Common Heat Pump Performance Problems

The heat pump in your home needs to work year round to provide heat and air conditioning. This is why you want to make sure it’s performing as efficiently as possible to save on energy costs and prevent break downs. You should schedule an annual maintenance check-up and inspection with a certified HVAC technician to test the efficiency levels. However, there are a few common causes of performance issues to be aware of so that you can be sure your heat pump performs at optimal levels. Call Air Mechanical if you have questions about heat pump performance issues, or to make an appointment for an annual inspection and professional cleaning.

Airflow Issues

There should always be a certain amount of airflow (measured in cubic feet per minute) in your heat pump to maintain proper efficiency levels. If the airflow is less than 350 cfm per ton, it could increase your energy costs. You should make sure your Maple Grove HVAC contractor checks the airflow whenever your heat pump is inspected. Always keep the coils clean. Sometimes the ducts are not the right size, or the fan speed needs to be increased, but often cleaning the coils will help airflow, which is why it is important to clean and maintain the components of your heat pump. A certified technician will know what methods are best, so if you suspect an airflow problem with your heat pump, call a professional heating technician.

Air Leaks in the Duct System

Inefficient or poorly-designed duct systems may not distribute air properly throughout your home because of potential air leaks. There should always be a balance between the intake and return air in a forced air system, which helps maintain a neutral pressure within the house and increase efficiency. Some contractors argue over how tightly a house should be sealed for this reason, but if your heat pump is losing heat through leaks in the air ducts, this will greatly affect its efficiency.

Improper Refrigerant

Refrigerant leaks are another common cause of low performance levels in heat pumps. Most heat pumps already have refrigerant when they leave the factory and shouldn’t have any issues. Heat pumps that are charged with refrigerant when they are installed can sometimes have the wrong amount of refrigerant. Either too much or too little refrigerant will lower the heat pump’s efficiency and performance levels. Always check the recommended refrigerant amount or ask an HVAC technician before you add refrigerant yourself. If the heat pump in your Maple Grove home isn't working properly, it is also affecting your heating bills. Call Air Mechanical today to set up an appointment.
