hvac terms, Cincinnati, OhioThere are many choices available when it comes time to chose the right HVAC unit for your Greater Cincinnati home or business. Each product has information using HVAC terms that can cause more confusion than clarity. 

Here are 10 popular HVAC terms you may come across when considering which type of system you want and which unit will be suitable for your needs.

  1. HVAC or HVACR - These two terms stand for heating, ventilation and air conditioning. The "R" stands for refrigeration. Some HVAC units can qualify for tax credits.
  2. Load calculation - This is a mathematical equation that determines how much heating and cooling capacity a home needs. With this calculation, you and a qualified technician can select an HVAC unit that provides adequate comfort for your home and runs efficiently.
  3. SEER, or seasonal energy efficiency ratio - This is one of the HVAC terms that rates energy efficiency. It's a measurement of how much energy is needed to cool a room. The higher the SEER, the more efficient the air conditioner.
