HOME HEATING AND COOLING
Heating and cooling are two of the most important concepts of home ownership. In fact, heating and cooling systems are major factors for those looking to purchase homes, and are a critical aspect of comfortable indoor living.
You may frequently hear the term "HVAC," which is used to describe home heating and cooling systems. The acronym stands for Heating, Ventilation and Air Conditioning—which are the 3 primary functions of a home system. They control air temperature and humidity, and maintain the quality of the air in the home.
TYPICAL Residential systems are called CENTRAL AIR or SPLIT SYSTEMS
A central heating and cooling system produces warm or cool air in one central area and then distributes it throughout the home. There are many types of systems that work as central systems, from traditional split systems to packaged product systems.
The term "thermostat" commonly refers to any unit that controls the operation of a heating and cooling system. Thermostats are used to turn on heating or cooling systems to bring the home to a set temperature. In addition to basic temperature control, programmable thermostats can be used to program the timing of the system’s functions, which can control overall energy use and costs.
A variety of type systems are available besides the CENTRAL AIR or SPLIT SYSTEMS System, There are also PACKAGE UNITS, MINI-
Efficiency Ratings Explained
SEER (Seasonal Energy Efficiency Ratio)
The measure of efficiency by which the cooling process of air conditioners and heat pumps are rated. The higher the SEER number, the greater the efficiency–and therefore greater energy savings. Today, regulatory agencies require all new products to have a 14 SEER rating or better.
AFUE (Annual Fuel Utilization Efficiency)
The standard measurement of efficiency for gas and oil-
HSPF (Heating Seasonal Performance Factor)
The efficiency measurement used to gauge the efficiency of the heating mode of heat pumps. The higher the number, the greater the efficiency and cost-
One additional factor that affects the efficiency of your air conditioning or heat pump system is your indoor coil (also called an evaporator coil). If your condensing unit is not matched with the proper indoor coil, it may not give you the stated SEER and/or HSPF ratings and could even develop performance problems. When you replace an existing system, make sure you replace both units so your new condensing unit will give you optimal performance, efficiency and comfort.
