Your evaporative cooling installation details
Your estimate sits within the typical range.
Evaporative cooling adds moisture and needs windows cracked open to work, so it performs poorly in humid coastal climates. In dry inland climates it is cheap and effective.
Evaporative cooling costs much less to run than refrigerated air conditioning because it only uses a fan and water pump, but it cannot cool below a certain point in humidity.
💰 Ways to save
- Install before summer, cooling installers are cheapest and most available in the cooler months.
- Size the unit to the house, an undersized unit runs flat out and still underperforms.
- In a dry climate, evaporative is far cheaper to buy and run than refrigerated ducted, match the system to your climate.
