The 7 HVAC Terms That’ll Save You Thousands
Have you ever bought a new appliance or HVAC system but aren’t too sure what on earth do terms like SEER and AFUE mean?
You’re not alone.
I used to feel the same way when I’d see the yellow papers on the new appliances…until I learned what they meant and how they work.
And the best part is that you can learn them, too.
These terms, although confusing at first, are some of the most helpful pieces of information that can help YOU save money in the long run. Just make sure that you take the time to understand what each of them mean before you shop around for a new system.
HVAC Term #1: HVAC – Heating, Ventilation, and Air Conditioning
Own an air conditioner or a furnace at home?
Then, what you have is called a HVAC unit or HVAC system.
According to Scott Heating’s website, he explains the primary functions of the typical HVAC unit best:
“The main parts of the HVAC system are a heating, a ventilation, and an air-conditioning unit. Furthermore, modern systems include an air filtration and cleaning element as well. Heating is most often done by a furnace or a boiler.”
Other common HVAC systems includes boilers, humidifiers, radiant floors, and swamp coolers, just to name a few.
HVAC Term #2: BTU – British Thermal Units
Aside from watts (W) and kilowatts (kW), you may occasionally bump into BTU, especially if you’ve imported your HVAC system from outside the USA.
HVAC Term #3: AFUE – Average Fuel Utilization Efficiency
Defined by Trane as “a gas furnace’s efficiency in converting fuel to energy”, the higher your AFUE rating is, the more you’ll save.
For example, if your appliance’s AFUE rating is 80, this means that 80% is used to efficiently heat up your home while 20% will escape as exhaust.
HVAC Term #4: SEER – Seasonal Energy Efficiency Ratio
You’ve probably seen this term a ton of times on those yellow Energy Star papers, but for it’s for a good reason: it measures your units’ cooling efficiency.
The SEER rating is determined by the Air Conditioning, Heating, and Refrigeration Institute by dividing the cooling output by the total electric energy input.
Just like AFUE, the higher the rating, the better it is for you and your home.
HVAC Term #5: HSPF – Heating Seasonal Performance Factor
This abbreviation refers to the measurement of heat during an entire heating system.
Just like SEER and AFUE, the higher the rating, the better efficiency your HVAC unit has.
HVAC Term #6: EER – Energy Efficiency Ratio
You may have noticed that EER is similar to SEER.
That’s because the EER is the older way to measure cooling efficiency.
The only difference between the two is that the EER is measured by a set outside air temperature, a set inside air temperature and a 50% relative humidity.
HVAC Term #7: MERV – Minimum Efficiency Reporting Value
Back in the day, the MERV was included on Energy Star approved appliances, but as time went by, it was soon replaced by SEER.
But if you do see a MERV rating, look for a high rate.
High rating = better efficiency.
Although it’s common sense to do your research before making purchases, unknown abbreviations can make anyone’s head hurt.
But here’s the thing: these terms are here to help make life easier for you.
By being an informed shopper, not only will you make better decisions, you’ll also save money in the long-run.
