Whole house fan installation in Los Angeles
In the San Fernando Valley the afternoon is hot and the evening is not. A whole house fan is built for exactly that gap. When the outside air drops below the temperature inside, the fan pulls that cooler air in through your open windows, runs it through the house, and pushes the hot air out through the attic. In twenty minutes a house that was holding the day’s heat feels like the evening outside, and the air conditioner has not run once.
A.D.I. Electrical Services is a licensed C-10 electrical contractor, LIC# 977443, installing whole house fans across Los Angeles and the west Valley. We install QuietCool systems, which are the quiet, insulated kind rather than the loud single-fan units people remember from decades ago. Call (866) 561-7545 for a quote on your home.
How a whole house fan actually cools
It helps to be clear about what this is and is not. An air conditioner cools and recirculates the same air. A whole house fan does something different. It replaces the air. It draws the cooler outside air in and moves the hot inside air, and the heat that has soaked into your attic all day, up and out. The two are not rivals. Many Valley homes run the fan in the evening and overnight and barely touch the AC, then use the AC only in the peak of the afternoon. That is where the saving on the power bill comes from.
Why QuietCool and not the old kind
The whole house fans of the past were a single large fan bolted into a hallway ceiling, and they were loud enough that people stopped using them. QuietCool units sit in the attic and connect to the ceiling through an insulated duct, so the motor noise is separated from the room. They move a lot of air without the roar. The insulated, self-sealing damper also matters in winter, because a plain ceiling fan opening leaks your heated air straight into the attic when the fan is off. The QuietCool damper closes against that.
Sizing it to your house
A whole house fan only works well if it is sized to the house. Too small and it never quite clears the heat. Too large for the attic venting and it cannot exhaust properly and gets loud trying. Sizing is based on your square footage and ceiling height, and it depends on having enough attic exhaust venting for the air the fan is pushing out. This is the main reason we quote after seeing the home rather than over the phone. We check the attic, the venting and the ceiling space, then recommend the unit that matches, so you get the cooling without the noise.
Attic venting is part of the job
A whole house fan pushes a large volume of air into the attic, and that air has to get out. If the attic does not have enough exhaust venting, the fan is fighting a closed box and the system underperforms. Part of what we assess is whether your existing roof and gable venting is enough for the fan we are proposing. If it is not, we tell you what the attic needs, because installing a strong fan into a poorly vented attic is setting the system up to disappoint.
A clean, safe electrical install
This is an electrical installation as much as a cooling one. The fan needs its own properly wired circuit, a switch or timer control, and mounting that holds it securely and quietly in the attic. As a licensed contractor we wire it to code, fit the control you want, whether a simple switch, a timer or a remote, and make sure the ceiling opening and damper are sealed cleanly. Where a permit is required for the new circuit, we handle it and leave the work ready to pass inspection.
What it costs
The right unit and the right price depend on the size of your home, the fan model, and the state of your attic venting, so we give you a firm quote after a short visit rather than a number that changes later. The quote is free and there is no obligation. If it helps to plan the electrical side of your home together, we can look at the fan alongside anything else you are considering, such as panel capacity or added circuits, so it is all costed once. Call (866) 561-7545 and we will arrange a look.
Is a whole house fan right for your home?
It is a strong fit for most Valley homes, because the dry evenings here are what the system relies on. It works best when you can open windows in the evening and when the attic can be vented properly. It is less suited to homes that stay sealed, or where the evening does not cool down, which is rare here. We will tell you honestly if your home is not a good candidate rather than sell you a fan that will not deliver.

Frequently Asked Questions
The cost depends on your home’s size, the QuietCool model that fits it, and whether your attic has enough exhaust venting for the fan. Because those change the job, we give a firm quote after a short visit. The quote is free and there is no obligation. Call (866) 561-7545.
No, it works alongside it. An air conditioner cools and recirculates the same air. A whole house fan replaces hot inside air with cooler outside air in the evening and overnight. Many Valley homes run the fan when it cools down outside and use the AC only in the afternoon peak, which lowers the power bill.
Much quieter than the old single-fan units. QuietCool systems sit in the attic and connect through an insulated duct, so the motor noise is kept away from the room. They move a large volume of air without the roar people remember from older whole house fans.
It is sized to your square footage and ceiling height, and it depends on having enough attic venting to exhaust the air the fan moves. Too small and it never clears the heat, too large for the venting and it gets loud. We size it after checking your home and attic.
Sometimes. The fan pushes a large volume of air into the attic and that air has to get out. If the existing roof and gable venting is not enough, the system underperforms. We assess your venting as part of the quote and tell you if the attic needs more.
The new electrical circuit usually needs to be permitted and inspected. As a licensed C-10 contractor we handle the permit where the job requires one and leave the wiring ready to pass inspection.
