Is your air conditioner acting up and causing you a world of trouble? There are a number of common air conditioning problems that anyone can fix on their own, with expert help only being needed if the problem persists. By doing some basic maintenance and checks, you can not only troubleshoot common issues, but also prevent more serious problems from developing in the future. Here are some of our top tips for sorting out your air conditioning issues:
Check the filter
One of the most common culprits behind a malfunctioning air conditioner is a dirty filter. A clogged filter will hinder airflow, resulting in weak air conditioning performance. We recommend changing your filters once a month, especially if you use it frequently or you have pets. Dirty filters can also be to blame for any exacerbation in your allergies, as dirty air full of debris, dust and cat hair is being cycled through your home.
Check your refrigerant
It’s also possible that your coolant is leaking inside the air conditioner, causing the temperature to fluctuate. Repairing this issue will vary greatly depending on where exactly the leak is, so it’s best to call in some professional help for this one.
Shield from sun exposure
If your window AC is in a position that gets direct sunlight, it’ll have to work harder in order to operate effectively. If you can, try moving it to a shadier spot to see if performance improves. Otherwise, keep your curtains drawn to prevent the sun from affecting the performance of your air conditioner.
Change up your thermostat
Sometimes air conditioner problems can be as simple as the thermostat being on the wrong setting. Double check to see that it’s on and set to ‘cool’. The thermostat’s sensor might also have been knocked out of place, which can cause it to stop blowing out cool air. If you suspect this is the case, contact an air conditioning professional to sort out the sensor.
Ensure your AC is not vibrating
It’s normal for air conditioners to make some whirring noises, but if you hear a vibration, this could be a sign that your unit was installed incorrectly. Check the installation instructions in your manual, or call up a professional air conditioning installer to ensure your unit is secure. If you hear rattling noises instead, it’s possible that a screw or other piece has come loose inside the air conditioner, which you may be able to sort out on your own if you are able to dismantle your air conditioner.
Check for ice build up
If you notice weak cooling performance, there’s a chance that ice may have built up inside your air conditioning unit. Switch off your unit and lift the cover to see if any ice has built up behind the filter. If so, it’s time to call in a professional, as this will typically only occur if the fan blower belt is damaged.
The drain line of your air conditioner can also become clogged with dirt, dust and lint, just like your filter. If you see water leaking out of your air conditioner, it’s likely that the drain pan has filled up, meaning it needs to be emptied in order to prevent damage to your air conditioner or surrounding items.
Schedule your annual checkup
It’s all too easy to forget having your air conditioner checked out every year. We recommend having your air conditioner inspected shortly before summer to catch any major issues before they worsen, or before you really need your air conditioner at the peak of summer.
