The Science of Sustainable Heating and Cooling

Before we dive into tips for experts, it is important to gain a basic knowledge of heating, ventilating, and air-conditioning (HVAC). These systems provide the foundation for your home's comfort by regulating the temperature and air throughout the entire year.

HVAC systems consist of several main components.

• Heat pumps or furnaces for heating
• Air conditioners or heat pumps for cooling
• Ductwork for air distribution
• Thermostats for temperature control
• Air filters improve air quality

These systems are relatively simple to use. In heating mode, air is warmed by the furnace or heat pump and then distributed through the ductwork. For cooling, the process is reversed, with the air conditioner or heat pump removing heat from the indoor air and expelling it outside.

There are several types of HVAC systems available, each with its own advantages:

• Many homes use central air systems to provide heating and cooling. These systems utilize a network ducts.
• Heat pumps are versatile and can be used in both hot and cold climates.
• These mini-splits work well in homes that don't have existing ductwork. They can also be used to regulate the temperature of specific rooms.
• Radiant heating systems, often installed in floors, provide efficient and comfortable warmth.
• Forced air systems use a furnace to heat air and distribute it through ducts.

Understanding the basics will allow you to communicate more effectively with HVAC experts and make informed decisions regarding your home's heating & cooling needs.
