Tenant complaints in a multi-tenant office building almost always spike in the first real heatwave of the year. The phone calls start mid-morning, the property manager spends the afternoon walking floors with a thermometer, and by the end of the week someone has called an HVAC contractor for what should have been a planned tune-up in May. We see this pattern every June across office parks in Morris, Bergen, Essex, Passaic, Union, Hudson, Middlesex, and Monmouth Counties.
A summer-ready building is one where the equipment, the controls, and the tenant communication all line up before the first 90 degree day. The work is not glamorous, but it is the difference between a smooth season and three months of comfort complaints.
Walk the roof first
Most multi-tenant office buildings in this part of the state run on rooftop package units, with a smaller number on chillers and air handlers. Either way, the roof is where the problems live.
On a pre-summer roof walk we look at:
- Condenser coils on every RTU, cleaned with an approved coil cleaner, not just compressed air
- Belt tension and condition on belt-drive units, plus pulley alignment
- Economizer dampers and actuators, because a stuck-open economizer in July pulls in 95 degree outdoor air and runs the compressor flat out
- Drain pans pitched and draining, P-traps primed, secondary drains clear
- Refrigerant charge verified against superheat and subcooling, not topped off blindly
- Curb seals and roof penetrations sealed properly, no daylight visible from inside the cabinet
- Disconnect switches, electrical lugs, and contactor condition
- Outdoor air dampers set to the design minimum, not wide open from a winter heating mode that nobody reset
None of this takes long per unit. On a typical 60,000 to 120,000 square foot office building with six to ten rooftops, a thorough pre-summer service runs a day or two.
Check the controls before they embarrass you
The building automation system is where most summer comfort complaints actually originate, not the equipment itself. A few common problems we find every June:
- Cooling setpoints quietly drifted up by a degree or two after winter occupant requests, leaving the whole building running warm
- Occupied schedules still on a holiday or short-week override from months ago
- Zone sensors miscalibrated or installed in direct sun, reporting 78 degrees in a space that is actually 73
- Demand control ventilation tuned for shoulder season, bringing in too much outdoor air on humid days
- Trend logs not running, which means when a tenant calls about a hot office at 4 p.m., nobody can pull up what the zone actually did all afternoon
A pre-summer BAS review is short. Walk the schedules, verify setpoints, spot-check sensor calibration against a handheld thermometer in three or four representative zones, and confirm trend logging is on for at least zone temperature, supply air temperature, and outdoor air temperature. That last item matters when complaints start because it lets you answer questions with data instead of guesses.
Tenant comfort complaints: get ahead of the predictable ones
The same handful of complaints come in every summer. Knowing them in advance lets you triage faster:
- Corner office or window line too hot. Usually a zoning or solar load issue, not equipment failure. Worth checking blinds, glazing, and whether the zone has been overridden.
- Conference room won’t cool with full occupancy. Standard sizing assumes 1 person per 150 square feet. Pack 14 people into a room sized for 6 and the load doubles. Sometimes the answer is a supplemental ductless unit, not a service call.
- Server closet hot. Often missed in tenant comfort discussions because IT does not call the property manager until something fails. A dedicated mini-split or ducted supplemental cooling pays for itself the first time it prevents an outage.
- Hot in the morning, cold by afternoon. Optimal start strategy in the BAS is either off or tuned for winter. Easy fix once you find it.
- Specific floor warmer than the rest of the building. Worth checking if a VAV box damper actuator has failed in the closed or partly closed position.
A 14-day countdown to summer-ready
If the building is not ready and the forecast shows a heatwave in two weeks, work this list in order:
- Roof walk and visual inspection of every RTU and condenser
- Coil cleaning on every unit, including economizer and outdoor coils
- Belt, drive, and motor check
- Refrigerant charge verification with documented superheat and subcooling
- BAS schedule and setpoint audit
- Sensor calibration spot check in five or six representative zones
- Drain pan and condensate line clearing
- Filter change building-wide
- Trend log verification
- Tenant communication: a short note letting tenants know the building has been serviced and what the standard occupied setpoints are
That communication step gets skipped most often and matters most. A tenant who got an email last week saying “the building has been serviced for the season and is running normally” is much less likely to call frustrated on the first hot day.
