Your Heating System Is Running. But Is It Ready for Winter

When the first cold mornings arrive, facilities teams shift their attention from cooling to heating. Boilers fire up, air handlers change modes, and systems that have been sitting idle for months are put back to work.

A successful startup is a good sign. But just because equipment turns on doesn't mean it's ready for another Minnesota winter. When a midwinter system failure strikes, the stakes are incredibly high-emergency repairs can easily cost triple the rate of planned maintenance, and unexpected downtime directly threatens tenant satisfaction, operational revenue, and facility safety.

For facilities leaders managing multiple buildings, fall is an opportunity to look beyond basic maintenance and ask a more important question: What are our heating systems telling us about the season ahead?

1. Look Beyond Whether Equipment Starts

A traditional fall startup includes inspecting boilers, checking burners, testing safety controls, and verifying system operation. While these are critical steps, they only tell a fraction of the story.

To prevent midwinter emergencies, facilities teams must treat the initial startup as a diagnostic baseline by looking closer at critical operational indicators:

• Micro-wear patterns: Are specific components, like pump seals or valve actuators, showing subtle signs of physical degradation?
• Efficiency drops: Is the equipment drawing more energy or fuel than it did during the same period last year to achieve the same output?
• Chronic glitches: Are minor, recurring issues from last January starting to creep back into your system logs?

Catching these baseline shifts early allows you to address developing problems on your own schedule, rather than during a January freeze.

During one fall startup at a commercial building, a Horwitz technician found that one boiler in a multi-boiler system was not operating. The building still had heat because the remaining boiler was carrying the load, so the problem had not been apparent to the building engineer.

Troubleshooting traced the issue to a failed ignition component that kept the second boiler from firing. Identifying it before colder weather arrived gave the team time to recommend repairs. Without that discovery, the building would have entered winter without its designed heating capacity or backup equipment. If the remaining boiler had failed during freezing weather, the result could have been a loss of heat, frozen piping, an emergency service call, and significant downtime.

"Just because a building has heat during startup doesn't mean the entire system is operating correctly. Part of our job is verifying that every boiler, pump, and control is ready when the building needs its full heating capacity," exclaimed Devon Schewe, Preventive Maintenance Sales Executive.

2. Pay Attention to the Shoulder Season

Fall's fluctuating temperatures create a unique, real-time stress test for evaluating building performance. When weather swings wildly between warm afternoons and freezing mornings, heating and cooling systems are forced to rapidly transition and adapt.

These rapid shifts frequently expose hidden system conflicts that go completely unnoticed during periods of predictable weather:

• Simultaneous heating and cooling: Misconfigured economizers or fighting thermostats can cause a building to waste massive amounts of energy by heating and cooling the same zone at the same time.
• Short-cycling: Rapidly changing loads can cause boilers or air handlers to turn on and off too quickly, accelerating equipment wear.
• Inconsistent zone temperatures: Stagnant air or lagging controls can leave some spaces freezing while others overheat.

Testing how smoothly your controls and automation systems transition between operating modes right now is just as valuable as confirming the heating equipment works.

3. Consider the Entire Campus, Not Just Individual Systems

For healthcare facilities, higher education campuses, and industrial operations, heating reliability is rarely about a single piece of equipment. It is about how fragmented systems work together across buildings with different ages, uses, occupancy schedules, and operational demands.

Managing a campus requires balancing unique structural contrasts:

• Legacy vs. Modern: Balancing a newly built, high-efficiency outpatient clinic or lab alongside a decades-old wing with completely different piping infrastructure.
• Variable Loads: Coordinating a high-density student housing schedule with the baseline thermal requirements of a nearby research facility.

A campus-wide approach helps facilities teams identify recurring systemic issues, prioritize high-risk equipment, and coordinate maintenance around actual operations. It also creates a clearer picture of where your limited resources should be focused before severe weather hits.

Consider a hospital campus with a newer outpatient pavilion and an older inpatient wing. The pavilion's heating controls respond quickly to changing schedules, while the older wing has different piping and a slower warm-up cycle-and it needs reliable heat around the clock. If both buildings rely on shared plant equipment, a startup check at the boiler room alone may not show how well heat is reaching each space under its actual operating conditions.

Reviewing the campus as a whole helps the service team connect the pieces: how the plant, pumps, controls and building-level systems respond to different demands. That broader view can reveal where a recurring comfort issue or equipment strain is coming from, help prioritize repairs, and make it easier to schedule work around patient care.

4. Turn Fall Maintenance Into Next Year's Capital Plan

One of the most valuable outcomes of a comprehensive fall inspection isn't a completed checklist. It's better long-term data.

Documenting equipment conditions right now gives facilities leaders the timeline they need to plan investments strategically. Instead of making expensive, rushed replacement decisions during a midnight system failure, you can confidently build a roadmap based on hard data:

• Which high-value assets are verifiably nearing the end of their useful life?
• Which specific repairs are becoming too frequent to justify keeping the equipment?
• Which total replacements must be prioritized in next year's capital budget?

A Better Approach to Winter Readiness

Shifting from a reactive, check-the-box maintenance routine to a strategic winter plan requires a partner who understands the operational data your buildings are already screaming out. At Horwitz, we believe preventative maintenance should do more than prepare equipment for the next season-it should help facilities teams deeply understand their buildings, anticipate operational challenges, and make informed decisions about the future.

Our service teams develop long-term familiarity with the specific campuses they support. By connecting routine maintenance observations directly with asset planning and operational priorities, we ensure you are never caught off guard. Because the absolute best time to plan for a heating system failure is long before the temperature drops.
