The Basics of HVAC System

Almost every home or office has an HVAC (heating, ventilation, and air conditioning) system installed. This system is the one responsible for controlling the cooling and heating in our homes. We rely on our HVAC systems to provide us with a comfortable environment during scorching summer days or freezing winter nights.

An HVAC system, however, does more than just control your home’s temperature. It also controls the moisture and filtration of the air, maintains the balance of oxygen and carbon dioxide levels in an air-conditioned space, and finally, controls the movement of the air in your space.

Essential HVAC components

An HVAC system is a combination of parts working together to keep your unit running smoothly. Understanding the functionality and purpose of these various components can help you care for your system.

1. Refrigerant

The refrigerant absorbs the heat inside your home and replaces it with cool air. During winter, the refrigerant absorbs the heat from the outside and transports it inside your home. Without the AC refrigerant, no air conditioning can take place.

2. Evaporator coils

Evaporator coils are located inside the indoor unit, or the evaporator. The refrigerant flows through these coils and absorbs heat from the indoor air passing over it. After the removal of heat, cool air is left to circulate inside your house.

3. Compressor

The compressor is a part of the outdoor unit of your HVAC. It compresses the refrigerant and converts it into gas. This step prepares the refrigerant to exhaust the heat picked up by the condenser.

4. Condenser

Also an outdoor unit, a condenser is responsible for dissipating the absorbed heat outside during the cooling process. As the refrigerant enters the condenser, the coils facilitate the transfer of heat energy from the refrigerant to the outside air.

5. Ductwork

Ductworks are a series of passageways that transport the air to every single room of your home. They are the veins of your HVAC system.

6. Air vents

From your ducts, the air enters your room through the vents. These are the openings in your house with rectangular covers, positioned either on the ceilings, floors, or walls.

7. Blower motor

The blower motor pumps the air to be delivered throughout your house. It comes into action when the air reaches the temperature as dictated by the thermostat.

Benefits of a well-maintained HVAC system

Preventative maintenance of your HVAC unit can correct minor issues that will otherwise lead to serious problems when not addressed. By keeping your unit well-maintained, you won’t have to deal with the hassles or unnecessary repairs and costs, and you can fully enjoy the benefits of having an HVAC system.

There are multiple benefits to keeping your HVAC system in top condition:

AC Maintenance

1. Lower utility bills

Maintaining your HVAC units will help reduce your utility bills. A well-maintained HVAC unit will operate efficiently, spending less money on electricity costs. Regular maintenance of HVAC units is also important to prevent the need for major repairs.

2. Healthy air quality

A well-maintained HVAC unit will keep your home cozy and fresh, and it will limit problems with air quality. An unmaintained HVAC unit is a magnet for dirt, bacteria, molds, and many other pathogens, which may result in respiratory issues for those living in the home.

3. Increased lifespan for your HVAC unit

Periodically maintaining your HVAC unit will extend its service life. A brand new HVAC system will cost you thousands of dollars, so it makes more sense to want to keep your unit operating in tip-top shape for many years.
