Large volumes of air are circulated around the home or business by air conditioner systems. This air travels via a handler unit’s evaporator and fan. This air movement may be impeded by dust and grime buildup in the ducting, which could result in inadequate circulation surrounding the evaporator and eventually freeze the coils. This obstruction keeps the refrigerant from returning to the condenser unit by making the system overwork itself. Improperly chilled air is the result, which is a nightmare for any resident in Las Vegas.
