Appliances: what to know before you hire
Appliance installation looks like plug-and-play, but the hookups are where it goes wrong: a gas line, a water line, a dryer vent, or an anti-tip bracket done carelessly is a leak, a fire, or a tip-over waiting to happen.

How the work actually works
The appliance is the easy part — the connection is where safety lives. Here's what a correct hookup includes for each type.
- 1
Confirm fit and the utility
Measure the opening and the doorways, and confirm the right hookup exists: a gas line and shutoff, a water line, a 240V circuit, or a vent. Adding any of these is the real work.
- 2
Connect to code with a shutoff
Gas with a flexible connector and a shutoff valve, leak-tested; water with a proper valve and braided line; electric on the correct circuit. Hardwired vs. cord-and-plug depends on the appliance and code.
- 3
Vent and secure
Dryers get a short, smooth, rigid vent run to the outside (lint is a fire hazard); ranges get an anti-tip bracket; the appliance is leveled.
- 4
Test and haul the old one
Run it, check for leaks and proper drainage, and remove the old appliance.
Hookup types — and the safety catch on each
What 'install' includes — and the thing that's dangerous to skip — depends entirely on the connection.
- Plug-in (fridge, microwave)
- The simplest — but a fridge ice-maker/water line needs a proper valve and braided line to avoid a slow leak, and a built-in needs exact clearances.
- Gas (range, cooktop, dryer)
- A flexible gas connector and a shutoff valve, leak-tested. Gas is the one to never wing — a permit and a leak check are non-negotiable.
- Water (dishwasher, washer, ice maker)
- A dedicated shutoff and braided steel lines, plus a proper air gap or high loop on a dishwasher drain so wastewater can't back-siphon.
- Dryer vent
- A short, smooth, rigid metal duct to the outside — never the flexible foil kind buried in a wall. Lint buildup in a bad vent is a leading house-fire cause.
- Hardwired / 240V (range, oven, dryer)
- Big appliances often need a dedicated 240V circuit; cord-and-plug vs. hardwired, and the right breaker, matter.
The safety items people skip
These small details are the difference between a clean install and a hazard.
- Anti-tip bracket (ranges)
- A bracket that keeps a range from tipping when weight is on an open door — code, and routinely skipped on quick installs.
- Dryer vent length and material
- Long, kinked, or foil vents trap lint and overheat. Keep it short, rigid, and terminated outside.
- Gas leak test
- Every gas connection should be soap-tested or metered for leaks before it's used.
- Dishwasher air gap / high loop
- Prevents dirty sink water from siphoning back into the dishwasher.
Red flags of a corner-cut job
- Gas appliance hookups with no leak test or no shutoff valve.
- A flexible foil dryer vent, or a long kinked run hidden in the wall.
- A range installed with no anti-tip bracket.
- A dishwasher drain with no air gap or high loop.
- An undersized circuit, or the wrong cord/breaker, on a 240V appliance.
Put it in writing
- A shutoff valve and a leak test on every gas connection.
- A short, rigid, outside-vented dryer duct.
- The anti-tip bracket installed on ranges.
- Braided water lines, a shutoff, and a dishwasher air gap or high loop.
- Haul-away of the old appliance included.
Talk like a pro
The terms a contractor uses — so you can follow the conversation and ask the right questions.
- Shutoff valve
- A local valve to isolate the appliance's gas or water without killing the whole house.
- Anti-tip bracket
- A floor or wall bracket that stops a range from tipping forward.
- Dryer vent (rigid vs. foil)
- Smooth rigid duct (safe) vs. flexible foil (a lint trap and fire risk).
- 240V circuit
- The high-voltage dedicated circuit big appliances need.
- Air gap / high loop
- A dishwasher drain detail that prevents wastewater back-siphoning.
What drives the cost
- Connection type — a simple plug-in vs. gas, water, or hardwired
- Whether the hookup already exists or must be run (gas line, water line, 240V circuit, vent)
- Fit and clearances (counter-depth, cutouts, doorways)
- Haul-away of the old appliance

What should a appliances quote actually include?
A good quote names the materials, the spec or grade, and the scope of work — not just one lump-sum number. The more a bid leaves vague, the more room there is for surprise costs and cut corners. The checklist above lists exactly what to put in writing for this kind of work.
