Why is Coil Cleaning Such an Important Service?

Your air conditioner (and your heater, if you have a heat pump instead of a furnace) relies on two different coils to keep you cool, dry, and comfortable. These coils have one primary job: to facilitate the heat transfer which cools the air. By the very nature of their work these coils can get dirty over time. When they get dirty, they need to be cleaned in order for your air conditioner to work properly. However, we’ve found that far too many people don’t get their coils cleaned as often as they should, and this could mean a number of consequences on their system.

In this blog, we’ll explore what dirty coils can do to your system as well as a few of the reasons why regular coil cleaning should be an important part of your annual HVAC maintenance services.

Insulating Your Coils

As we stated previously, the primary function of your coils is to facilitate the transfer of heat between the refrigerant in the coils, and the air that’s passed over time. Inside your home, your evaporator coil is responsible for absorbing heat out of the air. This produces the cold air that your system then blows back into your home to keep you cool. Outside your home, your condenser coil’s job is to expel the heat from your refrigerant into the air, thus cooling the refrigerant inside so it can be used to absorb more indoor heat. This means in order to be the most efficient, your coils need to be clean and capable of passing heat as quickly and effortlessly as possible.

However, when your coil gets dirty, the dust and dirt that accumulates on the outside acts like a sort-of blanket. The thin coating prevents the heat transfer from happening as efficiently as possible, and thus prevents your HVAC system from working as well as it should. When the heat can’t transfer properly, less heat will be absorbed from the air in your home, which means the air coming out of your air conditioner will actually be warmer. Outside, it means that less heat can escape from your refrigerant, which also contributes to warmer air in your home. Both of these combined mean longer cycle times, added strain on your HVAC system, wear and tear on components, and more breakdowns that require costly repairs. It also contributes to higher energy bills that suck more money out of your pocket.

How to Keep Your Coils Clean

There’s no escaping it—over time and repeated use, your coils will eventually grow dusty and need cleaned. This is normal, and we strongly advise you to do so roughly once a year (usually around spring time, right before you have to fire up your air conditioner for the first time). A coil cleaning service can be obtained by calling a professional Palm Beach County HVAC company, and it can usually be added on to a general maintenance service for your system.

However, it’s also important to do what you can to help keep your coils clean. Your outdoor coil in particular has a difficult time because it’s not protected from dust and other debris. The air that’s pulled into your outdoor system is not filtered in any way—it simply gets pulled through the cooling fins and over your coil to remove heat. So naturally, it’s best to try and keep the air coming through the coil as clean as possible. While you can’t do a whole lot about the air quality, you can do your part to keep sources of dirt and dust away. Keep any plants and bushes trimmed back to a radius of at least three feet around your out door unit, including cutting any grass that may be within that area. And likewise, be sure to sweep the area clean if any dust or dirt settles around it.

Your indoor coil has it easier: it’s naturally protected by your HVAC air filter, and the air that passes over it has already been strained to remove the majority of the dust and other airborne contaminants. Some will still get through, however, and holes in your HVAC unit can also allow additional pollution to sneak in. The best thing you can do to keep this coil clean is regularly keep an eye on your air filter and change it as often as necessary. A clean air filter will strain more debris out of the air, while a dirty one will both bog down your system and allow more dust and debris to come through.
