How to Troubleshoot an AC Not Blowing Cold Air? Living in the San Diego area can be a warm or a cool experience, depending on the time of year. In the summertime months, when the weather starts to heat up, your air conditioning unit is an indispensable part of your home. Without it, you’d feel too hot indoors and be forced to stay outside. But what happens if your AC stops performing like it should and begins to blow warm air out instead of cold? This could mean that something needs to be repaired or replaced. But before you call your local repairman, here are some tips on troubleshooting your AC not blowing cold air.
The first step in troubleshooting an AC not blowing cold air is to check the thermostat in your home. It’s possible that the thermostat is set to the wrong temperature setting and is blowing out warm air. If that’s the case, the AC unit is working properly, and the problem is simply with the thermostat. Adjust the thermostat to get the AC blowing cold air again.
If the thermostat seems to be set correctly and the AC is still not blowing cold air, it may be a problem with the AC unit itself. The first possible cause to check for is a clogged air filter. The air filter traps and prevents any dirt and dust from entering the AC unit and affecting its performance. If the air filter is clogged, it won’t be able to circulate the air properly, and the AC will blow warm air instead of cold. To check for a clogged air filter, open up the air filter compartment and inspect the air filter for any blockages. If the air filter is clogged, replace the filter with a new one, and the AC should return to normal.
Another possible cause of an AC not blowing cold air could be a defective compressor. The compressor is part of the AC unit that pumps cold refrigerant into your home to cool it down. If the compressor is defective, it won’t be able to pump the refrigerant, and the AC won’t be able to cool down the air. You can easily check to see if the compressor is working by listening to the AC unit. The compressor should make a humming noise when it’s running. If you don’t hear any noise coming from the compressor, then it’s likely to be defective and needs to be replaced.
The last possible cause for an AC not blowing cold air is a faulty evaporator coil. The evaporator coil is part of the AC unit that absorbs the heat from the air and cools it down. If the evaporator coil is dirty or has developed a leak, then it won’t be able to absorb the heat correctly, and the AC will blow out warm air instead of cold. The easiest way to check for a leaking or dirty evaporator coil is to inspect it. If you see any dirt or leaks, then the coil needs to be replaced.
These are just a few possible causes for an AC not blowing cold air. If you’ve checked all the above possible causes and your AC is still not blowing cold air, then it’s best to call a qualified repair technician to inspect your unit and diagnose the issue. Your technician will be able to determine the exact cause of the problem and recommend a solution.
If all else fails and you’re still dealing with a unit that’s not blowing cold air, it may be time for a new installation. If your current system is more than ten years old, then it may be time for an upgrade. A newer, more efficient model will save you money on electricity bills and provide a more comfortable living environment.
No matter what is causing your AC to not blow cold air, there are plenty of options to consider to get the most out of your unit. Whether it’s a simple thermostat adjustment, a new air filter, a malfunctioning compressor, or a faulty evaporator coil, there are steps you can take to troubleshoot and remedy the problem.
