La Cornue Cascade Hood Repair in San Francisco

Cascade is a CornuFé hood, listed at 36 inches and 44 inches. A hood’s job is simple: pull cooking air up, through the filters and out of the house. When that stops happening, the whole kitchen shows it in smell, steam on the windows and a film on the cabinets.

Reading the symptom: weak pull

Hold a sheet of tissue near the filters with the fan on. If it barely moves, think in order. Are the filters coated? Is the duct blocked or crushed? Is the blower spinning below full speed? Is the room short of make-up air, so the hood is fighting a sealed kitchen? Only the last three need a technician.

Reading the symptom: the hood sounds wrong

A roar usually means air is being forced through a restriction. A rattle points to something loose in the housing or an unbalanced wheel. A scraping note is a motor or bearing that we want to see before it fails completely. Describe the sound and which speed produces it; that single detail saves a lot of time.

Where the air goes

In a Cascade installation the duct run matters as much as the hood. San Francisco townhouses often route through long vertical chases, while wine-country homes may vent through a roof cap exposed to weather. Dampers that stick closed are a classic cause of a hood that runs happily and moves nothing. We trace the run from hood to outside.

Owner checks

• Wash the filters and let them dry fully before refitting.
• Check that the outside cap is not blocked, from the outside and only where you can see it from the ground.
• Run the hood on each speed and write down any change.
• Check the breaker position.

Do not remove the housing or touch wiring. Burning smell means breaker off.

What a diagnosis covers

The visit starts with listening, then filters, then the path of the air to the outside. We note what we find at each stage, so you can see why we reached our conclusion and what the repair would involve before you approve it.
