How do HVAC Systems Work?

If your house is nice and cool in the summer, yet warm and toasty in the colder winter months, you have your HVAC system to thank. HVAC is an acronym which stands for Heating, Ventilation, and Air Conditioning. These systems use fresh air from outdoors to provide top quality indoor air. It isn’t just about the temperature. The V in HVAC, Ventilation, is the process of replacing or exchanging air within your home. This provides a better quality of air indoors and involves the removal of moisture, smoke, odors, heat, dust, airborne bacteria, carbon dioxide, and other gases you don’t want to be breathing. HVAC systems have plenty of moving parts in order to make this possible. It’s pretty incredible!

Thermostat: This is the piece you interact with the most, so you’re probably already familiar with it. It is usually installed on an easily-accessible wall, like right when you walk in the front door. It can be set manually and programmed to keep your home at your ideal temperature. When the ambient temperature gets too hot or cold, the thermostat triggers your HVAC system to start circulating air again.

Vents: This is another part you’re probably already familiar with. These are the outlets that help distribute heated and cooled air from the duct system into the various rooms within the house. They’re generally found on or near the ceiling because they are designed to send the air downward.

Furnace: Your furnace is the biggest part of your HVAC system, and also the hardest working. It is designed to heat air, which is then distributed to different portions of your home via ductwork or piping. Furnaces use varied heat sources, but most often heat pumps or electric resistance.

Evaporator coil: The evaporator coil is used to cool down the air when your thermostat is set to a lower temperature. This cold air is then funneled throughout your home. If your home isn’t as cool as you’d like it to be, this piece is often what needs to be repaired.

Condensing unit: This unit is found on the outside of your home and filled with refrigerant gas. When the refrigerant is cooled, the condensing unit pumps this liquid to the evaporator coil to be transformed into gas again.

Refrigerant lines: These lines carry refrigerant to the condensing unit in the form of gas. This gas is transformed to liquid form, then transferred back to the evaporator coil. The pipes are actually cool to the touch, even from the outside.

Of course, all of this assumes that your HVAC system is working correctly. If it’s not, your home isn’t as comfortable as it should be, and there may be odd smells or sounds.
