Simple DIY things to check before you call

Check the batteries in your thermostat... make sure it's in the proper on/off/auto position.

Hearing a vibration sound?  Improper fitting filters can cause a vibrating noise.

Everything abruptly stops working & someone has been in your attic, check a light switch that may have been inadvertently shut off.

Check your breaker.  Common power surges will cause your breaker to be thrown.  Call if the problem persists.

Check your filters.  Dirty filters will really restrict proper air flow and can actually cause the system to ice up & fail.


A furnace door that has vibrated loose will abruptly disable the system...make sure the door is secure...a simple DIY check.
