How Often Do I Need HVAC Coil Cleaning in Greenville, SC?


Dirty coils prevent your air conditioner from working properly. To ensure the unit operates efficiently, have the coils cleaned at least once a year. Otherwise, your HVAC system is at risk of breaking down. We recommended scheduling an annual HVAC coil cleaning in Greenville, SC, in the spring.

Should My HVAC Coils Be Cleaned More Often?

Most systems require a coil cleaning just once a year. But if your unit operates in a particularly dusty or dirty environment or there’s heavy air pollution in your area, the buildup may form faster. Therefore, you’ll want to clean the AC coils more frequently. Pay attention to how your AC is working. If it’s not running efficiently or providing enough cool air, the AC coils may need to be cleaned.

What Types of AC Coils Need to Be Cleaned?

An air conditioner has an evaporator and condenser coils. The inside AC unit contains the evaporator coils that remove heat and humidity. Within the outside unit are the condenser coils that transfer heat to the outdoor air. Together, these coils allow the system to remove heat from the air in your home, but only if enough surface area is available.

Why AC Coils Must Be Kept Clean

An air conditioner absorbs heat thanks to the refrigerant circulating through its coils. This coolant cycles from a liquid to a gas and back in a repeating cycle. As it becomes a gas, it absorbs excess heat from the air that passes over the evaporator coil. It’s pressurized in the compressor and releases heat as it converts from a heated gas into a liquid. This heat exchange process requires that the coils be clean.

When an AC coil is dirty, its surface area is restricted. It will be unable to absorb or release heat. The system will work harder to cool the air and reach the desired temperature. It will also use more energy, so your utility bills will be higher. Inhibited heat exchange can also cause the system to overheat, eventually causing your AC to break down or fail prematurely.

Can I Clean My HVAC Coils?

It’s best to hire a professional for HVAC coil cleaning in Greenville, SC. The metal tubes are quite delicate and can be damaged under pressure. Repairing or replacing AC coils is expensive.

But if you’re confident enough, you can wash away dirt and debris. Only do so if this is routine for you. If the coils haven’t been cleaned in a while or the buildup is extensive, hire a professional.

Once you access the coils, you can wash them down with a hose. Use just enough pressure to push the dirt and grime off the surface. While you’re at it, trim back trees and shrubs so they’re less likely to cause rapid buildup on the coils.

For indoor coils, use a spray bottle to avoid puddles under the unit. Spraying compressed air can also help clean the coils. There are also non-acidic coil cleaners you can buy. If using a foaming HVAC coil cleaner, spray it directly onto the coils until they’re fully coated. The foaming process lifts off dirt and grime. Wipe or rinse off the cleaner after a few minutes, as specified by the instructions.

Why Should I Hire a Professional?

Hiring a professional for HVAC coil cleaning in Greenville, SC, saves you time and money. They have the training and equipment to do the job correctly. The coils will be cleaned thoroughly so your AC unit doesn’t have to work as hard. In the long run, you save because proper maintenance reduces the need for repairs and can help your HVAC system last longer. A technician will also inspect the unit and make minor repairs or adjustments to ensure it works at full capacity.
