What is the importance of commercial HVAC construction?
A working HVAC system is essential to a commercial structure. Keeping employees comfortable makes for a better work environment, and keeping clients and visitors comfortable is just as important. So, when a new structure is being built, you want to make sure you’re choosing all the right components, making commercial HVAC construction crucial.

What is the purpose of an HVAC system in a commercial building?
As known by most, HVAC is the acronym for “Heating, Ventilation, Air Conditioning”. A commercial HVAC system will not only keep employees, clients, and visitors comfortable but also keep a conducive indoor environment. It does this by controlling the humidity and temperature as well as the air quality.
Are there different systems of commercial HVAC construction?
If you are in the process of new commercial construction, there are three common types of commercial HVAC construction systems to consider:
Split HVAC System: The way this type of commercial HVAC construction system is set up is what gives it this name. There are 5 different parts to this system:
- An indoor unit, akin to an air handler
- An outdoor unit, akin to a condenser
- A thermostat
- A filtration or humidity control system
- Ductwork that moves the conditioned air throughout the structure
Also note that within a split commercial HVAC construction system there are two different types:
- Single split: An affordable system that is ideal for small areas like a café, server room, or individual offices.
- Multi-split: This allows several indoor units to be connected to a single external unit and is ideal for larger areas like doctor offices, retail shops, and restaurants.
Some other systems to keep in mind include VAV systems and CAV systems. These are unique systems that have their own important properties.
VAV System: A Variable Air Volume system is ideal for areas where there are varying needs for cooling and heating by using a fan speed or system compressor based on the room temperature. The compressor regulates the flow of the refrigerant to keep the temperature consistent. Examples of this type of commercial HVAC construction are:
- Heat pump systems
- Heat recovery systems
CAV System: Using a compressor, this commercial HVAC construction system will operate at full capacity until the desired temperature is achieved. This system is ideal for a commercial space where the temperature remains constant for an extended time like in a manufacturing setting.
How do you calculate the right size of an HVAC system for a commercial building?
When it comes to commercial HVAC construction, size matters! The proper size will affect not just the cost, but the performance and maintenance too. So, what is the proper way to determine the right size? First, you’ll need to consider these factors.
- The difference between the desired indoor temp to the current outside temperature
- The design of the building and ceiling and wall insulation
- The relative position to the sun
- The average room size and number of people in the structure
- Specific amount and type of lighting throughout the structure
- What activities take place in the structure
Now, the process of choosing the right size of commercial HVAC construction system starts with the reminder that HVAC is measured in tons. Then determine the square footage of the space to be cooled and heated and divide that number by 500. Next, multiplying that number by 12,000 will give you the precise space cooling load.
Consider that you need 380 Btu per occupant, and 1,200 Btu in any kitchen area o the building. Adding 1000 Btu for the solar radiation coming from the windows and then dividing by 12,0000 to convert into tons. That will be the size of commercial HVAC construction needed.
How much does a commercial HVAC system cost?
There isn’t any way to provide specific costs for commercial HVAC construction, but some ideas of costs are:
- Replacement HVAC units can cost up to $10,000, or as much as $60 per square foot. The brand and size are key factors in determining the cost.
- Replacement HVAC ductwork can cost as much as $30 or more per linear foot.
In Conclusion: What is the average lifespan of a unit installed with commercial HVAC construction?
With a quality brand installed by a professional HVAC contractor, the lifespan of a commercial HVAC construction is between 15 and 20 years. Having the recommended maintenance can help you reach the 20-year life expectancy.
- The Air Filter: Just like your home’s HVAC system a commercial HVAC construction should have the air filter changed or cleaned every 30 days. This contributes to the efficiency and longevity of the system. This one step is crucial in preventing clogged coils and dirty air ducts.
- Routine maintenance: An experienced HVAC contractor that installed your commercial HVAC construction will usually offer a preventative maintenance program. This will prolong the life expectancy and keep the technician familiar with your system. In most cases, a full inspection and cleaning by an HVAC technician should be done at the start of spring and again at the start of the fall.
