What are the Different HVAC Systems to Consider?

HVAC Systems HVAC Systems

There are different HVAC systems that homeowners and business owners need to consider when choosing the system that is appropriate for their particular needs. Two such systems are the cooling only split system, cooling only packing system, heat pump, chilled water system, window air conditioners and packaged terminal heat pump.

Split System

What is the cooling only split system? It is a blend of outdoor condensation and indoor air handling. The unit for handling indoor air consists of a cooling coil and air supply fan as well as the expansion apparatus. The unit for condensation contains a condenser coil and compressor. These make up the split system, usually found in small commercial offices and residential homes. If you are looking for a high energy efficiency rating for your air conditioning systems, then this split system is recommended. System manufacturers have been required to increase the EER rating to offer varying degrees to accommodate various seasons. If the building requires heating, then a different method is used, but it is generally in the form of gas or electric.

Packaged System

The cooling only packaged system is a sole unit with a combination of the same elements in the split system. The unit has to be installed on the exterior of the building since it is packaged. The indoor air has to be ducted away from the building and enter through the utilized air distribution system. The SEER rating for the packaged system starts from 10 and goes up to 18. In a situation where heating is necessary, a different method is used, which is generally gas or electric.

Heat Pump

HVAC systems that offer only cooling are similar to the heat pump, but with a single exception. Heat pumps have a unique valve found in the refrigeration piping, which allows the cycle to run in the reverse. The cooling only system works by cooling the air indoors and rejecting the outdoor heat. The heat pump works by cooling the air indoors and upon reversing the valve, it can heat the air indoors.

Window Air Conditioners

An air conditioner unit installed in a window or customarily in the opening of a wall is usually accommodated by some homeowners and business owners. This option should be the last resort since a window unit only cools a small and confined space.

Packaged Terminal Heat Pump

The window air conditioner unit and the packaged terminal heat pump are quite similar in features. They are installed through a wall opening and are self-contained, requiring electrical connection. The downside is the noise that is emitted and the high operating cost.

Conclusion

Choose from the list of HVAC systems wisely. You can receive recommendations from an experienced HVAC contractor before you go ahead and purchase one. You will also need help from an HVAC contractor to install your system.
