Labor to install a microwave typically costs $100-$250 for an over-the-range model, with simpler countertop setups costing less and built-in installations costing more. The final price depends on microwave type, cabinet fit, venting, wiring, local labor rates, and whether an old unit must be removed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Countertop setup | $0 | $40 | $75 | Placement and basic setup; usually no mounting |
| Over-the-range installation labor | $100 | $175 | $300 | Existing compatible cabinet and electrical connection |
| Built-in installation labor | $200 | $350 | $600 | Trim kit, cabinet fit, or adjustments can add time |
| Electrical work, if needed | $150 | $275 | $500+ | Separate electrician charge for circuit or outlet changes |
Assumptions: Typical U.S. pricing, standard-size appliances, normal access, and no major cabinet reconstruction.
Labor prices for countertop, over-range, and built-in microwaves
Countertop microwaves generally require no installation labor beyond positioning and checking the outlet, so setup may be free with delivery or cost $25-$75 as a standalone visit. An over-the-range microwave commonly costs $100-$250 in labor when an existing unit is replaced and the mounting plate, cabinet, and vent connection are compatible.
Built-in models usually require more precise fitting and a trim kit, putting labor around $200-$500; custom cabinet changes can push it above $600. For a typical replacement over a range, budgeting about $175 for labor is reasonable. Appliance purchase, delivery, and parts are usually additional.
What the installation quote includes beyond mounting
A quote may include removing the old microwave, attaching the mounting plate, lifting and securing the new unit, connecting an existing plug, and testing the fan and controls. Clarify whether the quoted fee covers all those steps or only mounting. A second worker may be required to lift a heavy over-the-range model, and some installers charge separately for travel or removal.
| Quote item | Typical charge | What changes the price |
|---|---|---|
| Mounting and connection labor | $100-$250 | Model type, access, and fit |
| Old microwave removal | $25-$100 | Weight, disposal, and haul-away service |
| Vent adapter or mounting hardware | $15-$80 | Included parts and duct configuration |
| Cabinet or trim adjustment | $50-$300 | Cutting, shimming, or additional carpentry |
| Electrical modification | $150-$500+ | Outlet relocation or new circuit requirements |

Cabinet width, vent routing, and wiring that change labor
Most over-the-range models are designed for a 30-inch cabinet opening. A narrower or uneven opening, weak cabinet bottom, or missing wall support may require carpentry or reinforcement, adding roughly $50-$300 and one or more labor hours. Existing ductwork that aligns with the microwave is usually the least expensive setup; changing from recirculating to external venting can add $100-$400 for duct and cabinet work.
Electrical conditions matter, too. Plugging into an accessible, correctly positioned outlet is part of many basic jobs, while relocating an outlet or adding a dedicated circuit requires an electrician. Installation labor rises fastest when the opening, vent, or power connection does not match the appliance.
How to lower the microwave installation labor bill
Before booking, confirm the new model’s width, depth, mounting pattern, and vent direction against the existing space. Keeping the same appliance type and vent route can avoid carpentry and duct changes. Clear the countertop and cabinet, empty the old unit, and make the outlet accessible; ask the installer whether these preparations reduce the service charge.
Compare quotes that list removal, hardware, testing, and travel fees separately. Bundling microwave installation with other appliance work may reduce a minimum service-call charge, but compare the combined price with individual quotes. Avoid paying for cabinet alterations or external venting unless the selected model and home setup require them.
How regional labor rates shift the installation quote
Labor prices tend to be higher in major metropolitan areas and regions with high contractor demand. A straightforward job in a lower-cost rural market may come in 10%-20% below national averages, while urban rates can run 15%-30% higher. These differences usually affect the service-call minimum and hourly labor more than the price of standardized mounting parts.
Rates also vary by provider: an appliance retailer’s installation package may have a fixed fee, while an independent installer may charge an hourly rate plus a minimum visit. Compare the full installed-labor quote, not just the advertised mounting fee. Ask whether sales tax applies to labor or materials in the local jurisdiction.
How many hours a microwave installation takes
A direct replacement over an existing range often takes 1-2 hours for a two-person crew. A built-in installation may take 2-4 hours when installers need to fit a trim kit or make small adjustments. Unplanned cabinet repairs, a difficult lift, or vent changes can extend the visit and trigger additional labor.
Some providers use a fixed installation price; others calculate labor from time on site. A common planning range for an independent installer is $50-$100 per hour, with minimum charges that may cover the first hour or travel. Ask how extra time is billed before work starts.
Old-unit removal and electrical work add separate charges
Removal of an existing microwave may add $25-$100 if it is not included, while haul-away or recycling can carry another fee. Difficult access, a high cabinet, or a unit secured with corroded fasteners can add labor. If the microwave is hardwired or the outlet is behind the appliance and inaccessible, the installer may require an electrician rather than include wiring changes in the mounting price.
Electrical upgrades commonly add $150-$500 or more, depending on whether the work involves moving an outlet, extending wiring, or installing a circuit. Confirm that any electrical change is quoted by a qualified electrician and itemized separately.
Replace, repair, or switch microwave types
Replacing an over-the-range microwave with a similar model is usually cheaper than switching to a built-in unit or changing the vent configuration. A repair may make financial sense for a relatively new appliance with a minor fault, but a failed magnetron or control board can cost $150-$400 for parts and labor. Compare the repair quote with the replacement appliance price and installation fee.
Changing from an over-the-range unit to a countertop model can reduce installation labor, but it may leave cabinet or wall repairs and requires a suitable counter location. Compare the full project cost, including removal and any space changes, before choosing a different configuration.
