Air Conditioner Troubleshooting Guide

Residents of the residential building you operate will be cranking up their air conditioning systems before you know it. You’ll want to start the warmer weather months in a comfortable zone, which means as complaint-free as possible for you and the residents. Preventative air conditioning troubleshooting and proper residential air conditioning maintenance are important.

The usual suspects of air conditioning troubleshooting

When the temperature rises and the sun shines, the last thing you want is the air conditioning to go out. Performing regular residential air conditioning maintenance will help you prevent some of the most common problems.

  • The air conditioner doesn’t work

When you start your air conditioning troubleshooting analysis, one of your biggest concerns may be that you’ll turn on the machine and hear and feel nothing. A blown fuse or a tripped circuit breaker may be the source of the power outage, requiring you to reset the circuit breaker or repair the blown fuse. It may also be the product of faulty wiring or a malfunctioning thermostat. If the problem persists then you should move forward with air conditioning services in Mesquite, TX

  • Glitches in the thermostat

It’s possible that if your thermostat is broken or wrongly calibrated, it won’t tell the air conditioner to switch on. If your thermostat is set to the lowest temperature and the device still won’t turn on, it’s time to call your HVAC repair technician, who will most likely need to recalibrate or replace the thermostat. 

Calibration issues are more common with older dial-type thermostats, but newer programmable thermostats can be difficult to program at times. When troubleshooting your air conditioning system, check your thermostat manual to make sure you’ve configured it correctly.

  • Air conditioner problems are not cool – a low refrigerant level means a low-efficiency level

As air conditioning troubleshooting reveals a device that isn’t working properly, it may be due to a lack of refrigerant. If the refrigerant level is low, it was likely undercharged during installation or a leak. 

A low refrigerant level may be the cause of your building’s inability to cool properly or the air becoming sticky. Heat and humidity cannot be effectively extracted from the air without the proper refrigerant level. Like the engine oil in your car, the refrigerant is the lifeblood of your air conditioning system.

More troubleshooting tips for air conditioners to prevent problems

  • Brush and debris should be removed from the exterior of the device and the surrounding area.
  • Filthy filters should be replaced.
  • Check for tears in the ducts and get them fixed.
  • Install a programmable thermostat to save energy and improve accuracy, but make sure you know how to use it properly.

As you can see, several issues can be avoided by using an air conditioning troubleshooting tool. Suppose you only remember one thing from an air conditioning troubleshooting article. In that case, it should be that proper maintenance is the best way to avoid issues and headaches for you and your neighbors.
