Building Automation & Remote Monitoring

JMI integrates remote HVAC monitoring technology into our service programs to give you real-time visibility into your building’s performance. Our monitoring platforms complement our maintenance programs by enabling remote diagnostics, automatic fault correction, and proactive technician dispatch — often before occupants even notice an issue.

Remote monitoring also provides historical performance data that our team uses to help you negotiate better utility rates and identify energy-saving grants and incentive programs.

Systems we monitor:
Building automation and controls, HVAC equipment, lighting systems, and refrigeration.

Want to add remote monitoring to your facility? Contact our team for a consultation.

Operations Analysis & Asset Management

Effective facility management starts with knowing exactly what you have and what condition it's in. JMI's Operations Analysis provides a comprehensive inventory of your HVAC assets — including makes, models, serial numbers, installation dates, locations, and current condition assessments — giving your team a clear picture for capital planning and budgeting.

We document estimated repair, replacement, and rebuild costs for each piece of equipment, so you can prioritize spending where it matters most and avoid unexpected failures.

Energy Audits & Efficiency Consulting

Rising energy costs make system efficiency more important than ever. JMI's energy audits evaluate your equipment's real-world performance against manufacturer specifications and industry benchmarks to identify opportunities for operational savings.

Our Account Managers use this data to recommend maintenance strategies tailored to your budget and operational priorities — whether that's extending equipment life, reducing energy consumption, or planning for phased replacements.

Funding & Incentive Programs

Many equipment upgrades and efficiency improvements qualify for utility rebates, energy-saving grants, and government incentive programs. JMI's team stays current on available programs in the Puget Sound region and can help you identify and apply for funding applicable to the repair, rehabilitation, or replacement of your existing systems.

Not Just Belts and Filters

Too many maintenance programs amount to little more than a technician swapping out belts and filters on a schedule. JMI takes a fundamentally different approach.

Our Planned Maintenance Programs are tailored to the specific requirements of each facility and cover all major makes and models of commercial HVAC and refrigeration equipment. Every agreement is designed around your building’s actual operating conditions — not a generic checklist.

What Our Technicians Actually Do

During every scheduled visit, JMI technicians perform a comprehensive inspection that goes well beyond your equipment’s standard O&M manual recommendations. This includes verifying refrigerant levels and pressures, testing safety controls and limit switches, inspecting electrical connections and amp draws, checking bearing and belt conditions, evaluating system airflow and temperature differentials, and calibrating thermostats and controls.

After every visit, you receive a detailed service report documenting findings, work performed, and recommendations — so you always know the condition of your equipment.

Preventive, Predictive & Condition-Based Programs

JMI offers maintenance programs at every level, from basic seasonal inspections through to full-coverage predictive maintenance using real-time monitoring data. Your Account Manager will recommend the right level of coverage based on your equipment’s age, criticality, and operating environment.
