Or call directly: (720) 527-0668
When you call (720) 527-0668 for an emergency, a real person answers — not a voicemail, not an answering service. We'll ask a few quick questions to assess the situation and dispatch a technician with the right parts on the truck.
Our emergency rate is the same as our regular rate. No overtime charges, no after-hours surcharges, no weekend premiums. We believe emergency pricing shouldn't punish homeowners for having equipment fail at a bad time.
If you smell gas or your carbon monoxide detector is going off, leave the house first and call 911. Then call us. Gas leaks and CO exposure are safety emergencies that require immediate evacuation before any HVAC work can be done.
For no-heat emergencies during Colorado winters, close interior doors to keep warm rooms warm, let faucets drip to prevent frozen pipes, and use space heaters safely while you wait. We'll get there as fast as we can.
