The maintenance of HVAC systems is closely related to microclimate conditions. It
guarantees heating, cooling, filtered outdoor air, humidity and temperature control for the
occupants. The main aim of this Bachelor’s thesis is to research how a poorly maintained
HVAC system can affect indoor climate.
The literature review will reveal what determines good indoor air quality and its relation to a
system’s maintenance. The main system maintenance steps and every six months
schedules are introduced. How unattended systems can harm human health and how fast
bacteria and fungi can grow in the systems are examined.
The results will show the main design mistakes that affect air distribution, movement,
controls, equipment, and hydronic performance. Without avoiding design mistakes,
systems require more maintenance, damage air quality, and lose effectiveness.
Unfortunately, the mistakes are difficult to detect in the following construction steps, and
they can lead to partial system failure and poor human well-being
