Make sure that the company has the proper equipment and enough HEPA filtered vacuum power (2,000 CFMs or more), to properly clean your air ducts. Be weary of companies that use small vacuum units that have a small rotating brush on the end of a small vacuum hose with a typical airflow of 150 to 300 cfm or less. Proper air duct cleaning vacuums are negative air machines with 2,000 CFMs have 8 inch to 14 inch or larger, vacuum hoses to capture large quantities of dust and debris.
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.
Air McCall’s comprehensive Duct Cleaning process includes the use of a fogging machine to sanitize your duct system with an all-natural biocide that is harmless to you and your family, and your pets as well. Most companies use a sprayer (not a fogging machine) to try to sanitize the duct system but the sprayers are not effective to treat the entire duct system.
Clean air ducts are an important component to having a clean home, and therefore it can be a great idea to clean your vent system. For maintenance purposes, we recommend that your air duct and vent system be cleaned every 3-5 years, depending on a variety of factors including your personal preference, number of pets in the household, cleanliness of the household, and other activities that affect indoor air quality, such as smoking inside. Air duct cleaning is also a good idea at the completion of a remodeling project, when moving into a new home, or if you experience increased allergies.
If you’ve been noticing more dust around the house or worsened allergies, it may be time to have your air ducts cleaned. While it’s recommended to change your air filters regularly, professional air duct cleaning only needs to be done once every five to seven years. More effective and prolonged results from air duct cleaning can be attained by having a whole-home air cleaner installed.
Negative pressure air duct cleaning is a process in which the ducts are cleaned by hand in concert with compressed air tools to dislodge dirt and debris, which is then vacuumed up and removed. It is considered a superior cleaning method in its efficiency and in preventing dislodged debris from escaping the ducts and contaminating the air in the residence.
On the other hand there are many more air duct cleaning companies that will properly clean the air system and air ducts and use commercial negative air duct cleaning vacuums with at least 2,000 CFMs of vacuum power and utilize proper agitating tools to move the contaminates within the duct work to be captured with HEPA filters and contained by the air duct cleaning vacuum equipment.
