A good contractor is hard to find. Let us help.

Take the guesswork out of selecting your contractor. Easily find a licensed contractor or natural gas appliance dealer from our listing of certified experts. We encourage customers who are facing an unexpected repair, planning a home improvement project, or considering additional weatherization measures to use care and due diligence before hiring contractors. Take a moment to select contractors that are properly licensed for the type of work you need.

Verify contractor's license information

Obtain the contractor's license number and check them out with the state contractor's board:


877-MY AZROC (877-692-9762)




Southern NV 702-486-1100
Northern NV 775-688-1141


Each state has different requirements for contractors to do business, including types of insurance and licenses needed. Before you call a contractor, have an idea of what your needs are so potential contractors will have a better understanding and can provide you with an accurate quote.

Check the contractor’s record with the Better Business Bureau

The BBB Standards for Trust are a comprehensive set of best practices for how businesses should treat the public in a fair and honest manner. Visit them at .

Ask Around!

Your family, friends and neighbors are valuable resources for information on specific contractors. Get their feedback from their own experiences, as it may help you with your decision.

Get Written, Itemized Estimates

Receive at least three bids that include costs for labor, parts, equipment, and more as well as warranty information. Keep in mind, cheaper is not always better. If the lower priced appliance is not as efficient as another make and model, your energy costs may be higher. Contractors are required to include their license number on all invoices, vehicles and advertising materials.

Keep Records

Keep files of all documents related to your project including contracts and receipts. Get a written contract and do not sign anything until you completely understand the terms. Do not pay in cash and only make the final payment when you are satisfied.
