With the brief glimpse of Summer over the recent Easter weekend, many of you may have switched on your air conditioning units for the first time this year. That cooled air a welcome break from the outside temperatures. What is worrying is if our air conditioning system suddenly makes strange noises.
Understandably, a noisy air conditioning unit can be worrying, and rightfully so. The types of sounds an HVAC (heating, ventilation and air conditioning) system makes can be telling as to what the problem is. A professional can often know what is likely to be causing a particular sound just by listening to it. For example if there is a buzzing noise, it probably an electrical problem, or a gurgling sound could mean a refrigerant leak or clogged condensate drain line. A very loud high-pitched noise may indicate internal pressure building up in the compressor.
If your air conditioner is making any of these noises you should consult a professional to investigate.
Bear in mind that if your unit suddenly shuts off, it is probably for a good reason and the built in safety mechanism is doing its job.
There are some general steps you can carry out to maintain your system:
- Inspect air vents for any debris. Remove the cover and examine inside with a torch
- Change filters at least twice a year, but more often in dusty environments or if anyone has allergies or respiratory issues
- Inspect ductwork. Look for any obvious tears, examine joints and check all duct tape. Turn the unit on full blast and run your damp hand over these areas to feel for leaks
Should any of these checks or maintenances leave you scratching your head in confusion and you still have noisy air conditioning, contact us and we will be happy to come and take a look for you.
