Frequently Asked Questions
How much does bathroom fan installation cost in Texas?
Replacing an existing fan costs $150 to $350 in Texas when the housing and ductwork are already in place. Installing a brand-new fan where none exists costs $350 to $700 because it requires cutting a ceiling opening, running ductwork to an exterior vent, and wiring the switch. Combo units with lights or heaters run $300 to $600 installed.
Is a bathroom exhaust fan required by code in Texas?
Texas follows the International Residential Code, which requires mechanical ventilation in bathrooms without an operable window. Even bathrooms with windows benefit from an exhaust fan because Texas humidity levels make natural ventilation insufficient for preventing mold. Most local building codes require a minimum 50 CFM fan for standard bathrooms.
What size exhaust fan do I need?
The standard rule is one CFM per square foot of bathroom floor area, with a minimum of 50 CFM. A typical 8-by-10-foot bathroom needs an 80 CFM fan. For bathrooms with separate shower enclosures, jetted tubs, or steam showers, you need higher CFM ratings. A professional will calculate the exact requirement based on your bathroom dimensions and features.
Why is my bathroom fan so loud?
Noisy bathroom fans are usually older models rated at 3 to 4 sones. Modern fans operate at 0.3 to 1.0 sones and are nearly silent. Other causes of noise include loose mounting hardware, debris in the fan blades, a worn-out motor, or undersized ductwork creating back pressure. Replacing an old fan with a modern unit dramatically reduces noise.
Can a bathroom fan vent into the attic?
No. Venting a bathroom fan into the attic is a code violation in Texas and a common source of moisture damage. The warm, humid air condenses on cold attic surfaces, causing mold growth and wood rot. All exhaust fans must vent to the building exterior through a wall cap or roof vent. If your fan vents into the attic, it should be rerouted immediately.
How long does bathroom fan installation take?
Replacing an existing fan in the same housing takes one to two hours. A new installation requiring ceiling cutting, duct routing, and electrical wiring takes three to five hours depending on attic access and the distance to the nearest exterior wall. Most installations are completed in a single visit with cleanup included.
