CALL US FOR EMERGENCY FURNACE REPAIR IF...
YOU SMELL GAS OR ROTTEN EGGS
Leave the house immediately. Call your gas utility from outside (CoServ: 940-321-7800 / Atmos: 866-322-8667), then 911.
YOUR CO DETECTOR IS ALARMING
Leave the house and call 911. We can't get your system operating safely until emergency services have assessed the situation.
YOU SEE FLAMES OUTSIDE THE BURNER AREA
This is flame rollout (usually a blocked flue or cracked heat exchanger). Shut the furnace off at the switch and call us.
YOU NOTICE YELLOW FLAMES OR SOOT AROUND THE UNIT.
Yellow, orange, or flickering means incomplete combustion and elevated CO. Shut down the unit and call us.
YOU'RE EXPERIENCING HEADACHES, NAUSEA, OR FLU SYMPTOMS
These improve when you leave the house, which can indicate CO exposure. Get out and get checked.
