Troubleshooting Guides

Before you call for service, check the following:

I have no cooling

My utility bill is higher than expected

• POSSIBLE CAUSE: If you have your thermostat set to a temperature drastically warmer or cooler than the outside temperature, your system has to work harder to maintain the temperature. This can result in a higher than usual utility bill. RECOMMENDED ACTION: Try adjusting your thermostat to a more moderate temperature.

• POSSIBLE CAUSE: Your utilities company might have raised their rates. RECOMMENDED ACTION: Contact your utility company and compare the rates on your current bill with those from previous months.

I have no airflow

• POSSIBLE CAUSE: The filters for your system may need to be changed. RECOMMENDED ACTION: Consult the owner’s guide for your system to find out how to replace the filters and what type of filters you will need.
• POSSIBLE CAUSE: A dirty coil may be stopping up your system. RECOMMENDED ACTION: If it’s a problem with the coil, you’ll need the assistance of your local Trane Comfort Specialist™. Call today to schedule a visit.

My system is constantly running

• POSSIBLE CAUSE: The thermostat temperature might be set too low (in summer months) or too high (in winter months). RECOMMENDED ACTION: Try adjusting your thermostat. If this does not solve the problem, contact your local Trane Comfort Specialist™.

The drain pan is overflowing

• POSSIBLE CAUSE: The drain pan below your interior AC unit might not be moving condensation to the nearby drainage pipe. RECOMMENDED ACTION: Your electric pump, which moves the water to the nearby drainage pipe, might have come unplugged. Check to be sure. Also check to see if there are any observable kinks or blocks in the drainage line. If you have any questions, contact a Trane Comfort Specialist™.
