Zamm Heating & Cooling

Ohio does not require contractors to be licensed to perform residential construction. However, Ohio does require a contractor to be licensed for commercial construction.

Zamm Heating & Cooling Llc currently holds license HV.49610 (Hvac Contractor), which was Active when we last checked.

Commercial contractors must pass a trade exam and prove continuous trade experience in order to become licensed in Ohio. Continuing education is required to renew all commercial contracting licenses.

Commercial contractors are required to carry a general liability insurance policy. Although there is no requirement for residential construction, it is always a good idea to only hire contractors with both general liability and workers' compensation insurance. Request a current insurance certificate for both general liability and workers' compensation before any works starts.

Commercially licensed contractors in Ohio must provide tax records for the previous 5 years to be eligible for a license.

The BuildZoom score is based on a number of factors including the contractor's license status, insurance status, verified work history, standing with local consumer interest groups, verified reviews from other BuildZoom users and self-reported feedback from the contractor.
