If you’ve ever had your heat pump checked by a professional, they might have told you it’s low on pressure. But what does that mean, and why is it happening? When your heat pump loses pressure, it can cause problems with your entire heating system. Here are some of the most common reasons a heat pump loses pressure and what you can do about it.

1. A Leak in the System

An outdoor or indoor unit leak can cause your heat pump to lose pressure. If the leak is in the outdoor unit, freon will escape from the system and cause the compressor to overheat. If the leak is in the indoor unit, air will escape from the system and cause the evaporator coil to freeze. A pressure loss will reduce the heat pump’s efficiency and increase energy bills. To prevent leaks, ensure that all connections are secure and that there are no cracks or holes in the outdoor or indoor unit. If you think your system might be leaking, it’s best to call a professional to evaluate.

2. The Refrigerant Is Low

Every heat pump has a certain amount of refrigerant required for proper operation. If the refrigerant level falls below where it needs to be, it can cause problems with pressure. This is usually due to leaks, but it could also be due to an improperly sized unit or incorrect installation. If you’re unsure whether your heat pump has the right amount of refrigerant, schedule an appointment with a heating expert from Bryant’s Heating & Cooling to assess it correctly and make the necessary repairs.

3. The Compressor Is Failing

The compressor is one of the most critical parts of the system, and if it’s not working properly, it can cause all sorts of problems, including reduced pressure for your heat pump. As a result, the heat pump will be unable to effectively transfer heat, leading to reduced efficiency and higher utility bills. If you think your compressor is failing, contact an expert for diagnosis and repair.
