A typical HVAC system costs between $500 and $5000, depending on the size of the home and the type of system.
For a single-family home, a basic HVAC system will typically cost around $500-$1500. If you want a more premium system, such as a geothermal or energy-efficient model, you can expect to pay upwards of $2000. If your home is very large or has specialized needs (like an underground room), your HVAC installation may cost as much as $5000.
