Understanding the Parts of Your HVAC System

As an HVAC installation expert, we recommend studying and learning about your unit because this will allow you to make better and more informed decisions regarding its life cycle. Your heating and cooling equipment perform the essential task of making your home’s interior comfortable all year round. Understanding the key roles your system plays and how it operates will allow you to get the most out of it.

Understanding HVAC System Roles

Below we explain more on how to make the most of your HVAC system.

H Stands for Heating in HVAC

The heating component of your HVAC system is responsible for providing a warm climate for your interior during the cooler months. Currently, the most popular kind of heating system is the forced air system; but ,there are other systems as well, such as geothermal heating and radiant heat systems. What these systems have in common is that heat is created at a central source. They differ in the ways that the heat is distributed throughout the home.

A forced air system, for example, uses a furnace to heat the air and then distributes it throughout the home via in-room vents and ductwork. Geothermal heating, on the other hand, uses the constant temperature of the ground created by the sun’s rays to create heat for your house via a heat exchanger. Radiant heating systems use a boiler or heating stoves to distribute heat through the home via a network of hot water tubing or electric heating coils installed in the ceiling or the floor.

V Stands for Ventilation in HVAC

The HVAC system has an important role in maintaining good indoor air quality within your home. The ventilation provided by the system prevents air stagnation, helps circulate and purify air, removes unwanted smells, and controls moisture levels. Ventilation can be done naturally, mechanically, or through a combination of the two. You can use devices such as air purifiers, air cleaners, dehumidifiers, and humidifiers to keep your indoor air clean and free of pollutants.

AC Stands for Air Conditioning in HVAC

The cooling component of your HVAC system is responsible for providing a cool climate for your interior during the warmer months. There are several different kinds of air conditioning units with each type having its own pros and cons. However, the process used by central air systems, portable A/C units, window A/C units, and split A/C units are all similar.

The A/C system circulates refrigerant that changes from gas to liquid as it gathers and removes heat from your house. It passes warm vapor refrigerant through the compressor where it changes into hot refrigerant vapor and then passes through the condenser. In the condenser, the hot vapor is cooled as air from the condenser fan moves over finned coils and becomes hot liquid.

The hot liquid moves through the expansion valve that creates a low-pressure, cool liquid mist that runs through the evaporator and evaporates. The evaporating cool liquid mist absorbs heat from your home’s inside air and returns it to the compressor, starting the process again. The A/C pushes the absorbed heat outside your home, resulting in a cooler interior.
