How to Determine an Air Conditioner's Efficiency:
The best way to determine the efficiency of the air conditioner is by checking the SEER rating.
Well, now you may ask yourself what the heck is this SEER?
How are you going to determine SEER on your own?
How to find out your air conditioner's efficiency based on SEER?
In that case, allow me to explain:
- Check SEER (Seasonal Energy Efficiency Ratio)
Understanding the term isn't quite difficult. SEER meaning is Seasonal Energy Efficiency Ratio You can figure it out yourself.
The SEER rating is usually determined with the indoor cooling ability of an AC unit divided by the used amount of watts (energy) per hour to maintain the temperature you have set.
The SEER rating ranges from score 10 and goes all the way up to 20 or even more. The thing is that the more the score, the better energy-saving will occur, and the electricity will get lesser.
Here, the indoor temperature stays the same while these cycles are running. What varies is the outdoor temperature from lower temperature to higher so that the air conditioner can provide real results.
- What SEER Does
Keep in mind about the SEER rating that it doesn't mean that your AC will constantly perform at this rate.
SEER ensures a better energy-saving, energy-efficiency performance at your door.
When you're about to compare the score with other brands, make sure the other brands also show the SEER rating. Then it'll be a head-to-head comparison and beneficial to find out the right AC for you.
