Foam Is Product Going Down the Drain
Beer Cooler Repair
in Longview, TX
A draft system that pours foam is usually described as a beer problem and is almost always a temperature problem. Beer that warms even a few degrees between the keg and the faucet releases dissolved carbon dioxide, and what comes out of the tap is foam. Every inch of that foam is product you bought and cannot sell.

What We Service
Beer Cooler & Draft Cooling Services
The refrigeration side of a draft system — the part that decides whether what you pour is beer or foam.
Temperature Problems
Beer wants a narrow and consistent range. A cooler that drifts, or one where temperature varies across the box, causes foaming at the tap.
- Drift & Inconsistency
- Uneven Box Temperature
- Airflow Problems
- Thermostat & Controls
Frozen or Over-Cold Beer
The opposite problem and just as costly. Beer near freezing pours flat and cloudy, and a frozen keg line is a service stoppage.
- Over-Cooling
- Frozen Lines
- Control Faults
- Airflow Distribution
Draft Line Cooling
Glycol chillers and forced-air cooled trunk lines. Beer that is correctly chilled in the box and warms on the way to the tap still pours foam.

Doors, Gaskets & Seals
Behind a bar, cooler doors get opened constantly all night. Gaskets and hinges wear far faster here than on kitchen equipment.

Preventive Maintenance

Why It Foams
Temperature and Draft Beer
Foaming is one of the most common complaints in a bar and one of the most consistently misdiagnosed.
Why warm beer foams
▾
Beer holds dissolved carbon dioxide, and how much it can hold depends on temperature and pressure. Warm it up and the beer can no longer hold that gas in solution, so it comes out — which is exactly what foam is. Even a few degrees of warming between the keg and the faucet is enough to turn a clean pour into a glass of head. This is why draft problems are so often a refrigeration issue rather than a dispensing one.

Warm spots along the line
▾
It is not enough for the keg cooler to be at the right temperature — the beer has to stay there the whole way to the tap. On any run of more than a few feet the line needs active cooling, either glycol or forced air. A failed chiller, a gap in the insulation, or a section of line that has come away from the cooling bundle creates a warm spot, and beer foams at that point regardless of how cold the box is.
Commercial HVAC →
Too cold is also a problem
▾
Over-cooling is less discussed and just as costly. Beer approaching freezing pours cloudy and flat, loses carbonation character, and in a bad case the line or the keg itself freezes and service stops entirely. A cooler that has drifted cold is as much a fault as one that has drifted warm, and it is often a control or airflow distribution problem rather than a thermostat setting.

When it genuinely is not the cooling
▾
We would rather tell you that than sell you a repair. Foaming can also come from incorrect gas pressure, the wrong gas blend for the line run, dirty lines, worn faucet washers, or a keg that was jostled recently. What we can do is establish whether temperature is in range from keg to tap — and if it is, tell you plainly that the problem is on the dispensing side rather than ours.
Commercial Services →Foaming — Where to Look
We confirm the temperature side; some causes are dispensing.
| Cause | Refrigeration? | Symptom |
|---|---|---|
| Beer cooler too warm | Yes | Foaming worsens through the night |
| Warm spot in the trunk line | Yes | First pour foams, then settles |
| Glycol chiller failure | Yes | All taps foaming |
| Cooler too cold | Yes | Flat, cloudy pour or frozen line |
| Gas pressure or blend | No — dispensing | Consistent foaming at correct temperature |
| Dirty lines or worn washers | No — dispensing | Off flavours, uneven pour |

How It Works
How a Beer Cooler Call Works
Measure from the keg to the tap, then fix what is actually out of range.
1
Symptom and Timing
When it foams matters — all night, only at open, or worse as service goes on. Each points somewhere different.
2
Measure the Whole Run
Box temperature, line temperature and temperature at the faucet. Foaming is usually where those three disagree.
3
Repair the Cooling Side
Flat rate, agreed first, whether it is the cooler, the chiller or a warm section of line.
4
Honest Handover
If temperature is correct throughout and it still foams, we will tell you the problem is on the dispensing side.
Warning Signs
Signs Your Beer Cooling Needs Attention
In a bar these show up as wasted product long before anyone calls it a refrigeration fault.
Foaming that gets worse through the night
The classic signature of a cooler struggling as ambient temperature and door openings accumulate.
The first pour foams, then settles
Usually a warm spot in the line rather than the cooler. The warm beer clears and the properly chilled beer follows.
Cloudy or flat beer
Often over-cooling rather than under. Beer close to freezing loses condition and pours poorly.
Ice anywhere in the box or on the lines
Either a defrost problem or over-cooling. Frozen lines stop service entirely.
The cooler running constantly
Struggling to hold range. Usually a dirty condenser, a worn gasket or a refrigerant issue.
Door not sealing behind the bar
Bar cooler doors cycle constantly all night. Gaskets wear out here faster than anywhere else in the building.
What We Find Most Often
Dirty condenser coils
Behind a bar they collect dust and airborne residue quickly, and the unit stops being able to reject heat.
Worn door gaskets
Very high door cycle counts mean bar cooler gaskets are a consumable rather than a permanent fitting.
Glycol chiller faults
Beer correctly chilled in the box, warming on the way to the tap. Every tap foams and nobody suspects the cooler.
Control and thermostat drift
A box slowly running warmer or colder than its setting, which nobody notices until the pours change.

Common Questions
Beer Cooler & Draft Questions
What bars and restaurants ask about draft cooling.
Why is my draft beer foaming?
▾
Most often temperature. Beer holds carbon dioxide in solution, and warming it even a few degrees releases that gas — which is what foam is. The warming can be in the cooler itself or at a warm spot along the line to the tap. Other causes exist on the dispensing side, such as gas pressure or dirty lines, but temperature is where we would look first and where the answer usually is.
What temperature should a beer cooler be?
▾
Generally around 36 to 38 degrees, though the important part is consistency and that the temperature is maintained the whole way to the tap rather than just in the box. A cooler holding perfectly at 38 with a warm section of trunk line will still pour foam, because the beer warms on its way. That is why we measure at the keg, along the line and at the faucet.
Can beer be too cold?
▾
Yes, and it is a genuine and under-recognised problem. Beer approaching freezing pours cloudy and flat and loses its carbonation character, and in the worst case the line or the keg freezes and service stops. A cooler that has drifted cold is as much a fault as one that has drifted warm, and it is usually a control or airflow distribution issue rather than someone setting it wrong.
Do you service the draft lines as well as the cooler?
▾
We handle the refrigeration side — the cooler, the glycol chiller and the cooling of the trunk line. Line cleaning and the dispensing components such as gas, regulators and faucets are typically handled by a draft service specialist or your distributor. What we will do is establish definitively whether temperature is in range throughout, so you know which conversation to have.
How quickly can you respond?
▾
Around the clock, and we are conscious that bar equipment has a habit of failing on a Friday evening. Our line is answered by a person at any hour and beer cooler failures are dispatched with the same urgency as any other refrigeration call, because product at risk is product at risk.
How often should beer coolers be serviced?
▾
At least twice a year, and ideally scheduled ahead of your busy season rather than during it. Behind a bar the two items that matter most are condenser coil cleaning and door gaskets, because the coils collect residue quickly and the doors cycle far more than kitchen equipment. Both are inexpensive on a schedule and expensive as an emergency.
