Stop Paying the $1,500 Open Door Tax Every Year
Your Air Conditioner is Fighting a Losing Battle
Every time a delivery driver props your back door open, your bank account takes a hit. Cold air is heavy, so it falls out of your building. Warm air from the street rushes in to replace it. Your air conditioner has to work 2 times as hard to keep up.
The Math Behind Your Wasted Kilowatts
Data from the Department of Energy shows an unprotected door can lose about 3 kW of energy per hour during peak hours. That is about the same as running 3 large commercial microwaves at the same time.
In cities like Chicago, that means about $0.33 wasted every hour. In New York, it jumps to over $0.50 per hour. In hot states like Texas and Florida, the cost of cooling the sidewalk is even higher.
An air curtain stops this cycle by creating a wall of air. This fix can cut your door-related energy costs by about 40%. For a busy restaurant, that is around $1,500 in savings each year.
Stop Your Best Cooks From Quitting Over a 95 Degree Kitchen
Hiring is one of the biggest headaches for restaurant owners today. Data from the National Restaurant Association shows the industry average turnover rate is about 75% per year (source).
In fast food, that number can reach 150%. If your kitchen stays at 95 degrees, your best people will eventually leave for a cooler workplace. They take their experience and your consistency with them.
Every New Hire Costs You $5,864 in Profits
| Staffing Impact | Cost to Your Business |
|---|---|
| Losing 1 hourly employee | $5,864 in replacement costs |
| Training 3 new cooks | $17,592 in lost profits |
| Hot drive-thru window | Slower service and more order mistakes |
The National Restaurant Association reports it costs $5,864 to replace just 1 hourly employee. That money goes into recruiting and training. It also covers the lost productivity while your new hire learns your line.
An air curtain keeps cool air on your staff and the heat in the alley. A small drive-thru air curtain can keep workers near 72 degrees. If this equipment prevents just 1 person from quitting this year, it has already paid for itself.
Pass Your Health Inspection and Stop the 1 Star Reviews
Pest violations are a common reason for low grades in major cities like New York and Chicago. FDA Food Code 6-202.15 allows a properly installed air curtain as a legal barrier for your doors. The law treats it the same as a screen door.
A single fly violation can cost you fines and re-inspection fees. Even worse, 81% of diners will not return if they see a fly in your dining room (source). More than half say they posted a negative online review or social media comment about it.
One bad Google review mentioning a pest in the dining area can hurt your weekend revenue. An air curtain creates an invisible barrier that blocks 99% of flying insects without chemicals (source).

Select the Best Equipment for Your Layout
You must match the equipment to the specific opening to avoid wasting your investment.
| Location | Primary Goal | Recommended Features | Recommended Berner Unit |
|---|---|---|---|
| Back delivery door | Stop pests and heat | High velocity and NSF 37 rating | Berner SLC Series |
| Main guest entrance | Protect AC and comfort | Quiet and low profile | Berner Architectural Series |
| Drive thru window | Block fumes and humidity | Fast acting sensors | Berner DTU Series |
| Walk in cooler | Prevent ice and fog | Cold storage rating | Berner CLC08 |
The Heavy Duty Choice for Your Back Door
Your delivery entrance is your biggest money pit. For doors up to 10 feet tall, the Berner SLC Series is the industry standard. It provides the high velocity air stream needed to meet NSF 37 standards for pest control. This unit is built to handle the constant traffic of food deliveries without burning out the motor.
Specialized Protection for Windows and Coolers
For drive thru areas, the Berner DTU Series is small enough to fit above a standard service window. It blocks car exhaust from entering your kitchen and keeps your staff comfortable. In the back of the house, the Berner CLC08 stops moisture from turning into ice on your walk in freezer floor. This prevents slips and keeps your refrigeration bill low.
Avoid the 2 Most Expensive Buying Mistakes
1. The Mounting Height Trap. Measure from your floor to the very top of the door frame. If your door is 8 feet tall, you need a unit rated for 8 feet or more. If the air wall does not hit the floor, flies will crawl right under the barrier.
2. The Voltage Headache. Check your breaker box before you buy. Most commercial units need 208 or 240 volts. A standard 120 volt wall outlet will not work. If you have to hire an electrician to run a new line, your cheap unit just became a $500 problem.
Do not try to save money by buying a residential fan. A busy restaurant door can open 100 times or more in a single shift. A home grade motor can burn out in less than 3 months. Stick with commercial equipment built for the heat and grease of a professional kitchen.
Your 3 Point Door Audit
Do this tonight after the dinner rush to see how much money you are losing.
1. Check the Temperature. Stand 5 feet away from your front door. If you feel a draft, your AC is leaking onto the sidewalk.
2. Count the Flies. Look at your back door during a delivery. If you see more than 2 flies, your current pest strategy is failing.
3. Inspect Your Freezer. Look for ice or fog on your walk in doors. This means your compressor is working too hard.
Stop paying the open door tax. Investing in a professional air curtain can pay for itself through savings and more stable operations.
