Range Hood Not Working in Houston: Causes and Fixes
A range hood (also called a kitchen exhaust fan or vent hood) that stops working creates real air quality problems in Houston kitchens — especially in the summer months when cooking generates heat, steam, and cooking odors that need to be expelled quickly. Range hood problems range from simple fixes you can do yourself to more complex repairs that require a technician. Here is a complete guide to diagnosing and fixing a non-working range hood.
Types of Range Hoods We Service
Houston kitchens have a wide variety of range hood configurations. Ducted range hoods exhaust air outside through ductwork — the most effective type for removing heat, smoke, and cooking odors from the kitchen. Ductless (recirculating) range hoods filter air through charcoal filters and return it to the kitchen — less effective than ducted but necessary when ductwork installation is not practical. Under-cabinet range hoods are the most common type in Houston tract homes. Wall-mount and island hoods are common in open-concept Houston kitchens and renovated homes. We service all types, including premium brands like Broan, Zephyr, Kobe, Hauslane, and Faber.
Common Range Hood Problems in Houston
Fan not running at all — Check the power source first. Range hoods typically plug into an outlet inside the cabinet above the hood, or are hardwired. Check that the outlet has power using a phone charger or small appliance. If power is confirmed, the issue is internal: a failed fan motor, a burned-out capacitor that starts the motor, or a failed control switch. Fan motor replacement costs $60 to $150 plus labor depending on the hood model. Fan runs but has no suction — For ducted hoods, check that the damper (the flap that opens when the fan runs) is not stuck closed. Houston's humid air can cause aluminum dampers to corrode and stick. Also verify the ductwork is not clogged with grease buildup — a very common issue in Houston homes where cooking is frequent. Grease accumulates inside ductwork over years of use and can completely block airflow. Light not working but fan works — Almost always a burned-out bulb. Most range hoods use halogen or LED bulbs specific to the model. Check the model number and order the correct replacement. If the new bulb does not work, the light socket or the control board's lighting circuit has failed. Fan is very loud — Loud range hoods in Houston homes are often caused by grease buildup in the fan wheel (impeller), which causes imbalance and vibration. Cleaning the fan wheel is often enough to restore quiet operation. Other causes include worn fan motor bearings, a loose fan wheel set screw, or a fan wheel that has contacted a deformed motor housing due to heat damage.
Grease Filter Maintenance
Houston kitchens generate significant grease from cooking — particularly in households that regularly fry, grill, or use high heat cooking methods. Range hood filters should be cleaned monthly in heavy-use Houston kitchens (every 2 to 3 months for average use). Clogged grease filters dramatically reduce hood effectiveness and force the fan motor to work harder, shortening its lifespan. Aluminum mesh filters can be run through the dishwasher. Charcoal filters in ductless hoods must be replaced rather than cleaned — typically every 3 to 6 months in Houston's cooking-heavy households.
When the Ductwork Is the Problem
In older Houston homes and many post-hurricane-Harvey renovated homes, range hood ductwork may be undersized, incorrectly routed, or partially disconnected. Ductwork problems cause the fan to run but provide inadequate ventilation. Signs of a ductwork problem: food odors and steam linger in the kitchen after cooking even with the hood running, the fan sounds normal but you do not feel airflow at the exterior exhaust vent. We inspect and test ductwork as part of any range hood service call.
