A Glossary of Cincinnati HVAC Terms, Part 2

Cincinnati heating company

Here’s a continuation from last week’s post about the terms used in the heating and air conditioning industry here in Cincinnati. While it is not necessary to know these terms to keep your heating and air conditioning system running at maximum capacity and efficiency, you may be curious to learn some of the language used in the world of Heating, Ventilation, and Air Conditioning (HVAC).

Heating load: This measurement tracks the amount of heat flow your home requires to keep its temperature steady. It is measured in British Thermal Units (BTUs).

Indoor air quality (IAQ): We use IAQ to describe how much pollution is in the air.

Minimum Efficiency Reporting Value (MERV): The MERV ratings tell us how big the holes are in furnace filters. If the rating is high, the holes are very small, and the type of particles that can pass through such a filter must be miniscule.

Negative pressure: If you suck more air out of a room that goes back into, you create negative pressure. In removing heat from air, or redirecting a room’s air, your HVAC system may create negative pressure.

Plenum: The joint where a duct connects to an air handling unit – that is a plenum.

Radiant barrier: The foil sheeting you see in the attic, which keeps heat from entering your home in warmer months, is given this poetic name.

Return duct: When your system recycles air from inside the house, either to heat or cool the home, it goes through a return duct.

Seasonal Energy Efficiency Ratio (SEER): This ratio describes the efficiency of an HVAC system, and it notes how much energy you use to heat and cool your home throughout the year.
