FAQ
What does HVAC stand for and what systems are included?
HVAC stands for Heating, Ventilation, and Air Conditioning. It refers to the technology and systems used to regulate indoor temperature, humidity, and air quality in residential, commercial, and industrial buildings. A standard HVAC setup may include components such as air conditioners, heaters, ventilation ducts, air purifiers, exhaust fans, humidifiers, dehumidifiers, and smart control systems. More advanced systems may also include chilled water systems, VRF (Variable Refrigerant Flow) units, and cooling towers. The goal of HVAC is to create a comfortable, safe, and energy-efficient indoor environment, no matter the external weather conditions.
What is the difference between HVAC and air conditioning?
Air conditioning is just one part of a complete HVAC system. While air conditioning focuses specifically on cooling the air, HVAC includes heating and ventilation as well. HVAC systems are designed to regulate not only temperature but also airflow, humidity, and indoor air quality. For example, an HVAC setup may include an air conditioner for cooling, a furnace or heat pump for heating, and a ventilation system to circulate fresh air and remove stale air or pollutants. In commercial and industrial settings, HVAC systems often incorporate more complex controls and equipment to maintain comfort, safety, and energy efficiency across multiple zones.
How do I know what size HVAC system I need?
Determining the right size HVAC system requires a detailed assessment of the building’s size, layout, insulation, number of occupants, and climate conditions. Oversized systems can lead to short cycling, higher energy bills, and inconsistent temperatures, while undersized systems may struggle to maintain comfort and wear out more quickly. Professionals use calculations such as Manual J (for residential) or Manual N (for commercial) load assessments to determine the appropriate capacity, usually measured in kilowatts (kW) or BTUs. Factors like ceiling height, window placement, and internal heat loads from equipment or lighting also play a role. For the most accurate sizing and system performance, a professional site evaluation is recommended.
