Why Is Your Mitsubishi Air Conditioner Not Working?

Here’s the thing about an air conditioner (and this is no big secret): they can break down when you least expect them to. A Mitsubishi aircon is no exception. While your air conditioner can be fixed through a quick AC repair in San Luis Obispo, waiting for it to be fixed is no party in the summer heat.

Not to mention, you probably want to avoid any severe problems from popping up that may cause your AC to malfunction. That’s why it is important to understand why your aircon is not working the way it should.

Five Reasons Why Your Mitsubishi AC is Not Working

1. An Unsuitable Unit

One of the leading reasons for AC malfunction is that they are not installed correctly in the first place. Your installer needs to consider various factors like the number of windows, room size, etc., to determine how much cooling your home needs. For instance, if your AC ducts are too small, your unit will have to work twice as hard to maintain the desired temperature.

2. Unit and Plug Overload

Leaving your AC running for the whole day can be tempting, especially in the summer. However, this may overload your unit, reducing its efficiency and lifespan. Most folks also plug in their AC unit with other electrical appliances, crowding the power source. So, if your AC has stopped cooling and is connected to an overloaded plug, try shifting it to an isolated plug point.

3. Clogged Air Filters

Homeowners who fail to clean their AC’s air filters regularly risk overworking their unit to try and push out cool air through clogged filters. In extreme cases, the AC can become incapacitated and has to be replaced. It happens because the cool air circulates back into the evaporator coils, freezing the coolant in them. So, cleaning or changing your AC filters every month is a great way to keep your unit running properly.

4. Malfunctioning Thermistor or Thermostat

Your AC’s thermistor is responsible for relaying a signal that helps modify your unit’s temperature. So, one of the reasons your AC is not working could be a broken thermistor. To get this repaired, you may need to rely on professional services like AC tune-up in San Luis Obispo. You may also want to check your thermostat to see if it is calibrated and is sending the correct instructions to your indoor unit.

5. Low Coolant Levels

Cool liquid refrigerant in the evaporator coils ensures the air your AC sends out is cold. Hence, the amount of refrigerant in the unit must match the manufacturer’s specifications at all times. There are two reasons your refrigerant levels can be low:

  • Not enough coolant was added during installation.
  • Your system has developed a leak.

Unfortunately, simply adding the refrigerant will not fix the issue if a leak is the cause. You may want to contact a trained technician to fix the leak and recharge your system with the correct coolant level.

Other mechanical issues

Your Mitsubishi AC may stop working due to issues with various components like the:

  • Fan
  • Evaporator coil
  • Compressor
  • Condenser coil
  • Expansion device
