Heat pumps are a modern-day wonder that provides cost-effective and green heating and cooling. Those of us who are conscious of our environmental responsibility now have a viable option to heat and cool our homes in an environmentally friendly manner. Like all appliances, heat pumps may act up from time to time. This does not mean they are not a sound system or a bad investment. It just means that some repairs are in order.
Some heat pump problems are common, and others are rare. Today, we aim to enlighten you on the four common heat pump issues and how to troubleshoot them.
Four Common Heat Pump Issues And How To Troubleshoot Them
First of all, there is one thing that everyone should know about heat pumps – These heating and cooling systems are not meant for areas with extreme weather patterns. They serve best in those areas where the weather is moderate.
Now let us talk about the associated issues. If the heat pump is not working properly, it does not mean the unit has done what it could and has now given up. There is no need to panic, for most probably, the reason is well within your purview of handling. In no specific order, these are the common problems heat pump owners may have to face:
1. Heat Pump Is Not Cooling Properly – You need to check the following:
a) Thermostat Issues – The first problem could be that the thermostat has run out of batteries and cannot communicate with the heat pump. In this case, you will have to replace the old batteries with new ones. The other thing could be that you have not set the thermostat to “Cool”; therefore, it is not cooling. Once the setting is corrected, cooling will also start. Apart from that, it might be an electrical issue. If that is indeed so, only a technician can help.
b) Dirty Components – If dust or dirt deposits on critical components of the heat pump, it may affect cooling. So if you feel the air entering the home is warm, it’s best to give the heat pump a good cleaning. Do check the condition of the air filters also. If found dirty, replace them with clean ones.
c) Low Refrigerant – If the refrigerant level has fallen below the minimum mark, it will not cool. There’s nothing you can do about it yourself. Call the HVAC technician. He will plug the source of the leak and top up the refrigerant.
d) Reversing Valve Is Broken – When the heat pump runs and the air entering the home is warm, the reversing valve may be broken. If it is, the HVAC technician will have to come and change it.
2. Heat Pump Is Not Heating Properly – Here’s what could probably be causing the problem:
a). Dirty Air Filter – Most problems arise from dirty air filters. Hence, always check whether they are clogged or not. If they are, change them out with new ones.
b). Low Refrigerant – If the refrigerant charge is low, it will not allow the heat pump to bring in adequate heat from outdoors. Again you will have to depend on the technician to plug the leak source and top it up.
c). Blockage Around The Unit – Every kind of heating and cooling system, heat pumps included, need unrestricted airflow. If there are any impediments, it will affect heating. If the airflow to the heat pump is blocked due to piles of leaves or other debris, or accumulations of snow and ice, clearing them will resolve the heating problem.
3. Heat Pump Does Not Turn On – This too is a usual occurrence and can occur due to any of the following reasons:
a) No Power – Probably the electricity in your locality is out. There’s nothing you can do but wait for the power to come back. It could also be a tripped circuit breaker. If that’s the case, correcting the trip by pushing the switch back to “On” will resolve the issue. Anything other than that, better call the technician.
b) Thermostat Problem – First, check the thermostat batteries and the program you have set. If all is in order, possibly the thermostat needs recalibration. Call the HVAC technician, and he shall do the needful.
c) Starter Capacitor Is Broken – Components suffer wear and tear with long hours of continuous use. If there is a clicking sound coming from the heat pump when switched on, and nothing happens beyond that, the starter capacitor is highly likely to be broken. The HVAC technician can switch it out for you.
4. Heat Pump Is Running Without Any Breaks – Ideally, every heating and cooling system takes a break when the desired temperature is achieved. If your heat pump is running endlessly, these could be the reasons:
a) Extreme Weather – As we mentioned initially, a heat pump is meant for places with moderate temperatures. If there is an extreme weather front, your heat pump may work continuously to maintain the indoor temperature.
b) Thermostat’s Calibration Is Off – If the thermostat’s calibration is off, it will not correctly judge when to signal the heat pump to stop. In the absence of the stop signal, the heat pump will work continuously. Call a professional to recalibrate the thermostat.
c) Compressor Contractor Is Broken – The work of the compressor contractor is to control the power to the heat pump. If it suffers any damage or malfunction, it will not know when to stop the power supply, and the heat pump will run endlessly. The only option is to replace the defective or broken contractor with a new one.
