Be cautious with companies that offer “whole house air duct cleaning,” urges the NADCA. The company may be using unscrupulous tactics to upsell you once they get started. Before any work begins, always clarify in writing what the job entails and what the cost will be. To protect yourself against fraud, read customer reviews and verify that your HVAC cleaning service has applicable licenses and certifications.

Another valuable service that can be offered to you after the HVAC system has been cleaned is anti-microbial fogging. The name of this service is impressive, but the service itself is quite simple. A small chemical fogger is used to introduce chemicals into the ductwork system, chemicals that sanitize germs, bacteria and fungus. EPA-registered chemicals specifically for use in ductwork systems are available that do not require the evacuation of family members and pets from the occupied space while the chemical is being used. We simply add the liquid chemical to the fogger, and fog the supply ducts before replacing the registers. Then turn the central fan on, and fog through the return duct, with the HVAC system's fan helping to distribute the chemical throughout the system. The best news is that fogging can be repeated every 6 months, while system cleaning is at best required every couple of years. Antimicrobial fogging is a simple service that provides real benefits to our customers.

Nowadays most houses have a central air conditioning system linking air ducting to move conditioned indoor air throughout the house. Gradually, the air system and the linking air ducting will collect dust and other contaminants, which can trigger the blood circulation of unclean and contaminated indoor air through your house. Out-of-sight and out-of-mind health products that we do not believe much about are filthy air system and a duct which could be the unhealthiest product in our house.
While a thorough air duct cleaning process must be done by professionally qualified service companies, there are a few steps you can take to help maintain the cleanliness of your heating and air conditioning system. One is to change your air filters regularly and make sure you have the right filters for your home and HVAC system. You should also have your system professionally inspected every one to two years to have a technician determine if your air ducts need to be cleaned. In between scheduled maintenance or inspections, you can do a visual check yourself by removing a wall or floor register and shining a flashlight inside the duct. If you can see debris, dirt or dust, it’s time to have your ducts cleaned by a licensed, insured HVAC professional.
