Check your air conditioning system before it fails. Here we'll explain the risks of failing to do so, and how to extend its lifespan.

Couple seeks information on what maintenance an air conditioner needs.

Air conditioning is now so commonplace in homes, offices, and commercial properties that we often overlook the need for regular maintenance, just like with any other appliance. Until, of course, one day it stops cooling just when you need it most. Or it starts to give off a strange smell. Or it becomes noisier than usual. And then we remember that all-important detail: to keep it working properly, it needs regular care.

In this article, I’ll give you some clear, practical advice on everything you need to know about maintaining air conditioning systems. No unnecessary jargon, just the important stuff: why it's crucial, what risks you run if you neglect it, how often you should check it, what types of maintenance there are, and how to identify when your system is crying out for help.

And yes, I’ll also tell you why Daikin, a leading brand in the sector, is a reliable choice for those seeking efficiency and peace of mind.

Why is maintaining air conditioning important?

Let's start with the obvious: Maintaining your air conditioning isn’t a luxury or an unnecessary expense. It’s an investment in health, savings, and longevity.

Here are the main reasons why you should take it seriously:

1. It improves performance

With use and time, air conditioning collects dust, dirt, and moisture in its filters, ducts, and coils. This means it has to work harder to achieve the same result. With proper maintenance, the system runs more efficiently, heats or cools better, and uses less energy.

2. It extends the unit's lifespan

With good maintenance, an appliance can last for many more years without major breakdowns. And considering the high cost of a new air conditioning unit, anything that extends the life of your current one is more than welcome.

3. It improves air quality

Did you know that a dirty filter can become a breeding ground for bacteria, unpleasant odours, mould, and dust? If left uncleaned, that’s what you and your family will be breathing. Proper maintenance improves indoor air quality, which is especially important if children, older people, or allergy sufferers live in the home.

4. It prevents expensive, troublesome breakdowns

Most serious breakdowns could be avoided with regular maintenance. A simple annual checkup can catch problems early, potentially saving you from significant expenses later on.

So what happens if I don't perform regular maintenance?

Good question. Because when it comes to maintenance, many people think, “Well, if I don't touch it, it'll be fine.” Wrong. What you can’t see still matters. And doing nothing also has consequences.

Here are some of the most common risks of neglecting air conditioning maintenance:

  • Soaring electricity consumption: the system loses efficiency and uses more energy to heat or cool the same space. You’ll end up seeing this on your bill. 

  • Frequent breakdowns: without proper cleaning or checkups, parts wear out and eventually fail. And repairing compressors or electronic components can be costly.

  • Unpleasant odours: mould and accumulated moisture can cause unpleasant odours when switching the appliance on.

  • Poorer air quality: a dirty filter spreads allergens, dust, and microbes throughout the room.

  • Too much noise: fans become misaligned, parts rub together… and quiet operation is lost. 

  • Loss of warranty: many brands make the warranty for the equipment conditional on servicing it at least once a year.

Types of maintenance: what does your system actually need?

Not all systems or situations need the same approach. However, we can generally distinguish between two types of maintenance:

1. Basic maintenance (which you can do yourself)

This involves simple tasks you can carry out without a service technician or specialist tools.

  • Visually inspect the system: check there are no leaks, that the appliance isn’t making strange noises, and there are no loose parts.

  • Keep an eye on the surrounding area: make sure that the outdoor unit isn’t blocked by leaves, dust or debris, and that there’s plenty of space for ventilation.

2. Professional servicing (service technicians only)

Air conditioning systems should be serviced at least once a year, ideally before the summer or winter, depending on whether you use heating or cooling most. This includes:

  • Complete system check: general operation, condition of the electrical connections, refrigerant gas pressures, etc.

  • Deep cleaning: cleaning the coils, fans, drains, and interior trays, which cannot be done without first dismantling the unit.

  • Refrigerant gas check: if there’s been a leak or drop in pressure, the service technician can recharge it.

  • Measuring energy performance: to ensure your system remains efficient.

How often is maintenance needed?

The short answer: once a year.

The long answer: it depends on how much you use it, the type of system, and whether it’s installed in a home, office, or commercial property.

Here’s a quick guide:

  • Occasional home use (summer and winter): once a year.

  • Intensive home use (all year round): twice a year.

  • Commercial properties / offices: at least twice a year.

  • Environments with lots of dust or grease (kitchens, workshops, etc.): more frequent maintenance, possibly even every three months.

The best time to do it is before peak season. This will ensure you avoid any unpleasant surprises when you need it most.

How to know if your air conditioner needs maintenance

Your appliances will tell you. Sometimes quite literally. If your air conditioner is showing any of these signs, it probably needs a checkup:

  • It doesn’t cool or heat properly: this could be down to dirty filters, a lack of gas, or a problem with the sensors.

  • It’s making more noise than usual: if it was once quiet but now sounds like a car engine, then something isn’t quite right. 

  • It gives off an unpleasant smell when you turn it on: a clear sign of mould or accumulated dirt.

  • It powers off or leaks water: this may indicate electrical faults or drainage issues.

  • Your electricity bill has risen unexpectedly: watch out for this, it often means the system is working harder than it should due to dirt or poor regulation.

Don’t wait for things to get worse. A timely checkup can save you hassle (and money).
