A great investment for the comfort of your home is an air conditioner. Naturally, what you would want is longevity and good performance. Something that you may experience often is short cycling, where the unit turns on and off repeatedly—giving you higher energy consumption, wildly uneven temperature, and a malfunctioning air conditioner unit. All of these can be caused by a variety of different elements that you fail to notice in your unit.

Dirty Air Filter

Ideally, your air filter must be cleaned or replaced every 30 days. A clogged unit means a blockage that restricts your airflow. To solve this, simply turn your unit back on after letting it rest for a few minutes, and it should work just fine. As you can see, there are quick check-ups and fixes you can do yourself. 

Dirty or Frozen Evaporator Coil

The refrigerant in it won’t be able to absorb heat from the air. It will be tricky to clean this up better call your HVAC contractor to help you out.

Dirty Condenser

Your unit’s condenser is always exposed outside. It’s more prone to dust, dirt, or debris, and other parts of your unit. Check if no grass or foliage is obstructing its airflow. 

Thermostat Issues

Sometimes, the problem might be brought by your thermostat. It might have inaccurate readings if it is placed somewhere near windows, kitchens, or vents. Place it somewhere near the center of your house.

 Check the settings on your thermostat. There might be some problem with the timer. Consult your owner’s manual to see how to change it.

Look at the screen of your thermostat. If it is blank, it might need some new batteries or is broken. If it is the latter, call a professional for repair or replacement.

Grime In The Compressor

The compressor might overheat if there is a buildup of grime in it. It might malfunction or fail. This is an essential part of your air conditioner, call your contractor to help you with it. 

Low Refrigerant Level

 The refrigerant in your unit is responsible for absorbing heat from the environment. It runs through the coils and the compressor. Your air conditioner won’t work efficiently and short cycle, if it lacks refrigerant. You may ask your technician to detect if your unit has the correct amount of refrigerant in it. If not, it only needs a recharge.

A more complex problem you might have is a refrigerant leak. Sensors within your air conditioner will turn it off if it detects a leak. It will cause to have a low refrigerant level. It is better to call your HVAC contractor for help.

Short cycling is a sign of trouble in your air conditioner. Make sure to contact a professional for help if it is getting out of hand.
