How to Balance Temperatures in the Fall

Atlantic Refrigeration • September 27, 2025

We rely on our HVAC systems to keep homes and businesses comfortable year-round. In the fall, temperatures tend to fluctuate throughout the day, and you might find yourself constantly running to and from the thermostat. Switching too frequently from heat to air conditioning wastes money and energy, but implementing these smart adjustments can help you stay comfortable.

Start With a Default Temperature

Most homes or businesses can benefit from a lower temperature thank you think. Aim for 68 to 70 degrees on average. When it’s hot out, the AC will kick in, but you may find that the heat doesn’t need to run as often when you keep this setting.


Setting a wider comfort range of 68 to 72 degrees can reduce energy consumption, lower costs and still ensure a comfortable temperature in your living space.

Use Natural Lighting and Ventilation

Sunlight can warm your home naturally, while opening the windows can help air circulate and prevent overheating. As temperatures naturally start to drop in the fall, embrace natural lighting and ventilation to maintain your home’s temperature without running the AC or heater all the time.

Avoid Using Auto Mode

Auto settings on your thermostat can cause your air conditioner or heater to kick on or off prematurely. You may also find that your system runs constantly, even when your home feels fine. Switch to manual operation this time of year to cut costs and gain greater control over your indoor temperature.

Prepare for Cooler Temperatures

Wearing layers and switching to thermal sheets, or simply adding an extra blanket to your bed, can make it much easier to stay warm without running the heat. Invest in cozy sweats and a hoodie to stay warm inside when the temperature drops a bit, so you don’t have to keep switching from AC to heat throughout the day.

Maintain Your System

A faulty HVAC or any other heating or cooling system can result in frequent temperature problems. Your home might feel imbalanced with some rooms being quick to heat and others feeling constantly drafty. Address these issues with a professional who can perform an inspection, make important repairs or adjustments, and ensure that your heating and cooling system installed properly for your home and lifestyle.

Consider a Humidifier

Dry air in the fall can make rooms feel colder than they really are. If you have this issue, try using a humidifier to add some moisture to the air, and see if it improves the temperature. Just be mindful of relative humidity levels because too much moisture can lead to mold growth.


If you notice inconsistent temperatures or a rising cost in utility bills, it may be time to schedule a service call with a licensed technician.
