It’s important to ask an electrician a few questions before you commit to hiring them so you can make an informed decision as a consumer. If you’re getting estimates or considering hiring an electrician, ask them these questions:

• Are you a full-time electrician?

• Are you bonded, licensed, and insured?

• What level of experience do you have as an electrician?

• Can you please share three references?

• Do you do residential or commercial electrical work?

• What kinds of electrical work are you most familiar with?

• Will any subcontractors be performing the work?

• Are permits and inspections required?

• Who is responsible for obtaining permits and inspections?

• What is your schedule?

• Do you offer a guarantee or warranty on your work?

• Will you sign a do-not-exceed clause to keep the job within the budget?

240V is the standard for more demanding appliances in the United States, whereas 220V is more common elsewhere. The voltage isn’t very different in any practical sense. The United States is a newer country compared to many other regions in the world with a faster adoption of new electrical needs. Appliances in the United States are often bigger than other parts of the world.

It wouldn’t be abnormal to view all wiring as simply wiring, but wiring has different gauges and can handle different loads. When you’re wiring for 240V, you need wire that is rated at least 240V, but honestly it’s better to spend a little more and just buy 300V wiring. This ensures a margin of safety in case the wiring gets overloaded.

Yes, dehumidifiers use a lot of electricity. However, proper humidity also means your home’s temperature remains more stable, thus lowering heating and air conditioning bills. The good news is you shouldn’t need to use a dehumidifier more than a few months per year, so the energy costs won’t be as noticeable as other larger appliances.
