Typically we suggest a homeâs air ducts be cleaned every five to eight years. Homeowners with children, pets, respiratory issues or a compromised immune system may want to get their HVAC duct system cleaned more often. The better filtration the system has cuts down on cleaning frequency.
Cleaning air ducts makes a lot of sense, at least in theory. Because dust gradually accumulates on virtually every surface, doesnât it stand to reason that it would build up to an intolerable degree in the mostly untended HVAC ductwork that runs throughout your home? Yes, air ducts get dusty.our furnace or air conditioning filters trap a high percentage of particles in the air, preventing them from entering the ductwork. Surely, thatâs a reason to clean or replace your HVAC filters on a regular basis, but itâs not a strong argument for taking any further action. 2.
