Heating Service Before the Cold Front

The Valley only gets a handful of hard freezes — and that's exactly when heaters fail. We repair heat pumps and furnaces, run safety inspections, and tune systems so they start on the first cold night.

What we service

Heat pump repair

Reversing valves, defrost boards, auxiliary heat strips and low-charge diagnostics on all major brands.

Furnace repair

Ignitors, flame sensors, gas valves and blower motors on gas and electric furnaces — repaired safely and to code.

Safety inspections

Heat exchanger inspection, carbon monoxide testing, gas leak checks and venting verification.

Commercial Heating

Heat pumps & furnaces for tenant spaces and small businesses

We service commercial heat pumps, gas furnaces and electric heaters in office suites, retail centers, churches and multi-tenant buildings — with safety documentation you can share with tenants or inspectors.

  • Commercial heat pump repair and defrost diagnostics
  • Gas furnace safety checks and CO testing
  • Multi-zone thermostat and control service
  • Pre-season inspections for tenant buildings
  • Written safety reports for property managers
  • Emergency heating dispatch

Seasonal tune-up checklist

A 45-minute visit each fall prevents the most common no-heat calls.

  • Test ignition sequence and safety controls
  • Inspect heat exchanger and check for CO
  • Verify temperature rise and airflow across the coil
  • Tighten electrical connections and check amp draw
  • Test thermostat calibration and staging
  • Replace or inspect filters and clear the drain

Book in October–November for the shortest wait.

Schedule heating service

Repairs, safety checks or a seasonal tune-up — we'll confirm a window.
