The Lingo of HVAC

The lingo of HVAC can be daunting for some – but, here’s the definition of five phrases and acronyms.

AFUE – Annual Fuel Utilization Efficiency is similar to SEER but pertains to furnaces. Heating products with higher AFUE use less energy – and fewer dollars – to heat up a home.

MERV – Minimum Efficiency Reporting Value is the number that represents the precision and accuracy of an air cleaner, which reduces pollen levels and humidity within a home. Overall, an air cleaner’s performance is determined by the amount of particles it catches. Higher MERV ratings correspond to a greater percentage of particles captured, which lowers energy usage and improves air quality.

Zoning – If you want the bedroom to be 68 degrees but the living room to be 74 degrees, zoning is what you are looking for. With new technology, zoning helps segment a home so certain rooms, typically in a larger home, can have different temperatures while using the same central heating and cooling system.

Heat Pump – Don’t be misled by the “heat” in “heat pump,” as a heat pump can heat and cool a home. Ideal for climates with milder winters, a heat pump provides cooling in the same way an air conditioner does, but also can heat a home by converting cold air to warm when needed. In some climates, using a heat pump instead of an air conditioner and furnace can yield significant energy savings.

Mini-SplitA mini-split is a system that can heat up or cool down a space without adding ductwork. It’s best suited for smaller or converted spaces, such as garage apartments or sun-rooms, which take less time to reach the desired room temperature than a larger space and where the expense of adding ductwork can be avoided.
