    Whole House Fans in Seattle

    Whole house fan systems are most beneficial in homes without central air systems or in households that have structural issues that make a central air system ineffective.

    Especially in places like Seattle — where summers are mild, and more than 65% of homes do not have central air — whole house fan systems are an excellent choice for temperature control and ventilation.

    Even if your home has central air, a whole house fan can help you save on the high energy costs of central air operation.


    Benefits of a Whole House Fan

    Cools Off Home Quickly 

    Central air conditioners, especially in older homes, require a certain amount of coolant to operate, and it takes a considerable amount of time for them to generate cooler air. Whole house fans don’t require coolant and get to work cooling off your home immediately.

    Uses Less Energy than Traditional Central Air

    A whole house fan uses 25% less energy than an air conditioner does. This makes it a more environmentally sound choice, as well as one that can cut down your energy bill.

    Makes Indoor Air Healthier

    A whole house fan system keeps indoor air from becoming stagnant. When air is stagnant, it is likely to amass and spread noxious or unpleasant odors. A whole house fan system keeps air circulating throughout the home, making it healthier to live in.

    Lasts Longer

    With fewer moving parts and less wear-and-tear, a whole house fan system’s life expectancy is much longer than central air.

    Requires Less Maintenance

    Especially in milder climates like Seattle, whole house fans demand much less maintenance than more complex central air systems. An annual cleaning and occasional dusting are usually enough to keep a whole house fan in good operating condition.

    Works More Quietly

    A whole house fan works without the often intrusive noise that tends to come with a central air unit — your house will be cooler and quieter as a result.

    Where is a Whole House Fan Good For?

    Whole house fans are generally best for areas where it’s not oppressively hot most of the year. Seattle, of course, fits that description. Since a whole house fan needs open vents, you should also be comfortable having your windows open when it’s in operation.

    There are a few space considerations to keep in mind. A whole house fan is best suited in homes with at least one square foot of net-free area for every 750 CFM (cubic feet/minute) of fan airflow.

    Whole House Fan vs. Attic Fan

    Obviously, the biggest difference between a whole house fan and an attic fan is what they cover. Whole house fans cool your entire living area. Attic fans are used only to control and ventilate the air in attics or crawl spaces. While attic fans can help support overall house temperature, they aren’t designed to work in other rooms of the home, but whole house fans are.

    We live in an older home near a large park area. Since buying our home, we’ve had to deal with the occasional rat. These guys came out and sealed my entire attic space – vs setting a few traps. Then vacuumed out the entire space that had nearly 100 years of debris – including from our new roof and insulated the entire house. Love the 5 year warranty against the rats and we already notice how much warmer the house is. The did a great job keeping area clean and protecting floors, walls while working. Highly recommend.


    It’s a stressful situation when you find black mold in your home. The guys at Attic Projects were professional, polite and respectfully clean. They finished the job in a timely manner and went the extra mile to make sure I was satisfied with their work. Once the job was completed we instantly noticed a difference in our home’s humidity- going from 70% to the optimal 50%. I’d highly recommend these guys. Jordan, your customer service was top notch, thank you for making this a stress free experience.


    Attic Projects was so incredibly thorough and detailed with their description of how and why they were going to do each step, I knew I could trust them. These guys get it!! Total professionals, hard workers and they invited me to poke my head up in the attic during and after the job was complete. My in-laws received before and after pics and received a 5-year warranty on rodent proofing This was a big job and these guys absolutely killed it. I’d recommend them to anyone with similar issues. Thanks Attic Projects!!

    Frequently Asked Questions:

    Why do I need a whole house fan if my HVAC is working normally?

    A whole house fan can assist your HVAC so that air is evenly flowing throughout your home, and so that the HVAC doesn’t work as hard to keep a consistent temperature in your home.

    Do I need a whole house fan in Seattle?

    Although the winters are colder in Seattle than our neighboring west coast states, the summers can get muggy and warm, making all energy bills skyrocket. Keep your summer utility bills down with a whole house fan to keep your home cooler for less.

    Can I have a whole house fan if I have an attic fan?

    A whole house fan requires windows and doors to circulate air throughout your home. Attic fans require vents to suck cool air up from your home into your attic to cool down your attic. The main functions of each fan perform different outcomes.

    Humane Rodent Removal and Proofing

    Rodents are a nightmare for any homeowner. They can lower the value of your home by causing serious damage, foul odors, and extensively unsanitary conditions. They also pose a significant health risk to you and your family by spreading disease and causing illness. The last thing you want is to waste your time removing rodents, only to have them move right back in. At Attic Projects, we not only humanely remove the rodents and pests from your home, but we also rodent-proof your home so they can’t come back. In order to keep the pests and rodents out permanently, you have to close up every entry point that they may squeeze into. Call Attic Projects today to get your free estimate.
