There 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.
4. R-410A refrigerant - Air conditioning systems use refrigerant. R-410A is a refrigerant used in today's A/C production that contains no chlorine and is more environmentally-friendly than the former refrigerant standard, R-22.
5. BTU, or British thermal unit - It's a measurement of the amount of heat needed per pound of water to raise the temperature by one degree Fahrenheit.
6. AH or AHU, short for air handling unit - An air handling unit is the term used for equipment that uses a heating or cooling element enclosed in a cabinet or case.
7. ERV, or energy recovery ventilator - The function of the ERV is to draw fresh air into a room and force stale air out.
8. Energy Star rating - Energy Star is a government branding system used to identify and rate how energy efficient a product is.
9. Zoning system - This is the term for a single HVAC system that responds to thermostats that correspond to different areas of a home, referred to as zones. 
10. PMA, or planned maintenance agreement - Many homeowners sign on for a PMA when they purchase a new HVAC system or for older models. These agreements provide a schedule for routine maintenance visits.
