A heat pump is a specially-designed all-in-one heating and cooling system. This appliance has the capability of moving the heat to the outdoor region of the home to cool the internal regions and the capability of moving heat from the outside region of the home in an effort to heat the internal regions. It is a refrigeration system that utilizes mechanical compression cycles that can be easily reversed, depending on environmental temperature needs.
In simple terms, it has the ability to transport heat from one area to another area, based on the season. A heat pump is a highly efficient unit for residential structures because it moves heat instead of generating it. Now that winter is in full swing, it is imperative to know when it is time to replace your heat pump. In this brief guide, we will expound on 5 signs that will help in making that determination.
Warning Signs of a Failing Heat Pump
Sign #1: Reduction in Air Flow
One of the first signs that you might notice when it comes to heat pump malfunction is the reduction in air flow. In many instances, the system’s filters may be at fault for this issue. In other instances, it could be a case of ductwork that is faulty. In several cases, though, the overall functionality of the system may be dwindling.
Before electing to completely replace the unit, you should contact a HVAC technician if you notice that the volume of air being pushed through your home is lower than normal. A repair may be what is needed; however, if a new system is necessary, the technician will be able to inform you of that and will be able to walk you through the process of setting up a new heat pump system that is appropriate for your home.
Sign #2: Reduction in Heating Capacity
Perhaps the air flow seems to be normal, but, the air that is being transported from the system into your home may seem a bit too cool for the winter months. If this is the case, your heat pump is exhibiting a reduction in heating capacity. In many instances, the thermostat of the unit may be on the wrong setting; however, in most instances, this is a sign that the refrigerant in the unit is leaking or that the compressor is experiencing some type of complication.
While thermostat and refrigerant issues may typically be resolved quickly and with the assistance of a HVAC technician, compressor issues are indicative that a new heat pump needs to be installed.
Sign #3: Visible Signs of Icing on the Unit
Many mistakenly believe that the visible signs of icing on a heat pump are normal during the winter months. In all actuality, this indicates that there is an issue. While commonly a result of a clogged filter or a leakage of refrigerant, this could also be a result of a malfunctioning heat pump. If you witness icing, contact with a technician is required.
Sign #4: Inability to Change Between Modes
The fourth sign that could indicate it is time for a new heat pump is the system’s inability to switch from one mode to another mode. This issue commonly indicates that the reversing valve of the system is inoperable. When this occurs, the valve becomes completely stuck. In other cases, the problem could lie with the solenoid that is part of the device.
An HVAC technician will need to evaluate the system to make a proper diagnosis. Unfortunately, a case of a bad reversing valve and/or a bad solenoid could result in irreversible damage to the heat pump before the official discover of the issue, resulting in immense damage to the system.
Sign #5: Excessive Noise
The final sign that it may be time to replace a heat pump is the presence of noise – especially excessive noise. Heat pumps are designed to operate quietly. If you hear grinding noises, screeching noises, clicking noises, or any other unusual sounds being emitted from your heat pump, you should turn the system off and immediately contact a HVAC technician for assistance.
While several sources of noise may be easily identified and repaired, there are some cases where the cause of the noise indicates that the system – as a whole – is not only malfunctioning, but, losing its capability of functioning completely. If you notice noise, schedule an appointment with a heat pump technician as quickly as possible.
