Your thermostat says it’s 72 degrees.
So why does your restaurant still feel sticky?
Customers are uncomfortable. Employees are sweating through a busy dinner rush. Your air conditioner seems to run constantly, yet the dining room still feels humid.
If this sounds familiar, the problem may not be the temperature—it may be Florida restaurant humidity.
Florida’s climate makes controlling humidity much more challenging than simply cooling the air. While your HVAC system is designed to regulate temperature, keeping indoor humidity under control requires proper equipment, airflow, ventilation, and regular maintenance. Ignoring excess moisture can affect customer comfort, employee productivity, energy costs, and even the performance of your commercial refrigeration equipment.
Why Florida Restaurant Humidity Is Different
Restaurants in Florida face challenges that businesses in many other states simply don’t experience.
Warm temperatures, frequent rain, and naturally high humidity mean outdoor air contains large amounts of moisture almost year-round. Every time exterior doors open, humid air enters the building. Kitchen exhaust systems also remove conditioned air, requiring make-up air to replace it. If these systems aren’t properly balanced, even more moisture can enter the restaurant.
One of the most important measurements is relative humidity, which compares the amount of moisture in the air to the maximum amount the air can hold at a given temperature. Most commercial buildings are most comfortable when the humidity level stays between about 40% and 60%.
When indoor humidity rises above that range, the building may still feel warm and sticky—even when the thermostat shows the desired temperature.
Your Thermostat Doesn't Tell the Whole Story
Many restaurant owners assume that if the thermostat is set correctly, the HVAC system is doing its job.
Unfortunately, that’s not always true.
A thermostat primarily measures temperature. Unless your system includes humidity monitoring, it doesn’t tell you how much moisture is in the air.
That’s why two restaurants can both be set to 72 degrees, yet one feels comfortable while the other feels damp and uncomfortable.
When humidity is too high, moisture remains suspended in the indoor air. As a result, employees and customers don’t cool off as efficiently, making the space feel warmer than the thermostat indicates.
Turning the thermostat down a few more degrees usually isn’t the answer. If the underlying humidity problem isn’t addressed, you’ll simply increase energy consumption without significantly improving comfort.
How Excess Humidity Affects Restaurants
High indoor humidity impacts much more than comfort. It can affect nearly every aspect of restaurant operations.
Customer Comfort
Customers notice when a dining room feels humid.
Sticky air can make the restaurant feel uncomfortable even when the air conditioning is running. Guests may shorten their visit, order less, or leave with a poor impression of the overall dining experience.
Employee Comfort
Restaurant kitchens already generate significant heat. Add excess humidity, and employees often feel even hotter.
Uncomfortable working conditions can reduce productivity, increase fatigue, and make busy shifts more difficult for kitchen staff.
HVAC Performance
Your air conditioner naturally removes some moisture as it cools the air, but cooling alone doesn’t always provide adequate dehumidification.
Several HVAC issues can prevent your system from effectively controlling moisture, including:
An oversized HVAC system that cools too quickly without removing enough moisture
Dirty evaporator coils
Restricted airflow
Poor maintenance
Air leaks in the duct system
Commercial Refrigeration
Excess humidity also affects commercial refrigeration systems.
Walk-in coolers, walk-in freezers, reach-in coolers, and ice machines all work harder when surrounding air contains excessive moisture.
Higher humidity can contribute to:
More condensation
Frost buildup on evaporator coils
Longer compressor run times
Increased energy use
Additional wear on refrigeration components
Keeping humidity under control doesn’t just improve comfort—it can also help protect expensive refrigeration equipment.
Indoor Air Quality
Excess moisture creates conditions that can negatively affect indoor air quality.
Persistent humidity may contribute to mold growth, mildew, unpleasant odors, and condensation around windows, ceilings, and equipment. These issues not only affect employee and customer comfort but can also create additional maintenance concerns over time.
Common Causes of Indoor Humidity Problems
Humidity issues are rarely caused by one piece of equipment alone.
Instead, they’re often the result of several systems working together.
Common causes include:
Improperly sized or oversized HVAC equipment
Dirty HVAC coils and filters
Poor airflow
Leaking ductwork
Kitchen exhaust systems that aren’t operating correctly
Make-up air systems that aren’t properly balanced
Refrigeration equipment generating excess heat
Deferred HVAC maintenance
Because these systems interact with one another, solving humidity problems usually requires evaluating the entire building—not just replacing an air conditioner.
How Restaurants Can Better Control Florida Humidity
The good news is that humidity problems can often be improved without replacing your entire HVAC system.
Restaurants can better manage Florida restaurant humidity by:
Scheduling regular HVAC inspections and preventative maintenance
Cleaning coils and replacing filters
Monitoring relative humidity in addition to temperature
Keeping kitchen exhaust and make-up air systems properly balanced
Repairing refrigerant leaks and airflow problems promptly
Considering commercial dehumidification solutions where appropriate
Ensuring HVAC equipment is properly sized for the building
Addressing small maintenance issues before they become larger problems
These proactive steps help remove moisture, improve comfort, and support better equipment performance throughout the restaurant.
Don't Ignore Humidity Problems
Many restaurant owners focus on temperature because it’s easy to see on the thermostat.
However, humidity often has an even greater impact on comfort and operating costs.
Excess moisture can make customers uncomfortable, reduce employee productivity, increase energy bills, strain HVAC and refrigeration equipment, and shorten the life of critical systems.
Addressing humidity early helps create a more comfortable restaurant while protecting the equipment your business depends on every day.
Control More Than Temperature
If your restaurant always feels humid even when the thermostat appears normal, the issue may be excess Florida restaurant humidity, not simply the temperature setting.
United Refrigeration, Heating & Air helps restaurants throughout Central Florida identify and correct humidity problems involving commercial HVAC, air handling systems, kitchen exhaust, make-up air, and commercial refrigeration. Our experienced technicians evaluate how your building’s systems work together to improve comfort, reduce energy consumption, and keep your equipment operating reliably.
Whether you need repairs, routine maintenance, or a Commercial Maintenance Plan, we’re here to help.
