AC Unit Not Blowing Cold Air

If you’re not sure what’s wrong with your system, review the top six reasons why your unit may not blow cool air.

1.) Difficulties With Your Thermostat

If warm air blows through your vents, your thermostat may be the issue. Try troubleshooting your unit and resetting the thermostat to your desired temperature. If your air conditioner (AC) is not blowing cold air or doesn’t blow air at all, check the batteries and ensure all wires are connected. If the problem remains, contact an HVAC professional for a proper diagnosis.

2.) Clogged Drainage

If your unit isn’t serviced periodically, the moisture it removes from the air can cause a buildup of mold. To prevent any clogs from occurring in your drain hoses, contact a certified technician every six to eight months, depending on how often you use your air conditioning unit.

3.) Dirty Compressor

Over time, contaminants can impact the operation of your compressor. Typically, this is maintenance your technician will perform with a routine AC tune-up or repair. However, if you’re overdue for service and your AC unit is not blowing cold air, contact a professional to remove the build-up right away.

4.) Ice on Your Coils

If your air conditioner has a coolant leak or contaminated coils, any excess moisture could cause your coils to develop a layer of ice. If your coils are blocked by ice, they’ll be unable to absorb warm air or produce cool air. If your air conditioner (AC) unit is not blowing cold air, try running the fan in your system until the ice melts to restore the function of your cooling system. If this doesn’t work, we recommend contacting a technician on our team to professionally assess the issue.

5.) Electrical Problems

AC units are powerful electrical appliances. If your unit doesn’t blow cold air, there could be a problem with the fuse box. Check your electrical box for blown fuses or tripped switches.

6.) Decrease of Refrigerant

With low coolant levels in your air conditioner, your system will be ineffective and stop blowing cold air. Please note that coolant is hazardous and shouldn’t be added to your unit without a professional. Instead, contact an HVAC technician.

Signs That It’s Time to Perform An Air Conditioner (AC) Repair

Your AC Creates High Humidity

If your cooling system is on, but you’re sweating from the humidity in the air, contact Horizon Services for air conditioning repair. A properly functional unit will remove warm air and maintain humidity levels between 30 to 50%.

Water Leaks From Your AC

Although not a cause for concern, leakage from your unit requires maintenance. Moisture could come from a damaged pipe or blocked drain. Either way, you’ll want to address this problem while it’s still minor.

Your Cooling System Circulates Warm Air

While not always the case, if your cooling system is distributing hot air, your compressor may need to be replaced. Before you panic, contact an HVAC technician to service your cooling system immediately. Most problems require a minor fix, but if ignored, these issues can become costly repairs.

Your Unit Makes Unusual Noises

Other than clicking on and off, your cooling system should be relatively quiet. Hearing whistling, grinding, or humming sounds are definite reasons to be concerned and should be addressed immediately. Sometimes, a component of your AC unit is loose; other times, it’s a wiring issue, and the noises indicate that something is wrong and may worsen.
