When it comes to the heating and cooling systems in your home, there is a lot you may never know, instead of relying on professionals. Many of these intricacies can be hard to comprehend and you don’t need to know the ins and outs. However, to properly communicate with the experts you call in, there are some basic terms it can be helpful to understand. This will let you follow your technician’s thought process, and also to be able to ask questions. Below are some of the most important terms you can learn to feel comfortable discussing your HVAC system.
HVAC: Even the name itself is a term to understand! While you may understand the overarching term, you may know what your HVAC system is specifically. It actually stands for heating, ventilation, and air conditioning systems. These heat and cool your home, as well as providing clean indoor air.
MERV: This is a measurement scale that is used to rate how effective an air filter is, and the acronym stands for Minimum Efficiency Reporting Value. MERVs range from 1 to 16, with a higher number indicating a higher ability for a filter to catch particles in the air.
BTU: Short for the British Thermal Unit, a BTU is au nit of heat from the British Imperial system. It conveys the amount of heat that will raise the temperature of a pound of water by one degree Fahrenheit. The BTU will usually be displayed as a number 1 through 5 on your unit.
HSPF (Heating Seasonal Performance Factor): This is used to measure the efficiency of an air source heat pumps. It can also be used on air conditioners. A higher HSPF rating indicates a unit is more energy efficient.
SEER (Seasonal Energy Efficiency Ratio): The SEER is more commonly used to rate the energy efficiency of air conditioning units. This is calculated using the cooling output divided by the total electrical input in the same season. Again, the higher the unit’s rating, the more energy-efficient it will be.
CFM: CFM, or cubic feet per minute, shows the velocity at which air flows in to or out of an area. To determine the heating needed for a particular room, you would multiply the volume of the room by the number of times the heated air is changed hourly. You then divide that number by 60 to determine the necessary amount of CFM.
Load Calculation: This is a method used to determine the heat gain and loss of a structure, which helps to determine the proper unit size for a home or commercial property. A unit that’s too big will lead to wasting money and energy, while a small unit may not properly regulate your home temperature. Your technician will help determine the proper load calculation based on the specifics of your home’s layout.
While these terms are helpful to understand, you’ll still want to rely on experts to make decisions for your home and to do the necessary work. At Comfort Experts, we will help you to understand our recommendations based on our experience and work with you to execute this plan.
