If you schedule regular heat pump maintenance, you should expect it to be in excellent working condition for a long time. However, this doesn't mean that you won't experience issues from time to time. A common problem with heat pumps, especially in winter, is that they can start to blow cold air even when you switch to heat mode. If this happens, it's crucial to seek the services of a professional heating technician. Different factors can cause your heat pump to experience this problem, and this guide has highlighted a few problems you should be aware of.

Your Heat Pump Likely Has Low Refrigerant Levels

The refrigerant in your heat pump can be gaseous or liquid, and it's responsible for absorbing heat from the atmosphere then distributing it around your home. When the heat pump has low freon levels, the evaporator coil's ability to absorb heat will be compromised. So, your heat pump will begin blowing cold air. A low refrigerant level indicates a possible leak. Remember that continuous exposure to the refrigerant can lead to numerous health complications. If you believe that your refrigerant is leaking, ensure that you call a heating repair technician to check your system and advise on the need for repairs.

Your Air Filter Is Likely Clogged or Dirty

When you fail to regularly change your air filter, it hinders the adequate flow of air through your heat pump. The heavy buildup of grime and dirt on different parts of your heat pump such as the condenser and evaporator coils can hinder their performance. This prevents your heater from distributing warm air. It's advisable to replace your filter after every few months. Seek the help of a professional heating repair technician for consultation and any replacements.

Your Heat Pump Reverse Valve Is Faulty

Heat pumps feature a reverse valve that reverses the flow of refrigerant. This is designed to ensure that the heat pump easily switches between the 'heat' and 'cool' modes. If there are issues with this valve, your heater won't effectively change between the two modes. If it's stuck in cooling mode, it will continuously blow cold instead of warm air. The only way to address this problem is to call a heating system repair technician to inspect your heat pump and perform repairs.

A heat pump helps keep your indoor temperatures at optimal levels during the cold season. So, when it stops blowing warm air, ensure that you address the issue immediately. The few factors listed in this guide should help you understand the possible reasons for such a malfunction. Call a contractor if you need a heating repair in your home.
