Replacing an over-the-range microwave with a range hood typically costs $500-$2,500, with many straightforward projects landing near $1,200. The final price depends mainly on hood type, whether an exterior duct already exists, cabinet and wall work, and local installation rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Hood and installation | $500 | $1,200 | $2,500 | Standard 30-inch hood, removal, and basic mounting |
| Range hood unit | $150 | $500 | $1,500 | Basic under-cabinet to premium insert or wall model |
| Installation labor | $200 | $450 | $900 | Higher if cabinet, duct, or wiring work is needed |
| Ducting and exterior vent | $0 | $300 | $1,000 | Existing usable duct may keep this expense near zero |
| Microwave removal and disposal | $50 | $125 | $250 | May be included in the installer’s quote |
What a 30-Inch Microwave-to-Hood Replacement Usually Costs
For a standard 30-inch cooking range, the typical total is $700-$1,800 when the new hood fits the existing cabinet space and the home already has suitable ductwork. A reasonable planning figure is about $1,200, including a midrange hood, removal, mounting, and minor connection work.
A low-cost conversion can run $500-$850 with a basic recirculating hood and uncomplicated installation. A ducted hood with new venting, cabinet changes, or electrical work can bring the total to $1,800-$2,500 or more. Prices generally assume standard residential access and no major wall or roof repairs.
The existing vent route and cabinet opening usually determine whether this is a simple appliance swap or a larger renovation.
Assumptions: U.S. residential project, standard 30-inch range, entry- to midrange hood, normal access, and no structural repairs.
How Hood, Labor, Ducting, and Removal Shape the Quote
Contractors may quote the work as one installed price or separate the hood, labor, and modifications. The table gives typical U.S. ranges; actual charges vary by equipment, access, and local trade rates. Confirm whether the quote includes removal, disposal, tax, and any patching.
| Cost item | Typical price | What changes the charge | Common unit rate |
|---|---|---|---|
| Range hood | $150-$1,500 | Style, airflow, noise rating, finish, and controls | $5-$50 per CFM |
| Installation labor | $200-$700 | Mounting difficulty and number of trades | $75-$150 per hour |
| Duct and exterior cap | $100-$600 | Route length, bends, wall or roof exit | $10-$30 per linear ft |
| Electrical changes | $100-$500 | Outlet relocation, new circuit, or hardwiring | $75-$150 per hour |
| Microwave removal | $50-$250 | Disposal, haul-away, and access | $50-$150 per unit |
| Cabinet or wall repair | $100-$700 | Cutting, reinforcement, trim, and finishing | $50-$125 per hour |
Labor commonly takes 2-5 hours for a direct replacement, while new ducting or cabinet changes may add several hours or require a separate electrician or carpenter. Costs can be higher if the installer must coordinate multiple visits or restore drywall, tile, or cabinetry.
Ask for a line-item estimate so equipment cost does not obscure separate duct, electrical, and finish-work charges.
How Duct Length, Cabinet Width, and Wiring Change the Price
Hood width should generally match the cooking surface: a 30-inch hood for a 30-inch range is common, while a 36-inch range may require a wider unit and cabinet changes. Moving from a microwave cabinet to a hood can leave exposed screw holes or an unfinished cabinet underside; trim or panel work may add $100-$500.
Ducting is a major variable. A short, straight 6-inch duct route may cost $150-$350 to connect or adapt, while a 10-20-foot run through a wall or roof can cost $400-$1,000, particularly if it needs several elbows or a new exterior cap. Long, narrow, or sharply bent ducts can also reduce airflow and may not meet the hood manufacturer’s specifications.
Hood airflow is measured in cubic feet per minute (CFM). Basic models often provide about 200-400 CFM, while higher-output units may reach 600-900 CFM and cost $500-$1,500. High-capacity equipment can require larger ducting, and some homes may need additional makeup air depending on local codes and the appliance’s capacity.
Electrical details matter because an over-the-range microwave may use an outlet inside the cabinet, while a new hood may connect differently. Reusing an appropriate existing connection may add little, but relocating an outlet or adding a circuit can cost $150-$500. Tile backsplashes, masonry, tight attic access, or a roof penetration can increase labor further.
Measure the range, cabinet opening, and proposed duct route before choosing a hood; a mismatch can turn installation into carpentry or vent construction.
Which Hood Choices Keep the Conversion Under Budget?
Choose a hood that fits the existing space and vent arrangement before comparing premium features. A basic under-cabinet hood generally costs $150-$400, while a midrange model with better lighting, controls, and quieter operation often costs $400-$900. Chimney-style wall hoods and custom inserts commonly run $700-$1,500 before installation.
A recirculating hood filters air through grease and charcoal filters and returns it to the room. It avoids the cost of adding an exterior duct, but it does not exhaust heat and moisture outdoors. A ducted hood carries cooking air outside and usually requires a compatible route; adapting an existing duct is less costly than creating one from scratch.
Other price differences include airflow, sound level, filter type, finish, and controls. For many everyday kitchens, a 300-600 CFM unit is sufficient, but the right capacity depends on the range, cooking habits, duct design, and manufacturer guidance. Paying extra for a very high CFM rating may not help if the duct cannot support the airflow.
Keeping the hood’s width and vent connection compatible with the current setup is often the most effective way to limit extra work.
How Long Installation Takes and When Extra Trades Are Needed
A direct replacement usually takes one installer 2-4 hours, including taking down the microwave, mounting the hood, and testing it. A two-person crew may be used to handle a heavy unit or reduce lifting risk. Typical labor rates for appliance or handyman work range from $75-$150 per hour, though some contractors charge a fixed installation fee.
New exterior ducting can extend the job to 4-8 hours or require separate appointments for roof, electrical, or cabinet work. A duct route through finished walls may involve cutting and patching, while a roof exit can require weatherproofing and additional access equipment. Ask whether the labor quote includes cleanup and testing of fan speeds, lights, and dampers.
Scheduling can also affect the estimate. A contractor may apply a $75-$200 minimum service or trip charge when the project is small, and emergency or short-notice work can carry a premium. Bundling duct or cabinet work with other kitchen repairs may reduce repeated travel fees.
For a reliable schedule and price, have the installer inspect the vent route and electrical connection before ordering the hood.
Regional Installation Rates and Ducting Can Shift the Total
Labor and permit charges vary across the United States. In many lower-cost Midwest and Southern markets, a basic installation may be about 5%-15% below the national midpoint. Major coastal cities and high-cost metro areas can run 15%-30% above it, especially when licensed electrical or roofing work is included.
Rural areas may have lower hourly rates but higher travel or delivery fees, often $50-$200. Urban projects can face parking, building access, and scheduling restrictions that add time. These differences are not fixed: contractor availability, local wage levels, and the amount of duct or finish work have more influence than the state alone.
Permit requirements depend on the scope and local rules. Replacing a hood without changing wiring or venting may not require a permit in some jurisdictions, while a new circuit, significant duct alteration, or roof penetration could trigger review. A permit or inspection allowance may add roughly $50-$300, but the local building department and contractor should confirm the applicable requirement.
Compare quotes from contractors who price the same hood, duct route, removal, and finish work rather than comparing labor totals alone.
Three Realistic Quotes for Replacing an Over-Range Microwave
These examples illustrate how scope changes the total. They assume a standard 30-inch range and typical residential labor; local rates and equipment selections can move each estimate. In each case, the hood price is separate from installation labor and listed modifications.
| Project | Hood and equipment | Labor and other work | Estimated total |
|---|---|---|---|
| Basic recirculating swap | $225 hood, filters included | 3 hours at $90 per hour, $75 removal | $570-$700 |
| Midrange ducted replacement | $600 hood, 400 CFM | 4 hours at $110 per hour, $250 duct adapter and cap, $100 disposal | $1,250-$1,550 |
| New exterior vent and cabinet repair | $900 hood, 600 CFM | 7 hours at $125 per hour, $650 ducting, $350 cabinet and wall finish | $2,500-$3,000 |
The lowest example assumes no exterior duct construction and a usable electrical connection. The middle estimate assumes an existing duct that needs adaptation rather than replacement. The high example includes a longer duct route and finish work; roof access, electrical upgrades, or code-required makeup air could increase it further.
Use the quote’s scope, not just its total, to determine whether two estimates are genuinely comparable.
Questions That Change a Microwave-to-Hood Estimate
A few details can reveal whether the estimate covers the complete conversion. Ask whether the hood is ducted or recirculating, whether the existing duct is compatible, and who verifies that its size and route meet the equipment requirements. Confirm the quoted hood model and whether filters, damper, exterior cap, and mounting hardware are included.
Check if microwave removal and disposal are included, and whether the installer will patch old fastener holes or exposed cabinet surfaces. Clarify who pays for an electrician if the connection needs to move, and whether drywall, tile, paint, or cabinet finishing is included or excluded. Written assumptions help prevent a low initial bid from growing after the microwave is removed.
Ask whether the contractor expects a permit, inspection, or additional ventilation work. If a project needs a roof opening or new circuit, have those items identified in the estimate rather than left as an open-ended allowance. A final price should state what happens if concealed damage or an unusable duct is found.
Request separate prices for the hood, removal, ducting, electrical work, and repairs to expose the true cost of each option.
How to Cut the Hood Conversion Price Without Losing Function
Keep the project close to a direct swap by selecting a hood that fits the existing 30- or 36-inch opening and can use the existing vent or electrical connection. Before buying, verify the hood’s discharge direction, duct diameter, mounting dimensions, and required clearance above the range. A low-priced unit that does not fit can create costly return visits or cabinet work.
Compare three written bids using the same hood model and identical scope. Check whether each price includes removal, disposal, duct adapters, exterior caps, electrical changes, and finish repairs. A bid that is $200 lower but excludes patching or duct modification may not be the least expensive completed project.
Choose capacity based on the range and duct route rather than automatically purchasing the highest-CFM model. If the existing duct is serviceable, ask whether cleaning or a small adapter is sufficient before agreeing to full replacement. Conversely, do not reuse a damaged, undersized, or poorly routed duct merely to avoid a short-term charge.
Homeowners can clear the work area, remove items from nearby cabinets, and protect counters before the crew arrives, provided the contractor approves. Avoid cutting cabinetry, altering wiring, or opening a roof or wall without confirming the installation requirements. Those tasks can damage finishes or create safety and code problems.
The strongest savings usually come from avoiding unnecessary duct, cabinet, and electrical changes while keeping required ventilation work in scope.
