What Are The Most Common Types Of HVAC Systems?

Consider the type of HVAC system you want in your home, regardless of whether you are building a new home or want to upgrade the heating and cooling system in an existing home. This system will determine the comfort level in your home throughout the summer and winter months.

Most Common Types Of HVAC Systems

Split System

Our HVAC contractors in Arlington, TX, recommend split systems in residential buildings. They consist of two independent components, one for heating and one for cooling, and utilize a typical thermostat to keep a constant temperature throughout the entire structure.

In most buildings with split systems, the heating unit is located in the basement, a utility closet, or another interior storage space. In contrast, the cooling system is located on the building’s exterior. It is connected to the ductwork inside the structure by a series of tubing runs.

Geothermal Systems

Geothermal systems utilize the earth’s temperatures to heat and cool buildings. Water containing refrigerant is routinely pushed via submerged or underground pipes to collect or release heat.

Geothermal HVAC systems are four times more efficient than conventional ones. There is a significant reduction in both energy use and associated expenses. However, the most critical cause for concern is the cost of geothermal HVAC systems.

Gravity Systems

In mechanical systems, the principle that hot air rises and cold air fall is fundamental to how gravity works. As a result, systems that rely on gravity are not suitable for distributing cool air from an air conditioner. In such systems, the furnace is typically located close to or below the floor, so heat registers must be positioned higher than the furnace. They are often placed on the walls at a high level when the furnace is on the main level to prevent the need for heat pump repairs in Arlington, TX. As the air cools, it sinks and enters the return air ducts, where the furnace eventually reheats it.

Ductless Or Mini-Split Systems

Ductless systems, otherwise known as mini-split systems, are another standard HVAC system in residential structures. In this instance, no ductwork nor a central heating and cooling system are present. Instead, separate heating and cooling systems are positioned in different areas around the residence.

According to our HVAC contractors in Arlington, TX, ductless systems might be an excellent option when constructing a home addition. However, their maintenance requirements may be more significant since they have multiple units.

Packaged HVAC System

A packaged HVAC system contains essential components in a single outside cabinet. Packaged systems utilize a blower to propel purified air into the building. These systems may use a gas furnace/air conditioning unit, heat pump, or both for temperature regulation.

In residences without basements, packaged systems are sometimes used. Due to the unit’s location outside the dwelling, these systems are less noisy than alternatives. However, packaged systems have a lower energy efficiency than split systems and deteriorate more rapidly when exposed to the weather.
