Bohn is a long-standing brand of walk-in refrigeration equipment, including condensing units and unit coolers. Common repairs are dirty coils, fan motors, capacitors, contactors, defrost parts, controls and leaks. Find the Bohn nameplate, note the refrigerant and call with what the walk-in is doing.
The Bohn name appears on many condensing units and unit coolers serving walk-ins in restaurants, grocery stores and institutions around Hattiesburg, including some that have been running for many years.
About Bohn equipment
Bohn refrigeration equipment is part of the Heatcraft family of brands. It covers condensing units for outdoor or rooftop installation and unit coolers mounted inside the walk-in, for both cooler and freezer temperatures. Older Bohn units may still run on refrigerants that are now expensive or phased down, which affects repair choices.

Older units and refrigerant
If your Bohn unit is older, check the nameplate for the refrigerant. Systems on R-22 or R-404A can usually still be repaired, but refrigerant cost and availability may change the repair or replace decision. See R-22 phase-out and R-404A.
Before you call
- Photograph the nameplate on the condensing unit or unit cooler.
- Note the refrigerant listed on the nameplate.
- Note whether it is a cooler or freezer system and the defrost type if known.
- Describe what it is doing: temperature, fans, ice, noise or tripping.
- Note the box brand if there is a label on the door frame.
Do not open electrical panels, touch capacitors or loosen refrigerant fittings. The troubleshooting guide lists safe checks, and the brands guide shows where to find every nameplate.
What we look at on a Bohn system
Bohn units in the area range from recent installs to systems that have run for many years. On older units we check the refrigerant type first, because it shapes every repair decision, and look for oil stains at joints that signal slow leaks. We test the crankcase heater, pressure controls and fan motors, and on unit coolers the defrost heaters and termination switch. We will tell you plainly whether a repair or a new condensing unit makes more sense.
Repair, upgrade or replace
A well-kept Bohn unit can run for many years. When major parts fail on an old system, compare the repair cost with a new condensing unit before deciding. See the repair or replace guide and upgrades and retrofits.
