Boilers, rooftop units and gas piping

Seasonal service on a set checklist, adjusted to the equipment, with a written report after every visit, for one building or a portfolio.

What our maintenance visit covers

  • Rooftop units, before each season. Heating-season checklist: gas supply and venting, combustion air, burner and ignition, heat exchanger inspection at start-up, combustion analysis, safety controls, blower and drive, electrical readings, condensate. Cooling-season checklist: filters and airflow, condenser fans, coil inspection, condensate drainage, electrical readings, controls and economizer, refrigerant circuit and charge, compressor operation, high- and low-pressure safeties.
  • Boilers. Each boiler has its own schedule, because some run all year and others only in the heating season.
  • Filter and belt visits between seasons.
  • Coil cleaning, scheduled as a separate service day, by the method the coil’s construction requires.
  • A written report after every visit: results, readings, deficiencies and recommendations.

Diagnostics and repairs are quoted separately.

New installations, additions, extensions and retrofits of gas piping for commercial equipment, quoted as separate projects.
