An AC Repair Specialist Outlines What Causes a Heat Pump To Blow Cold Air In Heating Mode? | Bullhead City, AZ

A heat pump is essential for your home’s comfort, especially during the cold months. Reliable, energy-efficient, and easy to install, heat pumps are a popular choice for most homeowners who want a two-in-one HVAC system. Although a heat pump can be used for both heating and cooling purposes, it can be worrying when your heat pump blows cold air in heating mode. When this happens, it means something is wrong with your heat pump, and it needs to be inspected by an AC repair professional in Bullhead City, AZ. The last thing you want is a malfunctioning heat pump when it’s cold. Some of the reasons your unit is giving out cold air in heating mode include the following:

The Filter is Dirty

A filter is an essential heat pump component. It helps remove dirt, dust, and other debris from the air before circulating throughout your home. It becomes clogged when you don’t hire an AC repair technician to regularly clean or change the filter. If the filter becomes clogged, it can restrict airflow to the unit, causing the heat pump to work harder to circulate warm air. This can lead to reduced efficiency, and in some cases, the heat pump may stop functioning altogether and blow cold air instead. To prevent this issue, have an AC repair expert check and change the air filter after every six months to ensure proper airflow and optimal performance of the heat pump.

Setting the Thermostat in the Wrong Mode

Heat pumps have different modes of operation. The modes include “cool”, “heat”, “auto”, and “emergency heat” modes. The HVAC system will blow cold air if the thermostat is set to “cool” mode instead of “heat” mode. Also, if the thermostat is set to “auto” mode, it may switch to blowing cold air if it detects that the room is already at the desired temperature.

When set to “emergency heat” mode, it will bypass the heat pump and use an auxiliary electric heating element instead, which may cause the air coming out of the vents to be cooler than normal. Therefore, it is important to check that the thermostat is set to the correct mode and that the temperature setting is also appropriate.

To avoid issues with your thermostat, contact an AC repair company in Bullhead City, AZ, and they will help you install a programmable thermostat. Unlike traditional thermostats, a programmable thermostat is energy-saving and ensures your home is always comfortable.

Low Refrigerant Levels

For your heat pump to operate well, it must have the correct refrigerant levels. Like most HVAC systems, a heat pump uses refrigerant to absorb heat from the outside and move it indoors. If the refrigerant levels are inadequate in the heat pump, the heat pump will not be able to transfer enough heat to warm the air, resulting in cold air blowing out of the vents. Leaks in the system, improper installation or maintenance, or other issues can cause low refrigerant levels. Whatever the cause is, have an AC repair professional do an inspection.

It’s important to note that a non-certified AC repair technician should not fix any issues with refrigerant leaks. They should be licensed and certified because refrigerant leaks can be dangerous to your health and harm the environment. Once you hire a licensed expert, they will check the refrigerant level, repair any leaks, and recharge the system with the appropriate amount of refrigerant.

A Bad Reversing Valve

The reversing valve is a component in the heat pump system that changes the direction of refrigerant flow, switching the system from heating to cooling mode or vice versa. If the valve is malfunctioning, it can prevent the heat pump from properly reversing the refrigerant flow, causing it to blow cold air instead of warm air.

A malfunctioning reversing valve can be caused by various factors, such as wear and tear, corrosion, lack of lubrication, or electrical issues. Contact a licensed AC repair expert if you suspect a bad reversing valve is causing the problem. They will diagnose your heat pump and repair it to restore its proper operation.

Bad Compressor Valves

The compressor valves regulate refrigerant flow in and out of the compressor. If the valves have an issue, they can prevent the proper flow of refrigerant, causing your unit to work incorrectly. Other signs of bad compressor valves include loud noises coming from the compressor, tripped circuit breakers, and high energy bills. Because a compressor is a complex and costly component, it’s good to contact an AC repair company to diagnose the issue and give a long-lasting solution. Avoid fixing it yourself because you can damage it.

The Outdoor Unit is Iced Over

When your heat pump works in heating mode, the outdoor unit may collect frost or ice on the coils. This can happen due to several reasons, such as low refrigerant levels, dirty air filters, or a malfunctioning defrost control. The ice buildup can restrict the airflow to the outdoor unit, preventing the HVAC system from absorbing heat from the air outside properly. As a result, the heat pump may not be able to transfer enough heat to warm the air, causing cold air to blow out of the vents.

To solve this problem, your outdoor unit will need to be defrosted, and the underlying issue causing the ice buildup needs to be addressed. Hire an AC repair professional in Bullhead City, AZ to fix this issue properly.
