The answer to 'how long will installation last' is that the installation time for a new HVAC system can vary widely depending on the size and complexity of the job. On average, a typical central air conditioning or furnace installation can take between 4-8 hours for an experienced HVAC technician to complete. However, more complex installations like ductwork modifications or zoning systems may take 1-2 days or longer.
The installation process involves several key steps: assessing the existing system, determining the right new equipment size, running new or modifying existing ductwork, installing the indoor and outdoor units, connecting electrical and refrigerant lines, and testing the system. Factors that can impact the timeline include the accessibility of the work area, whether any structural modifications are needed, and the availability of the specific equipment being installed.
