With colder weather upon us many of our customers look to have duct cleaning completed in the fall and winter months. Furnace and duct cleaning can address indoor air quality issues by removing dirt, dust, pet hair and dander from your heating system. Left unchecked you may be breathing in these harmful particles when your heating system comes on. Mold contaminants may cause breathing difficulties or allergic reaction for some people. We recommend cleaning your hvac system every 2 years to maintain optimum air quality in your home. A complete and thorough cleaning requires that all vents and cold air returns be cleaned at the same time. As First Call always wants to do a thorough and complete job, we require that each vent and cold air return be cleaned at one duct cleaning.
