First Things First
No matter the source of the issue, you need to first cut off electricity to the unit so the problem doesn’t get worse. To turn off the main power supply, flip the air conditioning switch on your main electric panel to “off”.
Once your air conditioner is off, you can attempt to locate the source of the issue. Depending on the specific problem you’re facing with your air conditioner, there are a few things that could be wrong.
Common Complications and Their Culprits
Issues with air conditioning systems can come in many forms. Here are some of the most common problems homeowners face with their air conditioning systems, and a few troubleshooting tasks to try.
How to fix your air conditioner when it’s not cooling
AC not keeping you cool? Check out these different sources to see if you can get it sorted yourself:
Check on your thermostat; it might be set incorrectly. Make sure it’s set to cool, and to the temperature that you prefer. If resetting the temperature doesn’t fix things, you may have a faulty thermostat.
Check your air filter; it might be dirty. Not to worry! Air filters accumulate dirt over time, through no fault of your own. All you need to do to fix your system is clean your AC filter.
Check on your outdoor condenser unit to see if there’s buildup covering your unit. You can clear it off with a brush or a vacuum and see if that does the trick.
Look for leaks. If your AC unit is leaking water, it’s not a good sign. Contact an HVAC technician immediately to have your unit repaired.
If one of these sources does not uncover the source of your issue, there may be another reason why your AC is not blowing cold air. Contact a technician for some extra support.
How to fix a frozen AC unit
If you’re noticing signs that your AC unit is frozen, such as frost accumulation or ineffective cooling, first check to see if your air filter’s clean. If it’s dirty, no worries! This is a normal part of AC life. To fix your system, just clean your AC filter.
If the air filter was not the culprit here, then something more serious might be going on. Contact your local HVAC specialist to have your unit inspected for:
Frozen evaporator coils
How to fix your air conditioner if it’s leaking water
If your AC unit is leaking, there are a couple of things you can do to try to fix it yourself:
Check your air filter to make sure it’s clean. If it’s dirty, clean your AC filter and see if that gets your system back on track.
Check on the condensate pan. Is it full? Then you’ll need to empty it. However, this is a suspicious issue — you’ll need to call in the pros to find out what went wrong.
If these two troubleshooting checks don’t turn up the source of the issue, there might be something more serious going on. You’ll need an expert to determine if another problem is at play, like:
Drain line is blocked
AC unit was installed incorrectly
The refrigerant level is low due to a leak
All of these might be reasons why your air conditioner is leaking. A pro can help you uncover which one is at work.
