Q.   How do attic fans operate?

A.   Attic fans exhaust air from your attic (outside), while pulling fresh air in through available intake vents.                        

Q.   Do I need a humidistat?

A.  You need a humidistat if you live in a moist, humid climate.  A humidistat will activate your attic fan when moisture build up is detected.
This will prevent moisture from condensing an causing mildew and mold growth or damage to your home structure.

Q.   Where on my roof is a roof mounted attic fan installed?

A.   Installations vary slightly, depending upon specific roof and attic configurations.  Typically, we install roof mounted attic fans to the rear of the home, approximately 18 inches below the roof peak.                                                                                                                                                   ^ Top


Q.   How much electricity does a power attic ventilator use?

A.   A 1170 CFM Attic Fan will use no more than 1 amp/110 watts.  A 1500 CFM Attic Fan will use no more than 3 amps/325 watts.

Q.  Will an attic fan pull air from my living spaces?

A.  No, unless you have un-sealed holes and air leaks.  Attic fans pull replacement air in through available intake vents.

Q.  How do you prevent roof leaks when you install a roof mounted attic fan? 

A.   First we use precise cutting techniques and maximize the fit of the attic fan insert.  Secondly, we are one of the very few contractors using
an underlay process, followed by a twenty year weatherproof sealant.

Q.   Will an attic fan look ugly on my roof?

A.   Airvent Roof Mounted Power Attic Ventilators are very low profile and will not compromise the aesthetics of your roof.

Q.   What is a whole house fan?

A.    A whole house fan is a very powerful fan that can exchange large volumes of air in your living spaces.  Typically installed flush with the ceiling
of a central hallway adjacent to your attic.  Whole house fans have automatic louvers that open when the fan is turned on and automatically close when the fan is off.  When the fan is on, the louvers open and the fan pulls air into your living (from open windows and doors) replacing existing air that is pulled up into your attic and pushed out through attic exhaust vents.                                                                                                                                                                              ^ Top


Q.   If I add an attic fan, will I also need to add intake vents?

A.   In order to properly ventilate your attic space, you must have the recommend intake venting.  If your attic fan cannot work effectively without replacement air.

Q.   Do I need intake vents for a whole house fan to work properly?

A.   Yes, whole house fans pull large volumes of air up into your attic space, very quickly.  If you do not have static vents (vents that will allow air to enter or exit), your whole house fan will perform poorly.                                                                                                                            ^ Top


Q.   Sometimes my whole house fans does not seem to work well any ideas?

A.   Be sure that you do not have too many doors or windows open while running your fan.  It is recommend that you focus on specific living areas.  For example, you may want to cool your kitchen and family room areas near dinner time.  Open windows in those rooms ONLY, then turn on your fan.   Later, you may want to cool bedrooms.  Open bedroom windows ONLY, then turn on your fan.  This allows the power of your whole house fan to be focused and the target rooms will cool much quicker.

Q.   Can I install a power attic ventilator and a whole house fan?

A.  Yes, in fact it is recommend that you exhaust your attic to prevent heat build-up when you are not using your whole house fan.  The combination furthers energy cost savings as well as increased comfort in your living spaces.                                                                                        ^ Top


Q.   Will installing an attic ventilator effect my attic insulation?

A.   No, in fact many insulation manufacturer warranties require proper ventilation.                                                 ^ Top

A.    Yes.  Even with very expensive room air filters, attic mold and mildew can enter your living space and effect air quality.
