Service

We don't just install it. We keep it running.

Every system we install can be backed by a Sierra service agreement - preventive maintenance, NFPA 96 kitchen-exhaust service, and 24/7 emergency dispatch. One accountable mechanical partner for the life of the building.

Our process

From install to ongoing service.

Award the project, then keep the same team on preventive maintenance - no handoff to a third-party service company.

  1. Plans & takeoff

    Send PDF or DWG. Our estimators measure in-house - budgetary numbers in 4 business hours.

  2. Hard bid & award

    Itemized scope, exclusions, and alternates in 5 days. Submittals within 10 days of NTP.

  3. Self-perform install

    W-2 crews and our fab shop. One PM, one schedule, no layered subs on core scope.

  4. Closeout

    TAB, O&M manuals, as-builts, and warranty package - turnover ready for your GC closeout.

Three tiers. One standard.

Choose the cadence your equipment and runtime demand. Every tier is self-performed by Sierra crews - never subcontracted - with a written condition report after each visit.

The sub who built it
is the sub who maintains it.

No re-learning your building. No finger-pointing between installer and service company. The crew that fabricated and installed your mechanical scope is the crew that keeps it running.

01
Protect the warranty.
Documented preventive maintenance keeps manufacturer warranties intact and extends equipment life past its rated service window.
02
NFPA 96 compliance.
Restaurant grease-duct and hood service on the schedule your fire marshal and insurer require - logged, dated, inspection-ready.
03
24/7 when it matters.
Managed-tier clients get round-the-clock emergency dispatch. A walk-in cooler or rooftop unit down at 2am is a phone call, not a crisis.
04
One partner, every site.
Multi-site operators get one asset log, one account manager, and one number across the whole portfolio - California-wide.
