Temperature Fluctuations That Risk Your Inventory

We frequently encounter fluctuating temperatures in commercial refrigeration units, and it often goes unnoticed until the damage is done. That is to say, perishable inventory can spoil quickly if consistent cooling is not maintained. Consequently, this impacts not only your products but also your bottom line.

We’ve found that airflow obstruction and sensor misalignment are two major culprits. Moreover, when the load is uneven or doors are frequently opened, the temperature becomes unstable. In addition, many businesses fail to calibrate thermostats regularly, which leads to false readings. Therefore, if your food or beverages aren’t staying at safe temperatures, it’s not just a minor glitch—it’s a sign you need professional support. Our recommendation? Address these issues early to avoid operational setbacks. For high-priority cases, we suggest using expert help in commercial refrigeration services in Calgary to ensure your stock stays safe.

Ice Buildup in the Wrong Places

We often see businesses dealing with unexpected ice accumulation inside their units. In other words, this isn’t just about frost—it’s ice forming where it shouldn’t, such as on fans, evaporators, or vents. As a result, airflow gets blocked, which reduces efficiency and increases strain on the compressor.

What many don’t realize is that ice buildup is usually a sign of hidden airflow issues or a malfunctioning defrost cycle. Above all, this can become a long-term risk if left unchecked. Similarly, improperly sealed gaskets can allow moisture to seep in, feeding the problem. That’s why if you see ice where there shouldn’t be any, it’s time to act fast. Proper inspection and cleaning are key. And when this issue begins affecting cooling reliability, air conditioning repair in Calgary might also be necessary for systems that work in tandem.

Door Seal Failures That Cost You Money

When door seals weaken or break, we notice that customers experience a sharp rise in energy consumption. Therefore, even though the fridge appears functional, the compressor ends up working overtime. To clarify, that extra effort leads to higher utility bills and faster wear on mechanical components.

We always inspect seals during maintenance visits because they often get overlooked. For example, if staff members frequently slam doors or leave them ajar, the rubber gaskets can lose shape. Likewise, cleaning products with harsh chemicals can damage the seal’s integrity. To protect your investment, check the seal resistance periodically using the dollar bill test. If the paper slips out easily, your fridge is leaking cold air. Fixing this simple issue can save a surprising amount of money over time.

Evaporator Fan Problems You Shouldn’t Ignore

One of the most common service calls we respond to involves failing evaporator fans. Consequently, when these fans stop working properly, the entire cooling system suffers. In other words, cold air stops circulating, and your fridge develops hot spots where goods can spoil.

Above all, ignoring a faulty fan often leads to more serious damage like ice buildup or motor burnout. During inspections, we sometimes find fans clogged with debris or operating at inconsistent speeds. Likewise, noisy or vibrating fans signal deeper electrical issues. We encourage business owners to pay attention to these subtle changes in performance. Early intervention prevents costly outcomes. If airflow seems off or certain shelves aren’t staying cool, reach out. In those cases, a technician should examine whether the fan is functioning as intended or if deeper servicing is required.

Overloading That Reduces Performance

Many owners make the mistake of overstuffing their fridges, not realizing it limits effectiveness. That is to say, commercial units rely on proper airflow between items to maintain an even temperature. However, when overloaded, air circulation becomes restricted, and certain zones grow warm.

For instance, placing boxes directly in front of vents blocks the cooling path. Similarly, storing items too closely on shelves limits cold air distribution. We understand it’s tempting to make use of every inch, especially during peak times. But overloading has consequences you might not feel until it’s too late. To maintain cooling efficiency, space items properly and avoid stacking them against the evaporator panel. If you suspect this issue might be happening at your location, it may be time to contact us for a full performance check.

FAQs

What are the most noticeable signs of a commercial fridge malfunction?

Some signs include fluctuating internal temperatures, unusual noises, ice buildup, or doors not sealing properly. These issues often show up in daily operations and can affect your stored products.

How often should I have my commercial refrigerator serviced?

We suggest a preventative maintenance check at least every six months. This way, small issues are caught before they evolve into costly breakdowns.

Can a faulty door seal really affect my electricity bill?

Absolutely. A damaged door seal lets cold air escape, causing the compressor to work harder. This raises energy consumption significantly.

Is ice buildup a serious issue, or just cosmetic?

Ice buildup is more than cosmetic. It indicates airflow or defrost cycle issues that can strain your equipment and risk product spoilage.

What should I do if certain shelves aren’t cooling properly?

Start by checking airflow and whether items are obstructing vents. If the issue continues, a professional should inspect the fan and internal components.
