Knowledge is power. Sometimes homeowners in Dunedin, Florida, feel powerless when their HVAC contractor is spouting off strange jargon that makes no sense. After today, you’ll never have to feel like that again. Learn these important HVAC terms to better understand your system and the improvements that your HVAC service technician suggests.


AFUE stands for Annual Fuel Utilization Efficiency – an efficiency rating for your HVAC system. The higher your AFUE rating, the more efficient your system. As a result, you benefit from lower utility bills.


The big one. Maybe you’ve gotten by with knowing that this acronym had something to do with your heating and cooling system. But maybe you didn’t know that it stands for Heating, Ventilation and Air Conditioning. 

In the industry, we use this general term to refer to everything involved in your heating and cooling system.


This acronym refers to one of the most important aspects of your home: your Indoor Air Quality. IAQ is influenced by the particles in your air, humidity and many other factors that determine the health of your living space.


You may have heard about a MERV rating when your service technician was discussing your indoor air quality. MERV stands for Minimum Efficiency Reporting Value, and it refers to the efficiency of an air filter. 

The higher the MERV rating, the smaller the holes in the filter and the more particles it’ll catch. As a result, you’ll breathe cleaner and fresher air.


NATE stands for North American Technician Excellence, which is an independent organization that provides tests and certification for HVAC service technicians. Anytime you work with an HVAC contractor, ensure that they’re NATE certified.

You don’t have to respond to your HVAC service technician with a blank stare and an empty nod any longer. To improve the AFUE of your HVAC system with a NATE-certified service technician, call Aircom at 727-213-8190.
