Hello readers welcome to the new post. Here we will learn 10 REASONS WHY YOUR HEAT PUMP IS NOT COOLING YOUR HOME. The heat pump system is made to get different temperature ranges in the home. If it is cold outside the heat pump gets warm ait in the home. The system comes with both indoor and outdoor units. The outdoor unit gets and stores air and the indoor unit removes air from the home or distributes air in the home. The heat pump system is an important component for easy living life in the home irrespective of the external conditions. if the heat pump not cooling properly there will be different reasons that will be covered here. Let’s get started with 10 REASONS WHY YOUR HEAT PUMP IS NOT COOLING YOUR HOME.
What Is a Heat Pump and How Does It Work?
Any type of heat pump comes with the same working features. Then the burning fuel to produce heat just removes heat from one place to another. There are two main types of heat pumps.
Air Source Heat Pumps
- The air source heat pumps shift heat between the external side of the home and the air in the room. This heat pump also comes with two sub-types. Ducted and ductless heat pumps. Ductless heat pumps are less invasive. Just a small hole in the wall is needed to connect indoor and outdoor units. Normally there is one unit for each room. While ducted heat pump comes with one central unit that heats or cools the complete home with the use of ducts.
Ground Source Heat Pumps
- Ground source heat pump shifts heat between the inner home side and the ground outside. its working principle is like the air source heat pump.
- The heat pump absorbs heat from external air and shifts to internal air in heating mode. In cooling mode heat pump works like the AC unit. it gets heat from the indoor unit and releases it to the external environment through the outdoor unit.
Why Is My Heat Pump Not Blowing Cold Air?
The main causes are listed here
- The thermostat is set to heating mode and will release warm air. The easy method to solve this issue of check the setting of the thermostat temperature and then move to cool mode.
- If the thermostat is in cooling mode and it is checked that the heat pump is not blowing cold air, the jammed reversing valve can be the main reason for that problem. The heat pump is stuck in a heating mode not moving to cooling mode so stop cooling air moving in the home. Get the services of a professional to solve this issue.
- The power problems resulted in the heat pump stopping operation completely. If it occurs no warm air and no cool air will be distributed in the home. For this perform these actions: Check the breaker setting and make sure accurate setting. Ensure that both indoor and outdoor units are in the ON state, Is the reset button of the outdoor unit activated? if it occurs reactive the button by pressing. If not occur get the service of a professional
- The frozen heat pump avoids accurate heat shifting in the system. Follow these steps to solve this issue. Close teh system leakage that does the release of refrigerant. Connect the new air filter if the current is dirty. Clean the dirty coils.
- if a heat pump is not cooling the living room the source of the problem be a fault blower in the system. Cool air exists in the system, but it can’t move through the home without an accurate working blower. If this problem exists ensure the thermostat is at AUTO state. if the system is set to AUTO mode but there air is not circulating get the help of an expert.
- In winter a thin layer of ice can be gathered on outdoor units. As a result, the heat pump goes to defrost mode to remove that ice layer. But a thick layer of ice stops the transfer of heat between the external coil and outside air. So the heat pump is not able to heat of house accurately. if ice exists on the outer unit for a longer duration it can result in damage to the heat pump.
- The air handle operates in conjunction with the heat pump to distribute air in the home. If the outdoor unit is operating but we did not feel any air coming from registers it means the indoor air handler is not working.
- Short cycling occurs when the heat pump repeatedly runs off when we are on it. The main casues of short cycling are, improper sizes unit, Overheating of the system, Leakage of refrigerant, and thermostats are not accurately calibrated.
- If tha mold grows on the wall close to the heat pump it can leak. Do not ignore the heat pump leaking liquid. With the decay stagnant water in the heat pump can result the electrical damage.
- There is a smell that exists on the external unit can casues the main issue of the heat pump not working well This can be due to Mold Growth, Animal Infiltration
Main Parts of Heat Pump System
The main parts of the heat pump are listed here.
- The outdoor unit tha used for capturing and storing both warm and cool air. It comes with a condensing coil and compressor.
- The air handle distributes air accurately in the home and comes with an evaporator coil, blower motor, and electrical heater
- it has an emergency electric eater that provides the heat to the home that is not heated just with a heat pump alone. The heater comes with the same component as the air handler.
- The liquid known as refrigerant passes through the system to soak up or repel heat. If the heat pump is not blowing cold air in living areas it means there is a larger refrigerant leak.
- Some composers distribute refrigerant to evaporator coils in air handlers. This comment comes with a reversing valve, fan motor defrost controls, and other electrical components.
- it has a reversing valve that is used to airflow in and out of the home by switching that moves refrigerant. Airflow occurs when the valve is on but stops when the valve is in the off state.
- The air conditioning will not occur without a thermal expansion valve. it controls the speed of refrigerant movement through the heat pump.
The heat pump not cooling below 80 degrees
- If the refrigerant level is shallow if there is a leak, a heat pump will not cool the home. Normal heat pump maintenance is the best technique to find problems with refrigerant or any other leaks.
HEAT PUMP NOT WORKING IN COLD WEATHER
Since the heat pumps lose effectively as outdoor temperature decreases less than the freezing point and the system comes with supplemental heat sources that are electrical resistance heat components or gas or oil furnaces. ‘If the heating problem is with the outdoor unit we can be able to base it on a supplemental heat source for accurate working until you get the service of a professional.

Faqs
Why is my heat pump working but not cooling?
If there is air blowing out, but it is not cold or there is no high air pressure then check the air filter. Ensure that the air filter is clean. if a heat pump is not blowing cold air at a low volume and there is a longer time to get cool the refrigerant needs to change.
Why is my AC pumping air but not cooling?
it can be a problem with the thermostat, compressor, and evaporator coils.
Why is my AC not getting cold?
First of all, check filters and coils for dirt and debris that can be impeding airflow. When you clean the filter and coils run ac unit with the fan so that ice gathers can melt off. If ac still does not produce cold air it can be that refrigerant at a low level.
