As autumn settles in and the nights start to feel cooler, many households begin to rely on their heating systems again. For those with a modern air-to-water heat pump, this is the perfect moment to check performance, fine-tune settings, and prepare for the coming winter. Taking a few small steps now can ensure comfort, reduce bills, and extend your unit’s lifespan.
Why autumn is the best time for a heat pump check
Autumn is a transition season: your heat pump may still switch between cooling and heating modes. This makes it the right time to make adjustments before the system has to work harder during winter. By carrying out basic maintenance, you set the stage for optimal efficiency and consistent heat pump energy savings.

5 simple tips for autumn heat pump maintenance
- Check and clean air filters
Dust and pollen from summer can clog filters, reducing airflow. A clean filter helps the system work more efficiently and directly impacts heat pump energy savings. - Inspect the outdoor unit
Make sure leaves, branches, or other debris are cleared away. Good airflow around the outdoor unit prevents strain on the system and helps maintain top performance. - Review system settings
Autumn is an ideal moment to adjust your temperature schedule. Lowering the set temperature slightly can make a big difference in overall efficiency. - Activate frost protection mode
Many modern models, such as the Tongyi R290 series, include automatic frost protection. Ensure this feature is enabled so your system remains safe as outdoor temperatures drop. - Consider pairing with solar PV
Autumn still brings hours of sunlight in many regions. Connecting your heat pump with solar energy maximizes renewable use and increases long-term heat pump energy savings.

Common questions from users
“Will my heat pump work well in cold weather?”
Yes. Modern R290 air-to-water heat pumps are designed for efficient heating even in sub-zero conditions.
“Do I need professional servicing every year?”
We recommend at least one professional inspection before winter. This ensures refrigerant levels, sensors, and performance settings are all checked.
“Can I save money by adjusting my thermostat?”
Absolutely. Even reducing the set temperature by 1°C can deliver significant heat pump energy savings over the season.
“Should I turn off my heat pump when I’m away?”
Not necessary. Most models include holiday or eco modes that keep your home protected while minimizing energy use.
“What if I notice higher electricity bills in winter?”
That’s normal, since heating demand increases. Pairing your heat pump with solar panels or using smart controls can help balance costs and improve efficiency.
