Πόσο καίει ένα κλιματιστικό με βάση το βαθμό απόδοσής του Seer στην ψύξη.
SEER rating should be the No. 1 factor when choosing an air conditioner. Higher SEER rated AC units can save you $1,000s over the next 10-20 years in electricity bill savings.
To see exactly much you can save by choosing an air conditioner with a higher SEER (above the federally mandated minimum of 14 SEER), you can use the SEER savings calculator below. First, however, let’s look at one example:
Example: We have two 3 ton (36,000 BTU) central air conditioners. One has a 14 SEER rating and the other has a 20 SEER rating. Let’s take into account the average natural electricity cost of $0.1319 per kWh, and 1000h of AC use per season.
How much more efficient is a 20 SEER vs 14 SEER?
Solution: 14 SEER rated AC unit is powered (average seasonal wattage) by 36,000 BTU / 14 SEER = 2,570W; running it for 1,000 hours will spend 2,570 kWh. Total 14 SEER electricity cost = 2,570 kWh * $0.1319 per kWh = $338,72/year.
20 SEER rated AC unit is powered by 36,000 BTU / 20 SEER = 1,800W; running it for 1,000 hours will spend 1,800 kWh. Total 20 SEER electricity cost = 1,800 kWh * $0.1319 per kWh = $237,24/year.
In short, 20 SEER AC unit is 43% more energy-efficient than 14 SEER AC unit. Here are the savings:
- Per 1 year: $101,48 electricity savings.
- Per 10 years: $1.014,80 electricity savings.
- Per 20 years: $2.029,6 electricity savings.
You save about 7% per 1 SEER on electricity costs.
