5 Signs Your Air Conditioner Needs Servicing

 In Tips

Does your home or office feel a little warmer than usual despite your air conditioning system working overtime at max capacity? It’s probably time for a service.

We all know how hot and unforgiving the Australian climate can be. Perth’s climate is most similar to the Mediterranean, this means we also experience high humidity levels.

To combat those extremely hot and muggy days, we crank up our AC systems to stay cool and comfortable at home and the office.

After all, no one wants to be working in a pool of their own sweat.

Air conditioners make our lives so much more comfortable when temperatures climb or drop, but what happens when we rely on them too much? 

You may have already noticed the air isn’t as cool anymore, or maybe a strange smell is being emitted. 

You see, like your car or any appliance for that matter, they don’t last forever. Although, you can prolong the lifespan by keeping them well-maintained. 

A car that is regularly serviced and maintained will last much longer than one that isn’t. The same concept applies with your air conditioning system, which can increase its lifespan for up to 10 more years.

If you suspect your air conditioner needs a service, here are the top five signs to look out for.


1. Your aircon unit is blowing out hot air instead of cold, despite temperature settings

One of the most obvious signs your air conditioner needs a service is if it’s blowing out hot air or if the air coming out of the vents is not as cold as it used to be. Despite colder temperature settings, if it’s not blowing out cold air even at maximum settings, this could indicate an issue with the compressor or low refrigerant levels.

2. Giving off unusual smells or making strange noises

A well maintained and functioning air conditioning system should be near-silent and completely odourless.If your air conditioner is giving off a damp smell or strange odour, and it’s not just the dog casually letting one off, it may be time for a service. Here’s what to look out for:

Noise: Minor noises could indicate loose parts, a buildup of dust or dirt, or the fan is making strange noises. However, if you start to hear loud metal or plastic squealing, grinding or grating noises, this could indicate a far more serious issue that requires immediate professional assistance. If you do hear these sounds, turn the system off and get in contact with All Air Services.

Smell: Technically, you aren’t supposed to smell anything coming from your AC unit. So when you do catch a whiff of a foul odour, or a burning smell, this could mean the insulation has become damaged or the pads have become mouldy. Contaminated air caused from mould or mildew can be circulated throughout the house and be highly toxic, causing health issues for your family, especially asthma sufferers.

3. Unexplainable increase in electricity bills

If you’ve noticed a huge surge in energy costs, your AC might be the one to blame. First things first, it’s best to conduct an energy audit to factor in other appliances, and of course, if all roads lead to your AC unit being the energy-draining culprit you’ll need to consider getting it serviced. 

It may just be a matter of cleaning the air vents and replacing the filters, or checking for knots in the condensing coil. However, if this does not resolve the issue and your system seems a little sluggish, rather than wait for another massive energy bill, contact a professional and have it serviced, or replaced.

4. Notice a leak coming from the AC unit

Depending on the type of AC system you have, sometimes a small amount of condensation or water dripping on the outside of your unit is normal. However, if you start to notice small puddles of water or moisture around your system, particularly HVAC units, it’s important to contact a specialist for an inspection. 

A leak could be due to a blockage in the drain tube, or a refrigerant leak, which is potentially dangerous to people and pets. Ignoring a leak can lead to the growth of mould and mildew and can be highly toxic. It’s important to detect these types of air conditioning issues early before they become more serious (and expensive) repairs/replacements.

5. Needs constant repairs

To ensure your AC unit is running optimally all year round, it’s normal to have it regularly serviced and maintained for blockages, cleanliness and the odd repair by a professional. 

However, after years of neglect, if you find that you are repairing your air conditioner multiple times a year, and it’s already out of warranty — it’s probably more economical and efficient to replace it. 

Regular maintenance of commercial air conditioning systems not only increases its efficiency, it can also prolong the unit’s lifespan by up to 10 years. 

If you detect any of these 5 telltale signs that your ac system is malfunctioning, it’s best to contact the professionals at All Air Services. 

When your commercial air conditioner breaks down, not only does your business suffer, your customers do too. We understand the need for absolute comfort all-year-round, whether it be at home or at the office, and will work vigilantly to have your system up and running in no time at all.

How often should AC be serviced?

We recommend that commercial systems are maintained on a quarterly basis or every 6 months as a minimum for residential aircon units servicing
