There are more subtle issues such as low refrigerant in the system, water leaking into your heat pump system, and a blocked outdoor HVAC unit
My house is fitted with a heat pump system that keeps my home’s indoor temperature at the desired levels. While the HVAC system serves me well, it occasionally breaks down, leaving me totally frustrated about what to do. When this happens, I often wonder where to begin. The HVAC system always seems complex for me actually to figure out where the problem might be. Maybe it is because a heat pump structure functions differently from the conventional air-cooled air conditioner. Fortunately, you can apply a few tricks to know where the problem in your heat pump is and fix it. Often, heat pumps freeze in winter. This mostly affects your heat pump’s outer components, which get covered by a layer of frost. While this is not unusual, things can easily get out of hand when the top part of your heat pump is completely covered by ice, or the coils become enclosed in ice, or a thick layer of snow covers the whole HVAC equipment. Apart from this, you can also tell that your heat pump has a malfunction when it does not defrost during cold winter or the outdoor fan is not working. There are more subtle issues such as low refrigerant in the system, water leaking into your heat pump system, and a blocked outdoor HVAC unit. All these issues will affect your home’s heating and cooling and your heating and air conditioning system’s overall efficiency. You might even begin to doubt if you bought a high-quality HVAC system or if your HVAC technician didn’t do their job well. But you shouldn’t because it is perfectly normal for an HVAC unit to fail occasionally, and a qualified HVAC repairman can help you restore the heat pump system to its normal functioning.
