Defining an HVAC System

HVAC is also known as Heating, Ventilation, and Air-Conditioning. The system is made up of different parts joined together to perform certain functions like cooling, ventilation, and heating to regulate the temperature inside a building.

The heating and air conditioning system also helps in controlling the humidity of an indoor environment to ensure the inhabitants of the house enjoy top-notch climatic conditions.

In Los Angeles, many homeowners agree that the services of a HVAC repair company is always necessary.

Los Angeles HVAC contractors play a crucial role in the maintenance of their HVAC equipments. Their services is also used in museums to preserve historical artifacts.

Categories of HVAC Systems

The HVAC system can be divided into 4 major categories, these include – hybrid systems, split systems, packaged heating and air systems, and ductless systems.

Users can pick the one that is in line with their budget and homes.

  • Split system: This is the most widely used HVAC system and it comprises two units built specifically for heating and cooling.
  • Hybrid system: This is similar to the split system, however, it is an energy-saving system because it is fitted with a hybrid electric heater system.
  • Ductless system: This system cools and heats the house through an external air conditioner and a heat pump. It is effective in buildings that do not have the conventional duct system in place.
  • Packaged system: This system is common to houses with no basement and is usually placed outside the homes. It has a single unit for both heating and cooling.

Understanding The Role of Heat Pumps

Certain air conditioners are produced from a conventional system known as a heat pump.

The difference between a heat pump and an air conditioner is that the former can pump heat in two directions while the latter can only pump heat in one direction.

Heat pumps can be used for both heating and air conditioning, thus, users can regulate indoor temperature without using the furnace until the temperature is freezing.

Also, heat pumps are frequently used in relatively cold areas. Recent technological advancements have made heat pump more adaptable to freezing weather.

Difference Between Commercial and Residential HVAC


Except the HVAC system is meant for the home of a billionaire, commercial HVAC systems are usually bigger than home HVAC.

Commercial HVACs are larger because they are used to heat and condition bigger buildings.

A standalone unit is commonly used in residential houses while a commercial building comprises a modular unit.

Although, the components of a commercial HVAC are placed together to ease setup and maintenance.

A residential heating and air conditioning unit can weigh up to 5 tonnes while modular rooftop units range between 10 to 50 tonnes. Also, the components used for a commercial HVAC are more powerful.


The split system is peculiar to a private home, and the indoor unit is usually located in secluded places like the attic, closet, or basement while the outdoor unit is placed beside the building or in the backyard.

More often than not, commercial buildings tend to use a packaged HVAC system that is usually installed on the roof.

Although in some situations the system is located beside the building or in the basement.

The rooftop is considered the ideal location for commercial HVAC because it reduces noise, provides space, and doesn’t impede movement.
