If your heat pump has undergone many repairs and is constantly in need of spare parts then it is time to think about heat pump replacement. A faulty heat pump will cause untold misery in your house. You will likely experience very warm summers and very cool winters. You need to consider whether to replace the entire heat pump or make parts replacement.
Age of Heat Pump and Boiler
If your heat pump has been in service for at least 10 years, it may be necessary to retire it and replace it with a new heat pump. The natural process of wear and tear causes the heat pump to operate at reduced efficiency. Reduced operational efficiency leads to increased operational expenses in terms of the purchase of spare parts and longer down time. You also need to check the age of the boiler. If the boiler has been in operation for at least 15 years you need to replace it. Holding on to it will lead to excessive operational costs in terms of frequent repairs and replacement costs.
Disparities in Heating and Cooling Levels
One of the signs of a faulty heat pump is lack of uniformity in the room temperature in the house. Inefficient equipment, poor insulation and defects in the duct system are a prime cause of this problem. In such a case, the best solution will be to replace the old pump with a new heat pump.
Humid Conditions and Excessive Dust
A faulty heat pump may lead to discomfort in the house as air gets too dry in winter and too humid in summer. Leaking ducts and inefficient equipment may cause such a problem. Leaking ducts may also cause excessive dust to accumulate in the home. This occurs when the ducts suck in particles and air from the attic and other dusty places within the house and then distributes it throughout the home. The remedy in such a case will be to replace the old pump with a new one.
Noisy Heat Pump
Excessive noise generated by the pump is a sign that not all is well. One of the possible causes of this phenomenon is an undersized duct system. A defective indoor coil within the cooling system may also cause the pump to produce excessive noise. It is prudent to replace it as the cost of repairs and frequent breakdown may easily surpass the cost of replacement.
Increased Maintenance Costs
Go through a monthly record of the bills and expenses incurred on the heat pump. Observe the trend on a month-by-month basis. If the trend indicates that the expenses have been increasing steadily it means that the heat pump is no longer operating under optimal conditions and it is necessary to replace it with a new one. Continued usage will result in ever-increasing bills without the benefit of reasonable service.
