How to Adjust Your Heating and Cooling System for Fluctuating Temperatures

Most people look forward to spring because the warm temperatures herald the return of summer. Unfortunately, the transition isn’t always smooth. Depending on where your home is located, you may possibly have to endure some very chilly days intermingled with near-summer temperatures in the same week. This makes it challenging to manage your indoor climate.

The issue of fluctuating temperatures—where it’s cool one day and warm the next—may leave you at a loss about how to set the HVAC system. Should you keep the AC on all night or flip the thermostat mode over to heating for comfort the next morning? This seasonal challenge doesn’t have a single remedy. The answer to a comfortable, energy-efficient home is to use the right strategies until Mother Nature makes up her mind. Here are some indispensable tips and practices to adjust your HVAC system during changing temperatures this spring.

Use a Programmable or Smart Thermostat

Investing in a programmable or smart thermostat is one of the simplest steps you can make for your furnace and air conditioning system. In contrast to traditional thermostats that offer reduced control, programmable thermostats let you set your chosen temperatures based on your schedule and comfort desires. By doing this, you can save power while you’re out and about, with automatic recovery periods that resume a comfortable setting before you return home.

A smart thermostat is better yet. One standout feature is the ability to easily change between heating and cooling modes. This advanced functionality makes up-and-down temperatures much easier to manage. Smart thermostats that have this ability have a unique heat/cool mode that quickly switches from your furnace to your air conditioner when it detects indoor temperature shifts. This simply means that on a spring day that starts out cool and warms up throughout the day, your heating and cooling system can heat your home in the morning and cool it back down as the temperature rises, all by itself.

Find a Temperature Everybody is Comfortable With

Finding your family’s ideal comfort zone is difficult during times of temperature fluctuations. If at all possible, you should set a temperature in the high 60s on chilly days and high 70s on warmer days to achieve a balance between comfort and energy efficiency. Feel free to make changes throughout the day based on real-time temperature changes—or switch your smart thermostat to heat/cool mode and let it handle everything.

If the war over the thermostat rages even with your best efforts to keep everyone comfortable, it may be time to start thinking about home zoning. This system uses numerous thermostats and ductwork dampers to direct air where it’s needed most. Zoning is particularly beneficial in two-story homes and those with grand windows. You can use zoning to keep your entire house at a more consistent temperature or enable individuals to adjust the temperature in their area according to their comfort settings. As an example, Dad might want a cooler setting in the home office, and the baby may need a warm, cozy nursery to nap in. In any event, zoning is the answer.

Dress in Layers

Spring is all about jeans and a sweatshirt in the morning, followed by shorts and a tank top a few hours later. Dress in layers so it’s convenient to get more comfortable with an outfit change rather than having to make a thermostat adjustment. This raises your comfort and reduces your use of your home heating and cooling.

Open Up Windows and Run Fans

Take advantage of mild spring temperatures to help keep your home more comfortable. For instance, your furnace might run in the morning after a chilly night, and continue running throughout the day as the temperature increases outside. Or, you could warm your home naturally by opening the windows to let sunlight and a warm breeze into the building. When things heat up too much, close the windows and start up ceiling fans to create a wind chill effect. This may reduce the need for air conditioning.

Don’t Ignore HVAC Maintenance

Even if you run your HVAC system less in the spring, regular maintenance is still essential to avoid unexpected repair visits. Here’s how to keep your HVAC equipment running properly:

    • Examine the air filter monthly and change it when it looks dirty.
    • Make sure the condensate drain is clear of obstructions.
    • Dust the air registers and make sure they’re all open and not covered by furniture, rugs or appliances.
    • Hose down the outside AC unit, clear away any debris and cut back surrounding vegetation.
