Precooling involves running air conditioning earlier in the day to maintain cooler indoor temperatures as outdoor heat rises. This strategy helps avoid high energy costs during peak hours, especially as utility companies increasingly adopt time-of-use pricing. The primary goal of precooling is to minimize air conditioning usage during late afternoon and evening, when electricity rates are highest. Smart thermostats can facilitate the scheduling of these temperature adjustments effectively, making precooling a beneficial approach to manage electricity costs during extreme heat.
Precooling is when you run your air conditioner earlier in the day, typically in the morning or early afternoon so that your house is already nice and cool before outdoor temperatures spike.
The main goal is to reduce or avoid running the AC during the late afternoon and early evening hours. Those are usually the hottest and most expensive times of the day for electricity.
More utility companies are switching to time-of-use pricing-meaning energy costs a lot more during peak hours.
Precooling has the potential to lower your cooling costs as long as you do it right.
