Per square foot — Office vs. warehouse
Agreement structure may vary by building type, layout, and operational demands. Office and warehouse facilities can be evaluated differently based on the scope of support required.
Service agreement pricing and structure can be built around your facility, equipment profile, and service needs. Explore agreement options, compare against time and material service, and request pricing from Northern Weathermakers.
Northern Weathermakers structures service agreements around your facility — not a one-size-fits-all package. Agreement scope, frequency, and add-on options are tailored to your equipment profile and operational needs.
Agreement structure may vary by building type, layout, and operational demands. Office and warehouse facilities can be evaluated differently based on the scope of support required.
Service frequency can be aligned with the needs of the facility, equipment condition, and the preferred level of ongoing inspection or maintenance support.
Filters and coil cleaning are available as add-on services based on system requirements. These options can be discussed as part of the final agreement structure.
Every maintenance agreement includes a dedicated primary and secondary technician assigned to your facility — technicians who know your equipment, your building, and your service history.
Visits are scheduled in advance around your operations — no surprises, no waiting. You know when we are coming and can plan accordingly.
Service agreements provide a more structured path than purely reactive service. Agreement customers may qualify for preferred pricing and service advantages depending on facility profile, selected options, and final agreement scope.
A maintenance agreement should turn service history into decisions — not just close tickets. Coverage is written around the equipment actually in your building and how hard it runs, so the scope reflects your facility rather than a generic checklist.
Belts, bearings, filters, coils, drains, economizers, motors, and operating conditions reviewed in the context of the building — not as isolated parts on a list.
Airflow, filtration schedules, and ventilation equipment checked against how the space is actually occupied and used through the year.
Combustion items, pumps, and central plant equipment covered under the same planned rhythm, with seasonal start-up and shutdown built into the schedule.
Controls observations, sensor issues, scheduling problems, and economizer checks that quietly affect both comfort and energy use before anyone files a complaint.
Service notes that explain what was checked, what changed, and what deserves repair or budget attention — built for facility and owner conversations, not filed into a black-box ticket.
Repeated issues get separated into maintenance, repair planning, and replacement-watch equipment, so the right lane owns the next step before it becomes urgent.
The strongest commercial maintenance programs give owners and facility teams a clearer view of comfort risk, equipment condition, repair priorities, and upcoming budget pressure.
We start with the equipment you actually have and the conditions it runs in — belts, bearings, filters, coils, drains, economizers, controls, motors, pumps, and combustion items reviewed against how the building is used.
Notes explain what matters, what can wait, and what deserves repair or replacement planning. The goal is a document you can take into a budget conversation without translating it first.
Recurring visits create a rhythm for start-ups, shutdowns, filter programs, and controls observations — along with the capital planning conversations that come with aging equipment.
Both are real options. The difference is not only cost — it is whether equipment condition is discovered on a schedule you control or on the day something stops working.
| Maintenance agreement | Time-and-materials | |
|---|---|---|
| Scheduling | Visits pre-scheduled around your operations, so you know when we are coming | Reactive — a call is placed after something is already wrong |
| Technician familiarity | A dedicated primary and secondary technician who know your building and its history | Whichever technician is available that day, starting from scratch |
| Equipment records | Written findings build a service history you can act on over time | Documentation is limited to the individual repair call |
| Budgeting | Planned scope makes maintenance costs visible ahead of the season | Costs arrive unplanned, often at the least convenient time |
| Emergency support | 24/7 emergency service, with your equipment history already in view | 24/7 emergency service, without that accumulated context |
| Best suited to | Buildings where comfort, uptime, or budget predictability matter | Occasional one-off repairs on non-critical equipment |

The questions facility managers and building owners ask most often before putting an agreement in place.
A planned schedule of inspections and service tuned to your equipment and building use, covering items like belts, bearings, filters, coils, drains, economizers, controls, motors, pumps, and combustion components. Each visit produces written findings explaining what was checked, what changed, and what deserves repair or budget attention.
Visit frequency depends on your equipment, run hours, and how critical comfort and uptime are to your operation. We build the schedule around seasonal needs such as cooling start-up, heating start-up, filter programs, and high-demand periods rather than a one-size-fits-all calendar.
Rooftop units, split systems, air handlers, exhaust, pumps, boilers, chillers, ventilation, and building controls across commercial offices, schools, medical and lab environments, retail and mixed-use, industrial and warehouse facilities, and multi-site portfolios throughout Chicagoland.
Pricing is built around the facility rather than a fixed package. Square footage, building type and use, equipment count and type, equipment age and condition, service frequency, and any selected add-on options all affect the final agreement. The calculator on this page starts that proposal with the details specific to your building.
Time-and-materials service is reactive: work begins after something has already failed. An agreement puts inspections on a schedule you control, assigns technicians who know your equipment, and produces written findings that make repair and replacement planning visible before the season turns.
Maintenance agreement customers are backed by Northern Weathermakers’ 24/7 emergency service. Because the team has your building and equipment history, follow-up can start from useful context instead of starting from scratch.
