Knowing Your Heating and Cooling Systems: Its Various Parts and Components

Heating and cooling systems commonly referred to as HVAC or heating, ventilation and cooling systems are used for both commercial and residential purposes. From private property to submarines, HVAC systems are used everywhere for making the indoor environment comfortable. These systems are based on a mechanism that draws air from the outside environment and provides purified high-quality air indoors.

The ventilation feature in these systems typically works by exchanging or replacing the air within an enclosed space, thereby enhancing the quality of the indoor air by removing excess moisture, dust, bacteria, smoke, carbon-dioxide and other gases. Apart from temperature control, an HVAC system also helps in replenishing oxygen level of the indoor air.

Opting for a heating and cooling system is a long-term investment, however it is quite substantial. Considering the fact that the average life of a central air conditioning system is more than fifteen years, making an informed decision is vital, as it is an equipment that cannot be changed very easily. Also, the factor of monthly operating expense related to the energy efficiency of the system needs to be considered seriously.

The ventilation highlight in these frameworks ordinarily works by trading or supplanting the air inside an encased space, in this way improving the nature of the indoor air by eliminating overabundance dampness, dust, microscopic organisms, smoke, carbon-dioxide and different gases. Aside from temperature control, an HVAC framework likewise helps in renewing oxygen level of the indoor air.

Important Parts Of A Central Air Conditioner That Need Regular Maintenance Are:

  • Air vent: The heating and cooling system contains a part called the air vent that is part of the ventilation process. The air is sucked in by the vent, passed through a filter and sent to the main AC system.
  • Filters: Filters are very important parts, as the outside air is drawn through them. The filter needs to be cleaned regularly to ensure there is no dust or debris build up on the filter. It is advisable to check filter condition and get it replaced if required.
  • Exhaust outlet: This part of the heating and cooling system is responsible for expelling the exhaust created by the heater. Regular checking of the chimney vent is recommended.
  • Duct: Apart from buying the right air conditioning equipment, it is very crucial to check the ductwork as well. It is best done by employing a professional contractor who can inspect if the currently installed ducts are in proper health. Checking for problems like poor sealing of joints and breaks in the ducts can lead to an average of thirty percent efficiency loss in energy. A professional contractor can provide a servicing of the ducts by cleaning and insulating them afresh.
  • Outdoor AC unit: This part of the system has a fan that controls the flow of air. It is very important to keep the fan clean of debris that is often sucked in by it.
  • The Compressor: It is a component of the outdoor unit of the heating and cooling equipment that does the work of converting the gas refrigerant to the liquid state so that it can reach the coil.
  • Coil: The coils are a part of the outdoor unit of the heating and cooling system. The refrigerant in the coil helps to cool the air that passes through it.
  • Blower: This is also a component of the outdoor unit that is responsible for drawing warm outside air into the main unit.


Choosing a warming and cooling framework is a drawn-out speculation, anyway, it is very generous. Considering the way that the normal existence of a focal cooling framework is over fifteen years, settling on an educated choice is fundamental, as it is a gear that can’t be changed without any problem. Likewise, the factor of the month to month working cost identified with the vitality proficiency of the framework should be considered genuinely.

While deciding on the right HVAC system, it is crucial to determine the proper size of the equipment. Undersized or oversized equipment will expend more energy, leading to increased operating costs. Another important aspect to consider is the initial installation expenses in comparison to the future costs of maintenance. It is not only the upfront buying price, a system low in energy efficiency with a lower purchase price will lead to a huge power consumption and may need frequent repairs leading to high maintenance costs.
