Home Depot microwave installation typically costs about $150-$300 for a straightforward over-the-range replacement, not including the appliance. With a new microwave, the total commonly falls between $300 and $900; cabinet changes, electrical work, or duct modifications can push it higher.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installation labor | $150 | $225 | $400+ | Standard replacement versus added work |
| Over-the-range microwave | $150 | $350 | $700+ | Price varies by capacity and features |
| Installed project total | $300 | $575 | $1,100+ | Before major electrical or cabinet repairs |
What Home Depot charges for an over-the-range microwave
For a like-for-like over-the-range (OTR) replacement, budget roughly $150-$300 for installation, with a typical planning figure near $225. The microwave itself often costs $150-$700, making a basic installed project around $300-$900 before optional services. Home Depot service availability and the final quote can vary by ZIP code, appliance, and installation conditions.
These estimates assume an existing compatible opening, usable electrical outlet, and standard mounting and venting. A countertop model generally needs no installation beyond placement and plugging it in, so its project cost is usually the appliance price alone. Assumptions: U.S. home, standard OTR replacement, normal access, no cabinet or wiring changes. Confirm the service scope and total before scheduling; the appliance price and installation charge are separate.
Which mounting, venting, and labor charges appear on the quote
A written estimate should identify what the installation price includes and which extras are separate. The following ranges are planning estimates, not guaranteed Home Depot rates; local service terms may differ.
| Quote item | Typical range | What it covers | Possible extra |
|---|---|---|---|
| Installation labor | $150-$300 | Remove old unit, mount replacement, connect existing setup | Complex mounting or extra labor |
| Mounting hardware | $0-$50 | Standard bracket or small hardware needs | Missing or incompatible parts |
| Vent adaptation | $0-$150 | Connect to a compatible existing duct | New ductwork or vent relocation |
| Old-unit removal | $30-$100 | Haul-away where offered | Local disposal charges |
| Electrical work | $0-$300+ | Existing suitable outlet assumed | New outlet, circuit, or electrician visit |
Separate trades or code work may be quoted outside the installer’s standard service. Ask whether removal, disposal, vent connection, and testing are included rather than assuming they are part of the base fee.
Cabinet width, duct route, and outlet location can change the price
Most OTR models are designed for openings around 30 inches wide. A narrower or wider opening, unusual cabinet depth, damaged cabinet bottom, or missing mounting support can require carpentry or a different appliance. An opening that needs cutting or reinforcement may add roughly $75-$300, depending on the work and local labor.
Venting is another major variable. Reusing a compatible exterior duct is usually simpler than switching between rear, top, or recirculating exhaust. New duct sections or a relocated exterior vent can add $100-$500 or more. A microwave that requires a dedicated outlet when none exists may need electrician work, often adding $150-$400 or more depending on access and circuit capacity.
Capacity and weight matter when checking fit. A 1.6-2.2-cubic-foot unit may have different clearance and mounting requirements than a compact model; the product’s installation specifications should match the cabinet and cooktop clearances. Measure the opening and check the vent direction, outlet, and mounting surface before ordering.
How long the installer may need at your home
A direct replacement commonly takes about 1-2 hours once the site is ready. Removing a heavy unit, correcting a misaligned bracket, or adapting the duct can extend the visit to 2-4 hours; significant cabinet or electrical work may require another trade and a separate appointment. Typical independent labor rates for added work: about $75-$125 per hour, varying by market.
Home Depot’s service provider may use a flat installation price rather than bill by the hour, so added time does not automatically mean an hourly charge. The estimate should state how extra work is authorized and priced. Have the old appliance cleared and the installation area accessible to reduce avoidable labor delays.
Removal, vent changes, and electrical work raise the total
Old-microwave haul-away may be included in a package or charged separately, and availability differs by location. If it is not included, allow around $30-$100 for removal or disposal. Confirm that the service includes disconnecting and taking away the old unit, not just unbolting it.
More extensive costs arise when the new model cannot use the existing duct, the outlet is inaccessible, or the cabinet needs repair. A new exterior vent route can exceed $500 when it involves wall or roof penetration, while electrical upgrades can reach several hundred dollars. Get approval and a separate price for any work beyond the booked installation before it begins.
OTR installation costs more than plugging in a countertop model
A countertop microwave usually costs $80-$300 and requires little or no paid installation. A built-in or drawer microwave can cost $500-$2,000 for the appliance, with installation often adding $300-$1,000 or more because cabinetry, trim, and electrical work may be involved. These alternatives are not direct substitutes if the kitchen requires an OTR unit to provide ventilation or free counter space.
For a rental or temporary setup, a countertop model can avoid mounting and duct expenses if there is a safe, appropriate outlet and adequate ventilation around the appliance. Compare the full installed price—not just the microwave sticker price—when choosing between appliance types.
Three example budgets for common Home Depot installs
| Job example | Appliance | Installation and extras | Estimated total |
|---|---|---|---|
| Basic OTR swap, existing vent | $200-$350 | $150-$250 | $350-$600 |
| Midrange OTR, haul-away included | $350-$550 | $200-$350 | $550-$900 |
| OTR replacement with duct or outlet work | $300-$700 | $350-$900 | $650-$1,600 |
Totals vary with model, local service pricing, and whether extra work is necessary. The third example includes an allowance for one or more site modifications, not a guarantee that all electrical or vent projects fit within that range. Use these figures to evaluate a quote, then verify each included task with the local installer.
How to lower the microwave installation bill
Choose a replacement that fits the existing 30-inch opening, mounting arrangement, and vent route. Matching the old unit’s exhaust direction and using an existing suitable outlet can prevent carpentry, duct, or electrical charges. Compare appliance dimensions and installation requirements before purchase, not after delivery.
Request an itemized quote and compare the installation package with local licensed contractors, ensuring both estimates cover the same removal, mounting, vent connection, and testing. Avoid paying for features that do not address the household’s needs, but do not skip required electrical or clearance corrections. The most reliable savings usually come from a compatible replacement and a clearly defined scope.
