There are times when the weather condition is at extreme. It could be so cold during the winter or unbearably hot during the summer. This can be mitigated by having an effective Air Conditioner (AC) or furnace. As weather conditions vary, so does the need to utilize either an AC or furnace to make your home livable. 

Sometimes in the winter, you can find it extremely hard to stay in your home or office without an effective furnace. This helps cushion the prevailing cold at such times. Also, coping during the summer can be equally difficult without a functional AC. However, there are times when your heating, ventilation, and air conditioning (HVAC) system may be acting up. At such times, you will need a technician to help fix it. You can check out Servtech Air Conditioning Solution to know more about services that HVAC technicians offer. 

It is important your HVAC system functions optimally at all points. When there is a fault with your system, it is always advised to seek professional help. 

What is HVAC System

This is the deployment of varied technologies aimed at controlling the humidity, temperature, and purity of air that circulates in enclosed spaces. The aim is to ensure thermal comfort as well as good air quality indoors. HVAC system is a branch of mechanical engineering. It relies on the principle of fluid mechanics, thermodynamics, and heat transfer. This forms an essential component of residential buildings like single homes, hotels, apartment building, advanced living facilities etc.

Additionally, means of transportation such as airplanes, cars, trains, ships as well as submarines utilize these systems to control temperature.     

Types Of HVAC Systems

There are different types of heating or cooling systems that you can deploy in your home or office for maximum comfort and relaxation. Some of them are discussed below: 

Split System 

This is an outdoor component that contains the condenser as well as the compressor. It also has an indoor component that contains the evaporator coil as well as blower.  This is famed as one of the most sought-after system for residential buildings. Its indoor unit is usually attached to a furnace/heat pump. 

This form of air-conditioning and heating system mostly have the following: 

  • Outdoor unit which usually contains the compressor, electrical components, condenser coil, and fan(s).
  • A refrigerant that flows from and to the indoor as well as outdoor unit through pipes.
  • Blower that circulates air over chilled evaporator coil. 
  • Ducts that transmit air through the building. Supply and return ducts serve to bring in as well as blow out air respectively.
  • A thermostat which regulates the systems. It also sets desired temperature. 

Hybrid System 

This system allows a heat pump which is electricity powered to be used together with a furnace. The furnace usually burns propane, gas, or fuel oil. In keeping with what the name implies, these forms of systems also serve to cool one’s home. 

Heat pumps are actually air conditioners that also work in reverse forms to adequately heat one’s home. It is a system that performs dual role of heating and cooling your home. 

They have a furnace which functions when the temperature goes below 40 degrees. When the weather is cold, a heat pump transports air from the outside into your house. Also, when it gets hot, it serves like the air conditioner. Consequently, one product offers you round the clock energy savings. Read this article to garner more knowledge on the functionality of HVAC systems. 

Most hybrid heat system have the following: 

  • Heat pump which heats as well as cools refrigerant. 
  • A furnace and evaporator coil which help to convert the refrigerant and circulate air. 
  • Ductwork that channels air within a building. 
  • Thermostat that adjusts and controls the system. 
  • Optional accessories that improve indoor air standard. 

Ductless Mini-Split system 

This system provides answers to spaces where regular ducted systems are not compatible. They are equally good compliments to already existing ducted variants of HVAC systems. 

They are fixed directly into areas of your home that require heating as well as cooling. It gives one the ability to have up to four indoor units for every unit outdoor. 

Ductless mini-split devices usually have the following: 

  • Outdoor heat unit that houses the compressor. 
  • Compact fan coil.
  • Wires for refrigerant linking the unit outdoor to fan coil.   
  • The thermostat also known as control panel.
  • Optional accessories that help clean air and ensure it is pleasant prior to distribution throughout your house.  

Packaged System  

This system houses compressor, evaporator and condenser in single unit usually situated on the roof or close to the foundation. 

It serves as an efficient option for offices and homes without enough space for every separate piece of a split system. They are also used in small commercial structures and usually have electrical coils for heating.  

Package systems usually have the following:

  • An air conditioner or heat pump along with an evaporator or fan coil in a single unit. 
  • A thermostat for full control. 
  • Optional quality air improvers such as cleaners, purifiers, ventilators etc.  

Importance Of HVAC System

Every home should have a durable system for cooling and heating, depending on the prevailing weather conditions. Some of their benefits are discussed below: 

Climate Control 

They help control the prevailing climate in your home. Also, these systems are important to make necessary adjustments whenever changes occur in outdoor temperature. Boilers and heaters can keep your indoor temperature tolerable during winter season. On the other hand, they regulate existing air temperature during hot seasons by providing needed cooling for comfort. 

Increases Productivity 

The level of productivity among members of staff is increased when the office climate is comfortable. It is difficult to have an employee perform at top level when the office is freezing or too hot. Hence, having a cooling and heating system in your office, will make your staff more productive.  

Improves Air Quality

Not only do good HVAC systems regulate temperature within a building but also improve quality of air that people breath. A good system will reduce humidity in the air to ensure people can enjoy a cozy atmosphere.  

Given their importance, it is however, important that you put your budget into consideration before deciding on the best option for your home. Go to for tips on how best to budget for your needs. 


This article has hopefully improved your knowledge of cooling and heating mechanisms. To avail yourself of more knowledge, consult an expert within your area. It is important to note that your choice of a system is greatly dependent on the size of your building and the purpose.
