Attic Fan Installation
Attic Fan Installation
An attic fan exhausts superheated air out of the attic itself, which is a different job from a whole house fan that moves air through your living space. A San Diego attic can sit far hotter than the outside air on a summer afternoon, and that heat radiates down through the ceiling for hours after sunset. That is why upstairs rooms stay warm long after it has cooled off outside. We measure the attic before anything is quoted, find where the heat pools, and check the soffit and eave intake, because a fan with nowhere to pull from just fights itself. Eddie comes out, looks at the attic ventilation you already have, and gives you a straight number before any work starts. What you get is a cooler ceiling, less standing load on the air conditioning, and an attic that is not baking your insulation and whatever is stored up there.

Frequently Asked Questions
What is the difference between an attic fan and a whole house fan?
An attic fan exhausts hot air out of the attic itself. A whole house fan moves air through your living space. They solve different problems, and plenty of San Diego homes benefit from both. If someone quotes you one without asking which problem you have, get another opinion.
Why are my upstairs rooms still hot after the sun goes down?
Because your attic is still hot. A San Diego attic can sit far above outside air temperature on a summer afternoon, and that heat radiates down through the ceiling for hours after sunset. Venting it is what stops the ceiling acting like a radiator all evening.
Do I need more intake venting as well as the fan?
Usually, and it is the step that gets skipped. Exhaust without intake does very little, because the fan cannot pull air it has no path to. We audit soffit and eave intake area before we cut anything, and sometimes intake is the real fix.
Will an attic fan lower my energy bill?
It reduces standing load on the air conditioning by lowering the ceiling temperature the system is fighting. We are not going to put a percentage on it, because it depends on your insulation, your roof and how you run the house. The comfort difference upstairs is the part people notice first.
Does an attic fan help with anything besides heat?
It helps the attic dry out, which matters for insulation performance and for anything you store up there. Damp compressed insulation stops doing its job, and that shows up on the bill long before it shows up as a visible problem.
