But they ended up spending $175 later in winter to buy the backup electric heater, as the standard SEER 13 would not produce heat when the outside temperature goes below 15 deg. In short if you buy a high SEER AC unit, with inverter technology and in-built low ambient feature, you pay more today, but it is your cheaper option in the long run, as you save $20-$60 approximately every month on electrical bills. Plus they work lot better than your regular standard units with lot more advanced features. Remember higher the SEER is more energy efficient the unit is. At the same time if you are buying this for just a guest room or a game room or a spare room where it will be used occassionally, you don't have to overspend on big brands.
