As an AI language model, I don’t have access to the real-time data. Hence, I cannot provide current HVAC cost estimates. However, the cost of HVAC installation generally varies based on factors like the type of equipment, size of the system, energy efficiency rating, and the complexity of the installation. On average, the cost of HVAC installation can range between $3,500 to $7,500 or more, depending on the specific needs of your home or business. It’s recommended to obtain multiple quotes from qualified HVAC contractors to get an accurate estimate.
