Air ducts are one place where small particles such as pollen can get indoors from outside.
One of my clients, arman, that do duct cleaning vancouver wanted to share the following thoughts..
The EPA suggests that air ducts should be cleaned if there is mold growing in them, they are infested with bugs or rodents, if they are clogged, or if viable particles are being released indoors.
Particles that are stuck in the HVAC system may be a result of dirty air ducts. Moisture can also get into this system which can cause mold to grow. There is potential that mold spores can be released into the air. The manager of the facility must ensure that the air ducts are cleaned on a regular schedule.
There are some suggestions from the CCA to keep dirt out the air ducts system.
Be sure to change the filters on a regular basis especially if they are clogged. Use high efficiency filters that come recommended by HVAC or duct experts.
Be sure that no filters are missing and there are no gaps in the system. When having an HVAC service be sure the cooling coils and drain pans are cleaned. When having any HVAC work done seal off the registers and do not use the system until the work is completed.
Vacuum regularly with a HEPA duct cleaner vacuum.
Use any in duct humidifier according to the institution by the manufacturer.
To Prevent Wetness:
Repair any leaks right away.
Inspect the cooling coils on a regular basis. They are susceptible to mold growth.
Be sure the condensate pan drains properly and there are no wet spots.
Make sure all ducts are properly sealed.
Select an air conditioning system that is the proper size and seal all ducts and joints.
