Choosing an HVAC Contractor

The Air Conditioning Contractors of America (ACCA) suggests that consumers consider the following items when choosing a contractor.

Be sure that:

• Your contractor is properly licensed. In Maryland, this means having a Master's "HVACR" license, as well as an electrical and/or a gas fitter's license. Your contractor's technicians should all carry an apprentice or journeyman's HVACR license and be certified to handle refrigerant.
  
• Your contractor carries adequate business and workers compensation insurance. In Howard County, a performance bond is not a requirement.
  
• Your contractor has adequate technical and practical experience. Technicians who are "NATE Certified" have passed rigorous exams by the North American Technician Alliance to certify that they have the necessary mechanical knowledge and expertise to service heating and cooling systems.
  
• Your contractor provides you with a written contract.
  
• Your contractor is willing and able to provide warranty service.
  
• You examine factors such as references, reliability and quality of service in addition to price.
