If you have ever lived or worked in varying temperatures, you have probably come across some kind of HVAC system. HVAC systems are intended to keep areas warm or cool, and building owners can tailor them to meet specific temperature control requirements. Heating, ventilation, and air conditioning (HVAC) refers to any system that offers airflow or temperature control for an area. There are several types of these systems, ranging from central air and heating to portable space heaters and AC units. Below are the main types of HVAC systems and explain how each one works to help you decide which heating or cooling system is best for you. For further inquiries or questions contact an experienced and reputable HVAC contractor.

Ducted HVAC systems

Heating and cooling split systems 

Split heating and cooling systems are the most frequent types of HVAC systems. As the name implies, it is divided into two independent units, one for heating and the other for cooling. It is key to note that these systems include both indoor and outdoor units that are clearly distinguishable.

A heating and cooling split HVAC systems have an exterior cooling system that employs compressors, refrigerants, and coils to cool air. As well as a fan to keep hot air at bay. These are the air conditioning units that are commonly stored outside the property and run during the summer. The heater in the heating and cooling split system, on the other hand, is located in a basement, utility closet, or other indoor storage place and uses gas to heat the property. In this design, a standard thermostat is utilized to regulate the temperature within a comfortable range.

Hybrid split system 

HVAC hybrid systems are similar to split systems, but with several major variances. These systems are becoming more popular because of their capacity to reduce energy costs through their electric hybrid heating technology, which distinguishes them from other types of HVAC systems. This hybrid design allows the option to switch from gas power to electric power instead. Each has its own benefits, using gas power to heat your property results in faster and more powerful heating. In contrast, switching to electric heating is not as powerful as gas but more energy efficient. The ability to choose between the two options is dependent on how the property owners wish to heat their space.

Hybrid HVAC systems tend to be more useful in temperate climates because of their ability to utilize electric heating during months when it is not too cold or too hot. This system employs typical ductwork and thermostats to deliver all of the benefits of a split system, but with the added bonus of energy conservation and lower utility bills.

Packaged heating and air conditioning system 

Packaged Heating and Air is the most specialized type of HVAC system. The system is a self-contained heating and air unit that is stored within the property. It is often stored in an attic or on the top level storage space and serves to both cool and heat a property. It is relatively tiny in size and makes it ideal for smaller places or dwellings, and it may be placed inside if an exterior option is not available. These HVAC systems may also be incredibly efficient and simple to maintain. Since a packaged heating and cooling system is not as strong as the other designs, they are often utilized in warmer areas. Heat is often created electrically, however alternative types can mix gas and electric capabilities. Since these units tend to run smaller in size they can be easier to maintain.

Zoned system 

HVAC zoning systems provide building occupants more control over the temperature in different rooms or spaces. Technicians may zone ducted HVAC systems in a variety of ways, with the optimal option frequently being determined by the size of the property. People who own larger homes or commercial spaces, for example, may opt to install various HVAC systems to adjust the temperature on separate levels. Since each system is totally independent, building owners must install two or more heating and cooling units.

Another typical method of zoning is to put manual or automatic dampers in the air ducts of a system to control the quantity of airflow in different locations. Partially shutting a damper restricts airflow to one zone while pushing it toward another, making it simpler to set each room’s suitable temperature. This kind of zoning increases energy efficiency by moving air away from zones that do not require it and produces a more pleasant atmosphere for all those on the property. Compared to other HVAC systems the zoned system allows for more personalized temperature control that can cater to all those in different spaces.

Duct-free systems

Duct-free mini split 

Ductless mini-split systems are commonly found in multifamily residences, office buildings, and hotel rooms and are placed in individual rooms. These electric devices, sometimes known as mini-split systems, feature an exterior compressor and condenser, refrigerant, an internal air-handling unit, a heat pump, power connections, and a thermostat for each zone. The interior and outdoor components are linked by copper tubing, and one compressor may power up to nine inside air-handling devices.

Ductless systems frequently assist to cut energy expenses and usage over time. Along with its adjustable zoning features, users may only heat and cool occupied rooms, minimizing energy loss associated with ducting. However, the heating components are less efficient in temperatures below freezing, so persons living in colder climes may need to install a separate heating system.

Portable spot cooler 

Spot coolers are portable air conditioning equipment used to chill large rooms, manufacturing buildings, or outdoor areas. They operate by sucking in ambient air, passing it through a closed-loop coil chilled by the refrigerant, and returning it to the area. The coil cools and dehumidifies the air, leaving behind condensation that drips into a hose or catch bucket. Spot coolers may be used anywhere there is an electrical power supply, and the connected wheels make them portable. However, finding a location to vent the exhaust might make setup in small places more challenging. After chilling the air, spot coolers expel any remaining heated air through a flexible exhaust tube. To prevent heated air from re-entering the area, this tube is normally extendible and must exit by a door, window, or drop ceiling.

Portable heat pump

A portable heat pump is similar in size and performance to a spot cooler, but it also provides warmth in colder climates. When turned on, a heat pump sucks in outside air, passes it over a condenser coil, and distributes warm air throughout the room. Owners may convert between heating and cooling capabilities using a reversing valve inside the machine, making it a viable alternative for different climates.

There are many different types of HVAC systems with their own use cases.  The split system is the most common, however, hybrids are becoming more popular due to their energy efficiency. Duct-free systems are ideal for families that have varying temperature preferences or for businesses in the service sector such as hotels and different kinds of accommodations, while packaged heating is ideal for tiny spaces or warm climates. Each type of HVAC equipment has advantages and disadvantages, and an HVAC contractor will help you navigate them. A properly trained and experienced HVAC contractor can also properly install the system that your property needs, whether that be an extensive ducted HVAC system or a more simple duct-free system, they have you covered.
