Deciding the Best Time to Run Your Cooler

Every family has their own schedule. Between work, school, activities, and dinner, it’s important to maintain a comfortable temperature in your home. Especially during the summer months!

Knowing the best time of day to run your swamp cooler is the best way to maximize cooling power while saving money on your monthly energy bills. As New Mexico cooling experts for over three decades, TLC Plumbing is here to help you save on your summer cooling costs.

Early Morning

If you can make it to your thermostat when your alarm goes off (the first time), you can create a cool environment that can last throughout the day. Running the swamp cooler at time of day when it’s already cool outside guarantees that you’ll get colder air than when the sun is up and out.


Evaporative coolers can provide excellent cooling power during the mid-morning hours (before 10AM). If you are allergy prone, however, it may be a good idea to wait until the evening. Pollen counts are highest in the morning hours, which can affect the indoor air quality of your home.


While the sun is strongest between the hours of 10AM and 2PM, this does not necessarily make it the hottest part of the day. The temperature outside usually hits its peak in the afternoon, a few hours before the sun goes down. While you won’t get the same chilly air as running your swamp cooler in the morning, you can still enjoy cooling relief.


During the hottest part of the day, it is not ideal to run your swamp cooler. You will only be able to lower the temperature to a certain extent. But, if it is exceptionally hot outside, running the swamp cooler will be absolutely essential for comfort.


Evening hours are a great time to run the swamp cooler. You can optimize airflow for dinner-time comfort and relief. Open the bedroom window before you go to bed so your bedroom can be refreshing as you head to bed!


Instead of running your cooler during the day, you can try running your cooler at night to maximize cooling power. Running your cooler at night ensures that the air delivered will be colder and have less pollen.

The effectiveness of your swamp cooler depends on a number of factors, including the weather, the size of your unit, and the type of swamp cooler you use. While a standard swamp cooler can lower the temperature of outdoor air by 10-20 degrees, models like Breezair and Mastercool can lower the temperature further – up to 40 degrees lower.
