Refrigeration Maintenance Pays: A Client Lesson

It never pays to be penny-wise & dollar-foolish when it comes to maintenance of commercial refrigeration. Hopefully you can learn from this customer’s expensive lesson!

We received a call on a Saturday in August for emergency service. As Murphy’s Law would have it, their 2-door cooler broke down on the weekend, when repairs come at a premium.

Let’s backtrack for a minute. We quoted this customer a full comprehensive maintenance plan back in November of 2011. This maintenance, if performed, likely would have prevented the cooler in question from breaking down. The maintenance would definitely save the customer on energy usage & extend the life of the equipment. Unfortunately, as is all too often the case, the customer did not schedule or approve our refrigeration maintenance proposal. Have a look at our quote below for the maintenance work:

Fast forward to the emergency service call. Their 2 door cooler was running at 70 degrees, which we diagnosed as a bad condenser fan motor. Most likely, the fan motor overheated due to the condenser coil being plugged with grease. The compressor was extremely overheated & tripping off on overload. We had to cool the compressor with ice, degrease the coil several times & replace the condenser fan motor. All this was done at our Saturday rate, which is 1.5 times our regular rates. Now take a look at the invoice for emergency Saturday service:

(Note: Our current regular business hour rates are as follows $65 service charge $115.50 per hour plus parts)

 

Here is how it breaks down:

  1. The emergency service on the one cooler was almost $200 more than the entire maintenance proposal for 12 Refrigeration Units.
  2. The other 11 Refrigeration Units are still overdue for maintenance.
  3. The compressor on cooler serviced has been severely strained & may fail soon.

This scenario is something we see all the time: We try to preach the benefits of  routine maintenance, but it is all too often ignored. For the handful of clients who routinely maintain their refrigeration equipment, the units are operating much more efficiently and have far fewer breakdowns than units that are not serviced regularly. We recommend a thorough maintenance inspection be done a minimum of twice per year.

DIY Commercial Refrigeration Maintenance Inspection

We’re here to help you with all things commercial refrigeration. We’d like to help you keep your machines running smoothly between maintenance calls. So, with some information and timely tips our aim is to assist business owners in better understanding when it’s time to make that call to schedule a maintenance appointment for their commercial coolers and freezers in Chicago. We’re also sharing some handy pointers on preventive maintenance that the end user can perform on their own.

First TIP, and essential, to a well running cooler or freezer:

Routine maintenance should be performed at least twice per year.

A thorough plan performed by a service company should include the following:

  • Pressure Cleaning Condenser Coils (degrease if necessary)
  • Pressure Clean Drain Lines
  • Monitor Temperature & Cycling
  • Check Refrigerant Level
  • Check Condenser and Evaporator Fan Motors & Blades
  • Check Electrical Connections: Wiring & Compressor
  • Check Unit Thermometer: Door Gaskets & Insulation
  • Check Door Hinges & Closers
  • Ice Machines should be taken apart & cleaned.
  • An acid descale solution should then be run through the water circuit.

This is what a dirty ice machine can look like:

If you own commercial refrigeration YOU should be aware of when the last maintenance service was performed.

If  you had maintenance service preformed over six months ago then you might be surprised to learn that it’s now OVERDUE. In between service calls you can help keep your machines running as efficiently as possible by cleaning out the dust and dirt. Most self contained coolers and freezers have a cover at the top or bottom. This cover can be removed by taking out two screws on each side. Refrigeration owners can remove this cover to inspect the condition of the condenser coil once a month.

This condenser so dirty it can cause compressor to fail:

Here is the same condenser with half,  and then all, of the dirt removed with a brush. BIG difference, right? This is something the end user can do in between full maintenance programs. Although, this does not remove all the dirt it will help you keep your unit running more efficiently between service calls. A service company will still need to come and blow out the coils with a pressure clean a few times a year.

If the refrigeration unit is a remote rack type like one pictured below, remove a side cover and look up from bottom to inspect condition of condenser coil.

 Here are the main things a customer can do between maintenance visits:

  • Check air-cooled condenser coils on coolers, freezers, and ice machines. These are the fan coils on the exterior of the unit. Brush off the dirt without damaging the aluminum fins.
  • Check ice machines. Remove cover and inspect interior for signs of mold or slime build-up. If any build-up is found call a service company.
  • Check door gaskets on coolers and freezers. Inspect for rips or tears.
  • Check automatic door closers and hinges on equipment.

Keep in mind the following:

Equipment may still maintain temperature EVEN when in need of maintenance. It will also use significantly more electricity and be prone to major component failure.

In the case of refrigeration equipment an ounce of prevention is definitely worth a  pound of cure!

Summer Sizzle Elicits One Word: Maintenance!

 

After this past week’s heat brief, but brutal, heat wave we just cannot stress enough the importance of maintaining your commercial refrigeration equipment. While we love the business, we hate to see you in a bind!

Even one of our friends learned the hard way at home in Lake County. “Who needs to check the air conditioning?”  Our friend has since changed her tune when the a/c unit refused to turn on as the temperature inside the house was soaring to 89 degrees!  The guilty will remain nameless to shelter her from further shame at the lack of preventative maintenance.

She survived, but you don’t want the same thing to happen to your commerical refrigeration equipment!

You NEED your ice machine!

You NEED cooling for your food and beverage service.
