When cleaning your AC system, don’t limit it to the ducts alone, rather you should clean the entire thing.

Failure to do this would result in contamination of the whole system thus causing lower performance efficiency.

Some of the components that need to be thoroughly cleaned include the following.

a) Drain pan

b) Coils

c) Air ducts

d) Grills

e) Registers

f) Blower motor and assembly

g) Air plenum

h) Heat exchanger

i) Air cleaner

j) Air filter

During the cleaning process, you need to remove the contaminants and also collect them to increase the efficiency of your system.

1. Removing The Contaminants: Here, you need to remove all the available sources of contamination in the unit. Start by using agitation devices that break the contaminants loose from the surfaces of the HVAC system. Some useful agitation devices include air whips, brushes, skipper balls or compressed air nozzles. With contact vacuuming or hand-brushing, you can also remove the contaminants making the loose completely.

2. Collecting The Contaminants: When cleaning the HVAC system, you need to place it in a vacuum (continuous negative pressure) to prevent the contaminants from spreading. Here, the particles can be removed from the system carefully before they get into the living space, especially when the system is turned one. On the other hand, any loosed contaminants will be collected carefully then removed from your home entirely.

Accessing The System

Cleaning your HVAC system is not complex but each task might be unique. If possible, you need to access the duct interiors through the supply diffusers, duct end caps, return grills and any other service openings. Professional HVAC maintenance experts might cut holes in the duct work to access the system properly with their cleaning tools but you shouldn’t attempt it on your own without the proper professional skills.

Equipment Requirements

HVAC cleaning experts have access to various cleaning tools and equipment. With portable vacuums and truck-mounted options, they can prevent the contaminants from spreading to your living space. These professionals use the appropriate cleaning standards for the best results.

Antimicrobial Chemicals

These include disinfectants, sanitizers and deodorizers. They are often applied to the HVAC non-porous surfaces to prevent odors and attack any microbial contamination. These chemicals should be registered with EPA to prevent further contaminates or reactions. Only use these chemicals once you have cleaned the mechanical surface and if further cleaning is required.

Whenever you’re in doubt about your HVAC system cleaning, it’s best to leave it to the professionals. Your installation team should have maintenance services which they can offer whenever required. Therefore, when choosing a good HVAC installation team, find out when they can offer maintenance services and make an appointment to avoid any inconveniences.
