Don't be confused, just drop everything to the right of the decimal and round to as your Kwh consumption or, the number of watts consumed per hour. You'll be very, very close. Let's fast forward to the annual operating cost for each of the following using the same 3 ton air conditioning system:.
You now want to determine the one and only one SEER rating that is right for you. How long do you plan on owning and operating the system, or how long will you live in the home the system is purchased for? This is the absolute key to your decision because the shorter your ownership period the greater your total cost will be due to a shorter amortization time of the purchase price the fewer years you can spread the purchase price over before you no longer receive any operational benefits.
Unfortunately, from my years in the field, this is almost never brought into the equation. The time value of money is defined as the opportunity value of other investments missed because of your increased investment in a SEER rating higher than Let's assume your system is broken and you need a new one. We know that 14 SEER is the "floor" pricing because, assuming you shopped around, 14 SEER will be the lowest price you are offered as it the federal minimum in terms of efficiency, hence it is the base or floor pricing.
We don't need to calculate the return on the 14 SEER because you have no incremental increase in investment because it is your "floor" pricing - everything else is compared to the 14 SEER to determine if the increased price will pay itself back to you.
Remember, your system is broken and you need it replaced so 14 SEER is the choice everything else is compared to, hence the "incremental" increases are the price differences associated with any given higher SEER system as compared to the 14 SEER system Just the difference, not the total price.
This is a trick of the trade that you want to avoid at all costs if you have to replace your air conditioner anyway. No fun for you at all. I asked you earlier about your expected ownership period and that is the next variable in our search for true value. Let's use 5 years because that is the number most quoted when homeowners are asked how many more years they plan to live in their current residence.
This is the base number you are trying to determine whether or not will be returned to you from the annual operating cost reduction achieved by the 2 point increase in SEER rating. SEER is the rating system representing the energy efficiency of air conditioners and heat pumps.
It stands for Seasonal Energy Efficiency Ratio. The higher the number, the less electricity the air conditioner or heat pump consumes. This is expressed in watt-hours Wh. SEER is also calculated based on indoor and outdoor temperature. Naturally, the outdoor temperature during a typical cooling season is not constant. It varies based on weather and climate. This applies to the temperature of the return air, not the supply air. It simple terms, it can either cool your home by transferring warm air from the inside of your home to the outside, or it can heat your home by transferring warm air from the outside, inside.
