Installing a central air conditioner without existing ductwork can be an extensive project. Before you call the HVAC contractor, as always, it’s a good idea to know how much it costs. We’ve researched to help you get the answer and here’s our finding.
The cost of central air installation ranges anywhere between $5,000 to $12,000, with most homeowners paying a little over $7,000 for a 16 SEER unit with new ductwork.
Below, we break down the major factors that determine the central air installation price, as well as the other important considerations to make when getting a central air conditioner.
Do You Really Need Ductwork To Install Central Air Conditioner?
Unlike a typical air conditioner that relies on an evaporator to blow cold air, the central air conditioner supplies and distributes air using ductwork. Therefore, the latter simply is necessary for it to operate.
The Cost Of Installing a Central Air Conditioner
Typically, the installation costs $4,800 for smaller units and $7,000 for larger systems. The price goes down with existing ductwork. The factors below can also influence the price tag:
- Home Size: A properly sized central air conditioner provides a greater ability to cool your space. The bigger your house, the bigger the air conditioner you need- the higher the price.
- Ductwork Location: Depending on the ductwork location (basement, within walls, or attic) extra tools and accessories might be utilized- that can drive the cost as well.
- System Type: Other system types are equipped with extra features and accessories which come at a price.
- Temperature Control Zones: This feature allows homeowners to control the temperature in different rooms; it has an added charge.
- Number of Vents: The more vents your house needs, the more ducts it requires, which can increase the installation fee.
- Duct Materials: The material used for the ductwork (sheet metal, fiberboard, and wire coal) can affect the number.
