You wouldn’t buy a new car without knowing the main features you are looking for and how the most important parts work, and looking at HVAC systems shouldn’t be any different. Understanding common terms in the industry will help you communicate with salespeople, technicians and consultants. Here are some of the most prevalent HVAC terms you should be aware of:
- Annualized fuel utilization efficiency (AFUE): This term is widely used to express the efficiency of furnaces. The higher the AFUE, the better a unit is at turning fuel into usable heat.
- British thermal unit (BTU): This unit is a standard in the HVAC industry when measuring heat energy. It is the quantity of heat that is needed to heat a pound of water up one degree Fahrenheit. A system with a large BTU rating has a greater heating capacity.
- Cubic feet per minute (CFM): The standard metric for airflow is CFM. Having a sufficient airflow through your ductwork is crucial for proper HVAC performance.
- Heat exchanger: Many parts of your air conditioning system involve transferring heat from one substance to another. A heat exchanger allows multiple streams of liquids or gases to pass by each other and pass heat, which effectively allows you to cool coolant or heat air.
- Split system: The most common type of HVAC system is a split system. This means that rather than having all the equipment in a central location inside the home, some of it is inside and other parts are outside.
- Zoning: It is now possible to divide your home into different sections and cool or heat them as needed with a zoning system. This allows you to maximize efficiency and comfort.
