The heating and cooling systems in your home are essential to your overall comfort. Part of keeping them running well is to understand how they work. There are many terms that are used in the HVAC world that can seem confusing if you don’t understand what they mean and how they fit into your heating and cooling systems. Air Supply Heating & Air Conditioning is here to talk about common terms used in the HVAC industry so that you can have a better understanding of how your systems work within your home.
HVAC Terms & Definitions
Following are some of the terms and abbreviations that you should be aware of pertaining to your HVAC system:
– AC (Air Conditioning): The appliance found in many houses to remove warm air an dehumidify it. The air is then exchanged for cooled or cold air that is distributed throughout ductwork and blown out through vents.
– AFUE (Annual Fuel Efficiency Ratio): This is a measurement of your furnace or boiler’s efficiency. This will tell you how much fuel your heating system requires to heat your house and how much energy is lost through exhaust. If your AFUE rating is below 80% you should look into replacement of your furnace or boiler.
– Coils: There is both a condenser coil and evaporator coil in your HVAC system. The condenser coil is in the outdoor unit and the evaporator coil in located in the inside unit. They either work to raise or lower the temperature using heat transfer.
– Ductwork: The intricate system of metal pipes that work to disperse the hot or cold air coming from your HVAC system throughout your home.
– Heat Exchanger: Inside your furnace there is a heat exchanger that is responsible for transferring heat to the surrounding air and then is pumped through your house.
– Heat Pump: Responsible for moving hot air, this pump works to bring in the heat from outside in the winter and then removes heat from your home during the summer.
– Split System HVAC: When you have a split system in your home the HVAC system will include both a unit inside and outside your home.
– SEER (Seasonal Energy Efficiency Rating): Your AC unit is given a SEER rating to categorize its efficiency. The higher the number, the more efficient it is.
– MERV (Minimum Efficiency Reporting Value) Rating: The MERV rating is given to air filters which play a vital role to your HVAC system. The higher the MERV rating, the better the filter is at removing particles from your air.
– HVAC Zoning System: For those that want their heating and cooling to be customized throughout the house, this is what you are looking for. Using dampers within the ductwork, heated or cooled air can be customized for different zones in your home; keeping some areas cooler or warmer than others.
