Whole House Fans

Can whole house fans be used as an alternative to air conditioning?


Yes! Whole house fans cool your entire home and maintain comfortable temperatures more efficiently than A/C, and for a fraction of the cost! Whole house fans not only cool your home better than central air conditioning, they also replace the stale, stagnant indoor air with fresh air from outside. Without additional ventilation, air conditioners only recirculate indoor air, which can spread viruses and other contaminants throughout your home.




Can I use a whole house fan with my air conditioner?


Absolutely! As a matter of fact, a whole house fan can make your existing air conditioning system even more efficient by cutting A/C related energy costs by up to 90%. As superheated air accumulates inside the attic throughout the day, those relying on A/C alone find upper levels of their home remain a lot warmer than the lower levels. To combat this, the A/C unit will run continuously — at a $1 per hour! — causing excessive strain on the system. A whole house fan is designed to remove superheated air from the attic in a matter of minutes, reducing the strain and reliance on your A/C unit while delaying or eliminating the need to run your air conditioner throughout the day.




How do whole house fans work?


Whole house fans rely on a source of fresh air to efficiently cool and clean the air inside your home. When the temperature outside is cooler than it is inside, simply open a few windows or doors 4-6 inches, turn on the whole house fan, and enjoy the cool, comfortable breeze moving throughout your home. When the temperature outside begins to rise, close the windows and doors and draw the blinds to maintain a comfortable indoor temperature during the hottest times of the day.




What is the best whole house fan?


The best whole house fan for your home depends on the size of your home and the amount of airflow needed. We offer whole house fans from two industry-leading manufactuers — traditional whole house fans from Triangle Engineering, and ducted whole house fans by QuietCool. Traditional whole house fans provide the most airflow and are installed against the ceiling, on top of the celiing joists. QuietCool house fans are the most energy efficient whole house fans and are suspended from the roof framing in the attic for additional noise reduction.




How much noise do whole house fans make?


When your whole house fan is in use, you may hear a sound similar to other HVAC systems. QuietCool whole house fans are the quietest house fans available, with ultra-quiet motors and suspended installation for added noise dampening. Traditional whole house fans will make more noise, though, our installers specifically engineer the framework of the fan so that the finished product is as secure and as quiet as possible.




How much do whole house fans cost?


The cost of a whole house fan system depends on the size of your home, the amount of ventilation you need, and the difficulty of the installation. In general, whole house fan installation is a fraction of the cost of air conditioning and other home cooling systems. House fans operate for pennies an hour, require little to no maintenance, and can deliver a return on your investment in as little as one day!





Attic Ventilation

How much attic ventilation do I need in my house?


A typical home has two square feet of total net free attic ventilation in place, but each home is different. Additonal attic fans may be required in order to make an existing air conditioning system operate more efficiently, or for a whole house fan to effectively cool your entire home.




How do I improve attic ventilation?


In order to improve attic ventilation, roof vents and attic fans are installed to create the total amount of net free ventilation that is required for your home cooling system to operate as efficiently as possible. Attic fans and vents come in a variety in makes and models, including powered, passive, and solar-powered options to suit most any home.




What is the difference between attic fans and whole house fans?


Attic fans are smaller fans mounted on the roof or inside the gable of your attic. Attic fans are controlled by a thermostat switch and help to flush out the hot air trapped in the attic but do not pull air through the living area of the home. Attic fans are ideal for homes with existing cooling sytems, making them run more efficiently, or for homes that stay naturally cool throughout the year. Whole house fans are installed in the ceiling of the home and pull air through the entire home.




Is attic ventilation really important?


Yes! Attic ventilaiton is essential to any home ventilation system, whether a whole house fan, traditional air conditioning, or evaporative cooling system. Attic fans and vents also protect your home from excess moisture buildup and ice damming during the winter, which can cause mold and dramatically shorten the lifespan of your roof.




Do attic fans work?


Yes! Attic fans and whole house fans are proven to cool your home more efficiently and expel superheated air and moisture buildup from your attic. Without sufficient attic ventilation, hot, humid air gets trapped inside your attic and can cause mold, ice damming, and significantly impact the structure of your roof.

Sun Tunnels

What are Sun Tunnels?


Sun Tunnels (also known as solar tubes, sun pipes, sun tubes, or tubular skylights) are a smaller, cheaper, and easier-to-install alternative to traditional skylights. With a high-impact dome located on the roof, the highly reflective interior funnels natural daylight into the poorly lit areas of your home.




How much do Sun Tunnels cost?


The cost of a sun tunnel system for you howm will depend on the number of tunnels installed and the difficulty of the installation. In general, Sun Tunnel installations are a fraction of the cost of traditional skylights and require little to no maintenance. Contact us today for a no-hassle free quote!




How do Sun Tunnels work?


Sun Tunnels draw natural daylight into your home through sealed openings in your roof, much like traditional skylights. Sun tunnels are designed to brighten poorly lit areas of your home where traditional skylight installation isn't possible, like closets, laundry rooms hallways, and more.




Do Sun Tunnels really make a difference?


Absolutely! Sun Tunnels are a proven way to fill dark areas of your home with all natural daylight. The beauty of natural daylight can transform kitchens, bathrooms, home offices and other areas in your home without the need for artificial lighting, and help curb your energy costs as well!
