cost to run the evaporative cooler in summer
The evap has been running ~24/7 the past 1.5 months, keeping the interior at ≤78° F when ambients have been up to 108° F. The first electric bill at this run duration is ~$100 more than in deep winter. So running ceiling fans and the central evap cooler (and increased fridge running cycle %) adds that much to the cost.
