Emergency Service

24/7 Emergency Dispatch

After-hours and weekend furnace failures get our 24/7 dispatch. A real licensed technician answers the phone — not a call center, not voicemail. We prioritize emergencies by safety risk.

Emergency calls run at higher rates than scheduled service. If your furnace issue can wait until the next business day, you'll save money — and we'll be honest about that on the call.
