Why Is My Air Conditioner Not Blowing Cold Air?
There's nothing worse than finding out your air conditioner is not working on a hot summer day. Anyone in Minnesota knows how warm the temperatures can get, and you depend on a functioning A/C unit to maintain comfort.
In our 20 years in the business, Tiger Plumbing, Heating, & Air has seen it all, so we've created this comprehensive guide with the most common issues that cause it to malfunction.
Let's dive in!
Low Refrigerant Levels Could Be the Issue
Refrigerant is crucial for absorbing and dissipating heat, making it essential for cooling. If your system is low on refrigerant, it could indicate a leak.
A few things to check for are:
- Listen for Hissing Sounds: A hissing noise could indicate a leak.
- Inspect for Ice: Ice buildup on the refrigerant lines or evaporator coil is a sign.
- Cooling Performance: If your A/C isn't cooling properly, you may need to refill the refrigerant.
If the issue isn't apparent, we never recommend DIY-ing the job. Contact an HVAC technician and get expert support.
The Condenser Might Be Blocked
The condenser, located outside, dissipates heat from the refrigerant. If it's blocked with debris, like leaves or grass, it can't function correctly, and your A/C won't cool the air efficiently.
To check and clear the condenser, follow these steps:
- Turn Off the Power: Always shut off power before maintenance.
- Inspect the Area: Clear any visible debris around the unit.
- Clean the Fins: Use a gentle stream to remove dirt from the fins.
- Trim Vegetation: Ensure at least two feet of clearance around the unit.
Dirty Air Filters Are Problematic
A dirty air filter restricts airflow, forcing your A/C to work harder and reducing efficiency. This leads to poor cooling performance and increased energy bills.
- Locate the Filter: Usually in the return air duct or blower compartment.
- Inspect the Filter: If it looks dirty or clogged, it's time to replace it.
- Replace the Filter: Follow manufacturer instructions for replacement.
Electrical Issues Will Affect the Unit
Electrical problems can prevent your air conditioner from blowing cold air. Issues with wiring, fuses, or capacitors might be the culprit and can be harder to diagnose.
Signs you have an electrical problem on your hands:
- A/C Won't Turn On: This might indicate a tripped breaker or blown fuse.
- Inconsistent Operation: Frequent cycling on and off can signify electrical problems.
Electrical issues are best left to professionals due to the risk involved, so always contact an HVAC technician to diagnose and fix these problems.
Your Thermostat Might Be the Cause
Sometimes, the issue lies not with the AC unit but with the thermostat. It won't signal the A/C to start cooling if it's not functioning correctly.
A few troubleshooting tips are:
- Check Settings: Make sure it's set to "cool" and the temperature setting is lower than the room temperature.
- Inspect for Dust: Clean any dust that could interfere with its operation.
- Replace Batteries: If applicable, replace thermostat batteries.
If you get through all these and the problems persist, you might need a new thermostat.
