Cold Storage

When a commercial refrigerator breaks down, that can mean a huge loss in profits for a business owner. Components inside commercial coolers and freezers can malfunction leading to warming or spoiling of food, medicine, and more. We can fix or replace your unit, but timing is key! Be on the lookout for signs that your commercial refrigerator is in need of repair. Signs include: excessive frost or condensation, overheating motor, items expiring before expiration date, high electricity bills, or the unit is showing a temperature other than zero degrees.

Don’t let your faulty fridge cost you!
