HVAC System and how they Operate
What are HVAC Systems?
HVAC stands for Heating, Ventilation, and Air Conditioning. This acronym covers just about everything used to keep your home comfortable. HVAC Systems provides heating and cooling to commercial and residential buildings. The “Ventilation” in HVAC denotes the process of exchanging or replacing air within a room. The exchange of air, in addition to temperature control and oxygen replenishment, involves the elimination of heat, moisture, dust, airborne bacteria, carbon-dioxide, and other gaseous substances. This process generates quality indoor air.
The HVAC system is becoming very popular especially in new building projects. Over 85% of the recent projects completed by Reef Air Conditioning consist of HVAC Systems. HVAC Systems exist in residential buildings, commercial buildings and even submarines. It uses the air from the surrounding environment to provide high quality indoor air and thermal comfort.
Three Major Sections of HVAC Systems
As earlier said, HVAC stands for heating, ventilation, and air conditioning. These are the three major sections of the HVAC systems.
Heating: The heating section is called the boiler or furnace. It consists of a pipe array for the heat carrying fluid. If it is operating with a forced air system, a ductwork is utilized.
Ventilation: The ventilation section consist of either natural or forced ventilation. If it is forced ventilation, it is as well commonly used for air cleansing.
Air Conditioning: The main function of this section of HVAC systems is to remove the heat indoors.
How do HVAC Systems Operate?
HVAC systems are one of the most complicated and extensive heating and air conditioning systems. It consists of nine (9) basic components. Learn how an HVAC works by reading about the different components of HVAC systems.
The air return is the part of the HVAC systems where the ventilation cycle starts. The air return takes in air, through a filter, and then passes it into the main heating and air conditioning system.
Hint: Ensure the air return is dusted regularly to prevent dust and debris from building up on the filters of the HVAC system.
The filter is a part of the air return through which air is drawn.
Hint: Ensure your filters are changed regularly to keep HVAC systems in an optimum working condition.
This is the component through which the exhaust generated by the heating system is expelled.
Hint: Ensure your chimney vent stack or flue is checked annually and tuned up if necessary.
The ducts are the channels through which the cooled or heated air pass through.
Hint: Always keep the ducts of HVAC systems cleaned to keep it in an optimum working condition. Do this every two to five years.
This component of HVAC systems is complicated and trickier. Most times, this is where problems originate first.
Hint: Check for dead batteries in the thermostat or a tripped breaker if there is a problem.
The outdoor unit encloses the fan that provides the air flow. It is that part of the HVAC system that you see and imagine when someone mentions an HVAC unit.
Hint: Keep the HVAC unit free of vegetation and debris to prevent them sticking in the fan of the HVAC unit.
The compressor is part of the HVAC’s outdoor unit. The compressor converts the gaseous refrigerant to liquid and passes it to the coils.
Hint: Check your compressor if the HVAC unit is malfunctioning. The compressor is often the cause of several failures in HVAC systems.
The coils, with the aid of the refrigerant cool the air as it the air passes through the coils.
Hint: Ensure you check the coils of the HVAC unit annually. Check the levels of the HVAC’s filter or/and refrigerant if the coils are frozen.
The blower takes in warm air through the main part of the HVAC unit.
Hint: The durability of the HVAC unit can be affected by the efficiency of the airflow.
HVAC and Air conditioning, The Difference.
AC is usually used to refer to any type of cooling or heating equipment in our home. The difference between HVAC and Air Conditioning is a question that is often asked by most people. Air Conditioning (AC) is the last part of the HVAC acronym. Just imagine AC as a part of the jigsaw puzzle piece and HVAC as the entire Jigsaw puzzle.

What’s the duration of HVAC Systems?
Having known what HVAC systems consist of, you might be curious to know how long an HVAC unit last. The durability of an HVAC unit depends on its type and ability to follow the recommended yearly maintenance required. With the regular yearly maintenance recommended, it can last for several years.
Now that you understand exactly what an HVAC system consists of, you’re probably wondering how long a new one will last you. That really depends on the state of the equipment. But, if you keep up with your recommended annual maintenance your equipment will last you for years and years to come.
