Buying a new A/C unit isn’t something that most people do on a daily basis. Many people can go years before even thinking about it. They just let that old clunker on top of there house keep growling away, as long as it keeps them cool, they’re cool. So once that day comes that old beast dies and your tired of sleepless, sweaty nights with 5 fans blowing on you, that don’t really do anything but make you a bit less sweaty, most people are down right lost when it comes to shopping around. Maybe you have bought one before, but your still unsure of what it means. Well our experts here have broken it down:
SEER stand for Seasonal Energy Efficiency Ratio. Basically it is how well your unit can turn electricity into cold air or the ratio of cooling in BTU to energy consumed in watt hours. The higher the rating, the better it is! For instance, let’s look at the Gold 17 Air Conditioner from American Standard with 36,000 BTU/h and a 17 SEER rating:
36,000 BTU for 8 hours a day for 200 days would equal to 57,600,000 BTU a year.
With a SEER rating of 17, 57,600,000 BTU/year equals 3388235.29412 watt hours/year (57,600,000/17)
We can then break it down further:
36,000 BTU/h divided by 17 SEER comes out to ~ 2118w or 2.12Kw per hour
If you know your Kw cost of electricity (or go solar) then multiply that by your 2.12 and you get how much it would cost you per hour to run your A/C.
Cost per Kw * Kw per hour = hourly cost of unit.
According to Electricitylocal.com, the average cost per Kw in Bakersfield is 15.59 cents per Kw, so a 17 SEER unit would cost ~33 cents per hour.
In comparison, an A/C unit in 2006 had a minimum SEER rating of 13. A 36,000 BTU unit would cost ~ 43 cents per hour. Most homes have an even older system with a lower rating that is costing them a lot more in electricity and maintenance cost.
Like all technology A/C units become more efficient every year, which thankfully helps bring the cost of comfort down. Econo Air is proud to carry American Standard Heating and Cooling Units that offer the highest SEER ratings in the industry.
