9 Tips to Prepare Your System Before Leaving for Vacation: HVAC Settings Guide

Smart HVAC Configuration Tips for an Empty Home

Planning a vacation or work trip? While you’re away enjoying a change of scenery, your home still needs a little attention—especially your HVAC system. The right HVAC settings can protect your property, improve energy efficiency, and ensure you return to a fresh, comfortable space.

In this blog, we’ll share practical HVAC configuration tips for homeowners who leave their homes unoccupied for several days or weeks. A few smart adjustments can prevent costly issues and help you save on utility bills while you're away.

1. Adjust the Thermostat, Don’t Turn Off the System

It might be tempting to shut off your HVAC system completely to save energy, but that can backfire. Extreme indoor temperatures can damage electronics, wood furniture, floors, and even cause pipe problems.

Recommended Settings:

• Summer: Set thermostat to 80–85°F (26–29°C)

• Winter: Set thermostat to 55–60°F (13–16°C)

This keeps the temperature stable enough to protect your home while using minimal energy.

2. Enable Vacation Mode or Smart Schedules

If you have a smart thermostat, activate “vacation mode” or create a custom schedule before you leave. These modes automatically reduce energy usage while maintaining safe indoor conditions.

Bonus:

Receive remote alerts if indoor temperatures or humidity stray from your set range.

3. Set Humidity Control Between 30–50%

Balanced humidity prevents mold, wood warping, and uncomfortable air. If your HVAC system includes humidity control, set it to maintain levels between 30%–50% before leaving.

Extra Tip:

In very humid or dry climates, consider integrating a dehumidifier or humidifier that runs independently with your HVAC.

4. Clean or Check the Air Filter

A clean filter ensures your system runs efficiently and prevents dust buildup while you're gone. Before traveling, inspect and replace the HVAC air filter if needed.

This keeps air circulating properly and reduces stress on the system during your absence.

5. Close Curtains and Blinds

Limit heat gain in summer and heat loss in winter by closing curtains, especially on south-facing windows. This helps your HVAC maintain temperature more efficiently while you’re away.

6. Seal Doors, Windows, and Vents

Do a quick inspection for air leaks around doors and windows. Use weatherstripping or caulk to seal any gaps. Also, ensure no furniture or objects are blocking vents.

Result:

Better temperature retention and reduced HVAC workload.

7. Turn Off Unnecessary Systems, Not HVAC

While you can unplug electronics and water heaters, keep your HVAC system on and adjusted. It’s designed to protect your indoor environment—even when you’re not home.

8. Enable Air Circulation Settings

If your system has a fan-only or air circulation mode, set it to run periodically. This helps prevent musty odors, stale air, and stagnant humidity.

9. Schedule a Maintenance Check Before You Leave

Prevent unpleasant surprises by booking a pre-trip HVAC inspection. A professional can ensure your system is leak-free, calibrated, and ready to operate safely during your trip.
