Could strange noises indicate AC issues?« Back to Previous Page

The AC unit in my living room has been making this strange humming noise for days now, especially during the evenings when it’s really humid. We’ve only had it for a year but I’m starting to think it might need professional attention since it’s been acting up more frequently. Should I just call someone or could this be something simple I can fix myself?

Absolutely, unusual noises from your AC unit can indeed signify underlying issues that may require attention. In the UAE and particularly in Dubai where humidity levels are a bit higher, it's crucial to keep an eye on any changes in your air conditioning system.

Firstly, let's discuss the humming noise you're experiencing. This could be due to a few reasons - perhaps the unit is improperly installed or there might be some loose components inside that need tightening. It’s also possible that the motor is malfunctioning, which can happen even within the first year if it wasn't properly maintained.

In Dubai, as in many other cities with stringent building regulations, ensuring your AC system complies with local standards such as EN 457 (European Standard for Air Conditioners) and EN 12831 (Air Conditioning Equipment) is paramount. However, the specific UAE Building Code may also have additional requirements that your unit must meet.

If you’re noticing this noise predominantly during humid evenings, it could be because of excessive moisture or poor drainage within the system. Condensate lines should be checked for blockages or leaks to ensure they are functioning correctly. Improper handling of condensation can lead to mold growth and other health issues, which is why we recommend checking for any signs of moisture damage.

Given that you’ve only had this AC unit for a year but it’s acting up more frequently, it might be wise to schedule an inspection with a professional company like ours at Saniservice. We offer comprehensive air conditioning maintenance services in Dubai and the UAE, ensuring your system operates efficiently and safely.

Remember, while some minor adjustments may resolve the issue, serious problems such as electrical issues or refrigerant leaks require expert handling. Regular servicing can help prevent these types of issues from escalating into more costly repairs down the line.
