Attic fan installation cost by type
| Fan type | Installed price | Good to know |
|---|---|---|
| Passive vent or roof turbine | $75–$300 | No power; the lowest-priced option |
| Electric fan | $100–$1,000 | Needs wiring; HomeGuide prices it highest |
| Solar fan | $300–$1,200 | No wiring to the house, but a pricier unit |
| Dual-power fan (electric and solar) | $300–$1,000 | Uses both solar and house power |
These are installed prices per fan, covering the unit and the labor, with the labor share adjusted for your state. A thermostat, a humidistat and electrician time for wiring are separate lines in the calculator, because many fans include a thermostat and only powered fans need wiring.
What changes the price
Power source is the main factor: passive vents cost least, and electric and solar fans cost more because of the unit and the wiring or panel. Mounting also matters. A roof-mounted fan needs a hole cut in the roof, and a gable fan needs a hole in the wall, and the guides we read do not agree on whether the cutting is in the installed price, so ask. Whole-house fans are a different, larger product and are not priced here.
Extra costs to expect
| Item | Typical cost | When it applies |
|---|---|---|
| Thermostat | $100–$400 | If the fan does not include one |
| Humidistat | $50–$100 | Optional, for moisture control |
| Electrician for wiring | $65–$130 | About an hour for a simple hookup; a new circuit costs more |
Check that the attic has enough vent area to supply the fan, since a fan with too little intake air can pull conditioned air from the house. Ask the installer about this before you buy.
Questions to ask before you hire
- Is the price for the fan, the roof or wall cutting and the wiring together?
- Does the fan include a thermostat?
- Is the attic vent area big enough for the fan?
- Who does the electrical work, and is it permitted where you live?
- What is the warranty on the unit and on the roof penetration?
