What is Checked During Safety and Efficiency Inspections for HVAC?

Here is a list of things that are assessed during a safety and efficiency inspection for HVAC units. Note that each service provider may have differences in their inspection checklists, so simply treat this as your baseline guide:


  • Detecting for gas leaks in an HVAC system that uses dual-fuel or gas furnace
  • Checking for ambient carbon monoxide around the house and around the HVAC unit itself
  • Detecting any refrigerant leaks
  • Looking at the heat exchanger through a combustion analyzer
  • Any combustible items placed within 10 feet near the HVAC unit moved to a farther place
  • Checking for faulty electrical wirings such as frayed or exposed cords on the unit
  • Tightening connections between electrical wirings


  • Checking the overall cleanliness of the entire HVAC unit inside and outside
  • Assessing the cleanliness of the blower assembly
  • Checking all vents or flues for any damage, dirt, and dust buildup
  • Ensuring that all vents or flues are properly vented to the outdoors
  • Inspecting the fan motor, heat pump compressor amps, blower capacitor, and other components of the HVAC system
  • Looking into the pipes and ductwork condition
  • Identifying any HVAC appliances that are sized improperly

Most providers also offer on-the-spot cleaning as part of their safety & efficiency inspections for HVAC. Your technician may require added appointments for larger issues like duct cleaning or parts replacement.
