Giddens Brothers Plumbing, Heating and Air specializes in installation and service of whole house fans in Galt, CA and Surrounding Areas. Whole House Fans are an ideal money saving and comfort giving device for your home. A whole house fan expels hot air from your home into the attic while drawing in cool outdoor air through the windows, creating a comfortable and cool indoor environment. This type of fan offers natural and efficient cooling at a fraction of the cost of air conditioning, making it a top choice for enhancing home energy efficiency.
Understanding Daytime Heat Build-Up and Solutions
Throughout the day, rising outdoor temperatures result in heat being absorbed by the walls and interior of your home, making cooling challenging and expensive. As the outdoor temperature drops, the heat trapped inside your home can lead to discomfort, especially in upper levels. While air conditioning is a common solution, it can be costly during hot summer months. A Giddens Brothers or QA-Deluxe whole house fan offers a cost-effective solution by effectively reducing indoor temperatures, often eliminating the need for air conditioning and consuming significantly less energy than a standard central air system.
Considerations for Whole House Exhaust Fans
The unique ducted design of whole house fans overcomes many traditional challenges related to operation and installation. Issues like loud noise, heat loss, and maintenance problems are resolved. However, it's important to recognize that whole house fans have inherent limitations as cooling devices.
Distinction from Air Conditioners
While most air conditioners produce air around 20 degrees cooler than the indoor temperature, whole house fans use outdoor air to cool the house. With their high airflow rates, a 10-degree temperature difference between indoor and outdoor spaces is sufficient to initiate cooling.
Heat Dissipation from Entire Structure
During hot days, the building structure absorbs and retains heat, radiating it into the living space until it dissipates. Operating a whole house fan in the evening, night, or early morning not only eliminates stale indoor air but also cools the entire structure.
Differences in Cooling Old vs. New Homes
Older homes, with single-pane windows and less insulation, tend to heat up faster than newer homes with double-pane windows and better insulation. This allows outside heat to penetrate older homes more rapidly.
Managing Two-Story Homes
Heat tends to rise, resulting in warmer upstairs areas in two-story homes. To cool upstairs spaces effectively, keep downstairs windows closed and upstairs windows open. Adjust window openings based on room temperatures, as some rooms may require more ventilation than others.

Pull cooler evening air through the entire home.
Professional whole-house fan installation and service designed around the home’s size, layout, attic ventilation and the way your family wants to cool and refresh each room.
One fan creates a controlled path for air.
A whole-house fan does not manufacture cold air. It uses high airflow to draw cooler outdoor air through selected open windows, move it across the living space and exhaust warmer indoor air into the attic. Proper attic vents then release that heat outdoors. This can refresh stale indoor air and help cool the building materials that absorbed heat during the day.
Open selected windows
Outdoor air needs intentional entry points. The rooms with open windows receive the strongest cooling airflow.
Start the fan
A timer, wall control or compatible controller opens the insulated damper and runs the attic-mounted fan.
Move heat upstairs
Warm air is pulled from the living area through the ceiling grille and ducted into the attic space.
Exhaust through the attic
Soffit, gable, ridge or other approved attic vents allow the displaced air and heat to escape outdoors.
Good performance starts before installation.
Capacity alone does not determine success. We review the whole airflow path so the fan can move air effectively without excessive noise, pressure or wasted capacity.
Home size and layout
Square footage, ceiling heights, number of stories and room arrangement help determine appropriate airflow and grille placement.
Attic space and access
We check framing, insulation, electrical access and practical locations for the grille, insulated duct and suspended fan assembly.
Attic vent area
The attic must have enough net-free exhaust area for the fan’s airflow. Restricted venting reduces performance and can create pressure problems.
Sound expectations
Ducted designs isolate the motor from the ceiling grille. Placement, duct length, speed and mounting still influence sound.
Controls and speed
We discuss timers, multi-speed operation and how control placement affects daily convenience and energy use.
Climate and routines
Whole-house fans are most useful when evenings, nights or mornings are meaningfully cooler than the indoor air.
From airflow plan to finished grille.
We plan the installation to balance cooling reach, sound, service access and the existing attic structure. The goal is a clean ceiling appearance with the mechanical assembly isolated above.
Request installation guidanceThey solve heat in different ways.
Whole-house fan
- Uses cooler outdoor air rather than refrigeration
- Moves very large volumes of air through open windows
- Can flush stale indoor air and cool the home’s structure
- Works best when outdoor air is cooler and acceptable to bring inside
- Does not dehumidify, filter or guarantee a set indoor temperature
Air conditioning
- Actively removes indoor heat using refrigeration
- Operates with windows and doors closed
- Can cool even when outdoor air is hotter than indoor air
- Provides controlled temperature and may remove humidity
- Typically uses more electricity than a whole-house fan
Direct the airflow where you want it.
Evening and early morning
Wait until outdoor air is cooler than the indoor space. Open appropriate windows before starting the fan, then close the home again as outdoor temperatures rise.
Two-story homes
Because upper floors collect heat, opening upstairs windows while limiting downstairs openings can concentrate more airflow where it is needed.
Room-by-room balance
Open windows wider in warmer rooms and reduce openings in rooms that cool too quickly. Never run the fan with every window closed.
Daytime heat buildup
Walls, floors and furnishings store daytime heat. A longer night flush can cool both the air and the structure, delaying next-day heat buildup.
Old and new homes
Older homes may gain heat faster through insulation and window differences. Newer homes may hold heat longer, making controlled night ventilation useful.
Outdoor air quality
Keep the fan off when smoke, dust, pollen, odors or outdoor humidity make outside air undesirable.
Keep airflow quiet and dependable.
Whole-house fans are relatively simple, but controls, dampers, mounting, duct connections and attic ventilation still need to work together.
Noise or vibration
We inspect fan mounting, duct contact, loose components, speed operation and grille or damper movement.
Weak airflow
Possible causes include closed windows, restricted attic vents, duct problems, a stuck damper or a fan that is not correctly sized.
Control problems
Timers, wall switches, speed controls and electrical connections can be checked when the fan will not start or changes speed unexpectedly.
Cooler evening air is already outside.
