Tech Tip from Cleghorn HVAC Services
During periods of extreme cold combined with wet conditions, heat pumps can develop frost or ice on the outdoor unit. This is common and doesn’t always indicate a system failure.
What you should know:
• Light frost is normal and should clear during the unit’s automatic defrost cycle.
• Heavy ice buildup—especially ice encasing the cabinet or coil—can restrict airflow and reduce heating performance.
• Some icing issues can be resolved without a service call, while others do require professional service.
Homeowner tips:
• Keep the outdoor unit clear of leaves, snow, and debris.
• Never chip, pry, or strike ice off the unit—this can cause costly damage.
• If the unit is fully iced over, struggling to heat, or running continuously, it’s time to call a professional.
If you’re unsure whether the icing you see is normal or a concern, Cleghorn HVAC Services is here to help. Addressing ice issues early can prevent damage and keep your system running efficiently.
Experience. Dependability. Integrity.
