Vacation Utility Checklist: Reduce Empty-Home Energy Use Without Creating Risk

An empty home does not have zero utility needs. Refrigerators, security systems, internet equipment, sump pumps, well equipment, freeze protection, humidity control, smoke and carbon-monoxide alarms, and medical or accessibility devices may need to remain active. The objective before travel is not to switch off everything; it is to distinguish essential loads from avoidable loads and prepare each system safely.

Start with a critical-load inventory

Walk through the home and list equipment that operates automatically. Mark each item as essential, optional, or uncertain. If uncertain, consult the manufacturer, service professional, insurer, property manager, or responsible household member. Never disable life-safety equipment to save electricity.

HVAC settings during travel

A thermostat setback can reduce heating or cooling demand, but the appropriate setting depends on climate, plumbing location, humidity, building materials, pets, plants, and vulnerable equipment. In cold weather, turning heat off can risk frozen pipes and property damage. In hot humid climates, eliminating cooling or dehumidification can encourage moisture problems.

Use a programmed vacation or hold mode supported by the thermostat and HVAC system. Avoid changes that disable equipment staging, heat-pump controls, freeze protection, or humidity management. Test remote monitoring and alerts before departure rather than assuming an app will remain connected.

Water and leak preparation

Inspect visible supply lines, toilets, faucets, water-heater areas, and automatic appliances. A leak that would be noticed immediately while occupied can run for days in an empty home. Some owners close the main water valve, but that decision must account for fire sprinklers, boilers, hydronic heat, ice makers, water treatment, irrigation, sump systems, and other equipment. Use a qualified professional when system interactions are unclear.

Smart leak detectors and automatic shutoff devices may reduce risk, but they require correct installation, power, connectivity, maintenance, and testing. They are not substitutes for repairing known defects.

Water-heater vacation modes

Many water heaters provide a vacation setting or manufacturer-approved setback procedure. Do not improvise by disconnecting power or fuel without understanding freeze protection, ignition, recirculation, sanitation, and restart requirements. Follow the exact manual for the equipment.

For a simple energy estimate, compare normal daily water-heating kWh or therms with measured empty-home consumption. Tank losses continue even without hot-water draws, while tankless units may have controls or recirculation loads. Actual savings depend on equipment and settings.

Refrigerators and freezers

If food remains, maintain safe temperatures and leave necessary power on. Reduce unnecessary door openings before departure, confirm doors seal, and avoid changing settings beyond manufacturer guidance. A nearly empty refrigerator does not automatically need to be unplugged.

If an appliance will be emptied and shut down for a long period, follow the manufacturer’s cleaning, defrosting, drying, and door-position instructions to avoid water damage, odor, or mold. Never leave perishable food in an unpowered appliance.

Electronics and standby loads

Identify devices that serve no purpose while the home is empty: unused entertainment equipment, printers, chargers, decorative lighting, and small appliances. Shut them down using manufacturer procedures. Leave equipment required for alarms, cameras, remote HVAC control, leak monitoring, backups, or communications.

Lighting and security

Continuous lighting wastes energy and can signal that a home is empty. If lighting is part of a security plan, use safe listed controls, varied schedules, and efficient lamps compatible with fixtures and timers. Exterior safety lighting, cameras, and alarms should be coordinated as a system.

Create an empty-home utility baseline

Record electric, gas, and water meter readings shortly before leaving when safely accessible. Utility portals may provide daily or interval data. During a future trip of similar length and season, compare daily use. Unexpected continuous water use can indicate leakage; high electricity may indicate HVAC, pumps, water heating, or equipment that remained active.

Do not assume remote data is perfect. Communication delays, estimated meter readings, and device failures occur. Arrange a trusted local contact for long absences, especially where storms, freezes, heat, sump pumps, or other property risks are significant.

Departure checklist

1. Confirm critical loads and emergency contacts.
2. Set HVAC using a safe, tested vacation strategy.
3. Inspect for visible water leaks and follow an approved water plan.
4. Configure the water heater according to its manual.
5. Protect refrigerated food or properly shut down empty appliances.
6. Turn off nonessential plug loads using safe shutdown procedures.
7. Test alarms, security, leak alerts, and remote connectivity.
8. Record meter readings and photograph settings for reference.
9. Provide a local contact with access and equipment information.

Frequently asked questions

Should I turn off the main breaker while traveling?

Generally not without a system-specific plan. It may disable refrigeration, HVAC, pumps, alarms, security, networking, and safety devices. Consult qualified professionals for long-term shutdowns.

How much electricity should an empty home use?

There is no universal number. Climate control, refrigeration, pumps, security, building size, and season dominate. Establish your own daily baseline and investigate unexpected changes.

Can I shut off water to prevent leaks?

Sometimes, but water may support fire sprinklers, boilers, hydronic heat, irrigation, appliances, or other systems. Follow local requirements and professional guidance.
