Your commercial HVAC system’s components allow it to operate correctly. When the parts of your HVAC system work well together, they heat and cool your facility efficiently. But which components are most critical for HVAC operations and indoor air quality solutions? Let’s look at the most critical components to see how they affect indoor air ventilation and quality.
A commercial HVAC system has several parts that drive its heating, cooling, and ventilating processes, including:
- Air conditioner: The air conditioner is, of course, a core component. After all, it’s the AC in the acronym HVAC. It dehumidifies and removes heat from the air. It’s a big part of the system’s cooling process, but it doesn’t cool the building directly.
- Compressor: The compressor starts the system’s cooling cycle and allows you to control your facility’s temperature. It compresses the refrigerant, raising its temperature before it moves on to the condenser.
- Condenser coil: The condenser coil receives gas refrigerant and turns it into liquid. It also removes hot air from your facility and redistributes it outside.
- Thermal expansion valve: This valve expands the refrigerant from a liquid to a gas or vapor. Then the refrigerant flows into the air handler’s evaporator coil.
- Air handler: The air handler circulates cool air throughout your facility. It also contains the evaporator coil and blower. The evaporator coil stores the refrigerant it receives from the compressor and condenser, while the blower moves over the coil to remove heat from the air.
- Chiller: The chiller cools down the liquid that runs through an HVAC system. Some HVAC systems use water-cooled chillers, while others use air-cooled chillers.
- Terminal units: These units vary in size, but they usually contain a coil, blower, and air filter. A terminal unit often controls a single room’s temperature, and is sometimes located on the roof.
- Ductwork: The duct system carries the air produced by the HVAC system to different parts of your facility. It works best if it’s clear of dust, dirt, and bacteria.

If you want your facility to have good IAQ, you need to pay attention to your ductwork. Your duct system is critical, because once the air leaves your main HVAC units, it travels through your ducts. While it’s there, the air picks up everything in them, including dirt, dust, and bacteria, distributing these contaminants throughout your facility. As a result, your facility’s occupants breathe in dirty air that could make them sick. Regular duct maintenance keeps your air clean and healthy.
Routine HVAC maintenance ensures your system’s components operate correctly throughout the year. For example, evaporator coils need regular maintenance because they store a large amount of refrigerant. Other components, like the blower motor, need regular checks to make sure they haven’t broken down or developed problems over time.
