For some people, a malfunctioning air conditioner is no big deal. For Australians, however, it can be a nightmare on any given day.
If your AC unit hasn’t been working up to standard, it may be time to drop the DIY articles and call a professional technician. While the issue with your AC might look, sound, or smell inoffensive on the outside, its inside parts might require careful maintenance.
Also, if bills are an issue right now, trying to fix the problem yourself could be costly. Cause any damages to your system, and you may risk voiding your warranty. Yes, even if you “knew what you were doing.”
With all that said, look out for the following signs that your AC is overdue for a service.
It Is Blowing Warm Air
If your unit offers powerful cooling in extreme heat, blowing warm air is usually not a good sign. Of course, you don’t own an AC so it can blow warm air. Otherwise, you’d just get a good old fan.
This issue could be happening for a couple of reasons:
- The unit might be low on refrigerant, which your AC depends on to work properly. A refrigerant leak could be the culprit
- Your air filters might be clogged, which means the airflow will be reduced. This, in turn, will make proper cooling impossible.
While it is safe for you to remove and clean the air filter yourself, other potential root causes can be better handled by a technician.
It Is Releasing Bad Odours
A musty odour coming from your vents is a dead giveaway of mould and mildew buildup.
Yes, you could remove your air filters and clean them up. But if your ducts are clogged, calling up an AC professional might be a better idea. Otherwise, you will be encouraging unhealthy stale air to be trapped in the room.
This trapped air could be getting you, your employees, or your family sick more often, resulting in nothing but higher bills at the end of the month.
You’re Noticing Water Leaks
No, it isn’t normal for water to drip down your AC unit. There are two common causes for water leakage:
- The condensate drain line is clogged. This humid, confined space is the ideal growing environment for mould, mildew, and fungi. Without proper servicing, this obstruction will eventually result in dripping and puddling.
- Your unit could also be low on refrigerant. Low levels of refrigerant mean the pressure inside your AC is higher. This can freeze your AC coil, which will melt and drip over time.
There are several other potential causes for water leaks. It may need a new pan. The air filter may be dirty. The best way to find out? Ask a professional!
You’re Hearing Noises
You’re trying to sleep at night, and you hear your AC rattle and pop. These odd sounds aren’t as comfortable as the usual, nearly inaudible humming.
Be aware of other sounds, like unusual squealing, whistling or hissing. Whether they’re persistent or happen at infrequent intervals, these indicate that your AC needs to be checked.
Common causes for weird AC noises typically include:
- Loose parts
- A bad condenser coil
- A malfunctioning compressor
- Refrigerant leaks
A single issue could cause a bunch of different noises. If they’re bothersome, it is time to get the problem solved.
Higher Electricity Bill
If you haven’t kept your AC running for longer and your electricity bill is still high… something’s wrong.
During warmer months – or, in Australia’s case, heatwaves – your unit will have to work harder. Yet, that doesn’t mean you should see a spike on your bills when comparing it to last year’s. Unless, of course, your unit needs urgent service or replacement.
An AC technician will tell you whether the issue is repairable or if you need a brand-new unit. Either way, you will pay less than you would if your bills keep increasing.
If you’re currently dealing with any of the issues above, professional servicing is the best way forward.
