Take Measurements
How large a set can you accommodate? Front load washer and dryers tend to be larger than conventional ones so make sure you take accurate measurements (height, depth, and width) to ensure the ones you want fit.

Compare Brands
Make a visit to all your local appliance stores to find out what's available on the market and compare brands and features. Narrow down your options by choosing what appeals to you.

Consumer Reviews
Do your homework online and research consumer reviews of the brands and models that you like. Find out what those who have actually used them are saying – what they like and more importantly what they dislike about the product.

Select the Right Kind
Consider how you will be using your washer and dryer: how often will you use them and for what kinds of laundry? Is it just you and your spouse or an entire family that you have to do laundry for? Do you dry most of your clothes or do you often have heavily soiled loads? Take this all into consideration assessing different features including temperature settings, water level settings, energy efficiency, and load capacity.

Compare Shop
Once you've narrowed down your choices, do some comparison shopping to find the best prices (or to figure out which models are the best value). Make sure you establish your budget prior to shopping.

Purchase
Decide where to purchase based not only on price but delivery and whether or not you want them to haul off your old washer and dryer.
