Heat pumps are an efficient and effective temperature control solution that most people install and enjoy for years to come. The reliable heat pump units that Fonko supplies and instals need minimal maintenance – usually once per year is enough. So homeowners often benefit from the heating and cooling that they provide without worrying about them all too much. However, with all mechanical systems, occasionally failure can happen and if your heat pump isn’t working optimally, it may need a repair.
Common Issues with Heat Pumps
In Auckland, a common issue our customers face with their heat pump is the mismatch between the selected temperature setting and the air being blown out. It’s not uncommon for cold air to be delivered when warmth is expected, or vice versa. This problem tends to occur more frequently in older heat pump units. If you’re experiencing this issue, it’s important to have it addressed as soon as possible. A properly maintained heat pump should consistently provide the desired warm or cool air, so any deviation from this indicates a problem that needs attention.
If you have an older heat pump unit, you may have noticed that although it continues to blow out air at a consistent level, sometimes cool air will come out instead of warmth. If your unit completely stops producing warm air altogether, this could indicate low levels of refrigerant. On the other hand, if cool air is being produced when the unit is set for heating, this could be indicative of a more serious issue such as compressor damage. Here are five reasons your unit may need to be repaired.
Refrigerant Leaks
Heat pumps use refrigerant to transfer heat between the indoor and outdoor units. A refrigerant leak can lead to reduced heating or cooling capacity and decreased efficiency. If you notice a decrease in performance or hissing sounds near the unit, it could indicate a refrigerant leak.
Frozen Coils
In colder weather, heat pump coils can freeze due to condensation or other factors. This can lead to reduced airflow and heating or cooling capacity. Regular maintenance, such as cleaning or replacing air filters, can help prevent this issue.
Faulty Reversing Valve
The reversing valve is responsible for switching the heat pump between heating and cooling modes. If it becomes stuck or malfunctions, your heat pump may not switch modes properly, leading to inconsistent temperature control.
Electrical Issues
Like any electrical system, heat pumps can experience problems with wiring, relays, or other electrical components. Faulty wiring or electrical connections can lead to issues such as intermittent operation, tripped circuit breakers, or even system failure.
Compressor Problems
The compressor is a critical component of the heat pump that helps circulate the refrigerant and facilitate heat exchange. If the compressor fails, the heat pump won’t be able to heat or cool your home effectively. Compressor issues can be caused by electrical faults, mechanical wear and tear, or other factors.
Ideally, a well-maintained heat pump should consistently provide the desired air temperature throughout your home. However, inconsistent temperatures can indicate issues with your heat pump. If certain rooms have warm spots while others remain cold, it could be a sign that your heat pump is deteriorating. On the other hand, if your unit is producing cool or irregular air, it suggests that there may be obstructions in the filters, valves, condensation drains or coils which can impact its overall performance.
To put it simply, a properly functioning heat pump should supply warm air when you need it and cool air when necessary. If it fails to do so, this indicates a problem that won’t resolve itself automatically. To check what issue your heat pump has, call Fonko for a service and repair. If your heat pump has seen better days and repairing no longer seems cost-effective in the long run; we may advise considering purchasing a new unit as an investment worth considering. We will provide you with our honest opinion regarding this matter during our inspection of your heat pump unit. Contact us today to find out more.
