Technical Corner: Benefits of HVAC Sanitizing

Cooling coils require clean coil fin surfaces to cool the air. But they become coated with films of bacteria and fungus. These biofilms insulate cooling coils – it’s like putting a winter coat on in the summer time. Your unit just has to run longer to cool the air.

It is common for interiors of air conditioning equipment to develop bacteria and mold growth. These are not only a source for allergens for people, but create other problems as well.

Actually the buildup of microorganisms in air conditioning equipment is much greater than most people recognize. It can be quite significant, and effect not only building occupants but the cash flow of commercial buildings.

Cooling coils require clean coil fin surfaces to cool the air. But they become coated with films of bacteria and fungus. These biofilms insulate cooling coils – it’s like putting a winter coat on in the summer time. Your unit just has to run longer to cool the air.

Of course, longer running of equipment means using more electricity – as much as 40% more according to the ASHRAE Journal.

Since the HVAC system uses about half of all electricity consumed by a commercial building, periodically removing bio films from coils is financially beneficial for the building owner.

In addition to wasting electricity, another unfortunate fact is that fungus and bacteria grow quite well in the dark and damp interior environments of air conditioning equipment. Growth occurs in such quantities that even half-inch drain lines can get completely plugged up with slime, resulting in expensive condensate pan water overflows.

Along with the growth of fungus and bacteria, foul smelling odors are emitted by decaying microorganisms. Moldy smelling units are dirty, biologically contaminated units.

But there is a way out of this.

Using Fast Attack HVAC Sanitizer quarterly can do much to reduce or eliminate these microbes and the decrease of efficiency they cause. It’s easy, and cost-effective to use. You’ll be glad you did.
