The Importance of AC Coil Cleaning

Summer residents of Dubai know the horrors of a broken AC to its full depth. It leaves you exhausted and struggling to do the smallest thing and poses severe dehydration risks alongside. Considering the importance of air conditioning units everywhere, but especially here, we have compiled a list of why AC coil cleaning is as important as breathing in this sizzling city.

Firstly, we know we don’t need to go into this a lot, but it is tremendously important to keep up with your AC maintenance. Your heating, ventilation, and air conditioner system, commonly called HVAC serves a surprising number of features, protects you by regulating your body temperature during extreme weather, and prevents diseases. Ironically, a poorly maintained AC can become the source of a pervasive low-level respiratory disease year-round. It can affect you and your family in subtle ways and seriously hinder your overall immunity and health. Added to that the fact that a badly kept AC slims down your wallet an awful amount. Why? Because an overused air conditioner rakes up higher DEWA bills than a smoothly functioning one. 

Following an AC maintenance guide can keep your AC going for several years, offering help with initial checks that prevent deeper problems from arising. However, while this may be a useful way to keep minor problems in check and ensure the basic cleanliness of the external unit, we strongly recommend getting a professional in to take an in-depth look and handle actual long-term maintenance for you. That way, the performance of your HVAC unit is guaranteed for a longer period of time.

It’s a great idea to look at the separate components of an AC in order to better understand where potential issues might crop up and why these are more likely than others. In this blog, we will be focusing on air coils that absorb heat from your home and expel it, called coils.

What do Air Conditioner Coils do?

Your air conditioner unit’s coils can be broken down into two types; the condenser coil (Outdoor) and the evaporator coil (indoor). 

They work in tandem to create one fully functional system by using refrigerant to regulate the temperature as it exudes heat and converts it to cool air. The evaporator coil works to absorb the heat and humidity that your home environment contains. It is located in the indoor facing part of your HVAC, in the air handler unit. The condenser coil works to expel that accumulated heat to the outdoors and is located in the outdoor portion of the AC. A problem in your coils starts when dirt, dust, and debris begin to accumulate in your coils. The extra layer of grime atop your coils works like an insulation blanket. Picture a hot oven dish containing freshly baked goodies. You use oven mitts as you remove them because the mitts act as an insulator that protects your hands from the searing heat. Similarly, the layer of dirt prevents the cold of the insulator from effectively cooling the air it expels into your room by absorbing it into itself. It also hinders the adequacy of the heat transfer and drastically increases your unit’s run time in order to achieve the same degree of cooling that a well-maintained AC would deliver in the same time. This reduced efficiency of cooling cycles forces your air conditioner to run with more pressure for longer, skyrocketing your DEWA bills, but achieving little else in the process.

Grimey coils in your HVAC system lead to numerous troubles. They can appear in the form of decreased cooling, as we mentioned above. Another concern most people with clogged coils face is increased wear and tear on their air conditioning unit, which not only shortens the unit’s lifespan but can result in astronomically expensive repair bills in the future. 

How do coils get dirty?

Every tiny speck of dust, small chunks of debris, hair, and fur has the potential to add to the grime that slowly but steadily clogs your air conditioner. If you live in Dubai, chances are that your outdoor unit is located near a street and consistently faces exhaust fumes that form a soft base for your other pollutants to settle on. We cannot discount the all-pervasive sand that amasses steadily in every small nook and corner of Dubai. Sand has the distinction of being present in your AC’s indoor evaporator coil as well. Depending on the presence and quality of the air filter, it is joined by a stream of household contaminants, such as fur, dust, and small dead insects. 

So how much dirt has to gather before it starts to seriously hinder your HVAC’s cooling? The dire news is that a minuscule amount like 1/100th of an inch of debris and dust is enough to drop your unit’s performance by as much as an astonishing 5%. And it’s downhill from there, as the coils of the average person’s cooling system rarely get more than the occasional checkup or cleanup.

Coil Cleaning Process

We strongly recommend you to request professional coil cleaning every 1 – 2 years. To begin, unlock and remove your unit’s outer case or panel. Once they’ve been removed and you can see the coils, use a brush to gently and firmly brush off the debris. This goes a long way in between your scheduled maintenance. A clean AC is not invaluable only because you can calculate exactly how much money you’d save by avoiding expensive repairs and replacements. This is a great opportunity to take a look at your coils and ascertain if they’re in good condition. That being said, we always recommend that you leave AC maintenance and repairs to a specialized expert since it requires training and knowledge that most people lack, and you can end up accidentally damaging it instead.
