How to Prepare Your HVAC System for Holiday Travel and Extended Absences

At The Lake Heating & Cooling LLC • December 17, 2025

The holiday season is a special time in Osage Beach, Lake Ozark, and the surrounding Missouri counties. Whether you’re planning to visit family out of state or escape the winter chill for warmer climates, it’s important not to overlook one crucial task before you pack your bags: preparing your HVAC system for your absence. At The Lake Heating & Cooling, we know that peace of mind while you’re away starts with a well-maintained, energy-efficient home.


Why Prepare Your HVAC System Before Extended Travel?


Many homeowners in Camden County, Miller County, and throughout the Lake region ask, “Should I turn off my heat or AC when I’m away for the holidays?” That’s a trending question every December, and it’s a smart one—especially when weather in mid-Missouri can turn cold and unpredictable. Preparing your HVAC system before you travel not only protects your property from winter hazards such as frozen pipes and inefficient heating, but it also helps you save on energy bills and avoid preventable repairs.


1. Set Your Thermostat for Energy Savings and Protection


As tempting as it may be to turn off your system entirely, it’s best to keep your HVAC running at a lower setting to prevent freezing temperatures inside your home. Smart and programmable thermostats allow you to set a minimum temperature—usually 55–60°F—which is ideal for preventing frozen pipes without wasting energy.


Tips for Setting Your Thermostat:


  • For traditional systems, set the temperature to 58°F.
  • If you have a smart thermostat, enable vacation or “away” modes.
  • Keep a steady temperature to prevent rapid fluctuations that stress your HVAC system and home’s structure.


2. Schedule a Professional HVAC Maintenance Check


Before you head out of Osage County, Pulaski County, or beyond, consider scheduling a professional inspection. A comprehensive HVAC check from At The Lake Heating & Cooling includes assessing system efficiency, confirming there are no leaks or electrical issues, and making sure filters are clean—all critical for uninterrupted operation while you’re away.


Benefits of Pre-Travel HVAC Maintenance:


Reduces the risk of emergency breakdowns

Ensures system efficiency, lowering utility costs

Provides peace of mind knowing your home is protected


3. Seal Up and Insulate for Winter Weather


Drafts and air leaks can quickly undo your thermostat settings, especially during cold Missouri nights. Take a few minutes to seal windows and doors and check for drafts in attics or basements. This not only boosts your HVAC’s effectiveness but also enhances overall home energy efficiency.


Quick Home Energy Prep List:


  • Check weatherstripping on all exterior doors
  • Seal gaps around windows with caulk or insulating tape
  • Close fireplace dampers and unused vents


4. Adjust Water Heaters and Plumbing


While not strictly HVAC, your water heater plays a major role in winter home safety. If you’re using a traditional tank or tankless water heater system, set it to “vacation” mode or lower the temperature to prevent energy waste. Consider having At The Lake Heating & Cooling inspect your water heater as part of a full home winter prep service.


What to Do If You Have a Geothermal or Advanced Heating System?


Homeowners in the Lake Ozark region with geothermal HVAC or heat pump systems should consult with qualified professionals about optimal settings for extended absences. Our team offers guidance tailored to your system type and local climate, ensuring year-round protection and efficiency.


5. Don’t Forget Indoor Air Quality and Security


Install high-quality air filters and consider an HVAC monitoring device. Smart home systems can alert you (or your HVAC contractor) if temperatures drop unexpectedly, helping you respond quickly before small issues become big repairs.

Your holiday plans should be stress-free. With a little preparation and a professional tune-up, you’ll return to a comfortable, well-protected home—no matter what Missouri’s winter brings.
