Reasons to Clean Coils
Four Step Solution
Step 1 - Clean
Clean indoor (evaporator) and outdoor (condenser) coils with quality products that are designed to restore original BTU output and improve airflow.
Step 2 - Protect
Apply an EPA-registered product to the evaporator and condenser coils to repeal dirt and keep the coils cleaner longer.
Step 3 - Kill Bacteria
Kill bacteria on evaporator coils, drain pans and duct-work. We use a product that is an EPA-registered product that's a bacteriostat, fungistat and deodorizer. This prevents future biological growths and the odors they cause.
Step 4 - Prevent
Place an EPA registered drain pan biocide, in the evaporator drain pan. This prevents biological growths and slime. This protection will last up to 6 months.
Coil Cleanings
When a coil becomes fouled with dirt and grime, it cannot provide adequate or
designed heat transfer causing higher discharge pressures. The higher discharge pressure requires
more electricity. thereby, increasing the costs for operating the equipment. The energy consumption
of equipment operating with dirty coils can be as much as 37% more than that used by equipment with
clean coils.
For example, a typical 10-ton air conditioning system operating for an average cooling season of 1,500 hours, with clean coils, will cost approximately $1,650 to operate. However, when the coils become dirty, the six-month cost could escalate to $2,268. a 37% increase or a $618 savings by keeping the coils clean! A typical 4-ton residential unit would realize a $248 savings.

As the dirt and grime collect on the coils it restricts heat transfer causing the compressor to
work harder. This adds more heat to the system and raises the head pressure as much as 75%.
Higher head pressure can result in a loss of up to 30% of the system's cooling capacity.
This loss will be most noticeable on the HOTTEST DAYS when cooling is needed the most!
Higher operating pressures and temperatures caused by dirty coils can reduce the equipment's life
expectancy. The elevated system pressure and temperature can lead to the breakdown of the compressor's
lubricant. In addition acid formation can occur, leading to an acid burnout. Lubricant breakdown
and acid formation will seriously comprise the compressor and ultimately lead to equipment failure.
Compressor failure means NO COOLING. No cooling means no comfort. And, a compressor replacement
means a costly repair.
The evaporator, or inside coil, presents major concerns that go beyond the issues already discussed.
A fouled and dirty evaporator coil creates a breeding ground for bacteria and mold that can impact
the indoor air quality. Cleaning, protecting the coil and preventing bacteria growth on the
evaporator coil and surrounding areas is critical. Specific cleaners and products will be required
for these applications.
