What drives the price
- Number of zonesEach indoor head adds equipment, line set and labor. Multi-zone outdoor units cost more than single-zone ones.
- Line set lengthLonger runs between the indoor and outdoor units add refrigerant line and labor.
- EfficiencyHigh-efficiency and hyper-heat models cost more but perform better in cold climates.
- ElectricalMost systems need a dedicated 240-volt circuit.
How this estimate works
The calculator multiplies your indoor zones by the installed price range for the option you pick, then adds any extras you tick and typical outdoor unit pad and mounting. The headline number is the midpoint of your range. Low-end prices fit simple jobs in lower-cost areas. High-end prices fit complex jobs, premium brands and high-cost metros.
Get at least three written quotes before you hire. Ask each contractor to list materials, labor, permits and disposal separately so you can compare them line by line. Read how we build our ranges.
