5 Common Home AC Unit Problems
It's expensive and annoying to fix a malfunctioning air conditioner, especially when it breaks down in the middle of the summer. Having your AC unit routinely maintained and tuned up by a qualified HVAC technician is the best way to avoid pain and repair costs. We've also developed a list of typical problems that homeowners can recognize or resolve on their own.
Problems with Air Conditioning & Troubleshooting Advice
1. Unable to start the air conditioner
The batteries in your thermostat should be checked first, and if they're dead, replaced. Ensure that the cooling mode is selected on your thermostat if your batteries are functioning properly or have been replaced. Check your circuit breaker if the thermostat is on, in the cooling mode, and properly set, but the air conditioner still won't turn on. If you have a tripped breaker, turn it back on after flicking it off to reset it. You should contact a professional if your air conditioner still won't turn on.
2. No Cold Air is Coming From the AC
Air filter inspection It could be preventing ventilation and causing your condenser to ice up if it is dusty. Change your filter once a month to avoid these problems.
3. The air conditioner is making odd noises
- Hissing: A refrigerant leak is typically the cause of this sound.
- When the AC turns on or off, there may be a relay issue.
- A problem with the blower or motor is typically indicated by thumps, rattling, or banging.
- Screeching-Usually brought on by the fan or compressor motor.
4. Outside AC Unit Is Water Leaking
It's nothing to worry about if your air conditioner starts to leak water on a hot or humid day. The AC unit may briefly freeze up and leak water when it melts when the outside temperature is 60 degrees or lower; this is normal. However, there are several causes that could point to an issue with your outside unit, including:
- A new air filter is required.
- incorrect installation
- obstructed drainpipe
- Low coolant
5. Evaporator Coil Is Frozen
If your air conditioner doesn't get enough airflow to function correctly, the evaporator coil may freeze. The lack of airflow in the system could be brought on by blocked vents or ducts, a filthy air filter, or a broken fan.
