It’s the middle of a hot summer heatwave and you start to notice that your house isn’t as cool as you’d like it to be. You ask yourself, “Why is my AC not working?” Or, “Why is my air conditioner not turning on?”
Unfortunately, getting your air conditioner up and running properly again isn’t always a simple fix. An AC unit is a complex piece of technology that requires regular maintenance and expert knowledge to repair. Wondering what to do if your air conditioner stops working altogether? Read on to discover the reasons your AC may not be working and how to start the troubleshooting process.
What Can Cause an Air Conditioner to Stop Working?
There are a number of reasons why your air conditioner may not be working. Some of the most common reasons include:
- Inadequate maintenance resulting in the buildup of dust and debris on filters and air conditioning coils
- Problems with thermostat sensors, which can cause your AC to run constantly or erratically
- Leaking refrigerant
- Poor installation or repair, causing the unit to malfunction
- Electrical component failure resulting from corrosion of wires and contacts
What to Do When Your AC is Broken
Depending on the reason why your air conditioner is not working, you may be able to get it cooling again. Try these simple steps to determine if the issue is something you can fix on your own:
If Your AC Doesn’t Turn On
First of all, ensure that your air conditioning unit is plugged in. If it is plugged in, check for a tripped circuit breaker or blown fuse. Reset the breaker if necessary. Don’t forget the check your thermostat to ensure it is set to cool, and lower the temperature by a few degrees to see if the AC kicks in.
If Your Air Conditioner Isn’t Cooling Well
Should your AC unit not perform as well as it used to, check the coils and filters to ensure nothing is blocking the air flow. Clean the coils and replace or clean the filter thoroughly to remove any dust or debris.
If Your AC Unit Shuts On and Off Repeatedly
A dirty or obstructed condenser unit or dirty evaporator can cause your air conditioner to keep turning off and on. Give the unit a thorough cleaning to remove debris in order to get it running properly again.
If Your Air Conditioner is Still Broken…
It’s time to call in a professional. After basic troubleshooting and cleaning, an air conditioner that is still not working needs the attention of an expert who understand the complexities of AC technology, especially when it comes to repairing problems with the electrical and coolant systems.
