Finding Duct Leaks

An HVAC Inspection: What's Checked And Why It Matters

An HVAC (heating, ventilation, and air conditioning) system is an essential component of any home or business. Regular HVAC inspections are important for maintaining the performance and efficiency of the system. Here's a breakdown of what's checked during an HVAC inspection and why it matters.


One of the first things checked during an HVAC inspection is the air filter. The filter helps to trap dust, dirt, and other particles that can affect indoor air quality and the performance of the system. If the filter is dirty or clogged, it can reduce airflow and make the system work harder.


The thermostat is another important component of the HVAC system that is checked during an inspection. The thermostat controls the temperature and operation of the system, and it needs to be calibrated correctly to ensure accurate temperature readings and efficient operation. A faulty thermostat can lead to uneven temperatures, poor performance, and higher energy bills.

Electrical Connections

The electrical connections in the HVAC system are also checked during an inspection. Loose or corroded connections can cause electrical problems, such as shorts or sparks, which can be a safety hazard. Additionally, poor electrical connections can affect the performance of the system, leading to higher energy bills and reduced efficiency.

Refrigerant Levels

For air conditioning systems, the refrigerant levels are checked during an inspection. Low refrigerant levels can cause the system to work harder, increasing wear, causing premature failure, and using more energy.

Additionally, low refrigerant levels can affect the cooling capacity of the system, making it less effective at keeping indoor temperatures comfortable.


The ductwork is also checked during an HVAC inspection. The ductwork is responsible for distributing heated or cooled air throughout the building, and it needs to be properly sealed and insulated to ensure efficient operation. Leaky or poorly insulated ductwork can lead to energy loss, higher energy bills, and reduced comfort levels.

Blower and Fan Motors

The blower and fan motors in an HVAC system are responsible for circulating air throughout the system and the building. During an inspection, the technician will check these motors for signs of wear and tear, such as loose or corroded connections, or worn-out bearings. If these motors are not functioning properly, it can affect the performance of the system and lead to higher energy bills.

Evaporator and Condenser Coils

The evaporator and condenser coils in an HVAC system are responsible for transferring heat between indoor and outdoor environments. During an inspection, the technician will check these coils for signs of wear and tear, such as corrosion or damage. For more information on HVAC inspections, contact a professional near you.
