Residential vs Commercial Heating and Cooling

Stevensons Air Control provides HVAC service for both residential and commercial customers. We understand the differences between residential and commercial heating and cooling. With over 20 years of experience, we work hard to ensure we meet your exact needs and standards.

So, What’s the Difference?

Size: The biggest difference is probably obvious. Commercial heating and cooling systems are much larger than residential systems. The average commercial space is larger and more open than residential spaces. This requires larger units, more units, and more energy. Larger systems are also more complicated and require more advanced maintenance.

Location: Commercial spaces often have their Air Conditioning units placed on the roof instead of the ground. This allows the placement of more units and allows them to be placed in more strategically advantageous locations.

Drainage: A/C systems produce a large amount of condensation. It is important to make sure you have a proper drain system set up. In a residential system, the drainage can usually go right out into a pan on the ground, but with a commercial system, it can become much more complicated, especially if your business uses multiple units for heating and cooling.

Number of Units: Most residential properties use a single-unit system for heating and cooling. Everything comes and goes from the same place. In a commercial property, there are often multiple units running at once. In a larger space, more units are needed to maintain the air temperature evenly across the property.

Airflow: With multiple units, there are multiple sources of airflow. Commercial buildings also tend to have fewer windows than residential properties. This adds to the challenge of keeping air moving efficiently throughout the building. The air delivery and ventilation systems are also much more intricate and require more advanced techniques and equipment than residential HVAC systems.
