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.
Fortunately, hiring a professional cleaning service is much more affordable than you might think. While the specific cost will vary depending on how many vents and ducts you have in addition to their size, most home and business owners can have these services performed for about $150 to $400.n general, it should not take more than 3 to 5 hours for the cleaners to get the job done. During this time, they will use a series of tools to clean out all the ducts and vents within your home or place of business. By having this type of work done, you can notice an immediate improvement in your home's air quality.
