The situation with a dirty filter and weak airflow was identified thanks to a heating system check. Both issues were resolved right away. The heater is working with more power and is energy-saving.

I have used the internet to book my heater service and the service was good. His work was deep, meticulous and detailed and it astonished me. After that he checked that everything was fine and the system operated correctly and all functions were working well.
