What to Expect from Our Bathroom Exhaust Fan Installation Service
Proper bathroom ventilation is essential for protecting your home from moisture damage, mold growth, and deteriorating finishes. A quality exhaust fan removes humid air generated by showers and baths, preventing the moisture problems that lead to peeling paint, warped trim, mold behind walls, and even structural rot in severe cases. AJ Long Electric installs premium bathroom exhaust fans throughout Northern Virginia homes in Fairfax County, Loudoun County, Prince William County, and Arlington. We specialize in ultra-quiet fans rated at 1.0 sone or less -- so quiet you can barely hear them running -- from top brands including Panasonic WhisperCeiling, Broan-NuTone, and Delta BreezSlim. Our electricians handle complete installations including fan unit mounting, dedicated circuit wiring, ductwork routing to the exterior, and proper roof or soffit vent termination. We also replace existing noisy or underperforming fans with modern, efficient units and install combination fan-light-heater units for added functionality. Every installation includes proper CFM sizing based on your bathroom's square footage per ASHRAE standards, ensuring adequate air exchange. We verify that exhaust ducting terminates outside your home -- never into an attic or soffit -- to prevent moisture from accumulating in unintended areas. In Great Falls, we have seen how 400-600 amp services for large estates affects homeowners. That is why we take the time to assess your entire electrical system and recommend solutions that address both immediate needs and long-term reliability. Every bathroom exhaust fan installation project we complete in Fairfax County includes a thorough inspection, detailed documentation, and our commitment to your complete satisfaction.

Bathroom Exhaust Fan Installation Questions from Great Falls Homeowners
What size exhaust fan do I need for my bathroom?
The general rule is 1 CFM per square foot of bathroom area, with a minimum of 50 CFM. A standard 5x8 bathroom needs at least 50 CFM, while a large master bath may need 100-150 CFM. For bathrooms with jetted tubs or steam showers, we size up further. We calculate the exact requirement during our assessment.
How loud are modern bathroom exhaust fans?
Modern fans are dramatically quieter than older units. Fan noise is measured in sones -- the best modern fans operate at 0.3-1.0 sones, which is barely perceptible. By comparison, older fans typically operate at 3-4 sones. Panasonic WhisperCeiling fans at 0.3 sones are our most popular ultra-quiet choice.
How much does bathroom exhaust fan installation cost in Northern Virginia?
Bathroom exhaust fan installation typically costs $250-$600 in the DC metro area for a standard replacement. New installations requiring ductwork routing and exterior venting run $400-$900. Combination fan-light-heater units cost more due to additional wiring. We provide exact pricing after assessing your bathroom.
Should my exhaust fan vent into the attic?
Absolutely not. Exhaust fans must vent to the exterior of your home through a roof cap, soffit vent, or wall vent. Venting into an attic deposits warm, moist air that causes mold growth, wood rot, and insulation damage. If your current fan vents into the attic, we correct this during replacement.
Can I install a fan with a built-in light and heater?
Yes, combination fan-light-heater units are very popular in Northern Virginia bathrooms. They provide ventilation, overhead lighting, and supplemental heat from a single ceiling unit. These require a dedicated circuit and multi-function wall switch. We install all major combination units from Broan-NuTone and Panasonic.

Bathroom Exhaust Fan Installation in Great Falls Case Studies
See how we have helped homeowners across Northern Virginia with their bathroom exhaust fan installation in great falls needs.
Master Bathroom Mold Remediation and Ventilation Upgrade
colonialChallenge
A homeowner discovered black mold behind the bathroom ceiling paint and along the shower grout. An investigation revealed the original 1994 exhaust fan was venting directly into the attic, depositing warm, moist air onto the attic insulation and roof decking. The existing fan was also underpowered at only 50 CFM for a large master bathroom.
Solution
AJ Long Electric removed the old fan and installed a Panasonic WhisperCeiling 150 CFM unit sized for the 120-square-foot master bath. We routed new 6-inch insulated ductwork through the attic to a new roof cap vent, eliminating the attic moisture dump. A humidity-sensing wall switch was installed for automatic fan activation.
Result
The bathroom clears steam in under 5 minutes after a hot shower, the attic moisture issue is completely resolved, and the fan operates at 0.3 sones -- so quiet the homeowner initially thought it was not running. The mold remediation company confirmed the ventilation fix addressed the root cause.
Three-Bathroom Exhaust Fan Replacement Package
townhomeChallenge
All three bathrooms in a 2003 townhome had original builder-grade exhaust fans that were loud, ineffective, and one had stopped working entirely. The second-floor hall bathroom had visible mildew on the ceiling, and the ground-floor powder room had no fan at all despite having no window. None of the existing fans had been cleaned in years.
Solution
We replaced both second-floor exhaust fans with Broan-NuTone ultra-quiet 80 CFM models using existing ductwork after cleaning and inspecting the ducts. For the powder room, we installed a new Panasonic WhisperFit 80 CFM fan with a new duct run to an exterior wall vent. Each bathroom received a timer switch allowing 20, 40, or 60-minute run times.
Result
All three bathrooms now have effective, quiet ventilation. The mildew issue in the hall bathroom stopped within weeks of the installation, and the powder room has its first-ever exhaust fan. The total project was completed in a single day.
Luxury Spa Bathroom with Dual Ventilation Zones
estateChallenge
A high-end master bathroom renovation featured a 200-square-foot space with a freestanding soaking tub, oversized steam shower, and separate water closet. The architect specified independent ventilation zones to handle the extreme steam production from the walk-in steam shower without over-ventilating the rest of the bathroom.
Solution
We installed two exhaust fans: a Panasonic WhisperCeiling 200 CFM unit directly above the steam shower with a dedicated humidity sensor, and a separate 80 CFM unit in the water closet area. The steam shower fan was connected to an inline duct booster to handle the 12-foot duct run to the roof cap. Both fans operate independently with separate controls.
Result
Even during extended steam shower sessions, the bathroom remains comfortable and clear outside the shower area. The dual-zone approach prevents over-extraction of heated air from the main bathroom while aggressively venting the steam shower enclosure. The project passed Arlington County inspection with no corrections.
Combination Fan-Light-Heater for Bathroom Renovation
split-levelChallenge
During a bathroom renovation in a 1968 split-level, the homeowner wanted to replace a bare ceiling light fixture with a combination unit that provided ventilation, lighting, and supplemental heat for the cold winter mornings typical in their poorly insulated bathroom. The existing wiring was a single switch leg with no dedicated circuit.
Solution
AJ Long Electric installed a Broan-NuTone combination fan-light-heater unit with a 1500-watt heating element, 100 CFM fan, and integrated LED light. We ran a new dedicated 20-amp circuit from the panel to support the heater element and installed a four-function wall switch for independent control of fan, light, heat, and night light.
Result
The homeowner gained three functions from a single ceiling unit, and the dedicated circuit ensures the heater runs without tripping breakers. Morning bathroom temperatures are noticeably warmer, and the integrated LED eliminated the need for a separate light fixture.

Bathroom Exhaust Fan Installation in Great Falls by Housing Type
Different home styles have unique electrical characteristics. Select your housing type to see specific considerations.
Colonial Homes
Common Issues
Special Considerations
Colonial homes offer good attic access above second-floor bathrooms, making ductwork routing relatively straightforward. However, we frequently discover existing ducts that terminate in the attic rather than at a roof cap -- a code violation that causes attic mold. For first-floor bathrooms, we route ductwork through interior wall cavities or through the basement ceiling to an exterior wall vent. We always insulate ductwork in unconditioned attic spaces to prevent condensation.
