Thermostat Settings You Should Know by Season

A thermostat regulates indoor temperature by aligning heating and cooling systems with the desired setting. When temperatures rise above or fall below the selected range, it signals the HVAC system to turn on. An air conditioning service provider can help facility managers and homeowners understand how indoor temperature preferences should shift as weather patterns change. Here are some thermostat settings you should know by season:

Spring Adjustments

Spring is a season of transition, and the weather outside is often unpredictable. Cold mornings could shift to warm afternoons. These unpredictable changes should be reflected in thermostat settings. Settings should maintain a stable indoor temperature without overloading the system. Setting your thermostat to a moderate temperature during the day prevents the need for frequent cooling or heating cycles. Programmed temperatures can be slightly reduced during the night to promote comfort and minimize strain on the unit. In homes equipped with programmable thermostats, scheduling features help manage daily outdoor temperature variations without requiring constant monitoring. 

Summer Settings

During the summer, the thermostat plays a key role in maintaining comfort. Summer settings are typically chosen to create cooler indoor conditions, especially during the hottest hours of the afternoon. Set your thermostat at a constant temperature that reflects average comfort without overcooling. For a 90-degree day, setting the thermostat to the upper 70s or lower 80s helps establish a comfortable indoor temperature without straining the air conditioning system. Settings that are too low may result in continuous system operation, which can lead to excessive wear on components or decreased energy efficiency. 

Many modern thermostats offer multiple control systems to promote energy efficiency. Some of these include:

• Fan control: These options enable steady airflow without continuous cooling, promoting regular air movement without requiring full system function. 
• Auto mode: “Auto mode” allows the system to turn on and off as needed. This prevents excessive use of the blower motor and helps maintain a consistent temperature while minimizing cycling. 
• Zoning: Zoning can be used in multi-level houses or those with high square footage. This enables specific areas to receive cooling based on occupancy or sunlight exposure. Upper floors that retain heat longer in the summer afternoons can be programmed to a different temperature than lower levels.

Fall Recommendations

In the fall, the weather can change quickly between warm afternoons and chilly mornings. This variability should be reflected in thermostat settings while preparing for consistent cold temperatures. Many systems can switch between cooling and heating during this time of year. Pre-programming your thermostat’s heating or cooling settings enables the system to adjust to temperature fluctuations automatically. This strategy promotes indoor comfort while accounting for natural warmth from sunlight and outdoor air. Some thermostats also have adaptive recovery features, which slowly raise the temperature before the scheduled time to confirm that the desired comfort level is reached at the appropriate hour.

Scheduling routine air conditioning service in the fall verifies that your system is prepared for winter. Technicians inspect the system’s key components, looking for signs of wear and tear that impact efficiency. They also review your thermostat to make sure it is calibrated correctly. If the thermostat is not calibrated, the actual indoor temperature may not align with the programmed setting. This can cause frequent cycling, reducing the system’s energy efficiency. 

Winter Settings

Winter typically requires a more consistent heating schedule to maintain a comfortable indoor environment and prevent cold-related issues. Thermostat settings should remain steady during the day, particularly in colder climates where outdoor temperatures remain low even during daylight hours. Reduced nighttime settings can be suitable, depending on the level of insulation and the house’s construction. Multi-stage heating thermostats are particularly useful during this season, as they activate different levels of heat output depending on the outdoor temperature.
