Upgrading your appliances is an exciting event. The installation, though? It’s a whole different ball game when your starting lineup consists of plugs, cords, hoses, and outlets. And why are there always too many screws in the box? With the right tools and knowledge, installing an appliance can be simple—fun, even. Here are some tips to help you get a DIY appliance installation right the first time.

1. Measure Before Buying

Stop! Before you buy any appliance, measure. Then measure again. If you feel like measuring a third time, we won’t judge. The perfect appliance is one that fits where you need it (including when the door swings open). Refrigerators, for example, should have room to open to at least a 135-degree angle to access the drawers or change the water filter. If you’re buying online, review the product specs, and if you’re going to the store, bring them with you.

2. Read the Manual

You may want to shove it in a drawer with all the other manuals, but give it a look-through before you send it off to the island of lost things. The manual is your installation lifeline, and reading it will ensure you don’t void any warranties. Improper installation—even missing one small detail—can completely void some manufacturer warranties. 

3. Think About Your Doors and Hallways

Doors might be the most finicky aspect of a DIY install. Measure your home doorways and hallways to confirm that you can maneuver the appliance through your home to its final location. You may need to take the doors off of an appliance (like a refrigerator) to get it into the kitchen, and it’s best to know this before strapping it onto the dolly.

4. Gather Your Tools and Accessories

If your appliance requires tools for the installation, make a list of what you need beforehand, such as new plugs, pipes, or vents. You’ll almost certainly want to grab a level, wrenches, screwdrivers, a tape measure, and a hammer. The instruction manual for your new appliance is a good place to find what tools you’ll need, and some companies have this information listed on their websites.

5. Check the Wattage

Most newer electric appliances are energy-rated for efficiency, which means they’ll actually require a lower wattage. Most (but not all) appliances will not need any new circuits, but check the wattage rating on your new appliance just to be sure. If you do need a new circuit, the best thing to do is consult an electrician near you to install the right circuit for your needs.

6. Turn Off the Water, Gas, Electric

Before installing any appliance, turn off the utilities related to your project, whether it’s the gas, water, or electric. Once you’re confident that your appliance is connected properly, you can turn the power source or water back on.

7. Level Up

Leveling your appliance isn’t just for convenience, it’s for function. An unlevel washing machine, for example, can leak and cause water damage. Dishwashers and refrigerators have adjustable legs to help level them even on uneven ground. Use an air-bubble level to get your appliances positioned correctly.

8. Brainstorm a Plan for Your Old Stuff

When swapping out an old appliance for a new one, it’s a good idea to have a plan in mind for the old one. If you’re having your new appliance delivered, some stores offer a takeaway service as part of the cost of the new appliance or for a fee. Your trash service might offer curbside pickup if you arrange for it ahead of time. Do your research early so you’re not stuck cramming multiple machines into the corner of your garage.

9. Know When to Ask for Help

Though DIY-ing projects can be very gratifying, there is no shame in calling in a professional—especially if there’s an issue of safety. Many appliances are in place for a long time before they’re moved, so they can mask a broken baseboard, water damage, or even a broken electrical or gas line that needs professional repair. If the installation starts to feel overwhelming, it’s okay to stop and call in the experts. A local handyperson can get you back on track.
