Electric heat pumps are essential HVAC equipment that facilitates heat energy transfer from the source to the required destination. Electric heat pumps are designed to help transfer thermal energy against its spontaneous flow direction by absorbing the heat in a cold area and transferring it in a warm area. Like any other mechanical device, these systems begin to age and stop functioning effectively over time, a sign that they need replacement. Even the best HVAC systems eventually age. Your heat pump is placed under a great deal of strain from its years of constant operations. There will come a time when age will eventually catch up with your system. Electric heat pumps have an expected service life of about 10 to 15 years. The more they are in operation, the more they continue to age internally in irreversible ways. Your system doesn’t have to stop operating for you to tell that it has aged. Even if your system seems to be operating fine, its old age should be enough to warrant a replacement. An aging electric heat pump will constantly need repairs. The cost of these repairs may sometimes be as high as or even more than the costs of purchasing a new heat pump. An aging heat pump will create unusual noises even though they are designed to operate smoothly, with minimal friction and internal resistance. An aging electric heat pump causes a rise in energy consumption and bills. You will also experience inconsistent heat supply around the house. If certain parts of your home are always too cold or too cold, you could be experiencing an aging electric heat pump.
