Exhaust Fan Installation
Exhaust fan installation includes fan mounting, electrical connection, ductwork, and exterior venting—removing moisture and fumes before they cause damage.
What This Service Includes
Many fans vent into the attic instead of outside—causing rot, mold, and ice damming. Peeling paint, mold spots, and persistent humidity indicate inadequate ventilation.
D & D Electric provides complete installation: proper fan sizing, ductwork to exterior, and verified airflow. No moisture deposited in attics.

| Extremely hot upstairs in summer | Poor attic ventilation | Higher AC costs, roof damage |
Our Process
- 1
Assessment and Sizing
Measure space, calculate CFM needed. 50 sq ft bathroom = 50 CFM minimum.
- 2
Duct Routing Planning
Shortest run, fewest bends—to wall cap or roof vent, never into attic.
- 3
Installation
Ceiling opening, fan mount, electrical wiring, ductwork, exterior vent cap.
- 4
Testing and Demonstration
Confirm airflow at exterior vent—not just motor running.
Benefits of Professional Service
Moisture Damage Prevention
Remove moisture before it causes rot, deterioration, and mold. Fan installation costs less than repairing damage.
Improved Air Quality
Remove moisture, odors, smoke, and cooking fumes at the source. Better health for allergy/asthma sufferers.
Energy Savings From Attic Ventilation
Attic fans reduce cooling costs by removing trapped heat. 150-300 watts saves far more in AC demand.

"D&D Electric has become our go-to electrician service. We first worked with them a few years back when we had an issue and other contractors couldn't schedule us and D&D by contrast came out the next day and did quality work for a reasonable price and were friendly and personable throughout."
