How to Get your Savings Results
The three slide bars are adjustable. Click on the right size/SEER or grab and slide the button to it.
- Set the AC Size using the sliding button
Size can be determined using the Model # on plate on the unit. An 18 in the model number means it is 1.5 tons. 24=2 tons, 30=tons, 36=3 tons, 42=4 tons and 60=5 tons. For example, the Lennox ML14SCI-036 is a 3-ton AC.
- Set the SEER of the old unit
SEER is more difficult to determine if you don’t know it. Typing the brand and model # into a search engine is your best bet.
- Choose the SEER of models you’re considering
You can raise or lower the new AC SEER bar to compare with the old AC SEER (e.g. 14 SEER vs 16 SEER) to see what your costs savings would be and whether it’s worth the extra cost! If the savings really add up, they will pay for the higher cost of the more efficient AC. If they don’t amount to much, then a very efficient AC might not be cost-effective.
