From 10 Complaints a Month to Zero Thanks to This Upgrade

Every property manager dreads repetitive maintenance calls especially when they start stacking up. In one of our managed buildings, we were averaging 10 tenant complaints per month, and most pointed to the same culprit: bathroom exhaust fans. They were loud, ineffective, and so annoying that tenants avoided using them altogether. That led to moisture buildup, peeling paint, and mold around vents creating bigger problems down the line.

Then we made one smart change: we installed humidity-sensing, ultra-quiet exhaust fans in every unit. No switches, no noise, just quiet efficiency. Within days, complaints dropped to zero and tenant satisfaction climbed. This story shows that sometimes a single, well-targeted upgrade can reinvent a property’s performance. Here’s how we did it.

Bathroom Fan Failures: A Hidden Problem

Loud, Ineffective, Ignored

When the fans are noisy, tenants simply don’t use them. Tenants reported being unable to sleep or focus because of the fan noise and often left them off to avoid the disturbance. Without proper ventilation, moisture stayed put, damaging walls and finishes.

Moisture Buildup and Mold Risk

Hidden moisture fueled mold growth around exhaust vents. We saw peeling paint on ceilings and walls and signs of mildew in bathroom corners. These issues demanded frequent repairs and posed liability concerns.

Maintenance Burden

Each broken fan required a work order, a tech visit, and replacement parts. With ten failures a month, costs quickly ballooned. Worse, tenants lost confidence in the property’s upkeep.

The Smart Solution: Humidity-Sensing, Ultra-Quiet Fans

How These Fans Work

• Automatic operation: They activate when humidity exceeds a preset level, then shut off automatically.
• Ultra-quiet design: Sone ratings under 1 make them virtually silent, even during long cycles.
• No switches, no tenant effort required.

Performance vs. Older Units

Older fans were loud (2–3 sones) and manual. In contrast, our new fans run quietly, trigger automatically after showers, and preserve air quality behind the scenes with no tenant reminders needed.

Immediate Results and Tenant Feedback

Zero Maintenance Calls

After installing the new fans, maintenance requests dropped from 10 per month to zero, and they have stayed at that level. That translates into significant savings and more stable scheduling for property staff.

Cleaner Air and Better Finishes

The constant airflow prevents lingering moisture, keeping walls and ceilings dry. That protects finishes and reduces mold risk a win for both tenants and maintenance teams.

Tenant Appreciation

During lease renewals, tenants commented: “I didn’t even notice it until I realized the bathroom always smells fresh.” These subtle enhancements often stand out once tenants recognize the improved comfort and peace.

Time and Cost Savings for Property Teams

Work Orders Eliminated

With no more fan complaints, maintenance teams freed up hours every week time they could dedicate to upgrades, inspections, or tenant support.

Fewer Emergency Fixes

No unexpected fan breakdowns meant no hassle or cost for tenant repositioning or re-cleaning.

Staff Efficiency Up

Hours once spent responding to calls are now invested in preventive tasks and quality improvements making the entire portfolio run more smoothly.

Why One Targeted Upgrade Matters More Than a Full Remodel

High ROI, Low Disruption

Installing a smart fan costs just $50–$150, with minimal install time. A few hundred dollars transformed performance, doubled tenant comfort, and eliminated dozens of repair calls.

Fast Installation, Minimal Tenant Disruption

Most fans are swapped in under two hours. We notify tenants in advance, handle all cleanup, and restore utilities quickly without relocating anyone or forcing unit downtime.

Targeted Solutions Solve Systemic Issues

While full renovations are expensive and time-consuming, this upgrade tackled a common and recurring pain point with speed and precision.
