CFM Requirements & Sizing Guide

⚠️

Critical Sizing Formula

Gas Ranges: Total BTUs ÷ 100 = Minimum CFM needed
Electric Ranges: Range width (inches) × 10 = Minimum CFM
Kitchen Volume: (L × W × H) ÷ 4 = Additional CFM consideration
Always use the HIGHEST calculated number!

Range Type/Size BTU Output Min CFM Required Recommended CFM
30″ Electric Range N/A 300 CFM 400-600 CFM
30″ Gas (4 burners) 40,000 BTU 400 CFM 600-800 CFM
36″ Gas (5 burners) 50,000-60,000 BTU 500-600 CFM 700-900 CFM
48″ Pro Range 80,000-100,000 BTU 800-1,000 CFM 1,200-1,500 CFM
60″ Commercial Style 120,000+ BTU 1,200+ CFM 1,500-2,000 CFM
Wok Burner (single) 25,000-35,000 BTU +250-350 CFM +400-500 CFM

Installation Components & Labor Costs

Understanding what drives installation complexity and pricing

Installation Services Breakdown

Service Component Cost Range Time Required Notes
Basic Hood Installation $300 – $500 2-3 hours Existing outlet & ductwork
Electrical Work (New Circuit) $250 – $500 2-4 hours Dedicated 20-amp circuit
Ductwork (New Install) $500 – $1,500 4-8 hours Through wall or roof
Duct Modification $200 – $600 2-3 hours Resize or reroute existing
Roof Venting $300 – $900 3-5 hours More complex than wall
Make-up Air System $300 – $1,200 4-6 hours Required for 400+ CFM
Cabinet Modification $200 – $500 2-3 hours Cut for hood or duct
Old Hood Removal $100 – $200 1 hour Disposal included
💡 Pro Tip: Island hoods cost 2-3x more to install due to ceiling work and longer duct runs. If your kitchen has a concrete slab ceiling, add $1,000-2,000 for drilling and reinforcement.

Ducting Requirements & Costs

Critical information for proper ventilation performance

Duct Size CFM Capacity Material Cost/ft Best Applications
4″ Round Up to 200 CFM $8 – $15 Small ductless conversions
6″ Round 200 – 400 CFM $10 – $20 Standard residential
8″ Round 400 – 600 CFM $15 – $25 Larger residential
10″ Round 600 – 1000 CFM $20 – $35 Professional ranges
3.25″ x 10″ Rect 200 – 300 CFM $12 – $22 Tight spaces
3.25″ x 14″ Rect 300 – 500 CFM $15 – $28 Between joists

Ductwork Performance Factors

📐

Length Impact

Add 1 CFM per foot

20 feet of duct = +20 CFM needed

Keep runs under 30 feet

Shorter = better performance

🔄

Elbow Penalties

Add 25 CFM per turn

Each 90° elbow restricts flow

Use 45° turns when possible

Maximum 3 elbows recommended

🏠

Termination Caps

Add 40 CFM for roof cap

Wall caps: Less restriction

Roof caps: More weatherproof

Must have backdraft damper

Noise Levels (Sones)

1-3 sones: Ultra quiet ($$$)

4-6 sones: Normal conversation

7-10 sones: Noticeable but OK

10+ sones: Very loud

Remote blowers = quieter

Real Estate Investment Analysis

Strategic ventilation choices for different property types

🏠

Single-Family Rental

Best Option: Basic ducted under-cabinet

Target: $500-800 total

CFM: 300-400 adequate

Skip: Smart features, designer looks

ROI: Required for code, no rent premium

🔄

Fix & Flip

Sweet Spot: Stainless chimney style

Budget: $700-1,200

Focus: Visual impact + proper CFM

Worth it: LED lighting, quiet operation

Impact: Kitchen feels complete

🏖️

Short-Term Rental

Go Big: Statement hood matters

Budget: $1,500-3,000

Features: Ultra-quiet, great lighting

Style: Match high-end appliances

Benefit: Prevents smoke complaints

📊 Market Insight: Proper ventilation is CODE REQUIRED in most areas for gas ranges. In rentals, focus on function over form. For flips, a $1,000 chimney hood adds $2,000+ in perceived value. Professional-grade hoods (1000+ CFM) only make sense for $750K+ homes.
💡

Money-Saving Strategies

Smart ways to reduce costs without sacrificing performance

🔌

Ductless If Possible

Save $500-1,500 on ductwork. Modern charcoal filters work well for light cooking. Replace filters every 3-6 months ($20-40 each).

📏

Right-Size Your CFM

Don’t overbuy – 600 CFM handles most home cooking. Higher CFM = more noise, higher cost, makeup air requirements.

🛠️

Keep Existing Ductwork

If current duct is 6″+8″, it likely works for new hood. Cleaning existing ducts ($150) beats new installation ($500-1,500).

⚡

Use Existing Electric

Most hoods run on standard outlet. Only high-CFM models need dedicated circuit. Saves $250-500 on electrical work.

🏪

Buy During Sales

Black Friday/Memorial Day = 30-50% off. Buy hood only, install later. Restaurant supply stores have deals on pro models.

🎨

Convertible Models

Ducted/ductless convertible gives flexibility. Start ductless, add ducting later during renovation. Same hood, staged investment.

Frequently Asked Questions

Expert answers about range hood selection and installation

How do I calculate the right CFM for my kitchen?
Use three calculations and pick the highest: (1) For gas: Total BTUs ÷ 100 = CFM. (2) For electric: Range width in inches × 10 = CFM. (3) For room size: (Length × Width × Height) ÷ 4 = CFM. Example: 40,000 BTU gas range needs 400 CFM minimum, but if your kitchen is 15×12×9 feet, that’s 405 CFM. Add duct losses: +1 CFM per foot of duct, +25 per elbow, +40 for roof cap.
Do I really need a range hood or can I just open windows?
Most building codes REQUIRE mechanical ventilation for gas ranges – windows don’t count. Even for electric, range hoods remove grease, moisture, and odors that windows can’t handle effectively. Cooking without proper ventilation leads to greasy cabinets, peeling paint, and poor indoor air quality. The investment protects your kitchen and health.
What’s the difference between ducted and ductless range hoods?
Ducted hoods vent air outside through metal ductwork – most effective for removing heat, moisture, odors, and grease. Ductless recirculate air through charcoal filters – easier to install but only remove some odors and no moisture/heat. Ducted is always preferred if possible. Ductless works for apartments or light cooking only.
Why do island range hoods cost so much more?
Island hoods require: (1) Running ductwork through the ceiling (complex), (2) Structural support from ceiling/attic, (3) Longer duct runs reducing efficiency, (4) Often need higher CFM due to open design, (5) Electrical run through ceiling, (6) More expensive decorative designs. Labor alone is often $1,000+ vs $300 for wall-mount.
Can I install a range hood myself?
Simple ductless or replacement hoods: Yes, with basic tools and electrical knowledge. New ducted installation: Not recommended – requires cutting holes in walls/roof, proper duct sizing, electrical work, and permits. Mistakes can cause fire hazards, water leaks, or carbon monoxide issues. Professional installation ensures code compliance and proper function.
What is make-up air and do I need it?
Make-up air replaces air exhausted by your range hood, required by code for hoods over 400 CFM. Without it, negative pressure can: backdraft water heaters/furnaces (dangerous!), make doors hard to open, and reduce hood efficiency. Systems cost $300-1,200 installed. Alternative: choose under 400 CFM hood or crack a window while cooking.
