A mechanical permit is required for installing or modifying heating, ventilating and air conditioning (HVAC) systems. Homeowners must be capable of ensuring the work will be done in accordance with applicable safety regulations.
If you have no previous knowledge or experience with HVAC systems, your best option is to hire a licensed contractor who is eligible to receive permits. Work completed by inexperienced individuals often requires extensive corrections to bring the installation up to code, and may create a serious hazard.
