AC Troubleshooting Checklist
Outside the Home
- Is the A/C cover removed from the unit?
- Is the disconnect box turned on? It is a grey box with a plug/handle that is on the outside wall beside the unit.
- Is there ice on the outside of the unit or pipes? If so, the unit must be thawed 24-48 hours before booking. Readings will not be right if the unit is frozen and we will not be able to properly diagnose.
- Are the fins on the unit dirty or clogged? If so, disconnect the high voltage power for the A/C in the panel, then rinse with the water hose (do not use a pressure washer).
- It must be over 18C outside so we can diagnose your unit properly.
Inside the Home
- Make sure the thermostat is turned to cool.
- Check to see if you need new batteries in the thermostat. If batteries are older than 1 year old, they should be replaced.
- Is the furnace switch turned on? (It looks like a light switch, and is located in the basement usually higher on the wall near the basement stairs or door to the furnace room).
- Check the furnace filter- if your filter is more than one month old you should replace and/or clean it.
- Is the furnace fan running with the HRV switched off and the thermostat fan set to ‘auto’? This tells us if the thermostat is calling for A/C if the fan is running.
- Is the breaker in the breaker panel turned on? Normally it is a double breaker marked A/C.
- Is there water leaking from the furnace? If yes, it is probably frozen- turn off for 24 hours.
- Is there ice on the pipes or ductwork in the basement? If so, the unit must be thawed 24-48 hours before booking a service call. Readings will not be right if the unit is frozen and we will not be able to properly diagnose.
- Is your equipment an Enercare rental? You will have to contact the rental company for service.
Why Is My AC Blowing Hot Air?
There are a number of reasons your AC may be blowing hot air. Try troubleshooting them on your own before calling us for professional assistance.
- Thermostat Issue – Ensure the thermostat is set to the ‘ON’ mode, not ‘AUTO,’ to prevent constant airflow regardless of cooling needs.
- Tripped Breakers – Check both inside and outside unit breaker switches; a tripped outside unit breaker may cause warm air circulation.
- Dirty AC Filter – Regularly clean or replace air filters to prevent airflow restriction caused by dirt and debris accumulation.
- Low Refrigerant Level – Low refrigerant levels, often due to leaks, can cause the AC to blow warm air. Contact professionals for prompt repair.
- Other Issues – If none of the above apply, the AC may need maintenance or cleaning. Professional inspection can identify and resolve underlying problems.
