Mountain Top Air & Refrigeration | Experienced HVAC Repair in Claremont, NH

In Claremont's climate, heat pumps can freeze due to low refrigerant, blocked airflow, or a malfunctioning defrost cycle. If you see significant ice on the outdoor unit, first check that air filters and vents are clear. Then, turn the system to 'emergency heat' mode to prevent further damage and call us immediately. We'll diagnose the root cause—often a refrigerant leak or sensor issue—and perform the necessary repair to restore safe, efficient operation.

Yes, ice buildup is a sign of a problem, like low refrigerant or poor airflow, and can lead to serious damage. The ice itself can strain and bend coils, while the underlying issue forces the compressor to overwork, potentially leading to a costly failure. For Claremont homeowners, addressing ice promptly is key. We provide thorough diagnostics to fix the cause and prevent long-term damage to your system.

Proactive maintenance is your best defense. We recommend a pre-winter tune-up where we check refrigerant levels, test the defrost controls, clean coils, and ensure proper airflow. For Claremont residents, also keep snow and debris cleared from around your outdoor unit and change indoor air filters regularly. This preventative care helps your system run efficiently and reliably through the coldest months.
