Gas Leak Inspection & Certification in Phoenix
HQ certifies your natural gas system with a written compliance letter accepted by Maricopa County, municipalities, and health departments. Homes and businesses, not RV or propane.
Licensed Inspection, Written Certification
When a county inspector, city official, or health department asks for proof that your gas system is safe and compliant, you need more than a verbal assurance. HQ Plumbing & Air performs a thorough inspection and pressure test of your natural gas lines, then issues a written certification letter confirming the system is leak-free and meets code requirements.
Our certification is accepted by Maricopa County, Phoenix and surrounding municipalities, and local health code authorities. We work with homeowners, landlords, restaurants, and commercial property owners throughout the Phoenix metro area.
Note: We inspect and certify natural gas systems only. We do not service RV propane tanks, portable propane equipment, or LP systems.
