Safety note
If you smell gas, suspect carbon monoxide, or an alarm sounds, leave the building and contact the gas utility or emergency services from a safe location.
Start with the symptom
What usually brings the call into dispatch.
The same symptom can have several causes. Black Diamond starts with the condition in front of the technician, not a repair chosen before the visit.
The system keeps stopping
Short cycles, delayed starts, and repeated resets are operating clues—not a normal part of winter.
A sound or smell changed
Banging, scraping, electrical odors, or unusual combustion smells should be evaluated before continued operation.
What happens next
A clear handoff from phone call to field work.

Heating Repair questions
Useful details before the appointment.
01When should I call for heating repair?
Diagnosis for no heat, cool air, banging, burning smells, cycling, and rooms that never get comfortable. Call promptly when the symptom is getting worse, creating damage, or returning after a reset or temporary workaround.
02What information helps dispatch?
Share what stopped working, when it began, any sounds, smells, leaks, error codes, recent work, and whether you have already shut equipment or water off.
03Will I know the options before work begins?
The technician evaluates the condition and explains the practical next steps. Scope, availability, and pricing depend on the equipment and what the diagnosis uncovers.
