Common warning signs include reduced heating or cooling performance, ice buildup on the outdoor unit, strange noises like grinding or squealing, the system running constantly without reaching temperature, blowing cold air in heating mode, unusual odors, or rising energy bills. If you notice any of these symptoms, your heat pump needs professional attention. Bi-annual service is recommended to ensure efficient operation, prevent breakdowns, and catch issues before they become expensive repairs.

Heat pumps should receive professional service twice per year—once in spring before cooling season and once in fall before heating season. Bi-annual service ensures efficient operation in both modes, prevents seasonal breakdowns, maintains warranty coverage, and extends equipment lifespan. Between professional visits, homeowners should clean or replace filters monthly, keep outdoor units clear of debris and snow, and monitor for unusual noises or performance issues.

Common causes include low refrigerant levels from leaks, dirty air filters restricting airflow, faulty defrost controls that can't melt ice buildup, a malfunctioning reversing valve stuck in cooling mode, blocked outdoor coils, or sensor failures. Sometimes the outdoor unit freezes during normal defrost cycles in cold weather. While changing filters is simple, most freezing and heating issues require professional diagnosis to check refrigerant levels, test defrost operation, and verify reversing valve function. Our technicians can quickly restore proper heating performance.
