Microorganisms like bacteria, mold, mildew, fungi and yeasts occur everywhere in our environment. The moisture that forms in your air conditioner, including the duct work, cooling coils, drip pans and humidifiers create an ideal environment for the growth of these microorganisms. Left unchecked, they could be potentially hazardous to you and your families' health. Maintenance calls include changing your unit's filter, cleaning the vent traps, sanitizing the coils and monitoring of the temperature.
