How does an HVAC system work?

A HVAC system regulates indoor temperature, humidity and air quality. It consists of a thermostat for control, heating through a heat pump, cooling using an air conditioner, an air handling unit for air circulation, ducts for distribution, ventilation for fresh air, air filtration and optional humidification/dehumidification. Regular maintenance is crucial for efficiency and comfort. The primary function of a HVAC system is to move warm and cold air efficiently throughout your property.


How do you calculate HVAC requirements?

Accurate sizing ensures efficiency, comfort and energy savings. Calculating HVAC requirements involves determining the heating and cooling loads necessary for a comfortable indoor environment. Follow these steps:

  1. Measure building dimensions and orientation.
  2. Identify materials and assess insulation levels.
  3. Consider occupancy, activity, lighting and appliances.
  4. Analyse local climate and ventilation needs.
  5. Perform load calculations using software or manuals.
  6. Select appropriately sized equipment, prioritising energy efficiency.
  7. Consult Fonko’s HVAC professionals for complex projects.
