Set your heat pump to a constant đđ °đ to đđ °đ when you are home, and avoid adjusting the temperature by more than 2 °F at a time. This steady approach prevents the system from activating costly auxiliary (backup) heating strips and maximizes overall energy efficiency.
For the most efficient winter operation, set your thermostat to a steady 68°F (20°C) while you are home. Unlike traditional furnaces, heat pumps work best when left alone rather than constantly adjusted. Avoid large temperature "setbacks" (lowering the temp drastically), as this forces the system to work harder to reheat the home.
We would normally recom- mend 18â22°C for a com- fortable environment, but if you prefer your home on the warmer side then we suggest the 22°C mark. Setting a higher temperature is not rec- ommended as the heat pump will work hard to achieve this temperature potentially increasing power usage.
The reality is that it's usually not a good idea to simply keep a heat pump operating all through the night while you're asleep. Instead, you should make sure that you have a programmable thermostat and set it to have it lower the indoor temperatures by 8° to 10°F when people are asleep.
To use a heat pump efficiently in the winter, set your thermostat to a comfortable, constant temperature and leave it alone. Heat pumps work by extracting warmth from the outside air, so avoiding drastic temperature adjustments prevents the system from overworking or turning to costly auxiliary heat.
Most heat pumps should complete about two to three cycles per hour, with ten to twenty minutes of downtime between each cycle. If you notice your system cycling too frequently or not enough, it could indicate an underlying issue that needs attention.
If your heat pump is unexpectedly expensive to run, the most common culprits are inefficient auxiliary/backup heat, high local electricity rates, or a system that isn't sized properly.
Outdoor Heat Pump Unit Freezing
One common problem is the outdoor unit freezing when temperatures drop too low. Ice buildup can obstruct airflow, reducing the unit's ability to capture heat. Most heat pumps have a defrost cycle to handle this, which usually solves the problem.
If you're not sure how long it takes, try turning the heating on about 30 minutes before you need it. You should turn it off 30 minutes before you'll stop needing it. You might need to turn on your heating earlier if your home takes longer to reach a comfortable temperature.
There are two entirely different HVAC concepts known as the "20-degree rule" for heat pumps. The first is a user guideline that suggests setting your thermostat no more than 20âF above or below the outdoor temperature. The second is an equipment metric referring to the system's "temperature split" or output efficiency.
Heat pumps begin to lose efficiency when outdoor temperatures drop below 40âF40 raised to the composed with power Fđđâđ . At this point, there is less ambient heat to extract from the air, requiring the system to work harder.
Morning: Start with dry mode to remove overnight moisture. Midday: Switch to cooling during peak heat. Evening: Return to dry mode for comfort without excess cooling. Night: Use sleep mode or gentle dry mode.
Heat pumps do not dehumidify while in heating mode. In fact, by raising the indoor temperature, heating lowers your relative humidity, making the air feel drier.
Is 72 a good temperature for heat in the winter? While slightly higher than the typical energy-saving range of 68°Fâ70°F, 72°F still offers a reasonable balance between comfort and efficiency.
When it's extremely cold outside, the temperature difference is large, which makes it harder for the heat pump to transfer heat effectively. As a result, the heat pump may have to work harder and use more energy to maintain a comfortable indoor temperature, which can reduce its overall efficiency.
Tips for How to Prevent a Frozen Heat Pump in Winter
Known for his practical tips, Lewis introduced the '4pm rule' which involves using curtains strategically to retain heat. He suggests opening curtains when the sun rises at around 8:30am to let in natural warmth, and closing them by 4pm to keep the heat inside.
In most homes, Heating and Cooling (HVAC) systems drive the highest energy costs, accounting for nearly 40% to 50% of your total electricity bill. Following these, the appliances that run up your bill the most include water heaters, refrigerators, and laundry machines.
Inadequate or inconsistent insulation, like air leaks, can create hot and cold spots throughout your house. If you've ever seen any of your home's insulation, it's probably what resides in your attic or crawl space.
The top heat pump brands vary based on your specific climate, budget, and system needs. Industry experts consistently rank Carrier, Bosch, Mitsubishi, Lennox, and Trane as the best overall choices for efficiency, reliability, and smart-home integration.
To get your heat pump warming again, first verify your thermostat is set to "Heat" (not cool or fan-only) and set the temperature to your desired level. Next, replace your air filter and check that nothing (like snow, leaves, or outdoor furniture) is blocking your outdoor unit.

Heat Pump Runtime: What to Expect
On average, a heat pump runs in cycles for about 2â3 hours per day. However, this can fluctuate based on the factors listed above. During extreme weather conditions, your system may run continuously to maintain a comfortable environment.
Your heating and cooling system is by far the biggest energy consumer in your home. Air conditioners, furnaces, and heat pump HVAC systems work hard to keep your home comfortable year-round, but they also account for almost half of your energy bill.
This is especially true if your house has a heat pump. Heat pumps are most efficient until temperatures fall below 30 degrees outside. Once the temps dip below that, heat pumps can't run as efficiently to keep up with the cold, and backup electricity often kicks on.
