The typical HVAC system has several key components:

• A furnace or heat pump for heating
• An air conditioner or heat pump for cooling
• Ductwork for distributing air
• A thermostat for temperature control
• Air filters for improving indoor air quality

HVAC systems circulate air throughout your home, heating or cooling it as needed while filtering out contaminants.

• In cooling mode, refrigerant absorbs heat from indoor air and releases it outdoors.
• In heating mode, heat is absorbed from outdoor air and transferred indoors.
• Fuel-burning furnaces heat air through combustion, distributing it via ducts.

While some minor issues can be resolved on your own, certain problems require professional expertise. Call an HVAC professional if you notice: – Persistent error codes – Unusual noises or odors – Significant changes in energy bills – Uneven heating or cooling – Frequent system cycling on and off.

An HVAC system stands for Heating, Ventilation, and Air Conditioning. It regulates temperature and improves air quality using components like furnaces, air conditioners, and ventilation systems.
