Air conditioning (AC) is certainly essential in every Dubai house and office, thanks to the burning hot weather in the region. But your AC unit, like any other mechanical product, requires regular maintenance in order to operate with maximum efficiency. One of the important ones is AC coil cleaning, which can dramatically affect both the performance and the longevity of your system.
Is AC coil cleaning inside indeed necessary? The answer is yes! Wipe down the coils inside and outside
Before we get into the specifics of cleaning AC coils, it’s important to understand what AC coils are and how they work. There are two types of coils in your air conditioning unit:
The evaporator coils are situated in the air handler of your air conditioning system, often found within the furnace or air handler units. These coils absorb heat from the indoor air and transfer it to the refrigerant which cools down the temperature. The condenser coils, which are situated outside, discharge the extractable heat to the outside.
Both component parts operate together for effective cooling, however, greater care to the evaporator coils are required because inside the system they are more susceptible to dirt and mold buildup.
The importance of cleaning the inside AC coils cannot be overstated. Over time, dust, dirt, and other contaminants accumulate on the coils. This not only affects the AC’s ability to cool the air effectively but also leads to:
Decreased Cooling Efficiency
Buildup of dirt on evaporator coils inhibits heat absorption. As a result, your AC has to work overtime to cool your house which increases energy consumption and electricity expenses.
Frozen Coils
Dirt buildup prevents air from dynamically moving through the evaporator coils which can cause the coils to freeze. This will result in a complete breakdown of your AC system.

Decreased Lifespan of your AC
Early wear and tear as a result of not regularly maintaining your AC unit (such as coil cleaning) increases the chances of costly repairs or replacements.
In a city such as Dubai, where the air conditioning unit is used virtually every day, the indoor AC coils should be cleaned at least once a year. Residents of dusty neighborhoods or those with pets will likely need to clean the coils even more frequently. Regular maintenance makes sure that your equipment is fully functional.
While it’s possible to clean the coils yourself, professional cleaning is often recommended for a thorough job. DIY methods may not get rid of all the dirt and mold, and you might risk damaging delicate parts of the system. That being said, if you choose to clean the coils yourself, here are the basic steps:
Hiring a professional AC technician ensures a more thorough and effective cleaning of the inside coils. An expert technician will:
Now that you know why it’s important, let’s dive into the benefits you can enjoy by keeping your AC coils inside clean.
Regular coil cleaning allows the system to operate at its optimum level, reducing the need for excessive power to cool your home. This can save you money on electricity bills, especially during the peak summer months in Dubai.
A well-maintained AC system provides better cooling performance, keeping your home comfortable even in Dubai’s extreme heat.
By preventing dirt and mold buildup, you can avoid major AC problems, saving you from costly repairs or replacement costs in the future.
A clean AC system improves the air you breathe, helping eliminate allergens, dust, and mold that can cause health issues.

Signs include warm air coming from vents, higher energy bills, or the AC unit not cooling as effectively. If you notice these issues, it's time to check the coils.
While you can attempt to clean the coils yourself, it’s recommended to hire a professional for thorough cleaning to avoid any damage to the system.
It is advisable to clean the inside coils once a year. If you live in a dusty area, more frequent cleaning may be necessary.
Cleaning the AC coils thoroughly is one of the most vital activities improved the performance, energy efficiency and life span of your AC unit. In Dubai, where air conditioning is indispensable for day to day comfort, ensuring the coils are clean is paramount. Be it a DIY cleaning job or hiring a professional, cash for cooling systems in the long term will always be a bang for your buck
