Helpful Tips from Trustco
Things to try before calling for service:
- If your system has a filter, turn equipment off and check for a clog or dirty filter.
- Reset all breakers or switches for equipment; remember that some systems have 2 breakers.
- Turn thermostat off then on, wait 10 minutes and check if running.
- Clear all debris and obstructions from equipment.
- If equipment has a circuit board with status L.E.D. lights, take note of the pattern or numbers of L.E.D. blinks and consult owners manual or call Trustco Heating and Air for advice.
- Make sure there are no blocked or closed air vents through out the house.
- If equipment or copper line set are iced up and won't defrost themselves, turn off and defrost for 24 hours and then check items 1, 4 and 6. Call for service if problems persist. Note for heat pumps: Temporarily switch thermostat to emergency heat until problem is solved.
- Consult equipment owner's manual for instructions and troubleshooting tips.
