Running a restaurant means balancing food quality, customer comfort, and energy efficiency—all at once. While most owners focus on kitchen equipment and refrigeration, the HVAC system often gets overlooked. A poorly managed HVAC system can lead to uncomfortable dining areas, higher energy bills, and even food safety concerns.
At Buffo’s Refrigeration, we work with restaurants throughout Nevada to maintain reliable, efficient heating, cooling, and ventilation systems. Here are some of the most common HVAC mistakes restaurants make—and how to avoid them.
Neglecting Regular Maintenance
One of the biggest mistakes restaurant owners make is skipping routine HVAC maintenance. Filters, coils, and fans collect grease, dust, and debris from cooking areas, which reduces airflow and efficiency. Over time, neglected maintenance leads to higher energy costs, poor temperature control, and system breakdowns.
Scheduling biannual HVAC maintenance helps prevent unexpected failures and extends your equipment’s lifespan. Buffo’s Refrigeration offers custom maintenance programs tailored to restaurant operations, ensuring your system performs efficiently year-round.
Ignoring Air Balance Between Kitchen and Dining Areas
Proper air balance is critical in restaurants. Kitchens produce heat, smoke, and odors that need to be exhausted efficiently, while dining areas require clean, conditioned air. When the air balance is off, you may notice strong kitchen smells in the dining room or doors that are difficult to open due to pressure differences.
An imbalanced system also makes HVAC units work harder to maintain comfort, wasting energy and stressing equipment. Professional air balancing ensures proper airflow between kitchen exhaust systems and makeup air units, keeping your restaurant comfortable and odor-free.
Using the Wrong Thermostat Settings
Restaurants have unique temperature demands. Kitchens need effective ventilation and cooling, while dining rooms should remain consistently comfortable for guests. Setting thermostats too low or high to “make up” for heat in the kitchen often backfires, causing uneven temperatures and wasted energy.
Smart thermostats and zoning systems allow for precise temperature control in different areas of the building. This ensures both staff and customers stay comfortable without overworking the HVAC system.
Failing to Maintain Proper Ventilation
A restaurant’s ventilation system does more than remove smoke and cooking fumes—it also affects indoor air quality, humidity, and comfort. Poor ventilation can lead to lingering odors, increased humidity, and poor airflow that makes both staff and guests uncomfortable.
Regularly cleaning hoods, ducts, and makeup air systems improves efficiency and keeps indoor air fresh. Buffo’s Refrigeration technicians can test your ventilation balance to ensure your system meets Nevada’s health and safety standards.
Overlooking Humidity Control
Humidity plays a major role in restaurant comfort and food storage. Excess moisture can lead to mold growth, warped wood fixtures, and unpleasant smells. Too little humidity can cause dry air that affects comfort and increases static buildup.
A properly sized and maintained HVAC system manages both temperature and humidity. Regular maintenance ensures coils and drainage systems are clean and working properly to prevent moisture problems.
Installing Undersized or Oversized Equipment
Choosing the wrong HVAC size for your restaurant can cause major efficiency problems. An undersized system will struggle to keep up during busy hours, while an oversized one will cycle on and off too frequently—leading to inconsistent temperatures and higher wear and tear.
A professional load calculation by Buffo’s Refrigeration ensures your system is properly sized based on your kitchen output, dining area capacity, and building layout. Correct sizing reduces energy waste and maintains consistent comfort.
Neglecting Filter Changes
Grease, smoke, and dust from kitchen activity clog filters quickly. Dirty filters reduce airflow and make your HVAC system work harder, leading to higher energy bills and poor air quality.
Filters in restaurant HVAC systems should typically be replaced or cleaned every 30 days, depending on usage and environment. Fresh filters keep the air cleaner, extend system life, and help maintain balanced airflow.
Not Integrating HVAC with Refrigeration Maintenance
Your restaurant’s HVAC and refrigeration systems share similar environments and often impact one another. For example, excessive kitchen heat can make refrigeration units work harder, increasing energy consumption across the board.
A coordinated maintenance plan that covers both HVAC and refrigeration ensures all systems perform efficiently together—saving money and preventing downtime.
FAQs About Restaurant HVAC Maintenance
How often should a restaurant’s HVAC system be serviced?
At least twice a year—before the cooling and heating seasons. High-use restaurants may need quarterly inspections due to heavy cooking demands and grease buildup.
What’s the best temperature for restaurant comfort?
Most dining areas stay comfortable between 70°F and 74°F. Kitchens should maintain efficient ventilation and cooling to offset heat from equipment.
Can HVAC upgrades reduce energy costs?
Yes. Modern energy-efficient HVAC systems with smart controls, variable-speed fans, and proper zoning can reduce energy use by up to 25%.
