Yes, heat pumps require regular maintenance for effective operation. Regular upkeep is necessary to ensure they function optimally. If the heat pump is used frequently, its filter should be replaced about once a month, or every three months if used less frequently. Keeping fans and coils clean and free from debris is vital for maintaining efficiency and prolonging the life of the unit. Additionally, professional inspections are recommended twice a year, ideally before the heating and cooling seasons begin. Due to the complexity of heat pumps and the potentially hazardous chemicals they contain, most maintenance and repair work should be handled by professionals. This keeps the unit, your home, and your family safe and guarantees that the unit is maintained correctly for efficient and reliable operation.
