Winter is here, and with it comes the challenge of keeping our homes warm and comfortable. If you’ve ever felt like your heat pump just can’t keep up with the cold, you’re not alone. Many homeowners misunderstand the defrost mode, seeing it as a problem rather than the essential function. 

Why Does My Heat Pump Need a Defrost Mode?

Imagine waking up to a freezing home because your heat pump can’t handle the cold. That’s a nightmare for anyone! The defrost mode activates when outdoor temperatures drop significantly, causing moisture in the air to freeze on the outdoor unit’s heat exchanger. Without this mode, ice would build up, reducing airflow and efficiency, and potentially damaging your unit. So, instead of seeing the defrost cycle as a hassle, view it as your heat pumps self-care routine.

Signs Your Heat Pump is in Defrost Mode

You might panic when your heat pump stops heating momentarily, but this is a normal part of the defrost cycle. Here’s what to look for:

• Indoor and outdoor fans will pause.
• The compressor continues running, often louder than usual.
• Steam or “smoke” from the outdoor unit (this is just steam, not smoke).

These signs indicate that your heat pump unit is working to melt the ice and restore optimal performance.

Tips to Keep Your Home Warm During the Defrost Cycle

Feeling the chill when your heat pump goes into defrost mode? Here’s how to stay cozy:

• Set Timers: Program your heat pump to start heating an hour or two before you wake up or return home.
• Night Settings: Run your heat pump at a lower temperature (18-19°C) overnight to maintain warmth without overloading the system.
• Regular Maintenance: Clean your heat pump filters and ensure the outdoor unit is clear of debris to reduce the frequency of defrost cycles.
