Is your old range hood rattling like a jet engine? Or perhaps it simply looks outdated in your newly renovated kitchen. Replacing a range hood is one of the most high-impact DIY projects you can undertake. It instantly improves air quality, removes odors, and elevates the aesthetics of your cooking space.
While it involves electricity and heavy lifting, it is entirely manageable with the right guidance. As experts in kitchen ventilation, we have broken down the process into safe, manageable steps.
In this guide, we will walk you through removing the old unit, installing the new one, and—crucially—teach you the professional method for maintaining your filters to ensure your new appliance lasts for decades.
Upgrade your kitchen in an afternoon with the right tools.
Phase 1: Preparation & Safety First
Before you touch a screwdriver, safety is paramount. You are dealing with electricity near metal.
⚠️ CRITICAL SAFETY STEP:
Go to your home's circuit breaker panel and turn off the power to the kitchen. Use a non-contact voltage tester to verify the wires are dead before proceeding.
Tools You Will Need:
- Power Drill & Drill Bits
- Stud Finder (Essential for heavy hoods)
- Level
- Wire Nuts & Electrical Tape
- HVAC Aluminum Tape (Not duct tape)
- Screwdrivers (Phillips and Flathead)
- Safety Goggles & Gloves
Phase 2: Removing the Old Unit
Removing the old hood is often harder than installing the new one due to grease buildup and stuck screws.
- Remove Filters & Cover: Take out the grease filters and the bottom cover to access the wiring.
- Disconnect Wiring: Unscrew the wire nuts connecting the hood to the house supply. Separate the black (hot), white (neutral), and green/copper (ground) wires.
- Support the Hood: Do not do this alone. Have a helper hold the weight of the hood.
- Unscrew & Lower: Loosen the screws holding the hood to the cabinet or wall. Gently lower it down.
Phase 3: Installing Your New Brano Hood
Now for the exciting part. Whether you have a Wall Mount or Under Cabinet model, the principles are similar.
Step 1: Mark & Measure
Use the paper template provided in your Brano box. Tape it to the wall/cabinet. Mark your screw holes and the electrical knockout location. Ensure the hood will sit 28-32 inches above the cooktop.

Step 2: Install Anchors or Bracket
If installing a wall mount hood, screw the mounting bracket securely into the wall studs. If studs aren't available, use heavy-duty toggle bolts (drywall anchors are rarely strong enough for heavy motors).
Step 3: Connect the Vent
If you are venting outdoors, connect the hood's damper to your home's ductwork. Use HVAC Aluminum Tape to seal the joints airtight. Do not use duct tape; heat will make the adhesive fail.
(Installing a ductless model? You can skip the venting step, but ensure your diverter is set to recirculate.)
Step 4: Electrical Wiring
Match the wires color-for-color inside the junction box:
- Black to Black (Live)
- White to White (Neutral)
- Green/Bare to Green Screw (Ground)
Secure connections with wire nuts and wrap with electrical tape.

Reading is great, but watching is better. We have created dedicated installation videos for every Brano model to help you visualize the process.

Congratulations! Your hood is installed. But to keep it running like new, you must master the art of filter maintenance. A clogged filter reduces CFM power by up to 50%.
How to Deep Clean Metal Filters (The "Sink Bath" Method)
Whether you have stainless steel Baffle filters or aluminum Mesh filters, this is the gold standard for cleaning.

Managing Carbon Filters (For Ductless Owners)
If you installed your hood without a duct, you have charcoal filters inside.
⛔ DO NOT WASH: Activated carbon cannot be washed. Water destroys the carbon structure.
You must replace these every 3 to 6 months depending on cooking frequency. Set a calendar reminder on your phone now!

Frequently Asked Questions (Installation & Care)
1. Can I replace a range hood myself?
Yes, if you have basic DIY skills. However, because hoods are heavy and bulky, you will need a second person to help lift and hold the unit while you secure it.
2. How long does it take to replace a range hood?
For a straightforward replacement (same size, same venting), it typically takes 1 to 3 hours. If you need to cut new ductwork, it will take longer.
3. Are range hoods hardwired or plug-in?
Most Brano hoods come with a standard 3-prong plug for easy installation. However, you can cut the plug and hardwire it if your kitchen setup requires it (always follow local codes).
4. How high should I mount my new range hood?
The standard height is 28 to 32 inches above the cooktop. Gas stoves usually require a minimum of 30 inches for safety.
5. Do I need to turn off the electricity?
Yes! Absolutely. Turn off the circuit breaker for the kitchen before touching any wires. Verify the power is off with a voltage tester.
6. Can I put range hood filters in the dishwasher?
Stainless steel baffle filters are generally dishwasher safe. Aluminum mesh filters can be washed but may discolor (turn grey) due to the detergent chemicals.
7. How often should I clean the filters?
Ideally, every 3 to 4 weeks. If you cook with a lot of oil or fry food often, you may need to clean them every 2 weeks.
8. What if my duct size is different from the new hood?
You can use a duct reducer/adapter (e.g., 8-inch to 6-inch), but be aware that reducing the duct size may slightly increase noise and reduce airflow efficiency.
9. Can I vent my range hood into the attic?
No. Never vent into an attic or crawlspace. The warm, moist grease will cause mold and rot. You must vent completely outside or use a ductless recirculation kit.
10. Why is my new hood vibrating?
Vibration is usually caused by loose mounting screws, an unbalanced fan blade, or a foreign object (like a screw) stuck in the blower wheel. Double-check your installation.
