Do you want to explore the working of HVAC systems? If yes, then here this guide can help you understand more about the HVAC system and how it works and hvac consultant. In general, HVAC (Heating, Ventilation, and Air Conditioning) systems will keep your home warmer in the winter and cool in the summer.

You will never feel any complexity due to the outside temperature after installing the quality system. The work is very effective. Proceed further and learn more.

Generally, most HVAC systems work similarly. But there are some variations based on the type of the HVAC system that you have installed in your office or home.

Before knowing the working of this system, you must thoroughly have the knowledge about its parts. The Heating, Ventilation, and Air Conditioning system is effectively made up of core parts along with certain features that are added in certain models.

What are the core components of an HVAC system?

Before knowing the working of this system, you must thoroughly have the knowledge about its parts. Check out below to explore the core components of HVAC system:

Using natural gas or oil, the furnace will work. There will be a heat exchanger on the furnace that can heat the air effectively to perfectly set the temperature. The furnace will be in the home’s basement, attic or in the closet. It is responsible to generate heat when the system keeps the surrounding hot instead of cool.

AC is the part of the HVAC system that is responsible for keeping the environment cool. It has the ability to cool the air most effectively. The compressor will be located outside since it is the outdoor unit. It uses liquid refrigerant and electricity to cool the temperature. It pushes cool air inside your home and sends hot air outside.

Ductwork is the group of ducts installed throughout your home. A duct is the tube or pipe that conducts the substance throughout the surrounding area where it is installed.

During HVAC, the ductwork can produce the air, either cold or hot air according to the thermostat settings that will be into the vents around the home. The registers or vents in the home’s ceiling or floor are the opening into the duct and it can deliver air into each room very effectively.

You must ensure that vents never get blocked to have a perfect airflow into each room. When cold air sinks and hot air rises, you need to adjust the vents from each room to grab the perfect result.

If you want to start the ventilation cycle, then sure air return plays the major role. It can draw the air into your room, pass it through the filter and finally make it reach the main system effectively.

Air filter is the 2nd major part of the HVAC system since the outdoor air is completely drawn into it. Then it will be thoroughly cleaned before getting into the main system. The filter has a great impact on indoor air quality. Hence choose the perfect size according to your space and make a huge difference.

In the exhaust outlet, the exhaust from the heating system will leave the home. The chimney flue is one of the most effective exhaust outlets.

The electrical elements or parts of the HVAC system are somewhat complex. But when you find any problem with the system, check out the breaker box and find whether the breaker is tripped.

Outdoor unit is also one of the components of the HVAC system. Thermostat will send signals between the indoor & outdoor to execute its working. It will hold the fan that is providing the air flow to the surrounding. For more efficiency, ensure there is no debris & vegetation in the unit.

You will find the compressor inside the outdoor unit. It is the first step of the air conditioning system. It will completely compress the gas into the liquid and let them travel through the pipes and pass to the air conditioning system.

There will be a condenser coil inside the outdoor unit. The main task of the condenser is to remove the heat from the surrounding.

Evaporator coil is also a part of the outdoor unit that can cool the air effectively with the help of refrigerant. Go through the level of coil & refrigerant annually or when you notice that your system is getting frozen.

Blower is also one of the components of the HVAC system that can draw in the warm air via the essential part of the unit.

A thermostat is the brain of the whole HVAC system that will be inside your home. It is used to control the temperature and mode. During the heating mode, it can heat up the home when it reaches a certain level of temperature. After achieving the set temperature, it will automatically turn off. In the cooling mode, it will completely cool down the home after reaching the threshold.

Working of HVAC system:

A HVAC system can help you maintain a right temperature in your home and can also be helpful during ventilation. The thermostat will start the system. When the temperature in the home is cooler or warmer than the set temperature, then your system will turn on & work until it reaches the set temperature.

The heating part warms the air & the blower perfectly blows it into the duct system in the forced air system to distribute the air throughout the home. When the air conditioner is running, the outdoor unit can pull the warm air in and pass it over the coil and then the refrigerant cools it & blows the cold air around the home.

Conclusion:

Change the filter regularly with the help of hvac consultant to keep your HVAC system under good working condition. It can increase its lifespan.
