Study Finds That HVAC Coil Cleanings Can Save Energy

While HVAC professionals have always known that dirty coils severely reduce a heating, ventilation, and cooling system’s efficiency—ASHRAE’s recent study on a landmark New York City building confirms that HVAC coil cleanings save energy.


Energy savings translate into financial savings for your business. In addition to the “hard findings” of the study, ASHRAE concluded that HVAC coil cleanings offer a number of other benefits, such as:

  • Increased airflow and HVAC efficiency
  • Improved indoor air quality (IAQ)
  • Higher levels of comfort and satisfaction among tenants
  • Increased productivity of employees
  • Lower utility bills
  • Dirty and blocked coils are some of the most common problems with heating, ventilation, and air conditioning systems—and could cost your business thousands of dollars a year.

Clean Your Commercial HVAC Coils With Routine Maintenance

A poorly maintained evaporator coil decreases airflow due to a buildup of dust and debris, causing a change in the coil temperature. The build-up forces the compressor to work overtime, leading to increased energy consumption, higher utility bills, and decreased HVAC system efficiency.

Left untreated—dirty, blocked coils can be fatal to your HVAC system and result in everything from ice on the evaporator coil to an overheated compressor to total system failure. According to the Department Of Energy: “a dirty condenser coil can increase compressor energy consumption by 30 percent.”

One of the simplest and most cost-effective steps you can take to maximize your system’s performance and increase your building’s energy efficiency is to have your HVAC system’s coils inspected and cleaned.

It is recommended that you have your HVAC coils professionally cleaned at least once a year—so why not do it now to prepare for the cooling season?
