This is a typical range, not a quote. The sections below explain what moves the price for this job. The dot marks the middle price, and a + means some businesses charge more.
What the job involves
An AC unit installation puts in the cooling equipment: an outdoor unit that sends heat out of the house and usually an indoor coil that cools the air, joined by new or reused refrigerant lines. Your furnace or air handler and most of your ducts stay where they are, which is the main difference from a full system replacement.
The outdoor unit and the coil indoors are designed as a pair, so a quote that replaces only one of them deserves a question. Some new outdoor units use a newer refrigerant that an old coil was not built for, and the maker may require a matching coil.
Some quotes are for adding central air to a house that has a furnace and ducts but no air conditioner yet. That needs everything above, plus a place to set the outdoor unit and power run to it.
What's usually included
- Setting the new outdoor unit in place
- Connecting it to the indoor coil, the refrigerant lines and the power
- Running the new unit to confirm that it cools
What moves the price
- Single speed or variable speed
- Some air conditioners run at one speed, and others adjust to how hot the day is. The ones that adjust usually cost more to buy.
- New coil or old coil
- Installing a new coil with the new outdoor unit costs more than connecting to the coil you have. Ask which one the quote assumes, and whether the maker's warranty allows the old coil.
- Where the outdoor unit goes
- Setting it on a pad in the old spot is the simplest case. Moving it can mean new refrigerant line and new wiring to reach the new spot.
- Electrical work
- A new unit can need a different breaker or heavier wire than the one it replaces, and some quotes leave that work to an electrician.
- First-time central air
- Adding cooling to a house that only had heat also means a drain for the new coil, and some companies check that the furnace fan and ducts can move enough air for cooling. That check, and any changes it calls for, add to the price.
Getting a quote
Questions to ask each HVAC company before you compare prices:
- Does this price include a new indoor coil, or only the outdoor unit?
- Are the outdoor unit and the coil a matched pair, and what are the model numbers?
- Will you reuse my refrigerant lines or run new ones?
- What happens to the old outdoor unit and its refrigerant?
- Does the equipment warranty need to be registered, and will you do that?
- Who pulls the permit if my city or county requires one, and is it in this price?
