All other things being equal, a higher SEER unit will cost more – about 8-10 percent for every 1-point increase in SEER. On average, it will take about 3 years to offset the cost of an 18 SEER unit vs. a 14 SEER unit (less if you use it more often). If you have the money now, investing in the higher SEER unit will pay off in the long run.

There are no shortcuts when it comes to evaluating cooling load – if someone gives you a simple calculation based on house volume alone, you won’t be getting the most out of your system. To find your best sizing match, you need the help of experienced professionals.
