Coil cleaning is an important part of regular upkeep for any HVAC system. Coils are responsible for transferring heat from the air in a home or building to the refrigerant running through them, and if they become dirty, it can lead to problems with air quality and energy efficiency.

Regular coil cleaning can help prolong the life of your HVAC system, as well as save you money on repairs and energy bills by reducing resistance to air flow. The process should be done at least twice a year to keep up on general maintenance, though it may need to be done more often depending on how quickly the environment around your unit becomes dirty or dusty.

When it comes time for a coil cleaning, you have two main options: do-it-yourself using a foaming cleaner or hire a professional technician who can perform both chemical and mechanical cleaning methods.
