Should I repair my AC or call a pro?« Back to Previous Page

The AC in my living room has been making this strange humming noise ever since we replaced it last summer, and now it’s not cooling as effectively as before. Given how hot it gets during the summer months, I’m worried about handling any repairs myself. Do I need to call a professional, or can I do some basic troubleshooting on my own?

Absolutely, the humming noise and reduced cooling efficiency of your air conditioning unit definitely warrant attention. In Dubai/UAE, given the extreme summer temperatures, it's crucial to ensure that your AC system is operating efficiently and safely.

Firstly, it would be wise to perform some basic diagnostics on your own. Start by checking if the power supply is stable, ensuring there are no issues with the circuit breakers or fuses. Additionally, inspect the filters for any dirt accumulation - a clogged filter can lead to poor performance and unusual noises as the unit struggles to push air through.

If these initial checks do not resolve the issue, it's highly recommended that you contact a professional HVAC service provider. The UAE has specific regulations regarding air conditioning systems, particularly those related to energy efficiency and safety standards. Ensuring your AC is in compliance with these guidelines can prevent potential hazards and ensure optimal performance during peak summer months.

When reaching out to a professional, be prepared to provide details about the issue: the type of unit you have (split system, central AC, etc.), the brand, any recent changes or modifications made, and the specific nature of the problem. This information will aid the technician in diagnosing the issue more efficiently.

A few things worth noting:
• Regular maintenance is crucial for longevity and efficiency.
• Dubai’s summer months can see significant temperature variations, so a well-maintained AC unit will perform better overall.
• Do not hesitate to ask about the specific certifications or licenses held by the technicians performing the service. In Dubai, it's common to have professionals who are certified in both HVAC services and refrigerant handling.

Remember, while DIY fixes can sometimes solve small issues, more complex problems often require specialized tools and expertise that a professional can provide. If unsure, always err on the side of caution and contact an expert to avoid potential damage or safety risks.

In conclusion, given your concerns about efficiency and noise, it's advisable to schedule an inspection with a qualified HVAC technician. For assistance, you can call 800-MOLDS (800-66537) or email hello@saniservice.com for further guidance and booking of services.

Stay cool in the UAE!
