Calculate your estimated costs
This is an estimate based on average 2026 prices. Actual costs may vary. Always request multiple quotes for an exact price.
Cost factors
The total cost usually consists of:
- Indoor and outdoor unit: 45-60% of the total
- Installation and refrigerant piping: 25-35% of the total
- Electrical connection and wiring: 10-15% of the total
- Wall penetrations, brackets, and finishing: 5-10% of the total
These percentages can vary depending on the chosen system, power, and length of the piping.
Why do prices vary?
- Single-split vs. multi-split: A single-split cools or heats one room and is cheaper. A multi-split with multiple indoor units on one outdoor unit is more expensive but more efficient for multiple rooms.
- Capacity and room size: The required power (expressed in kW or BTU) depends on the size and insulation of the room. An incorrectly sized system is inefficient.
- Brand and ENERGY STAR rating: Brands like Daikin and Mitsubishi Electric are more expensive to purchase but have higher COP values and last longer than cheaper alternatives.
- Pipe length and wall penetrations: The more meters of piping to be laid and the more walls to be drilled through, the higher the installation costs.
Subsidies & incentives
While standard AC units don't qualify for federal tax credits, energy-efficient heat pump systems that provide both heating and cooling do.Consider a heat pump insteadTax credit: up to $2,000 via IRA Section 25C for qualifying heat pump systemsDual benefit: heat pumps provide both cooling and heating, potentially replacing both AC and furnaceEfficiency: modern heat pumps are 2-3x more efficient than traditional AC + furnace combinationsIf you're installing AC in a home without an existing system, a heat pump may be the better investment — you get cooling, heating, and a $2,000 tax credit.
