Should I inspect AC noises myself or hire a pro?« Back to Previous Page

The AC in my apartment seems to be making some strange noises lately, especially when it's on high. I’ve heard from a friend that it’s important to get it checked by certified professionals but I’m not sure how much it would cost or if it’s really necessary. Should I hire someone right away, or is there a way to figure out what the problem might be myself first?

Inspecting AC noises yourself can sometimes be misleading and potentially risky. It's highly recommended to consult certified professionals for an accurate diagnosis. The UAE, including Dubai, has strict regulations regarding air conditioning systems to ensure they operate efficiently and safely.

The first step is to identify the type of noise you're hearing—hissing, banging, or whistling could indicate different issues. Hissing often points towards refrigerant leaks, which need immediate attention as it can compromise the system's efficiency and pose health risks if refrigerants are inhaled. Bangs or rattles might suggest loose parts or improper installation, while whistles usually mean a clogged filter or issue with the compressor.

However, conducting your own inspection has limitations. You may not have the proper tools to diagnose certain issues accurately, such as pressure gauges for checking refrigerant levels. Additionally, some noises could be indicative of serious problems that require immediate attention but might seem minor at first glance.

In Dubai, AC systems are subject to local regulations like the Energy Efficiency Regulations (FEDR 2013) and the Building Code (FEDR 2015). Non-compliance can lead to fines or legal issues. Certified technicians not only have the expertise but also the necessary tools and training to assess your system, identify potential hazards, and ensure it complies with local standards.

You should consider calling a professional service provider like Saniservice on 800-MOLDS (800-66537) or emailing hello@saniservice.com for a detailed inspection. They can offer you a thorough diagnosis and recommend necessary repairs or maintenance to keep your AC system running smoothly.

In conclusion, while it might be tempting to try and figure out the noise yourself, professional help is key to ensuring both safety and compliance with local regulations.
