Emergency Response and SLAs

Priority accounts can set response time targets for critical areas. We coordinate after-hours access, rooftop safety, crane timing, and tenant communication so issues are contained and resolved quickly.

Preventive Maintenance Program

A recurring program reduces outages and keeps energy spend predictable. Typical visits include filter changes, belt and bearing checks, coil cleaning, electrical and control checks, refrigerant verification, drain service, and airflow readings with a signed task list. If you want a simple way to stay on schedule, set up a recurring maintenance program with our team.

Ventilation and IAQ Upgrades

We review outside air rates, ERV settings, and economizer function, then balance systems so ventilation meets design while controlling humidity and noise. Upgrades include sensor placement, damper repairs, and control sequences that fit your space type.

Controls and BAS Integration

We tune schedules, alarms, and trend logs and integrate new equipment with existing BAS where practical. Support includes point mapping, setpoint strategy, and fault diagnostics to reduce nuisance calls.

Energy and Capital Planning

We provide lifecycle cost comparisons, right-size replacements, and help align scope with utility incentives where available. Proposals include timing, rigging or crane needs, and expected impact on comfort and consumption.

Critical Environments

Server rooms, labs, and storage areas require stable temperature and humidity. We service precision cooling, add redundancy where needed, and document alarms and setpoints so responses are consistent across shifts.

Documentation and Compliance

Expect asset lists with nameplate data, service logs, start-up checklists, sequence-of-operations notes, and refrigerant documentation that supports warranty and record keeping.

Safety and Site Readiness

Before work begins, we confirm roof access and tie-off points, electrical lockout, traffic control if a crane is used, and a clear path for equipment movement to protect tenants and staff.

Our Process: Site Survey to Verification

Site survey
Equipment list and nameplate data, filter sizes, access and safety review, ventilation and airflow checks.
