Step 1: Focus on Quality Installation. How well your Heating, Ventilating, and Air Conditioning (HVAC) system performs, and how much it costs to operate, depend in part on the proper installation of the system. Improper HVAC installation will cost more – using more electricity, running up your bill, and making your air conditioning work harder, which can shorten equipment life. Common installation problems such as low air flow, improper charge or duct leakage can reduce the efficiency and capacity of your air conditioner.

Step 2: Hire a licensed contractor who has knowledge of, and complies with, local codes, and ordinances. Licensed contractors have a minimum of 4 full years, are required to have a contractors’ bond, and are regulated by the Contractors State License Board. Installers who perform contracting work without having a

license have avoided these quality assurance requirements and, in addition, may be in violation of the law.

Step 3: Schedule a Building Inspection if necessary. When installing a new HVAC system, or changing out an old one, the installation of the equipment may be inspected by a Building Inspector who will perform a quality assurance check ensuring the system is installed to comply with all applicable State, and County or City codes.
