You adjust your thermostat to a comfortable temperature, then notice a “Hold” button or setting you’ve never used. This feature can save energy and improve comfort, but only if you understand when and how to activate it.
This guide explains what the hold function does, when you should use it, how it affects your heating and cooling schedule, and how to make the most of this often-overlooked thermostat feature.
What Does Hold Mean on a Thermostat?
The hold function on a thermostat temporarily or permanently overrides your programmed temperature schedule, maintaining your current temperature setting until you manually cancel it or until a specified time. When you activate hold, the thermostat ignores scheduled temperature changes and keeps your home at the set temperature regardless of what time of day it is or what your normal program dictates.
How the Hold Function Works
Most programmable and smart thermostats run on schedules that change temperature throughout the day. You might program lower temperatures while you’re at work and warmer settings when you’re home.
When you press the hold button, you’re telling the thermostat to maintain the current temperature instead of following that pre-set schedule. The system will continue heating or cooling to keep your home at that exact setting until you release the hold or it expires.
Temporary Hold vs. Permanent Hold
Many thermostats offer two types of hold settings. A temporary hold maintains your chosen temperature until the next scheduled program change, which might be in a few hours when your schedule transitions from “away” to “home” mode.
A permanent hold keeps the temperature steady indefinitely, ignoring all scheduled changes until you manually cancel the hold. Some thermostats label permanent hold as “hold until I change” or simply “hold.”
Vacation Hold
Some advanced thermostats include a vacation hold option. This setting lets you specify both a temperature and a return date, keeping your home at an energy-saving setting while you’re away and resuming your normal schedule automatically when you return.
Common Reasons to Use the Hold Feature
The hold function serves several practical purposes in daily home temperature management. Understanding when to activate it helps you balance comfort with energy efficiency.
Schedule Disruptions
When you work from home unexpectedly, the hold function prevents your thermostat from switching to its energy-saving “away” mode. You stay comfortable without reprogramming your entire weekly schedule.
Similarly, if you’re home sick or your plans change, activating hold keeps the temperature where you need it. Once your routine returns to normal, you can release the hold and resume your regular programming.
Seasonal Transitions
During mild spring or fall weather, you might not need heating or cooling at scheduled times. Rather than constantly adjusting your program, you can set a comfortable temperature and activate hold.
This approach works well when outdoor temperatures fluctuate unpredictably. You maintain indoor comfort without the thermostat cycling on and off based on a schedule designed for different weather.
Guest Comfort
When hosting overnight guests, their comfort needs might differ from your usual schedule. Using hold lets you maintain a consistent temperature in guest areas without affecting your long-term programming.
After guests leave, you simply cancel the hold to return to your energy-saving schedule. This flexibility beats creating a temporary program you’ll need to delete later.
Equipment Testing
If you’re troubleshooting heating or cooling performance, hold mode helps you test your system. By maintaining a constant temperature setting, you can observe how long your equipment runs and whether it reaches the target temperature.
This diagnostic approach removes the variable of scheduled changes, making it easier to identify potential problems with your HVAC system.
When Not to Use Hold
While convenient, leaving your thermostat on permanent hold defeats the purpose of programmable temperature control. Your scheduled setbacks during sleep hours and when you’re away typically save 10 to 30 percent on heating and cooling costs.
If you find yourself constantly using hold because your schedule doesn’t match your programming, you should reprogram your thermostat instead. Most modern thermostats allow different schedules for weekdays and weekends, and some offer unique programming for each day.
Forgetting to Cancel Hold
The most common mistake is activating permanent hold and forgetting about it. Your system will continue running at that temperature setting indefinitely, potentially wasting significant energy.
If you must use hold, consider setting a reminder to check it later. Better yet, use temporary hold whenever possible so your schedule automatically resumes.
How to Activate and Cancel Hold on Different Thermostats
The exact process varies by thermostat model, but most follow similar patterns. Always consult your specific thermostat’s manual for precise instructions, as button sequences and menu options differ between manufacturers.
Basic Programmable Thermostats
On most basic programmable models, you’ll find a dedicated “Hold” button. Press it after adjusting your desired temperature, and the display should show “Hold” or a hold icon.
To cancel, press the “Run” or “Run Schedule” button, or press “Hold” again. Some models require pressing “Cancel” or returning to the main menu.
Touchscreen Thermostats
Touchscreen models typically display hold options when you adjust the temperature. You’ll see choices like “Hold Until Next Period,” “Hold Permanently,” or “Hold For 2 Hours.”
Select your preferred option by tapping it. To cancel, access the main screen and look for “Cancel Hold” or “Resume Schedule” options in the menu.
Smart Thermostats
Smart thermostats like Nest, Ecobee, and Honeywell Home offer hold features through both the physical device and mobile apps. In the app, you’ll typically find hold options under temperature settings or schedule overrides.
Many smart thermostats learn your preferences and may ask if you want to hold a temperature when you make manual adjustments. Some automatically create temporary holds that expire after a set period, usually two to four hours.
Understanding Your Thermostat Display During Hold
When hold is active, your thermostat display changes to indicate the override. Look for these common indicators to confirm hold is working.
Visual Indicators
Most thermostats show the word “Hold” prominently on the display. Some use abbreviations like “HLD” or icons such as a hand symbol or pause icon.
The display usually shows your current temperature alongside the hold temperature. Scheduled temperature changes typically disappear or gray out while hold is active.
Hold Duration Information
For temporary holds, the display often shows when the hold will end. You might see “Hold Until 6:00 PM” or “Hold Until Next Period.”
Permanent holds typically display “Hold” without a time limit, though some show “Hold Indefinitely” or use a specific icon. If you’re unsure whether your hold is temporary or permanent, check your thermostat manual.
Impact on Energy Efficiency
Using hold strategically can actually improve efficiency when your schedule changes temporarily. The key is remembering to release the hold when your normal routine resumes.
Holding your thermostat at a moderate temperature during a long weekend away uses less energy than letting it cycle through your normal work-week schedule. However, holding it at maximum comfort settings 24/7 will increase your utility bills significantly.
Smart Recovery and Hold
Some thermostats include smart recovery features that start heating or cooling early to reach your scheduled temperature at the programmed time. When hold is active, smart recovery typically stops working since the schedule is overridden.
This won’t affect efficiency negatively if you’re using hold appropriately. Just be aware that when you cancel hold, it may take longer than usual to reach your next scheduled temperature if smart recovery needs time to recalibrate.
Troubleshooting Hold Function Issues
If your hold function isn’t working as expected, several common issues might be the cause. Most can be resolved without professional help.
Hold Won’t Activate
If pressing the hold button has no effect, check whether your thermostat is in the correct mode. Some models require you to be in heating or cooling mode rather than “Off” before hold will work.
Low batteries can also prevent hold from activating on battery-powered thermostats. Replace the batteries and try again.
Hold Cancels Itself
Unexpected power interruptions can reset some thermostats, canceling active holds. If this happens frequently, you may have loose wiring connections that a qualified HVAC technician should inspect.
On smart thermostats, software updates sometimes interrupt hold settings. Check your thermostat’s app for notifications about recent updates or changes.
Schedule Won’t Resume After Canceling Hold
After canceling hold, your thermostat should return to following its programmed schedule. If it doesn’t, the schedule itself may have been accidentally deleted or corrupted.
Access your programming menu to verify that your schedule still exists. You may need to reprogram it if the settings were lost.
Advanced Hold Features
Modern thermostats offer sophisticated hold options beyond basic temperature override. These features give you finer control over your home’s climate.
Circulate Mode Hold
Some thermostats let you hold the fan in circulate mode, running the air handler periodically without heating or cooling. This improves air distribution and can reduce hot or cold spots in your home.
This feature works independently of temperature hold and is particularly useful in multi-story homes or during shoulder seasons when you need air movement but not temperature control.
Humidity-Based Holds
Advanced thermostats with humidity sensors can hold based on humidity levels rather than just temperature. You might set a hold that maintains 45 percent relative humidity, allowing temperature to vary within a comfortable range.
This approach works well in climates where humidity control matters as much as temperature. Not all thermostats offer this feature, so check your model’s specifications.
Hold Function and Multi-Zone Systems
In homes with zoned heating and cooling, hold functions typically work independently for each zone. You can hold the temperature in your home office during work hours while allowing other zones to follow their normal schedules.
Check your zone control panel to see which zones have active holds. Managing holds across multiple zones requires more attention but offers excellent flexibility and potential energy savings.
Making Hold Work for Your Household
The hold function serves you best when you understand it as a temporary override tool rather than a default setting. Use it for schedule disruptions, then return to your programmed settings.
If you’re frequently activating hold, take time to reprogram your thermostat to better match your actual routine. Most people’s schedules change seasonally, so reviewing your programming every few months helps maintain both comfort and efficiency.
Start by identifying when you most often use hold and why. If you hold every Saturday because you sleep later on weekends, program a different weekend schedule instead. If you hold during particular months, create seasonal programs that account for changing daylight and weather patterns.
Understanding what hold means on your thermostat helps you use this feature effectively to balance comfort, convenience, and energy savings. Whether you need a temporary override for an unexpected day at home or want to maintain consistent temperature during a special event, the hold function gives you control when your normal schedule doesn’t fit your needs.
