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:

Safety

• 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

Efficiency

• 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.
