If you are looking to purchase any new heating, ventilation or air conditioning (or HVAC) equipment, knowing some of the key terms is important to making the right selection. By understanding the key words and gaining knowledge before you make your purchase you will make purchasing the most efficient product a lot easier. Understanding and familiarizing yourself with the terms noted in this article will give you the ability to have the information necessary in order to save yourself a lot of money over the long run.

Annualized Fuel Utilization Efficiency (AFUE): Tells you the amount of energy your furnace is changing into warmth. The higher the AFUE rating, the more energy efficient your furnace is. The Department of Energy regulates that all furnaces must have an  Annualized Fuel Utilization rating at a minimum of 78 percent. In most cases, an energy efficient furnace will have an AFUE score of at least 80%. A furnace that is superior to other units at consuming energy efficiently, will have an AFUE score of 90 percent or more. When shopping for a furnace, the AFUE rating of the unit will dictate the amount of money you will save on the cost of your monthly utility bills.

Seasonal Energy Efficiency Ratio (SEER): The Seasonal Energy Efficiency Ratio tells you how effective an air conditioning system is at providing cool air for your home. The higher that the system's} Seasonal Energy Efficiency Ratio score is, the more energy efficient it will be at keeping your home cool. The Department of Energy regulates that, any residential air conditioning system that was manufactured post-2005 must have a Seasonal Energy Efficiency Ratio score of a minimum of 13. By buying an air conditioning system with a higher SEER score, you can save yourself a large amount of money every year on the cost of your utility bills.

North American Technician Excellence (NATE): NATE is a third-party non-profit organization that gives certification to HVAC technicians. The organization makes sure that any technician who gets the certification is well-qualified for the work they do and has the ability to provide customers with excellent assistance on any heating, ventilation and air conditioning equipment. Heating, ventilation and air conditioning technicians who don't have the proper certification are not quality options for the job. It is always very important to ask your contractor if they use experts that are NATE-certified.

Minimum Efficiency Reporting Value (MERV): A unit's Minimum Efficiency Reporting Value will inform you on how effective a filter is. It does so by informing you of the size of the holes in the air filter. A higher MERV rating means that the holes on the filter will be smaller. The smaller the holes are on an air filter the more effective that filter will be at eliminating health-threatening particles from the air. The MERV scale ranges from 1 through 16 with 16 being the best.
