HVAC inspectors are essential to maintaining efficient and safe heating, ventilation, and air conditioning (HVAC) systems in residential and commercial buildings. Poorly maintained HVAC systems can lead to a variety of problems, including high energy costs, poor air quality, and system failures. By ensuring that HVAC systems meet industry standards and regulations, HVAC inspectors can help protect occupants from health hazards, reduce energy costs, and extend the life of the system.

HVAC inspectors check the condition of the system components, including the furnace, air conditioner, ventilation ducts, and electrical wiring. They may also review maintenance records and ensure that safety protocols are in place. The results of the inspection are documented in a report that details any issues or concerns regarding the system and provides recommendations for correcting them.

Taking these steps can help ensure the safety and efficiency of HVAC systems and save money in the long run.
