How Important is the Design of an HVAC System?

Heating, ventilation, and air conditioning (HVAC) systems are essential for maintaining appropriate temperatures in interior spaces. The design of those systems can have a major impact on how effective they are. That’s why the importance of thoughtful design cannot be overstated.  Here’s what to keep in mind

System Type

There are several different types of HVAC systems, each with unique benefits (and drawbacks). The best HVAC design will take into account all relevant factors before choosing the right HVAC system type.

One of the most common types of HVAC systems is the traditional split system. This system is split into two units – a cooling one and a heating one.

In cases where traditional duct systems aren’t workable, the HVAC design may incorporate a ductless split system. These systems have individual units that all have a separate thermostat to control them. Ductless split systems are ideal for buildings such as hotels and apartment complexes.

Other HVAC systems include geothermal systems, packaged systems, and hybrid split systems. The HVAC designers will need to choose which of these options best suits the building the system will be placed in and the needs of the owners.


Deciding on the size of the HVAC system is one of the biggest choices to make in a building’s HVAC design. This is one case where bigger is not always better. The HVAC system needs to be a “goldilocks” size, not too big or too small.

An HVAC system that is too small will run constantly trying to get the space to the right temperature but never getting there. This means excess fuel use and extra costs.

On the other hand, an HVAC system that’s too large will heat and cool the space too quickly. This causes the system to cycle constantly on and off, resulting in a high level of wear and tear on the system. In the long run, an oversized HVAC system will have a shorter lifespan.

Code Compliance

Without careful design, an HVAC system can violate local, state, or federal building codes. Systems that aren’t up to code could cost the building owners in significant fines or even trouble selling their property down the line.
