Converting gas to induction: the real cost ($1,400-$4,800 total), the electrical upgrade path, gas-line capping, cookware swap, and whether it's worth it for your kitchen in 2026.
A step-by-step cooktop installation guide covering electrical, gas, cutout dimensions, venting and code — by a licensed electrician and gas-fitter with 20+ years in kitchens.
Two rules decide range hood CFM: 100 per linear foot for induction and electric, 1 per 100 BTU for gas. Sizing tables by cooktop width, plus why the number on the box is not what reaches your kitchen.
Ductless hoods filter odor and grease but remove zero moisture and zero combustion byproducts. Why that disqualifies them over gas, why induction is the honest exception, and what they really cost.
Rigid metal duct, never flex. Never reduce below the hood outlet. Each 90-degree elbow costs 15 equivalent feet. The duct rules that decide whether a 600 CFM hood delivers 600 CFM or 400.
A kitchen exhaust system capable of exceeding 400 CFM triggers a makeup air requirement in IRC jurisdictions. What the code says, why backdrafting is the real hazard, and what a system costs.
