Durham Heat Pump Repair

A heat pump that won’t switch modes may have a faulty reversing valve, a malfunctioning thermostat, or an electrical issue. This component is responsible for changing the system’s operation between heating and cooling. A professional technician can diagnose the problem and repair or replace the faulty part to restore proper function.

If your heat pump is covered in ice or frost, it could be due to restricted airflow, low refrigerant levels, or a malfunctioning defrost cycle. Turning off the system and checking the air filter can help, but if the problem persists, professional service is needed. A technician will inspect the system, clean the coils, and ensure proper refrigerant levels to prevent future freezing.

A heat pump that runs nonstop may be struggling due to dirty filters, incorrect thermostat settings, or extreme outdoor temperatures. In colder weather, heat pumps naturally run longer, but if it never shuts off, there may be an efficiency issue. A professional can assess your system and make necessary adjustments to optimize performance.

If your heat pump is blowing cold air when it should be heating, it may have a thermostat issue, a refrigerant leak, or a malfunctioning compressor. Sometimes, the system may be in defrost mode, temporarily switching to cooling to melt ice buildup. A thorough inspection by an HVAC technician can identify the problem and restore warm airflow.

Yes, a clogged air filter restricts airflow, forcing the system to work harder and reducing efficiency. This can lead to overheating, freezing coils, and poor temperature control. Replacing or cleaning your filter regularly helps maintain proper airflow and prevents unnecessary strain on your heat pump.

Heat pumps naturally make some noise, but loud banging, grinding, or rattling sounds could indicate loose parts, a failing motor, or debris in the system. Squealing noises may signal a worn-out belt or bearing issue. Scheduling a professional inspection can help identify and fix the problem before it worsens.

Before scheduling a repair, check your thermostat settings, replace the air filter, and ensure the circuit breaker hasn’t tripped. Also, inspect the outdoor unit for any visible debris or ice buildup that could be affecting performance. If these basic steps don’t solve the issue, a technician can diagnose and repair the problem.

If your heat pump is over 10–15 years old and needs frequent repairs, replacing it may be more cost-effective in the long run. Newer models offer better efficiency, lower energy costs, and improved performance. A professional assessment can help determine if a repair is worthwhile or if an upgrade is the best option.
