Factors in your HVAC Selection


A few decades ago, opening and closing a window was enough air temperature control. In modern days though, the standard bar of comfortable living has become higher and the occurrence of global warming, which raises the world’s temperature to the extremes, is abundant.  With all this in mind, temperature control becomes a major necessities. During this post, we will be exploring factors which should be considered for a new installation of a HVAC system either to modern or conventional homes.

Regardless of the size of property, ductwork that is balanced and well designed must be installed to make sure that the air and temperature circulation is optimal –especially for locations with extreme weather conditions. Externally insulated round ducts are found to be the most efficient. Installation of balance dampers in the ductworks should also be important to regulate airflow.

End users should also be paying attention to materials of the HVAC unit. The condenser coil type directly relates to the reliability and stability of the HVAC unit, which is even more important in harsh environments. In common applications, coils which are made from one types of metal are usually more reliable and generate better efficiency.

HVAC application has several types of working fluids also known as refrigerants. The main function of refrigerant fluid is to cool, dehumidify and distribute the low temperature air in the system. For a long time, R-22 or Freon happened to be the most common refrigerant in the market. Nowadays though, the use of Freon has been banned for the reason of being environmentally harmful.  Currently, there are a couple other refrigerants that are commonly implemented in such application including R-134a, R-407c and many more. Those refrigerants have their own advantages and disadvantages which end users should compare themselves to see what would fit their needs the best.

Efficiency should be the most important aspect to study before settling on a type of HVAC system. There is minimum efficiency which is settled by the government, though aside from legal limit, this would be an ultimate factor to be analyzed by users since efficiency directly correlates to operational costs (the higher the SEER, the lower utility bill you get). Thus, an up-front investment might benefit in the long run.
