My home warranty company assigned this vendor to repair our failing dishwasher. I called the home warranty company to ask for J & H's license number since I could not find it by searching on the Arizona Registrar of Contractor's website. The home warranty company asked me to call J & H directly and said they were required by law to provide it. I called J & H and left a message to call. Melissa returned my call. I said "before you come out to the house I'd let to get your licensing information". She responded, "Why do you want it?" I said, "Because I asked". She refused the licensing information. I called the home warranty company and told them that because there is no license with the Arizona Registrar of Contractors under the name J & H Microwave or J & H Appliances and that because the owner (I presume) refused to provide it please cancel the work order and provide a fully licensed (in good standing), insured, bonded contractor. They were happy to comply. Caveat Emptor: Don't do business with businesses who are not licensed or who will not provide their license information.
