When you’re researching new heating, ventilation, and air conditioning products, or HVAC products, for your home, it can often feel like you’re wading through a whirlpool of acronyms and initialisms. BTU, SEER, EER, AFUE. What does it all mean? You might wonder about the benefits of choosing an Energy Star® product or how Minimum Efficiency Reporting Value (MERV) is used to rank the efficiency of air filters.

What is Seer ?
Seer stands for Seasonal Energy efficiency

When you’re shopping for AC units, a Seasonal Energy Efficiency Ratio, SEER rating, helps you determine an air conditioner’s efficiency. The higher the unit’s SEER rating, the more energy-efficient it is. For a SEER definition, think about it like this: SEER is the ratio of cooling produced in BTUs divided by the watts of electricity used.

What are BTUs/hour?
Btu stands for British Thermal Unit.

If you’re wondering about the BTU meaning, it’s first helpful to know that BTU stands for British Thermal Unit. BTUs are used to measure energy in relation to heat. When it comes to your AC or heater, the BTU rating tells you how powerful your unit is. When you see 6,000 BTUs/hour, this means that a 6,000 BTU heater can produce 6,000 BTUs of energy over the course of an hour.

What Is Two-Stage Cooling?

Two-stage cooling means the air conditioner or heat pump has a compressor with two levels of operation: high for hot summer days and low for milder days. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatures.

what is MERV?

MERV stands for Minimum Efficiency Reporting Value. When researching MERV filter ratings, it helps to know that the smaller the holes in an air filter, the fewer particles that can pass through. So, the higher the MERV rating, the more efficient the filter.

what is EER?

The best EER definition to know is that EER is the ratio of cooling capacity to the power input (in watts). An air conditioner with a higher EER rating is more efficient.

what is ENERGY STAR® ?

ENERGY STAR® is a program of the U.S. Environmental Protection Agency (EPA) designed to help consumers and businesses save money by choosing energy-efficient products and technologies.

Preferred Refrigerant

R-410A was invented and patented by Allied Signal (now Honeywell) in 1991.[3] Other producers around the world have been licensed to manufacture and sell R-410A, but Honeywell continues to be the leader in capacity and sales.[4] R-410A was successfully commercialized in the air conditioning segment by a combined effort of Carrier Corporation, Emerson Climate Technologies, Inc., Copeland Scroll Compressors (a division of Emerson Electric Company), and Allied Signal. Carrier Corporation was the first company to introduce an R-410A-based residential air conditioning unit into the market in 1996 and holds the trademark "Puron".

Heat Pump
All-in-one Heating and Air Conditioning System

During warmer months, a heat pump works as a normal air conditioner. It extracts heat from inside the home and transfers it to the outdoor air. In colder weather, however, the process reverses—the unit collects heat from the outdoor air and transferring it inside your home.

What Is Two-Stage Heating?

Two-stage heating means the furnace has two levels of heat output: high for cold winter days and low for milder days. Since the low setting is adequate to meet household heating demands 80% of the time, a two-stage unit runs for longer periods and provides more even heat distribution.
