Michigan school districts that spent ESSER funds on HVAC upgrades between 2021 and 2024 now own a patchwork of new and legacy equipment with no dedicated maintenance budget to cover it. A phased preventive maintenance plan tied to equipment age and failure probability is the practical answer. Samco Facilities Maintenance works with K-12 facility teams across Wayne County, Oakland County, and Macomb County to build PM programs that fit what a district can actually fund.

Why Post ESSER School HVAC Is a Quiet Crisis
Federal ESSER money moved fast, and a lot of it went to HVAC. Michigan districts installed new rooftop units, energy recovery ventilators, and upgraded controls during a three-year window. That work was real and the indoor air quality improvements were measurable. The problem is what comes next.
ESSER funding is gone. Most districts received no recurring operating dollars tied to the new equipment, which means the maintenance bill for those units now competes with buses, textbooks, and staffing. The legacy boilers, fan coil units, and exhaust systems that did not get replaced sit right next to the new equipment, and the facility director manages both with the same strained budget.
Districts across Southeast Michigan are realizing that a $400,000 ESSER rooftop replacement program generates roughly $40,000 a year in PM requirements going forward. That number does not appear in any grant paperwork. It shows up in the first hot September when three of the new units trip on a refrigerant fault and no service agreement is in place.
School boards are not ignoring this. They are unsure how to prioritize when both the capital budget and the operating budget are under pressure. A phased PM approach built around actual equipment age and failure probability gives facility directors a document they can take to a superintendent and defend.
A Phased PM Plan for Aging K-12 Equipment
Phased PM for school districts works differently than a standard commercial PM contract. A manufacturer distributes their equipment load across four buildings with similar units. A school district runs thirty buildings with equipment spanning 1989 to 2024 in the same mechanical room.
The planning starts with a full equipment inventory sorted by age, condition, and criticality. ESSER units get a standard PM cadence because they are under warranty and the manufacturer may require documented service to keep the warranty valid. Legacy equipment gets triaged: units with less than three years of estimated useful life go on a capital replacement list, not a PM list, because pouring PM money into them returns nothing.
Here is what field work actually shows in Michigan schools. Every gym unit in a building constructed before 2000 that was not replaced with ESSER funds has a corroded coil and a bypassed economizer. Not some of them. All of them. The corrosion is from humidity cycling during basketball season when the doors open and close a hundred times a day, and the bypassed economizer is from a maintenance shortcut that was taken ten years ago and never documented. Neither of those facts appear in any asset register.
A realistic phased plan for a 15-building district in Wayne County or Oakland County looks like this: Tier 1 covers units under five years old with full PM including filter changes, coil cleaning, belt inspection, and controls calibration. Tier 2 covers units five to fifteen years old with PM focused on failure prevention, meaning refrigerant charge checks, contactor and capacitor replacement, and economizer actuator inspection. Tier 3 covers units over fifteen years old with inspection only and a capital replacement recommendation attached. That document is what a school board actually needs to make a budget decision.
The Michigan Angle: Oakland, Macomb, and Wayne County School Footprints
Michigan school districts are not small building operators. Oakland County districts like Bloomfield Hills, Pontiac, and Auburn Hills run large high schools with 200,000 square feet or more under a single roof. Macomb County districts in Sterling Heights and Warren run aging elementary buildings that were built in the 1960s and never had a serious mechanical upgrade until ESSER. Wayne County includes Detroit Public Schools Community District, which manages one of the largest K-12 facility portfolios in the Midwest.
The common thread across all of them is a facility director who covers multiple buildings with a small in-house maintenance crew that handles lights, plumbing, and basic HVAC but cannot perform refrigerant work or commission a new controls sequence. That gap is where a commercial HVAC contractor with K-12 experience fills in.
Michigan Mechanical Code requirements apply to school boilers and HVAC systems just as they do to commercial buildings. CSD-1 boiler testing is a legal requirement, not optional, and districts that let that slip during the ESSER rush are now behind. Samco Facilities Maintenance covers that compliance gap as part of a standard service agreement. A district in Dearborn we have worked with since 2009 found three boilers past their CSD-1 test date during our first site walk, and getting them current took priority over everything else on the PM list.
Summer Shutdown Replacement Windows
Summer shutdown is the only viable window for major HVAC work at a K-12 facility, and it is shorter than most facility directors assume. June 15 to August 10 is realistic. Before June 15, graduation and summer school occupy the buildings. After August 10, staff return and buildings need to be operational.
To use that window well, a district needs to do the following:
- Complete equipment triage by March. Know which units are targeted for replacement before the school year ends. Any decision made in June costs money in July because lead times on commercial rooftop units run eight to fourteen weeks.
- Issue the service agreement by April. Contractors who are already under contract in April can pre-order equipment and hold slots. Contractors who are called in June are working on someone else’s schedule.
- Stage crane access by building type. Flat-roof buildings in Michigan school districts often have roof access issues that are not visible until the crane shows up. A pre-job site walk with the HVAC contractor and the crane operator in May prevents a one-day job from becoming three.
- Sequence new and legacy work separately. New unit installation and legacy PM are two different scopes. Running them in parallel on the same building with the same crew leads to incomplete work and warranty gaps.
- Plan controls commissioning as a separate task. A new RTU connected to an existing BAS needs commissioning time. Budget two to four hours per unit for that work and do not skip it. An uncomissioned unit will run, but it will not meet ASHRAE 62.1 ventilation rates.
- Confirm refrigerant type before ordering. New commercial RTUs in 2025 and 2026 ship with A2L refrigerants in some product lines. Plan for technician certification gaps before the unit arrives on the roof.
- Set a punch list deadline of August 1. Items remaining after that date carry a real risk of incomplete work when school opens. Build the deadline into the contract.
How Samco Works With Michigan Facility Teams at Schools
Samco Facilities Maintenance has served Michigan K-12 and higher education facility teams since 1997. Our technicians are EPA 608 Universal Certified and NATE certified, and we carry a BBB A+ rating. We understand that school facility directors answer to a superintendent, a board, and parents, which means the documentation we provide has to hold up in a public meeting, not just in a maintenance log.
Our process for a school district engagement starts with a full equipment inventory, a condition scoring per unit, and a written PM scope with annual cost per building. We separate warranty-covered equipment from legacy equipment in the proposal so the decision-makers can see the full picture. We flag CSD-1 compliance status on every boiler as a line item with a due date, not a footnote. And we provide a summer shutdown schedule in April so the district can plan crane access and permitting without calling us in a panic in June.
For districts with CMMS platforms, we feed completed work orders in whatever format the system accepts. For districts without one, we provide a quarterly summary report that meets the documentation standard a state auditor would expect. Call (734) 838-6300 or visit our commercial HVAC service page to start a conversation. You can also review our preventive maintenance programs designed for multi-building operators.
Frequently Asked Questions
What happens to school HVAC after ESSER funds run out?
Districts own the equipment outright but most received no recurring maintenance funding tied to it. The PM cost for new rooftop units runs roughly 10 cents per square foot per year. Without a service agreement, those units will run on deferred maintenance until the first major failure, which typically costs three to five times what a PM contract would have cost over the same period.
Can Samco serve Michigan school districts directly?
Yes. Samco Facilities Maintenance works with K-12 facility teams in Wayne County, Oakland County, and Macomb County. We provide site assessments, annual PM contracts, summer shutdown replacement planning, and CSD-1 boiler compliance services. Our EPA 608 and NATE certifications meet the technical requirements most districts specify in their vendor qualifications.
How does phased PM work for a school with aging HVAC?
We sort equipment into three tiers by age and condition. New ESSER units get full PM to protect warranties. Mid-age units get failure-prevention PM focused on the parts most likely to fail. End-of-life units get inspection only plus a capital replacement recommendation. That structure lets a district direct PM spending where it returns the most value instead of spreading it evenly across equipment with different remaining useful lives.
Do you support summer shutdown HVAC replacement at schools?
Yes. We scope and schedule summer replacement work starting in April so equipment can be ordered ahead of lead times and crane access can be planned. Our standard process includes pre-job site walks in May, installation during the June through August window, controls commissioning, and a punch list deadline of August 1 to make sure the building is ready before staff returns.
