Should You Run Your Cooling System When It’s Cool Outside?
When the temperature outside hovers around the same level as your desired indoor temperature—or even cooler—it might seem unnecessary to run your cooling system. However, the decision isn’t always straightforward. In this blog, we aim to provide you with comprehensive insights into whether running your cooling system under these conditions is beneficial or detrimental.
Things to Consider
Potential Wear and Tear:
Running your air conditioning system when it’s much cooler outside could potentially cause unnecessary wear and tear. Air conditioning units are designed to work most efficiently within a specific range of outdoor temperatures. When used outside of these parameters, it can lead to increased stress on the components, reducing the system’s overall lifespan. However, running your air conditioning during cooler morning and/or evenings to manage humidity, for instance, is ok.
Possible Damage:
In some cases, running the cooling system in much cooler temperatures might exacerbate other issues going on with your air conditioning system, such as freezing of the evaporator coils. This can cause significant damage and lead to costly repairs. If your system is in good working order, you shouldn’t see any issues flare up.
Increased Energy Consumption:
Operating your cooling system when the outside temperature is low can be less energy-efficient. Your HVAC system might end up working harder than necessary, leading to increased energy consumption and higher utility bills. It’s often more efficient to take advantage of the naturally cooler air by opening windows and using fans to circulate air.
Humidity Control:
One reason to consider running your cooling system, even when it’s cooler outside, is humidity control. High humidity levels can make your home feel warmer than it actually is, leading to discomfort. Your air conditioning system can help dehumidify the air, maintaining a comfortable indoor environment.
Allergens and Air Quality:
Keeping your windows open to let in cooler air can sometimes introduce allergens and pollutants into your home. Running your HVAC system with a high-quality air filter can help maintain better indoor air quality by filtering out dust, pollen, and other allergens.
