What Is The Midea Heat Pump?

The Midea heat pump is an energy efficient heating and cooling system. It transfers heat from the outside air into your home during winter, and reverses the process during summer by removing heat from inside your home and releasing it outside. This is an innovative way to keep you warm an fussy during the cold winter months, and keep you cool and relaxed in the hot summer months.

Midea Heat Pump Problems

1. Low Or No Heating

If your Midea heat pump is experiencing a problem with low or no heating then it may be due to;

  • Low refrigerant levels
  • Faulty thermostat settings
  • Blower fan malfunctions
  • Defrost board malfunction

Troubleshooting The Low Or No Heating Problem

  • If the refrigerant levels are low then the heat pump won’t operate efficiently so you need to have an HVAC (Heating, Ventilation and Air Conditioning) check refrigerant levels and recharge the system.
  • Make sure your thermostat is set to “heat” and the temperature is set higher than the indoor ambient temperature.
  • Check for any debris blocking air vents or intake grills and have an HVAC pro inspect the blower fan motor and components
  • The defrost board regulates the defrost cycle to prevent ice buildup. If not working properly, it can impact heating performance. This will likely require diagnosis and repair by a qualified HVAC technician.

2. Strange Noises

If you hear strange noises coming from your Midea heat pump then it’s usually a sign there could be a problem with;

  • Low refrigerant levels
  • Clogged air filters
  • Faulty fan

Troubleshooting The Strange Noises Problem

  • The heat pump has to run longer to produce the same amount of heating or cooling so you need to have an HVAC technician check the refrigerant levels and recharge the unit if necessary.
  • You need to replace or clean the air filters to restore normal function.
  • If the noise seems to be coming directly from the fan unit then the bearings or blades may be failing or damaged then you need to have a technician inspect and repair or replace fans as needed.

3. Leaking Water

If your Midea heat pump is leaking water then it typically indicates a problem with the heat pump’s condensate drain or pan. The condensate is the water that collects as a byproduct of the heat pump’s cooling process. It drains from the unit through a pipe to prevent overflow. There are a few common issues that can cause leaking like;

  • A clogged condensate drain pipe
  • Damaged condensate drain pan
  • Refrigerant leakage

Troubleshooting The Leaking Water Problem

  • You should clean out the drain pipe using a pipe cleaner or compressed air. You may also need to remove the pipe to fully clear any clogs.
  • If the darin pan develops cracks or holes then it will leak water, so the drain pan may need to be repaired or replaced by a technician.
  • Have a technician test the heat pump for refrigerant leaks and recharge or repair the system as needed.

4. Leaking Refrigerant

If your Midea heat pump is leaking refrigerant then it usually means you have a serious problem with;

  • The heat pump’s ductwork
  • Overflowing refrigerant

Troubleshooting The Leaking Refrigerant Problem

  • You should have your Midea heat pump checked by a professional HVAC technician for proper diagnosis and refilling of your heat pump’s refrigerant. The inner workings of HVAC appliances are very complicated and intricate, therefore it is highly advised that you do not attempt to resolve them without the proper expertise.

5. Energy Efficiency Issues

If you’ve noticed that your Midea heat pump electricity bills increasing significantly then it’s possible the heat pumps’s energy efficiency has decreased. This problem is usually due to;

  • Clogged filters
  • Low refrigerant levels
  • Leaking ductwork
  • Dirty condensing coils

Troubleshooting Energy Efficiency Issues

  • Check your Midea heat pump’s filters monthly and clean or replace them as needed because clean filters can improve the energy efficiency by up to 15% and reduce electricity costs.
  • Have an HVAC technician check your Midea heat pump’s refrigerant levels because properly recharging the refrigerant can increase energy efficiency by up to 20%.
  • Also seal any holes or tears in ductwork and consider adding insulation as such improvements here can increase your Midea heat pump’s efficiency by over 20% and significantly reduce heating and cooling costs.
  • Clean your Midea heat pump’s condensing coils regularly to maintain peak performance. Coil cleaning can improve energy efficiency by up to 15% and lower monthly bills.
  • A programmable thermostat can also increase your Midea heat pump’s efficiency by automatically adjusting the temperature for maximum comfort when you’re home and energy savings when you’re away.

How To Avoid Midea Heat Pump Problems

  • Clean the air filters once a month or more often if needed.
  • Vacuum the air vents and intake grills regularly to remove built-up dust. This allows for proper airflow and prevents overheating.
  • Clean the condenser coils at the beginning and end of each cooling/heating season. Use a vacuum with an extension hose or a coil cleaning brush to remove dirt and debris from the coils.
  • Check and tighten any loose refrigerant lines to prevent costly leaks and ensure maximum performance. Check any damage to the lines or insulation and have repairs made by a certified HVAC technician.
  • Lubricate the fan motors annually to prevent overheating and premature failure.

How Often Should I Service My Midea Heat Pump?

It is recommended that you have your Midea heat pump serviced by a licensed HVAC technician once a year, preferably before the start of the heating or cooling season.

Why Is My Electric Bill Higher In The Winter/Summer?

Midea heat pumps require electricity to operate the compressor and fans, so your energy usage and costs will increase during the heating and cooling seasons.


As a homeowner you want to make sure that your Midea heat pump is running efficiently and effectively at all times. Being vigilant and addressing any issues early, can help you avoid costly repairs down the road and optimize the heat pump system’s performance. While heat pumps are designed to require little maintenance, there are a few common problems that can arise. Now that you understand the most frequent Midea heat pump problems, you’ll know how to troubleshoot them or when it’s best to call in professional help.
