A commercial air handler cost is the total cost associated with the purchase and installation of an air handler unit for a commercial building. An air handler is a large metal box that houses the components of a heating, ventilation, and air conditioning (HVAC) system. It is responsible for circulating air throughout the building, controlling the temperature and humidity, and providing ventilation. The cost of a commercial air handler can vary greatly depending on the size and complexity of the unit, as well as the installation costs. Generally, the cost of the unit itself can range from a few hundred dollars to several thousand dollars, while installation costs can range from a few hundred dollars to several thousand dollars. Additionally, the cost of any necessary maintenance or repairs should also be taken into consideration when determining the total cost of a commercial air handler.
