Have you ever wondered:
This blog answers all of those questions and more. It also shows you how to turn one of your building’s most operationally chaotic periods into an efficient, low-stress process.
When outside temperatures swing unpredictably between warm days and cold nights, your building’s mechanical systems are caught in the middle; they’re neither fully in heating nor cooling mode.
The result is a period of maximum operational complexity and, without the right controls in place, significant energy waste.
Equipment is being tested, adjusted, and prepared for the season ahead. Schedules are changing. Contractors are on site.
And your resident team is managing it all against a backdrop of unpredictable weather and resident comfort expectations.
In practical terms, this means:
Shoulder season is often one of the most expensive periods in the building’s calendar year—not because demand is high, but because control is low.
The energy waste during switchover is rarely visible, but it adds up fast. Common culprits include:
None of these are intentional.
They’re the predictable result of managing a complex system with limited information and automation.
Most buildings manage seasonal switchover manually—and that tends to mean imperfectly. Staff are physically checking systems and making judgment calls.
Decisions are based on short-term weather forecasts that can be wrong. And when things don’t go to plan, the fixes are reactive, time-consuming, and expensive.
Some of the constraints that most hamper multifamily buildings include the following:
Manual processes: Staff physically check systems and make adjustments, with limited visibility across the building.
Timing uncertainty: Decisions based on short-term forecasts that can change overnight, with no system to adapt automatically.
Binary system behaviour: Equipment runs in full heating or full cooling mode, but shoulder season demands something in between.
Small onsite teams: Limited bandwidth to manage the complexity and volume of tasks that switchover requires.
Comfort risk: Fear of getting it wrong leads to conservative, over-cautious decisions and unnecessary energy spend.
A well-managed seasonal switchover follows a clear sequence.
Doing all of this manually, twice a year, is a significant operational undertaking.
Parity takes this process even further by combining automation with a team of HVAC experts to reduce your workload while maximizing energy savings.
Define your expected switchover window well in advance (note any local regulatory deadlines for heating or cooling provision)
Check all relevant equipment to identify and address issues before they become problems on switchover day.
Don’t jump directly from full cooling to full heating (or vice versa) and avoid running both systems simultaneously.
Monitor conditions daily throughout the switchover period and adjust based on both internal building conditions and external temperatures
Confirm that all systems are operating correctly and record any issues identified during switchover.
Done well, this process protects tenant comfort, keeps your team in control, and prevents the energy waste that accumulates when switchover is managed reactively.
✓ Fewer reactive decisions—issues identified before they become complaints or failures
✓ Reduced energy waste—no simultaneous heating and cooling, no over-conditioning
✓ Lower risk of heating and cooling overlap—systems transition cleanly
✓ Smoother seasonal transitions—every time, across every building
✓ Better resident experience—no loss of comfort during the transition period
Seasonal switchover happens whether you’re ready for it or not.
The difference between a smooth transition and a chaotic one comes down to preparation, coordination, and the right controls.
