The Importance of Cleaning Coils

Air Conditioning Units on Exterior of Building

Making sure you’re ready to beat the heat is essential in this weather. That’s why we at Surrey Air recommend checking and cleaning your system’s coil regularly to ensure your air conditioning unit is working properly.

What is a Coil?

Coils are used to transfer heat out of or into an airstream. They are one of the most important components of your unit.

Over time the surfaces of these coils can become dirty as the air moving over the coils can contain dust, dirt, pollen, moisture and other contaminants. A build-up of contaminants decreases the available surface area for heat transfer, reducing the

The efficiency of the heat transfer process, leading to excessive energy consumption and poor system performance.

It is important that air conditioning coils are regularly inspected and maintained to ensure they operate at optimum efficiency.

In addition to the energy efficiency and system performance benefits, regular coil cleaning also improves the life span of your unit and indoor air quality. Surrey Air offer maintenance and system testing services to make sure your coils are clean working as they should.

Important Facts

Keeping the coil in your unit clean has an array of benefits, here’s how proper servicing can help you keep cooler and wealthier:

  • A dirty condenser coil can increase compressor energy consumption by 30% according to a US Department of Energy report.
  • A rise of 5 degrees as a result of dirty coils can cut cooling capacity by 7% and increase power consumption by 10%. Imagine how that could increase your energy bills over the course of a year…
  • The hotter the outside temperature gets the higher the load on your unit with dirty coils which ultimately reduces its capacity to function and could result in failure of your unit.
  • Poorly performing coils make the other components in your unit work harder for longer resulting in reduced life cycles.

Act Now

It’s not too late to make a difference. Typically we can achieve a 10% energy saving after cleaning a coil that has not been inspected in the last three years.

Our technicians will give your unit a visual inspection and measure the difference in temperature between air entering and air entering the coil. Because coil cleaning can involve the use of compressed air and the removal of biological contaminants it should only be undertaken by experienced service providers.
