Bar Equipment Service Checklist

By Commercial Service Company · November 4, 2026

A bar runs on a handful of machines that almost never get a break: the back-bar cooler holding your garnish and bottled beer, the ice machine, the draft system pouring all night, and the glass washer keeping clean glassware in rotation. When one of them slips, it shows up fast, usually on your busiest night. A few minutes of regular checking catches most problems while they are still small.

Back-Bar Coolers and Reach-Ins

These units run constantly in a warm, high-traffic space, so they work harder than almost anything else behind the bar.

• Check that door gaskets seal tight all the way around and aren't cracked, torn, or pulling away from the door.
• Confirm the unit holds a safe, steady temperature and isn't cycling oddly or running long stretches without shutting off.
• Wipe down and vacuum the condenser coils if they're visible and accessible, since dust and bar lint buildup makes the unit work harder.
• Listen for unusual noise from the compressor or fan, and watch for water pooling underneath the unit.
• Keep the area around the coils and vents clear so air can move freely.

If you notice warm spots, frost buildup, a refrigerant smell, or anything electrical looking off, stop and call a licensed technician. Refrigerant and compressor work should never be handled in-house.

Ice Machines

Ice is one of those things nobody notices until it's not there, and bar ice machines take a beating from the volume alone.

• Check ice quality daily: cloudy, small, or oddly shaped cubes often point to a mineral buildup or water flow issue.
• Keep the bin and scoop clean, and store the scoop outside the ice rather than buried in it.
• Wipe down exterior surfaces and door gaskets, and make sure the bin drain isn't clogged.
• Watch production speed. A machine that used to fill the bin overnight and now struggles is telling you something.
• Have the machine professionally cleaned and sanitized on a regular schedule, not just when it looks dirty.

Internal cleaning, water line issues, and any refrigerant-related work belong to a licensed technician, not bar staff.

Draft Beer Systems

A draft system is only as good as its last cleaning. Off flavors, foam problems, and flat beer usually trace back to maintenance that got skipped.

• Check that beer is pouring at a proper temperature and with a clean, consistent head, not excess foam or flat pours.
• Inspect visible lines, faucets, and connections for leaks, mold, or buildup.
• Clean faucets regularly and keep drip trays emptied so they don't become a source of odor or buildup.
• Note any CO2 or gas pressure issues, but leave gas line work and regulator adjustments to a licensed technician.
• Schedule professional line cleaning on a routine basis. Lines that look fine on the outside can still have buildup inside that affects taste.

Glass Washers

A glass washer running slow or leaving spots puts dirty-looking glassware in front of customers, which is its own kind of bad first impression.

• Check that glasses come out clean, spot-free, and fully rinsed, with no detergent residue or lingering odor.
• Clean or replace spray arms, nozzles, and filters/screens according to the manufacturer's guidance, and keep them free of debris.
• Confirm the wash and rinse cycles are running at the proper temperature and duration.
• Check door seals and hinges for wear, and make sure drains aren't backing up.
• Leave electrical issues, heating element problems, and anything involving the water supply connection to a licensed technician.

Before a Busy Weekend: What's Worth a Professional Look

Daily checks catch a lot, but some things are easy to miss until a machine is under real pressure on a Friday or Saturday night. Before a weekend rush, it's worth having a technician look at:

• Any cooler or ice machine that has been running warm, cycling oddly, or making new noises.
• Draft systems due for a line cleaning or showing inconsistent pours.
• Glass washers that are slowing down, leaving spots, or not reaching proper wash temperature.
• Any equipment with electrical, gas, or refrigerant concerns. These should always go to a licensed technician rather than being worked on in-house.
