A Handbook for Homeowners: Maximizing Comfort and Minimizing Environmental Impact

It is essential to know the basics of HVAC systems, before you dive into more advanced tips. These systems are the backbone of home comfort, regulating temperature and air quality throughout the year.

HVAC systems usually consist of a few key components.

• Heat pump or furnace for heating
• Air conditioners or heat pumps for cooling
• Ductwork for air circulation
• Thermostats for temperature control
• Air filters for improving airquality

These systems are easy 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.

HVAC systems come in different varieties, each with their own advantages.

• Many homes have central air systems that provide both heating and cooling via a network of ducts.
• Heat pumps can heat and cool making them a versatile option for climates with moderate temperatures.
• Ductless mini-splits are excellent for homes without existing ductwork or for adding temperature control to 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 these basics can help you communicate better with HVAC professionals, and make more informed decisions about your home heating and cooling requirements.
