Late Winter, Early Spring: How to Stay Comfortable When Temperatures Can’t Make Up Their Mind

If you’ve lived through a late winter or early spring in our area, you know the struggle. One day it’s freezing in the morning and warm by afternoon. The next day feels like summer, followed immediately by another cold snap. These temperature swings can make it tricky to keep your home comfortable—and even trickier to decide whether you should be running your heat or your air conditioning.

At Turssler Service Co, we call this “shoulder season,” and it’s one of the most common times we get questions from homeowners. Here’s how to manage the ups and downs without wasting energy, money, or your patience.

Why Temperature Swings Are So Hard on Your System

During late winter and early spring, your HVAC system may switch back and forth between heating and cooling more often than usual. This can lead to:

  • Higher energy bills

  • Uneven temperatures throughout the house

  • Extra wear and tear on your equipment

  • That constant thermostat guessing game

The good news? A few smart adjustments can make a big difference.

Use Your Thermostat Strategically

This is the time of year when your thermostat really earns its keep.

If you have a programmable or smart thermostat:

  • Set wider temperature ranges so your system isn’t constantly turning on and off.

  • Avoid setting drastic temperature changes—slow and steady is more efficient.

  • Use scheduling to account for cooler nights and warmer afternoons.

If you’re manually adjusting:

  • Resist the urge to crank the heat in the morning or blast the AC in the afternoon.

  • Aim for comfort, not extremes—it helps both your system and your wallet.

Let the Weather Work for You

Spring air can be your best friend.

  • Open blinds and curtains during sunny days to let natural warmth in.

  • Close them at night to help keep the chill out.

  • On mild days, crack open windows instead of running the HVAC system.

Fresh air plus lower energy use is a win-win.

Don’t Forget About Your Air Filter

Shoulder season is often when filters get overlooked. A dirty filter restricts airflow, making it harder for your system to heat or cool efficiently.

  • Check your filter monthly

  • Replace it as needed (usually every 1–3 months)

  • Enjoy better airflow, better air quality, and better performance

Is It Time for a Tune-Up?

Late winter and early spring are ideal times for HVAC maintenance. A professional tune-up ensures:

  • Your heating system is wrapping up the season safely

  • Your AC is ready before the first real heat wave

  • Small issues are caught before they become expensive problems

Regular maintenance helps your system handle temperature swings without missing a beat.
