Commercial Refrigeration

Helping Businesses in Delafield Keep Their Products and Beverages Cool

Do you rely on commercial refrigeration to keep your business in Delafield running? Have you noticed your chiller or walk-in cooler isn’t keeping things cool enough? Though it might make this month’s budget look better, putting off repairs on vital equipment—like things you use to cool your inventory—can lead to huge costs down the road. Spoiled products could make someone sick or lead to a 1-star review or thousands in discarded products. Unfortunately, commercial refrigeration service is something few companies in Delafield do well. When it comes to repairing and maintaining equipment worth more than five digits, it’s important to have a local HVACR company on speed dial./p>

Common Commercial Refrigeration Problems in Delafield

Many of the problems we see on a daily basis are the direct result of skipping annual tune-ups or refusing to invest in preventive measures. Below is a small list of the most common issues our refrigeration technicians encounter:

  • Dirty Units: Whether it’s blood from defrosted meat or just dust, grime build-up makes your refrigeration equipment work harder to do its job. Clean up spills immediately and avoid harsh chemicals during cleaning.
  • Skipped Maintenance: In our 36 years serving the Delafield area, we’ve learned how vital regular maintenance is to keeping your refrigerated equipment in prime operating condition. Quarterly visits from a commercial refrigeration expert in the Delafield area will extend the life of your equipment and improve your bottom line. Give (262) 646-3880 a call to join our business maintenance club.
  • Damaged Fan Blades or Coils: We recommend having an HVAC-R company out four times a year to clean and grease your fans. If an issue is noticed, the defective part needs to be replaced immediately. Skipping this regular maintenance can lead to total fan failure.
  • Missing Seals and Bent Hinges: Whether it’s due to moving products or slamming doors, hinges and seals take a beating in commercial environments. Door hinges should be lubricated regularly and seals checked on a quarterly basis. To ensure the system closes, regularly clean any residues that build up. This ensures a better-contained system and limits system strain.
  • A Lack of Temperature Tracking: The thermostats on refrigerated equipment aren’t there for show. They’re meant to be regularly examined. We advise most businesses to invest in an automated tracking system to avoid issues with human error or negligence. If you notice a long-term temperature change, there may be something wrong with the unit.
  • Clogged Drains: Most refrigeration units have a drain at their base. When this becomes clogged, the floor can flood, leading to frost build up on the interior walls. This forces your condensing unit to work harder. If left unattended, this can shorten equipment life and elevate your utility bills.
Looking for a way to avoid these problems? Reach out to us at (262) 646-3880 to get information on our commercial HVACR maintenance program in Delafield. Doing so will give you and your stakeholders peace of mind.
