HVAC System Types & Key Features to Keep in Mind


HVAC is short for Heating, Ventilation, and Air Conditioning. These systems help to make indoor environments comfortable and suitable for homes and businesses and are currently available in four different types.


Heating and Air Conditioning Split System

The most classic type of heating and air conditioning system

Consists of:

— Components of the system are both inside and outside the building

— An Air conditioner that cools the refrigerant

— Furnace and a fan to convert the refrigerant and circulate the air

— Ducts that carry the air all through the building

— Thermostat to manage and control the system


Hybrid Heat Split System

An advanced version of the HVAC split system that has improved energy efficacy

Consists of:

— Heat pump that heats or cools the refrigerant

— Furnace and evaporator coil for conversion of the refrigerant and air circulation

— Ducts to channel air around the building

— Control panel to adjust and control the system


Duct Free Split Heating & Air Conditioning System

— Great for areas where convectional systems with ducts can’t go

— This system is also a good compliment to existing ducted HVAC systems

Consists of:

— Heat pump or air conditioner to heat and/or cool the refrigerant

— Compact fan coil

— Wire and tubing for the refrigerant that connects the outdoor unit to the fan coil

— Thermostat or control panel


Packaged Heating & Air Conditioning System

Good solution for homes and offices without adequate space for the separate multiples components of the split systems

Consists of:

— Air conditioner and heat pump together with the evaporator and fan coil in one unit

— Thermostat or control panel


Now that you know the four different types of systems, it is important to consider the different features of HVAC systems.


Features to consider:

Refrigerant- There are different types of refrigerant that can be used in HVAC systems. Consider implementing environmentally friendly refrigerant such as R-410A.


Location of indoor unit- Furnaces mounted in closets and floor level areas are less prone to cause leaks and water damage. Consider this before placing indoor units in attics and higher level areas that are more likely to leak and cause ceiling damage.


Location of outdoor unit- Outdoor units should be put in areas where they are least likely to be seen, heard, or damaged. Consider this before places outdoor units by bedroom windows.


Air-filter location- Air filters should be replaced every three to four months, so it is important to place these filters within easy reach.


Filter dryer- Consider installing a filter-dryer to extend the compressor life. The filter dryer removes damaging moisture and grit which keeps the system running more efficiently and helps it to last longer.


Design and balance of ductwork– Make sure that the ducts are sized and balanced around the home to ensure comfort. Externally insulated round ducts tend to be the most efficient.


Keeping in mind these features will help you to install the most efficient and comfortable HVAC system and will keep your customer happy and satisfied.
