indoor unit work much harder, leading to higher energy bills and even system breakdowns.

Simply find your indoor unit or return vent, remove the old filter, and slide a new one in. It's a small task that makes a big difference in both your aircon's efficiency and your indoor air quality.

⏰ Don't Wait Until It's Too Late for Your Aircon Service!! ⏰

A little preventative care now can save you from major repairs and a major breakdown later.
