How does a whole house fan differ from an attic fan?

An attic fan only clears hot air from the attic space to protect the roof. A whole house fan pulls air from the living areas and exhausts it through the attic to cool the occupants.

When is the best time to run a whole house fan in Atlanta?

These fans are most effective in the evening or early morning when the outdoor temperature is lower than the indoor temperature.

Do I need extra attic vents?

Most homes require additional venting to handle the high volume of air. Our technicians calculate the required vent area to ensure hot air escapes without restriction.

Can a whole house fan replace my air conditioner?

It cannot dehumidify air, but it significantly reduces the hours your air conditioner needs to run. In Metro Atlanta, it is best used as a supplement during milder hours.

Atlanta summers bring persistent heat that forces air conditioning systems to run around the clock. A whole house fan offers a powerful alternative for cooling your home during the evening and early morning hours when outside temperatures drop.

By pulling cool outdoor air through open windows and exhausting hot, trapped air out through the attic vents, these systems create a refreshing breeze and lower the temperature of your living space quickly. R.S. Andrews helps homeowners across Metro Atlanta integrate these systems into their existing ventilation strategies to improve comfort and decrease monthly utility bills.

The Mechanical Benefits of High-Volume Ventilation

Whole house fans cool the physical thermal mass of your Atlanta home. While traditional AC focuses on the air, these high-volume systems pull heat out of your drywall, framing, and flooring.

Energy-Efficient Cooling & Thermal Control

Lower energy consumption reduces your reliance on central AC by using high-efficiency motors that draw minimal wattage compared to a compressor. This allows you to maintain comfort during Atlanta’s humid shoulder seasons at a fraction of the cost of a full HVAC cycle.

Rapid Home Air Exchange & Odor Removal

Improved ventilation removes stale air, humidity, and stubborn odors in minutes by replacing the home’s entire air volume multiple times per hour. This constant flow creates a natural breeze that lowers the perceived temperature by 5 to 10 degrees.

Extended HVAC System Longevity

Reduced mechanical workload occurs by lowering the total cooling cycles required during peak afternoon hours. Pre-cooling your home’s structural mass at night allows your primary air conditioner to work significantly less the following day, preventing premature wear.

Quiet, High-Volume Performance

Acoustic comfort is achieved through modern insulated ducting and high-torque brushless motors that eliminate the vibration common in older models. These components move massive air volumes while remaining whisper-quiet in the living areas below.

Whole House Fan Installation & Sizing

The effectiveness of a whole house fan depends entirely on attic capacity. If your attic lacks sufficient net free venting area, the fan creates backpressure. This reduces efficiency and can blow dust back into the living space.

R.S. Andrews technicians evaluate your attic square footage and existing soffit or ridge vents to ensure the air has a clear path to exit the home. We calculate the specific cubic feet per minute requirements based on the total volume of your house to select the right fan size for your needs.

Technical Installation Steps

Precision Cutting: We create a precise opening in the ceiling of a central hallway.
Structural Mounting: The fan housing is securely mounted to the ceiling joists.
Electrical Integration: We handle all wiring and the installation of timers or variable speed switches.
Thermal Sealing: We install R-value insulated doors to prevent heat loss during winter months.

Whole House Fan Repair & Maintenance

Maintenance for these systems is essential for long-term performance. Our team inspects the shutters for a proper seal and cleans the fan blades to maintain balance.

If your existing fan makes grinding noises or fails to pull air effectively, our technicians provide rapid repairs to restore your home’s airflow. We check motor capacitors and belt tension on older models to prevent unexpected mechanical failure during the peak of the cooling season.

Schedule today! We’re ready to deliver expert service and a smile to your door.

Preventative maintenance service I am a new customer looking for quality service that is honest and the contractor that has integrity so far that is what I feel they have presented. Time tells all jury is still out. My window of time was 2 to 6 and the tech showed up at 7:30. That’s why my jury is still out. I understand that things happen but the poor tech didn’t leave until almost 9 PM three hours passed the window.

After 16 years with a big company, I decided to try RS Andrews and elated I did so. Devonte was the technician and did Yeoman's work. He was knowledgeable, professional, and to be honest, passionate about his work...Mastercraft. No exaggeration. He kept me informed about the status of my units, and it was refreshing he came to work, and not to try to hard sell me.

I understand things break and need to be replaced, but there is a limit, and appreciate I didn't get the doom and gloom regarding my system. I gleefully signed up for the yearly agreement.

I take no joy cutting relations with the previous company I had. I was actually one of their first customers. I severed ties not for me, but for those who are still with them. I told them they have disappointed me for my loyalty and went after the quick buck.

Loyalty appreciation, and not the quick buck is what's important in the long run. At least to me.

Happy to be on board with RS Andrews, and thank you Devante.
