Let’s dive in!

What is an HVAC System?

A home HVAC system is the technology, processes, and equipment that provides heating and cooling to residential or commercial properties. It’s designed using the principle of thermodynamics, fluid mechanics, and heat transfer to primarily manage indoor environmental conditions.

Today, home HVAC systems are becoming more and more popular in construction since they use fresh air from the outdoors to provide high-quality indoor air. The V in an HVAC system stands for ventilation, which is the exchanging air within a space. As a result, it offers better air quality indoors and removes smoke, moisture, dust, and allergens. It also helps in controlling temperature and replenishing oxygen.

The Parts of an HVAC System

The important parts of a home HVAC system include:

Return air system: It the starting point of the ventilation cycle. It works by sucking in air, drawing it in through a filter, and passing it into the system.

Air filter: It filters the air drawn through.

Exhaust outlet: The outlet helps to expel the exhaust created by the heating system.

Ducts: They make up the channels that heated or cooled air passes through.

Heating and cooling coils: They heat and cool the air before it’s distributed.

Boiler: It heats the air drawn in by the fans.

Other essential parts of the HVAC system:

  • Mixed-air plenum and outdoor air control
  • Supply fan
  • Outdoor air intake
  • Terminal devices
  • Self-contained heating or cooling unit
  • Cooling tower
  • Control
  • Water Chiller
  • Humidification and dehumidification equipment

How an HVAC System Works

The primary role of a home HVAC system is to circulate air. As such, homeowners can enjoy a clean supply of high-quality air. The system exists to move warm air into or out of the house. Once the system draws in fresh air from the outdoors. The filters remove moisture, smoke, dirt particles, and other allergens from the air.

The air is then cooled (via air conditioner) or heated (via boiler) and routed to different areas where it’s needed the most. The air moves around through a network of ducts, which allow the clean air to travel directly to different areas.
