Let’s set the record straight: it’s entirely normal for your outdoor heat pump to have a light layer of frost during winter. That’s because heat pumps are designed with a “defrost mode” to periodically clear away frost and ensure proper functioning. However, if it’s completely covered in ice for more than a couple of hours, it’s a sign that something is wrong and you may need heat pump repair.
Ice buildup on your heat pump can indicate several issues that require attention, such as:
- A malfunctioning defrost control
- A faulty reversing valve
- Low refrigerant levels
These heat pump problems can cause long-term damage if not addressed promptly. Below, we’ll explore these complications and explain how to repair a heat pump with these issues.

Problem #1: A Faulty Defrost Control
Your heat pump’s defrost control ensures that frost is melted away efficiently. If it’s not functioning correctly, frost can accumulate and turn into ice. Common causes of defrost control problems include:
- A bad defrost timer
- A faulty thermostat
- A damaged defrost display
Any of these issues can prevent your system from properly managing frost buildup.
Solution: Contact a heat pump repair expert to diagnose the issue. A professional will inspect the defrost timer, thermostat, and display for any malfunctions. They have the tools and expertise to repair or replace faulty components and get your heat pump back in working order.
For these types of heat pump repair services, trust a reliable heat pump repair company like Shafer Services Plus.
Problem #2: A Faulty or Sticking Reversing Valve
The reversing valve in your heat pump directs the flow of refrigerant. When your system enters defrost mode, the valve reverses the flow, allowing heat to melt any frost on the outdoor unit.
If the reversing valve is broken or sticking, your heat pump won’t be able to defrost itself. Over time, this leads to significant ice buildup and potentially costly repairs.
Solution: A professional heat pump repair expert will inspect the reversing valve to determine whether it’s sticking or damaged. Depending on the severity of the issue, they may repair the valve or replace it entirely. For comprehensive heat pump problems and repair solutions, it’s best to rely on professional heat pump repair services.
Problem #3: Low Refrigerant Levels
Your heat pump relies on refrigerant to transfer heat. If the refrigerant level drops due to a leak, the temperature and pressure within the system decrease, causing frost and eventually ice to form on the refrigerant lines. Left unchecked, this problem can lead to severe damage.
Keep in mind that refrigerant operates in a closed loop and shouldn’t need to be replenished under normal conditions. Low refrigerant levels always point to a leak somewhere in the system.
Solution: A professional heat pump repair service will inspect your system to locate and fix the leak. Once the repair is complete, they’ll recharge your system with the proper amount of refrigerant, ensuring optimal performance. This type of ductless heat pump repair should only be performed by an experienced technician.
