Heating Service

No heat? We will figure out why.

Repairs, tune-ups, and honest answers about whether a system is worth fixing. We service heat pumps, furnaces, and boilers of every brand.

Black Diamond Energy technician servicing a heating system

A cold house in January is not something that can wait. We diagnose the actual fault, quote the repair before we start, and tell you plainly when a repair no longer makes financial sense. Members get priority scheduling and reduced overtime rates.

  • No-heat calls and emergency repairs
  • Seasonal tune-ups and safety checks
  • All brands of heat pumps, furnaces, and boilers
  • Thermostat and control troubleshooting
  • Combustion and carbon monoxide testing
  • Repair quoted before any work begins

Fast response

No-heat calls go to the top of the schedule, nights and weekends included.

Real diagnosis

We find the cause instead of replacing parts until something works.

Safety first

Every visit includes a combustion and carbon monoxide check on fuel-burning equipment.

Straight advice

If the system is near the end, we will say so and show you the numbers both ways.

Frequently asked

Do you service systems you did not install?+

Yes. We work on every major brand, whoever put it in.

How much is a service call?+

We quote the diagnostic fee up front on the phone, and the repair price before we start the work. Members pay a reduced rate.

How often should heating equipment be serviced?+

Once a year, before the heating season. A yearly tune-up keeps the warranty valid and catches small problems before they become no-heat calls.
