When to call right away
What counts
as an emergency.
If any of these happen, call us any time. Safety first: if you smell gas (rotten eggs) or your carbon monoxide alarm goes off, leave the house now and call 911 or your gas company from outside.
No heat in freezing weather
Cold homes can be dangerous, and frozen pipes can follow.
Water leaking from the system
Turn the system off to protect your floors and ceiling.
Burning or electrical smell
Turn the system off at the thermostat and call us.
Breaker trips when it starts
Don’t keep resetting it. That’s a sign of an electrical problem.
System won’t shut off
A system that runs nonstop can freeze up or overheat.

Emergency service FAQ
Do you really answer 24/7?
Yes. A real person answers 817-795-0858 day or night, every day.
How fast can you get here?
It depends on the time and how busy we are. We’ll give you the earliest available time when you call, and same-day service is often available.
What should I do while I wait?
No cooling: close the blinds, keep doors closed and run fans, and turn the system off if it’s iced up or leaking. No heat: check the thermostat and breaker, close off unused rooms, and use space heaters safely, with 3 feet of clear space and plugged straight into the wall.
What if I smell gas?
Leave the house right away and call 911 or your gas company from outside. Don’t use light switches or phones inside.
