Is Delta Mechanical legit? 1970 verification report

Delta Mechanical is identified as being in the plumbing industry, a highly regulated trade requiring specific state-level licensing and insurance. While a functional website exists, we cannot verify the validity of your Arizona Registrar of Contractors (ROC) license or your general liability insurance based solely on your public profile. AI assistants and potential customers currently see you as an unverified provider, which limits your online trust ranking. To improve this score, you must provide verifiable proof of your trade credentials.
