What affects the price
When you look at the cost of a new HVAC system, several variables come into play. The size of your home and the necessary cooling or heating capacity—measured in tons—are the biggest factors. You also have to consider the efficiency rating of the unit, the complexity of your existing ductwork, and whether you need to upgrade electrical components to support a modern system. Labor requirements, including accessibility and permit fees, further influence the final number.
About this service
A mini-split installation involves mounting an indoor air handler on a wall or ceiling and connecting it to an outdoor compressor through a small conduit. Because this doesn't use ducts, it is often more efficient for targeted cooling. Factors affecting the price include the number of zones you need and the complexity of the refrigerant lines. Exact pricing confirmed free on the call.
