It’s that time of year again:  Spring Cleaning! When cleaning your home (or thinking about cleaning your home…), you should also consider cleaning your ducts. Duct cleaning helps to clean out and sanitize dust, mold, pollen, and other small particles. Typically ducts should be cleaned every 3 to 5 years; however, there are some reasons they should be cleaned more frequently.
For example, if you have pets that shed excessively, if people in the house smoke, or if you are moving into a new house.
FLAME Heating, Cooling, and Electrical offer certified NADCA (National Air Duct Cleaners Association) technicians to inspect, clean, and sanitize your ducts. They can also install UV Germicidal lights that kill irritants and that help to keep your ducts clean!
