Types Of HVAC Systems

Lots of HVAC systems are widely available in the market. To decide which of them would be able to satisfy your cooling and heating needs, you have to be conversant with their distinct features and functions. This knowledge will not only help you make the best decision, but a waste of resources (money) will also be avoided as well.

Below are some examples of HVAC systems widely available in the market.

1. Heat Pumps

Simply put, a heat pump is a type of HVAC system designed to create both heating and cooling effects. 

Unlike other types of HVAC systems, the heat pump runs without fuel, rather it transfers heat from one surface to another or from one medium to another because it obeys the natural law of heat. (i.e that heat moves from a warmer body to a cooler body)

Some people prefer heat pumps rather than other types of HVAC systems that run on fuel because to an extent, it saves cost. There are three types of heat pumps; absorption, air source, and air-ground. 

Homeowners should make proper inquiries about every one of them before finally deciding which to settle with.

2. Furnace

A furnace is a home appliance that creates the heat being dispensed by the central heating system. This heat is distributed in every corner of the house to keep the house warm and comfortable especially during the winter when the environment can be very chilly. 

The gas furnace is made up of a flue or vent pipe, a heat pump exchanger, a burner, and ductwork. 

Many homeowners prefer to buy this type of HVAC system because it is very effective and durable, running for up to 25 years and sometimes beyond that. 

The main disadvantages of the furnace are that it gets dirty easily and is difficult to clean therefore serving as a breeding ground for microorganisms. 

Maintenance of a furnace requires professionalism. This should be done thoroughly and regularly especially before the winter period commences to ensure a warm and comfortable environment for members of the home.

3. Boiler

What you have here is another type of HVAC system that distributes a natural kind of heat. They can run on different types of fuel ranging from coal, oil, and natural gas. 

The fuel is preserved in a container that undergoes a chemical reaction and radiates heat in the process. In comparison to the other systems, the boiler system releases the most pleasant heat with perfect air quality.

In addition to producing pleasant heat, boilers do not pump dry and hot air. Boilers release heat via pipes to power radiators thus ensuring a quiet heating system. The noiselessness of its operation makes it attractive to many people. 

Everyone would prefer to have an atmosphere where your home is kept warm and cozy without the interference of too much noise coming from the cooling system.

4. Mini- Splits

Mini-splits are popularly known as ductless split systems. This type of cooling and heating system offers you the opportunity to be in control of the temperatures of every compartment or space. Mini-splits are known to be very quiet thus making them more suitable for the home, especially at night. 

As a house owner, there are a lot of benefits one could enjoy after having installed this ductless split system. But because it has to be cleaned and repaired daily, this traditional system is often too expensive to keep up with.

Installing Mini-splits is quite easy and does not waste much time. However, you shouldn’t be tempted to start installing your own A.C. unit by yourself even after you have read the central air conditioner installation guide. 

Always employ the services of an expert. Mini-splits are automatically operated with a wireless remote. They consist of both indoor and outdoor units that are linked by a conductor further making operation easier. 

5. Geothermal

For various reasons, recent house owners aren’t so eager to embrace some great technology such as geothermal heating systems. These reasons notwithstanding, geothermal is not an option to ignore. It is environmentally friendly and also saves money on energy bills. 

Being the most modern form of heating system, the latest technology in the HVAC industry has been utilized in its production. Like other HVAC systems, the geothermal system functions with refrigerants but because they are environmentally friendly, they do not discharge it into the environment. Instead, the system stores it and makes use of it after some time.

The refrigerants move in circles along long curves that are fixed underground in your building. Deep below the ground, the temperatures do not fluctuate therefore preserving the refrigerants is conservative and saves energy.

  • Warranty: You must be aware of the warranty term for the product you wish to purchase.  Make sure you are aware of incidents that might jeopardize the lifespan of your system and how to avoid them.
  • Efficiency rating: Every HVAC system possesses the annual fuel utilization efficiency (AFUE), seasonal energy efficiency ratio (SEER), heating seasonal performance factor (HSPF), or energy efficiency ratio (EER) ratings. When the rating is high, it signifies that the effectiveness of the unit is high too.
  • Durability: Although  HVAC systems are recognized as durable, lasting for several decades, some start developing issues in the 10th to 15th year of purchase.
