Troubleshooting Common Air Conditioning Problems: DIY Fixes and When to Call a Pro

Is your air conditioner blowing warm air instead of cool, or not turning on at all? These are common problems that can arise with air conditioning units, but don’t worry – in this article, we will guide you through some DIY fixes to help get your AC back up and running. However, it’s important to note that not all AC problems can be fixed with DIY solutions, and in some cases, it’s best to call in a professional. Let’s explore some common AC problems and their solutions.

Problem #1: Air conditioner is not turning on

If your air conditioner is not turning on, the first step is to check the thermostat. Make sure it is set to the “cool” setting, and that the temperature is set lower than the current room temperature. If the thermostat settings are correct, then check the circuit breaker to make sure it has not tripped. If neither of these solutions fixes the problem, it’s time to call in a professional.

Problem #2: Air conditioner is blowing warm air

If your air conditioner is blowing warm air, the first step is to check the air filter. A dirty air filter can restrict airflow, causing the AC to blow warm air. Replace the filter if it’s dirty and see if that fixes the problem. If the air filter is not the issue, then the problem could be a refrigerant leak. This is not a DIY fix and requires a professional to diagnose and repair.

Problem #3: Air conditioner is making strange noises

If your air conditioner is making strange noises such as rattling or banging, it’s important to turn off the AC immediately. These noises could be a sign of a serious problem, such as a loose part or a failing motor. Continuing to run the AC could cause further damage. Call in a professional to diagnose and repair the issue.

Problem #4: Air conditioner is leaking water

If you notice water leaking from your air conditioner, the first step is to check the condensate drain. A clogged drain can cause water to back up and leak out of the unit. Clear any clogs and see if that fixes the issue. If the drain is not the problem, then the issue could be a refrigerant leak or a damaged condensate pan. Call in a professional to diagnose and repair the issue.

Problem #5: Air conditioner is freezing up

If your air conditioner is freezing up, the first step is to turn off the AC and let it thaw out. This can take several hours or even overnight. Once the unit is thawed, check the air filter and replace it if it’s dirty. If the air filter is not the problem, then the issue could be a refrigerant leak or a dirty evaporator coil. Call in a professional to diagnose and repair the issue.

When to Call a Pro

As previously mentioned, not all AC problems can be fixed with DIY solutions. Here are some signs that it’s time to call in a professional:

  • Strange noises coming from the AC
  • Refrigerant leaks
  • Electrical issues
  • Frequent breakdowns
  • Air conditioner is over 10 years old

In these situations, it’s best to call in an experienced HVAC technician to diagnose and repair the issue. Attempting DIY fixes for these problems could cause further damage and end up costing you more money in the long run.

In conclusion, while there are some common air conditioning problems that can be fixed with DIY solutions, it’s important to know when to call in a professional. If you’re unsure about how to fix an AC issue, or if the problem persists after attempting DIY solutions, it’s best to call in an experienced technician. Regular maintenance and tune-ups can also help prevent AC
