Three Most Common Walk-In Cooler Problems

walk-in cooler problemsWalk-in coolers are one of those appliances where we just expect them to work. They are the cornerstone of business operations for restaurants, cafeterias, and other food-related businesses. When they break down, and they do break down, it can be a little nerve-wracking to diagnose the issue without immediately calling in a professional. Modern Air & Refrigeration of Sarasota would like to equip you with the know-how of how to deal with the three most walk-in cooler problems continuing our drive to educate our followers.

Walk-in Cooler is Freezing

Our first item on the most common walk-in cooler problems list is a common issue that might seem antithetical to coolers. Some business owners experience the unpleasant problem of a walk-in cooler freezing up. The ice is usually concentrated around the evaporator. To remedy the issue, first, melt the ice off the evaporator and make sure the evaporator fan is rotating correctly. The ice issue might also be caused by a dirty coil and drain line. Make sure these areas are clean and clear for proper ventilation preventing ice formation.

Walk-in Cooler Temperature Fluctuations

This is possibly the worst problem in our walk-in cooler problems list. Uneven temperatures can lead to dangerous conditions as sub-cooled food can be dangerous to your customers. There are several causes that can lead a walk-in cooler to fluctuate in temperatures. Check subcooling, superheat, and operating pressure to ensure they are all within regular parameters. These numbers can be found in your operator manual. Most often, the cause might be as simple as the door not sealing correctly due to age or disrepair. The last culprit that might cause uneven temperatures is the compressor. If it turns off before the set temperature is reached then it might be time for a replacement.

Walk-in Cooler Problems: Completely Dead

The most jarring of all walk-in cooler problems is when the unit is completely non-functional. The first thing you want to do is not panic. Check your electric connection and make sure it is connected. The unit is sometimes connected to a disconnect as well, ensure this has power. A completely nonoperational cooler is in most cases either an easy fix via reconnecting power or a tough nut to crack as you might have to call in a professional. Electric issues are best left for those with experience in the deep mechanics of a walk-in cooler.

Walk-in Cooler Maintenance Tips

walk-in coolerA walk-in cooler is a critical major investment for any business in the food service industry. A faulty or broken cooler could lead to a stoppage of business operations and a loss of major inventory. This would be disastrous for operations. This is why it’s crucial that you keep your walk-in cooler in great shape to avoid any of these problems from plaguing your business. Besides hiring walk-in cooler experts like Modern Air and Refrigeration of Bradenton, there are several steps you can take to increase the lifetime of your cooler.

Walk-in Cooler Condensing Unit

All the components of your walk-in cooler are important but some more so than others. None are as significant as your condensing unit. Your walk-in cooler’s condensing unit consists of three pieces; the compressor, the condensing coil, and the condensing fan motor. Together they are the workhorses of your walk-in cooler. They use coolant to keep the temperature low and your goods properly refrigerated. It’s highly recommended that at least twice a year you shut off the power to your cooler and clean the condensing unit. This can be accomplished by either vacuuming around the unit or reversing the air flow. The latter is more complicated but more effective.

Monthly Cleaning Your Walk-in Cooler

The purpose of a walk-in cooler makes it unavoidable that it will get dirty. Food spills, dirty footprints, and just the general foot traffic these coolers see make it a favorable environment for bacteria and other contaminants to develop. Cleaning a cooler requires a different approach than your home fridge. Certain cleaners and chemicals can damage the surfaces of your cooler. Soap and water are the recommended tools to clean your cooler. Due to the gentleness of these solutions, it’s extremely recommended that you clean your cooler at a minimum once a month.

Walk-in Cooler Yearly Inspections

The complexity of your walk-in cooler’s operations will eventually necessitate the assistance of professionals. The costly nature of a cooler breakdown makes it prudent for every business owner to take the necessary preventative steps in ensuring a walk-in cooler emergency never befalls their business. A walk-in cooler contractor should be local with 24/7 support availability. Every second your cooler is malfunctioning is more of your inventory lost increasing the cost of a breakdown exponentially.

Air Sealing Your Home: Summer AC Preparations

air sealingSummer is just around the corner. And summer temperatures bring summer electric bills. Your AC system represents a significant percentage of that electric bill. Consequently one of the biggest causes of that ballooning bill is air leaks around your home. Air sealing is a critical component of reducing AC heating and cooling waste, especially in extreme temperatures. Modern Air and Refrigeration of Sarasota is here to help! We have gathered information on the consequences of air leaks, with remediation methods to help your air sealing efforts.

The Effect of Air Leaks

Heating and cooling can account to up to 54% of your energy consumption, depending on your home, air leaks may represent more than half of that cost. Air sealing your home is not just a money-saving endeavor, however. Air leaks can damage your home’s structural integrity over time. The constant exposure to the outside air can lead to the development of mold, water damage and pest infestations.

Detecting Air Leaks

Now that we have established the dangers of air leaks, let’s move on how to rectify the problem in your home. Air sealing cannot begin without properly detecting air leaks. Homeowners have several options from free to moderate cost detection methods. The quickest way to test for air leaks is by using your hand. Place it on corners or other outside facing entrants in your home such as doors or windows and feel for a breeze. Candles can also be used for detecting smaller leaks such as around electrical outlets and light fixtures. For the technically apt, an air leak detector might be a good investment for a more accurate air leak assessment. The most accurate air detecting method is to hire an HVAC contractor to perform a blower door test.

Air Sealing Your Home

Air sealing around your house is not a clear-cut process. Different sized leaks call for different methods to seal them. Spray foam is excellent for ceiling around pipes, plumbing, wall joints, and other areas less than 5 inches in length. The exterior of the home can be sealed with rigid foam which is more resistant to the environment and can be applied to the roof, a major source of air leaks. For smaller leaks such as cracks and gaps less than a quarter inch wide, caulking is the preferred method for air sealing. Doors and windows represent a different challenge as they have components that move frequently. Weather stripping is the recommended method to keep windows and doors sealed against leaks.

3 Signs You Need a New AC Thermostat

3 Signs You Need a New AC Thermostat

AC thermostatYour AC thermostat is the part of your HVAC system that sees the most traffic. It’s the steering wheel to the car that is your AC system. It’s understandable then to extrapolate that if your thermostat is not functioning or functioning sub-optimally your car is in trouble. To a regular homeowner, non-obvious signs that a thermostat might be malfunctioning may go unnoticed. As a matter of fact, unless the thermostat is completely off most homeowners assume it’s working correctly. This is a common misconception. In this Modern Air & Refrigeration article, we will explore three most common signs that your AC thermostat might be in need of repairs or replacement.

AC Thermostat Unresponsiveness

The quickest way to judge the effectiveness of your AC thermostat is its responsiveness. This can be ascertained by paying attention to the ticking sound you hear when you drastically change the temperature in your home. Listen closely to hear how quickly the click comes after a temperature change. Anything more than 3 to 5 seconds points to a slow to respond or non-responsive thermostat. The size of an AC thermostat makes it unideal to open to diagnose the issue. If you notice unresponsiveness, be sure to contact your local Sarasota HVAC contractor for a professional diagnosis.

Short Cycling HVAC System

This next AC fault is a little more subtle than the easy to identify click from an AC thermostat. As a matter of fact, this issue is often mischaracterized as the entire AC malfunctioning but the culprit is more often than not the thermostat. Your HVAC system might be failing to complete a full heating and cooling cycle due to improper temperature readings from your thermostat. Known as short cycling, the half performed cycles will leave your home feeling unpleasant. This is a headscratcher that is usually assumed to be caused by a broken HVAC system. Again, in this case, you want a professional to take a look at your system to properly nail down the cause.

Uneven Temperatures

Another hard to diagnose sign that your AC thermostat might be malfunctioning is uneven temperatures throughout your home. If the thermostat cannot ascertain the correct temperature then the AC is left to random operation. This is not ideal and will lead to inefficient heating or cooling that can leave homeowners confused as to the cause. If all other parts of the AC are working correctly, and you’re still dealing with uneven temperatures then it might be time to consider the thermostat. This problem can be costly if parts of your AC are working against others due to uneven temperature readings.
