Appliance Installation Q&A

Professional appliance installation costs $150-$600 depending on the appliance and hookup complexity. Standard drop-in replacements with existing connections: dishwasher $150-$300, refrigerator $100-$250, disposal $150-$250, washer/dryer $200-$400 for the pair. Premium installs: gas range $300-$600 (gas line connection and leak testing), built-in wall oven $400-$700 (cabinetry fitting), and new-construction hookups $500-$900. The cost drivers: whether water/gas/electrical hookups exist at the location (new runs add $300-$800 per utility), haul-away of the old unit ($20-$60 per appliance), and whether the installer must modify cabinetry or countertops. Appliance retailers often bundle installation with purchase ($100-$200 per unit), while independent appliance installers charge $85-$150/hour with a minimum visit fee. The honest comparison: paying $150-$250 for a professional install protects a $1,000-$4,000 appliance from warranty-voiding DIY damage — but if you're handy and hookups exist, most standard appliances are a 1-2 hour DIY job.

Refrigerator installation costs $100-$250 when water and electrical hookups already exist, including water line connection for the ice maker, leveling, and placement. If the refrigerator moves to a new location or the ice maker needs a new water line, add $200-$500 for a plumber. Counter-depth, built-in, and French-door models are heavier and bulkier — delivery teams charge $150-$300 for these because they need two-person handling and precise placement. The delivery-and-install bundle from retailers runs $100-$200 and includes haul-away of the old unit. DIY is realistic if you can move the old unit out and the new one in without scratching floors (furniture sliders help) — the connections are a water line and a plug. The common DIY mistake: kinking the water line or failing to seat the fridge level, which causes ice maker issues and door alignment problems. Freestanding refrigerators are the easiest appliance to install; built-in units are professional work.

Dishwasher installation costs $150-$300 for a standard drop-in replacement where water, drain, and electrical hookups exist. The work: disconnect the old unit, connect the water supply line ($15-$30 parts), drain line to the sink drain or air gap, electrical (hardwired or plug), slide in, level, and test. Full new installations — where the dishwasher is being added to a kitchen with no existing hookups — run $400-$700+ including a new dedicated circuit ($200-$400 electrician), water line run ($150-$350 plumber), and cabinetry modification ($100-$300). The common hidden costs: countertop or cabinet modifications for a slightly different-sized unit, disposal connection fees, and old unit haul-away. Installation is a well-known DIY project (2-4 hours, $30-60 in parts) if you're comfortable with a basic electrical connection — but hardwired units and homes with older wiring are safer with a pro. Retail installation bundles are often the cheapest route at $100-$180.

Gas range installation costs $300-$600, including connecting the gas line, leak testing with a pressure check or soap solution, leveling, and testing all burners. Homes without a gas stub-out at the range location need a gas line run — $300-$800 depending on distance, wall access, and whether the line runs through finished or unfinished space. The gas connection itself requires a licensed plumber or HVAC tech in most jurisdictions; a flexible appliance connector ($25-$50) is standard for the final connection. Gas range installs are not a DIY job unless you're experienced with gas fittings — an unsealed connection is a fire and carbon monoxide hazard, and incorrect work can void the range warranty and your home insurance. If converting from electric to gas, budget $500-$1,500 total: the gas line run plus a new 120V outlet for the igniter (ranges need power for electronic ignition). Always ask for proof of a leak test in writing.

Installing a washer and dryer pair costs $200-$400 when hookups are in place, covering water line connections, drain hose setup, dryer vent connection (or ventless dryer drain), leveling, and a test cycle. New venting for a gas or electric dryer adds $300-$900 depending on run length and whether the vent goes through an exterior wall or roof. Gas dryer installation runs $300-$500 extra because of the gas line connection and leak testing. Stackable units in a closet run $300-$500 (the stacking kit is $50-$150 and heavy lifting is involved). The classic hidden cost: the dryer vent — a crushed or lint-clogged vent is a fire hazard and the most common cause of poor drying performance; if the old vent is damaged, replacement is $200-$500. Retail installation bundles are $100-$250 for the pair and usually include haul-away. The DIY reality: hooking up washer lines is straightforward, but a gas dryer connection and any vent work are professional territory.

Over-the-range microwave installation costs $150-$350, including mounting, ducting (recirculating vs. vented), and electrical connection. Built-in wall ovens run $400-$700 because they require precise cabinetry fitting and a dedicated circuit (often 240V for electric ovens). Freestanding ranges and standard microwaves are the cheapest installs at $100-$200 when hookups exist. The complications that raise costs: new dedicated circuits for electric ovens ($300-$500 for an electrician to run a 240V line), cabinetry modification for built-in units ($200-$500), and venting work for range hoods and over-the-range microwaves ($150-$400 for ducting). Electric oven installs are where most DIY attempts fail — 240V connections need a licensed electrician in most jurisdictions, and the connection point is usually behind the unit in tight space. A new oven purchase from a retailer with install bundle runs $150-$300 total; an independent installer charges $85-$150/hour.

Garbage disposal installation costs $150-$250 for a standard replacement where the sink and electrical wiring are ready, including removing the old unit, installing the new one (sink flange, mounting ring, discharge tube to the drain), wiring the power connection, and testing. If the disposal is being added to a kitchen that never had one, the cost jumps to $400-$700: a new dedicated circuit ($200-$400), wiring under the sink, drain line modification, and sometimes a sink flange swap. The disposal unit itself runs $100-$300 (a 1/2 HP basic unit to a 1 HP with stainless grinding chamber), so a full new install with a mid-range unit lands around $500-$800. This is the most DIY-friendly appliance install in the kitchen: a replacement takes a DIYer 1-2 hours with basic tools and costs $25 in plumber's putty and wire nuts. The common mistakes that push people to call a pro: stripping the mounting ring, forgetting the dishwasher drain connection, and not resetting the breaker after a hardwire connection.

Haul-away is usually an add-on, not included in the base installation price. Many retailers include it for $20-$60 per appliance when bundled with purchase and delivery; independent installers charge $30-$80 per unit. Some municipalities require appliances to be recycled (refrigerators and freezers contain refrigerants that must be recovered by certified technicians — illegal to just dump), and bulk pickup days or utility recycling programs may take them free if you schedule it. When comparing quotes, always ask 'does this include haul-away?' — a $180 install quote can become $230 with disposal, or the old appliance stays on your curb. Refrigerator and freezer removal has real value: hauling a heavy fridge down stairs is a two-person job, and disposal fees for refrigerant appliances run $25-$75 at recycling centers. The smart move: negotiate haul-away into the install price (installers usually bundle it for $20-$40), and ask your utility about free appliance recycling programs in your area.
