HVAC stands for heating, ventilation, and air conditioning, and it refers to the systems that are used to regulate indoor temperature and air quality. Educating yourself on the various components of your HVAC system can help you identify problems when they arise and feel more prepared when a technician visits your home to perform maintenance or repairs.
Here are the basics of how an HVAC system works:
- Heating: The heating component of the HVAC system is responsible for warming up the air in a building. Heating is usually done with a furnace or heat pump that heats air or water, which is then distributed through the building via ductwork or pipes.
- Ventilation: The ventilation component of the HVAC system is responsible for moving air in and out of the building. Ventilation helps regulate the amount of fresh air being brought in and the amount of stale air expelled. It also helps to remove pollutants, such as dust and allergens, from the air.
- Air Conditioning: The air conditioning component of the HVAC system is responsible for cooling down the air in a building. This is usually done with a compressor that circulates the refrigerant through a series of coils. The refrigerant absorbs heat from the indoor air, which is then released outside. The cool air is then distributed through the building via ductwork.
- Thermostat: The thermostat is the control center of the HVAC system. It is used to set the temperature that the system should maintain, and it turns the heating and cooling components on and off as needed to maintain the desired temperature.
Overall, an HVAC system is designed to provide a comfortable and healthy indoor environment by regulating temperature, air quality, and humidity. Being familiar with the components is helpful as a homeowner, but remember that scheduling regular maintenance, inspections, and repairs can extend the life of your HVAC system and keep you comfortable all year.
