What typically needs to be done
- Freeze preparation focuses on anything that contains water outside conditioned space: hoses, exterior faucets, irrigation/backflow equipment, evaporative coolers, condensate/drain lines and exposed plumbing.
- The heating system is confirmed operational, exterior intake/exhaust openings are kept clear and occupants know where the main water shutoff is located.
- Property-specific vulnerable pipes or equipment are handled according to their manuals/installations rather than using one universal freeze procedure.
What you can check or prepare yourself
- Disconnect garden hoses and drain/store them before a hard freeze.
- Review which exterior faucets are frost-free versus which have interior shutoffs/drains and follow the home-specific setup.
- Keep the thermostat/heating system operating normally and check rooms with plumbing on exterior walls for unusual cold spots.
- Never use an open flame or unattended space heater to thaw or protect pipes.
Step-by-step reminder
- Disconnect garden hoses from exterior faucets.
- Review manufacturer instructions for exterior plumbing, irrigation, condensate drains and other equipment that can hold water.
- Confirm the heating system is operating normally and exterior intake or exhaust openings are clear.
- Know where the main water shutoff is located before a freeze arrives.
Do not use open flames or unsafe heating devices to thaw plumbing. If a pipe freezes or bursts, follow utility guidance and contact a qualified professional when needed.
Before you start
Review the manual for the exact appliance, system or material in your home before opening panels, disconnecting utilities, changing settings or using chemicals. Model-specific procedures and local installation details can differ from a general guide. Shut off power, water or fuel only when the manufacturer procedure calls for it and you are comfortable identifying the correct control. Stop if the condition you find is different from what is described here.
When to bring in a professional
The homeowner checks above can help you understand the condition of the system and prepare for service, but the higher-risk portion may require specialized tools, safe access, combustion/electrical knowledge, refrigerant work, pressure equipment or a qualified inspection. Use the typical-work list to understand what a proper service visit should cover, and hire the appropriate professional for work outside normal homeowner access.
This guide is general information, not a home inspection or a guarantee that a procedure is suitable for your specific equipment or conditions. Follow manufacturer instructions and applicable codes, stop if anything appears unsafe or different from the guide, and use a qualified professional when appropriate.
