Water on the floor beside a desk is never a welcome sight, especially when the source is tied to commercial refrigeration. On July 10, 2026, our team at Arctic Air Inc. arrived at a Charleston, SC store after the customer contacted our office to report a walk-in freezer leaking into the office area.
The immediate concern was clear.
Water had reached the back of the store and collected near the desk. Our goal was to locate the source, make a secure repair, and confirm that no second leak was adding to the problem.
Following the Water Back to the Drain Line
We checked in onsite and began tracing the leak from the wet floor toward the walk-in freezer. The issue was not inside the office itself. Outside the freezer box, we found that the freezer drain line had disconnected from the PVC drain line shared by the walk-in units.
That loose connection gave drainage water a path onto the floor instead of carrying it through the intended piping. Once we identified the separation, the repair became focused and direct.
We secured the drain pipe connection with PVC cement.
This restored the connection between the freezer drain line and the shared PVC drainage system. Rather than replacing unrelated parts or expanding the repair beyond the confirmed source, we corrected the failed connection that was causing the water intrusion.
Cleaning the Area and Checking for More Leaks
Repairing the pipe was one part of the visit. We also cleaned the water from the floor so we could inspect the area under clearer conditions. Removing the standing water made it easier for us to watch for fresh moisture and determine if another source was present.
We found no additional areas leaking. By the time we departed, the floor was mostly dry, the drain connection was secured, and the repair was complete.
That final check mattered.
In a Charleston store, water near a desk or back-office work area can interfere with daily tasks and create an ongoing cleanup problem. Confirming that the visible leak had stopped gave the customer a clear result rather than an uncertain temporary fix.
A Straightforward Commercial Refrigeration Repair in Charleston
This project shows why a leaking walk-in freezer deserves a prompt inspection. The equipment may still be holding temperature while a disconnected drain line sends water somewhere it should not go. In this case, the customer noticed the leak in the office and contacted us before the situation spread further across the back of the store.
Our commercial refrigeration work includes diagnosing problems around walk-in freezers and the supporting components that keep them operating properly. For this Charleston service call, the solution came from following the evidence, securing the failed PVC connection, and checking the area after cleanup.
The customer was satisfied with the work performed, and we left with the job complete.

A thermostat set to 72 degrees should not leave a commercial space stuck at 78. That was the situation when a customer from Summerville, SC called our office for help with an AC system that would not cool properly. We arrived at 3:15 p.m. and began testing the controls, wiring, and equipment operation step by step.
The problem turned out to be more than a single failed part.
Two control boards were interfering with the system, and the zoned setup required careful troubleshooting to keep cooling available while we prepared the permanent repair.
Finding the First Failure in the Zoned System
We found proper voltage at the zone control board, but the board was not functioning correctly. This board coordinates thermostat calls and damper positions so each zone receives cooling when needed.
To get the system running, we bypassed the failed zone board. That temporary step revealed a second fault. The furnace control board was not sending voltage to the blower fan or the condenser, so the equipment still could not operate through its normal control sequence.
We then wired the fan and condenser directly to the thermostat. This temporary configuration restored interim cooling until both defective boards could be replaced.
The cooling temperature spread was limited during bypass operation.
All zones remained open, the bypass stayed open, and reduced air velocity affected performance. Still, the system was cooling instead of sitting idle, which mattered for a commercial property in Summerville during summer heat.
The National Weather Service maintains seasonal heat guidance for the South Carolina Lowcountry, where dependable cooling supports safe, usable indoor spaces.
Installing New Controls and Restoring Both Zones
We returned on July 15, 2026, checked in, and removed the defective zone control board. We mounted the replacement board directly to the furnace cabinet with self-tapping screws, then disconnected the thermostat wiring from the temporary bypass and completed the proper connections to the new board.
After restoring power, we found that the existing furnace board still would not send a signal to the blower relay. We replaced that board as well, completed the wiring, and powered the system again.
This time, the controls responded as designed.
Both zones cooled, both thermostats communicated properly, and the dampers operated with each zone. We also confirmed that the unit already had two transformers installed, an appropriate feature for this zoned configuration.
A Complete Commercial AC Repair in Summerville
The customer was extremely satisfied with the completed work. For us, the result came from staying methodical. Had we stopped after finding the first defective board, the repair would have remained incomplete. Testing after each step exposed the second failure and let us correct the full control problem.
At Arctic Air Inc., we provide commercial air conditioning service for businesses across Summerville and the Charleston area, including repairs, replacements, and preventive maintenance.
If your Summerville business has uneven temperatures, unresponsive zones, or an AC system that cannot reach its thermostat setting, schedule a diagnostic visit with our team.

Water was collecting above the ceiling, tiles were filling up, and drips were reaching multiple areas of a Moncks Corner commercial space. The call sounded like an air conditioner leak. Once we arrived, our inspection showed that the source was an airflow imbalance affecting the building.
Replacing wet tiles would have left the underlying condition untouched. We needed to learn why moisture was forming above the kitchen, dining room, and office areas, then correct the airflow conditions behind it.
Following the Water to an Air Pressure Problem
On July 13, 2026, we checked in at the Moncks Corner property and inspected the space above the ceiling. Water had been dripping from ductwork in both the kitchen and dining room.
The makeup-air unit was running, but the grates inside the exhaust hood were heavily clogged. In plain terms, the exhaust system was pulling more air from the building than the makeup-air system could deliver through those blocked grates. That created negative pressure.
Under negative pressure, humid air was drawn into the store through available gaps. When that moisture met the cold duct surfaces, the ducts began to sweat. Condensation collected above the ceiling, soaked tiles, and produced the dripping that prompted the service call.
We determined that the clogged grates needed to be cut out and replaced, then prepared a quote for the corrective work.
Restoring Airflow and Checking the Full System
We returned on July 18, removed the old hood grates, and discarded them. After vacuuming the accumulated dirt from the grate area, we installed new grates and restored power to the makeup-air unit.
Airflow into the hood improved noticeably, but we kept testing. The building remained slightly under negative pressure, so we inspected both air conditioning units and found air escaping around their horizontal supply discharge panels. Stripped screws were preventing the panels from sealing properly.
We replaced the screws and secured the panels.
A flow of cool air at the gap around the nearly closed roof hatch then indicated positive pressure inside the building. That change was expected to improve comfort and stop condensation above the ceiling.
We also confirmed that the makeup-air damper above the ceiling was fully open. During that inspection, we found two supply diffusers with loose fiberglass backing that had not been taped to the diffusers.
Cold air was leaking into the ceiling space at those points. We documented the condition as a remaining repair item, especially if the kitchen continued to feel uncomfortable.
A Satisfied Client and a Clear Next Step
Our customer was satisfied with the completed work. More importantly, we addressed the pressure condition driving the condensation instead of treating the damaged ceiling tiles as the whole problem.
For Moncks Corner business owners and property managers, wet ceiling tiles, dripping ductwork, or uneven kitchen comfort can signal a broader ventilation issue. Arctic Air Inc. provides commercial air conditioning repair for systems serving local businesses.
Call us to schedule an on-site evaluation in Moncks Corner. Acting early can help limit additional ceiling damage and give us a chance to identify airflow leaks before they disrupt staff, customers, or daily operations.
Water was leaking heavily from the walk-in cooler near the fans, but the visible leak was only the first sign of a larger drainage problem. When the customer contacted our office at Arctic Air Inc., we went to the North Charleston, SC, location to trace the source and restore normal drainage before the situation caused more disruption.
What we found connected the cooler leak, a failed heater, a burst freezer drain line, and significant ice buildup. It was a good example of how one clogged line can spread trouble across connected refrigeration equipment.
Finding the Cause Behind the Cooler Leak
We arrived on July 1 and inspected the Trenton walk-in cooler. The cooler drain line was clogged, so we cleared it with nitrogen and flushed it with hot water. That process confirmed the cooler could drain normally again.
Then we looked deeper.
The cooler and freezer drains emptied into the same copper pipe. While the shared line was blocked, water from the cooler backed into the freezer drain. The freezer drain heater had failed, allowing the backed-up water to freeze.
As the ice expanded, it burst the drain line inside the freezer and contributed to heavy ice on the shelving and floor.
Coordinating the Repair With Store Operations
The damaged freezer line and heater needed replacement, but the freezer also had to be empty and powered down so we could remove the ice and complete the repair. That made scheduling part of the plan.
We returned on July 10, but a freezer delivery prevented the work from moving forward. After speaking with Jeremy, we arranged a 6 a.m. return the next morning. That early visit gave us access to the equipment while limiting interference with the store’s daily activity.
Rebuilding and Protecting the Drain Line
On July 11, we disconnected and removed the damaged freezer drain line. We measured and soldered new hard copper pipe from the freezer outlet to the cooler drain connection.
We wrapped the new drain with heater cable, secured the cable, and connected power. Next, we added pipe insulation and secured it with foam tape and duct tape. Two brackets gave the drain added support.
During the work, we also found that the freezer suction line lacked insulation.
We insulated that line to help prevent future ice buildup. We sealed box penetrations with expanding foam, removed debris, dried the floor, restored freezer power, and confirmed the temperature was dropping. The client was satisfied with the completed repair.
Why Regular Refrigeration Service Matters
This project shows why routine commercial refrigeration service matters. A restricted drain or failed heater can begin as a manageable maintenance item, then lead to standing water, ice accumulation, damaged piping, and lost access to refrigerated storage.
Our commercial refrigeration service and maintenance covers coolers, freezers, tanks, and related equipment across the Charleston area. Regular inspections can help identify slow drainage, heater problems, missing insulation, and other warning signs before they grow into larger repairs.

A silent walk-in cooler can create a loud problem for a Charleston business. When this customer called our office, the unit was no longer cooling after a power outage and surge the day before. We arrived at 10:30 a.m. ready to trace the failure, protect the equipment, and find a reliable path back to steady cooling.
Commercial refrigeration repair is a core part of our work at Arctic Air Inc. We serve Charleston and the surrounding Lowcountry with cooler, freezer, tanks, ice machine, and HVACR service for local businesses.
Starting With the Electrical Damage
The customer had already noticed a burned wire coming from the compressor.
That visible damage gave us an important starting point, but we did not assume it was the only issue. We replaced the capacitor, then tested the compressor and its plug to confirm they were not shorted to ground.
That step mattered. We needed to rule out deeper electrical damage before asking the walk-in cooler to carry a full cooling load again.
Once the capacitor was replaced, the system still would not run normally.
It was stuck in a high-pressure lockout, a safety condition that stops operation when the controls detect excessive pressure. We temporarily bypassed the pressure switch for diagnostic purposes and confirmed that the switch was the problem.
Watching the Temperature Fall
After we removed the failed switch from the circuit, the unit began dropping temperature by 10 degrees every 10 minutes. That was a strong cooling rate and showed that the compressor and refrigeration system could pull the box temperature down once the faulty control was isolated.
We then went to the supply house to obtain the specific pressure switch required for the unit. After returning to the Charleston site, we installed the correct replacement rather than leaving a temporary bypass in place.
Planning the Follow-Through
Pressure switch removal and replacement can affect the refrigerant charge, so we recommended watching the cooler through the weekend to confirm that it continued reaching its target temperature. If the system needed more refrigerant, the customer already had a factory-sealed jug of R-404A available for the next service step.
That recommendation gave the customer a practical way to track performance without claiming the system needed refrigerant before the operating data proved it. The cooler was pulling down at a good rate when we completed the repair, and the customer was satisfied with the work provided.
For local restaurants, retailers, and facility managers, a walk-in cooler failure can quickly disrupt normal operations. Our commercial refrigeration team handles repairs, inspections, and preventive service across the Charleston area, with emergency help available when cooling equipment cannot wait.

“The freezer has been acting funky.”
That concern brought our Arctic Air Inc. team to a Summerville, SC, commercial property for a closer look at the refrigeration equipment. The customer had called our office and asked us to inspect the fridge, freezer, and sandwich station. Everything was still running, but the freezer’s recent behavior raised a fair question: did the equipment need service before a larger issue developed?
We arrived at 2:00 p.m. and began with an inspection of the three-door freezer and the other requested equipment. Our goal was straightforward.
We needed to verify current performance, identify maintenance needs, and give the customer a clear recommendation based on what we found.
A Concern Worth Checking Before It Became Downtime
Commercial refrigeration can appear operational while dirt and drainage problems build out of sight. During our inspection, we found that the condenser coils needed maintenance. The project photos showed visible dust and debris spread across the coil area, along with buildup around nearby components.
At the time of inspection, both systems were meeting their operating demands. That mattered, but it did not erase the maintenance need in front of us. We explained the recommended cleaning and provided a price for the work.
Once the customer approved it, we moved ahead during the same visit.
Cleaning the Coils and Clearing the Lines
We maintained both systems by cleaning the condenser coils and removing the accumulated debris. This addressed the condition documented during our inspection and left the coil areas visibly cleaner.
Next, we vacuumed the drain lines to clear the existing clogs. Rather than treating the freezer concern as a single symptom, we worked through the maintenance items found during the visit. That approach gave the customer a practical answer and helped leave the equipment in verified operating condition.
There was no dramatic shutdown scene here.
Frankly, that was good news.
The customer called while the equipment was still working, and we had the opportunity to inspect, recommend, clean, clear, and test without a reported loss of operation.
Confirmed Performance for a Summerville Business
After completing the coil cleaning and drain-line work, we checked system operation.
Both systems were performing to manufacturer specifications at that time. The customer was satisfied with the work performed and received a clear result from the original service request.
For local business owners and property managers, this project shows the value of acting when equipment starts behaving differently, even when it has not stopped running. Our commercial refrigeration work covers service, repair, and preventive maintenance for Summerville-area businesses.

A kitchen team in Mt. Pleasant, SC, was convinced their space was running too hot. They knew how the room felt during a workday, and they wanted a clear answer from a company they already trusted.
As a current customer, they called us to investigate. Our job was not to arrive with a repair already in mind. Our job was to check the conditions, document what we found, and give the customer an honest explanation.
That approach led to a result many service calls do not: the cooling was working correctly, and no unnecessary fix was recommended.
A Real Comfort Concern Deserved a Real Check
Working kitchens can feel warm for several reasons. Cooking equipment, constant movement, open doors, and the number of people in the room can all affect how comfortable the space feels. For a Mt. Pleasant business, that discomfort can quickly raise concerns over cooling performance.
We took the complaint seriously.
A room can feel warmer than expected even when the measured temperature says something different, so assumptions would not help anyone. We needed clear information.
We checked the kitchen temperature and captured photos of the readings. Those images became the receipts. The numbers showed that the space was cool, confirming that the cooling was performing as expected at the time of our visit.
We Explained the Finding Without Selling a Fix
This was the most important part of the visit. We did not turn a comfort complaint into a repair recommendation that the property did not need.
Instead, we showed the customer the documented temperature readings and explained the difference between how the kitchen felt and what the thermometer recorded. The kitchen staff may still have felt warm while working, but the evidence showed that the cooling itself was doing its job.
That honest answer gave the customer something more useful than a needless service bill. It gave them clarity.
Through our commercial air conditioning service, we focus on careful evaluation, clear communication, and recommendations that serve the customer’s best interest. Sometimes that means completing a repair. Other times, as this Mt. Pleasant visit showed, it means confirming that the equipment is operating correctly.
Good Service Can Mean Leaving a Working System Alone
The customer was satisfied with the outcome. They had raised a valid concern, we investigated it, and the recorded temperatures provided a straightforward answer.
For us, that is dependable service. We never want a customer to feel dismissed when a room seems uncomfortable. We also will not recommend work without evidence that it is needed. Both parts matter.

A walk-in cooler that stops cooling can put an entire business under pressure. Products may be at risk, daily routines can stall, and every passing hour matters. When one of our current customers in Summerville, SC, asked us to check a non-cooling unit, we arrived ready to trace the failure rather than swap parts at random.
The cooler had stopped operating following a power outage the day before. Once we opened the equipment and began testing, we found a burned wire and a failed capacitor. The outage was the likely source of that electrical damage. Those findings gave us a clear starting point, but they did not tell the whole story.
Following the Fault From One Component to the Next
We replaced the bad capacitor and tested the walk-in cooler again. It still would not run.
That second test mattered. It showed us another fault remained inside the system. We continued the diagnosis and found a failed safety switch that was keeping the cooler shut down. Safety switches are designed to stop equipment when operating conditions fall outside safe limits. In this case, the switch itself had failed.
We replaced the faulty switch and started the cooler. This time, the system came back to life and began pulling the temperature down.
Measuring the Recovery, Not Guessing at It
Getting the unit to start was only one part of the repair. We also watched how quickly the temperature responded.
The cooler dropped roughly 10°F every 10 minutes during our post-repair check. That rate was a positive sign that the equipment was actively cooling and moving in the right direction. The customer was satisfied with the result, and the cooler was operating normally when our work was complete.
Because replacing the safety switch required opening the sealed refrigerant system, we explained that the refrigerant charge could need minor fine-tuning. We recommended monitoring the cooler through the weekend to confirm it reached the proper temperature and held it steadily.
That follow-through matters for Summerville businesses that depend on cold storage throughout daily operations. A system can restart successfully yet still benefit from close temperature checks after a refrigerant-side repair.
A Practical Repair for a Current Customer
This service call shows why commercial refrigeration diagnosis should be methodical. The failed capacitor was real, but it was not the only issue. By testing after each repair step, we uncovered the faulty safety switch instead of leaving the customer with a cooler that still could not run.

Early diagnosis can help protect stored products, limit downtime, and uncover connected electrical or control problems before they grow.
A commercial kitchen creates serious heat long before the lunch rush peaks. At this Charleston, SC property, that heat was pushing into the lobby while the cooling system struggled to keep pace. The client reached out to Arctic Air Inc., and we arrived ready to trace the failure instead of replacing parts on a hunch.
The project photo added useful context.
Dark residue was visible across the patterned ceiling grilles, showing that the indoor air path needed attention in this hard-working kitchen setting. We later confirmed that the store’s filter needed replacement as well.
That matters in Charleston, where normal July daytime highs in North Charleston sit near 91 degrees Fahrenheit, adding outdoor heat to the load already created by cooking equipment.
Following the Electrical Clues
We began with a full diagnostic on the kitchen condenser, the outdoor section that releases heat from the cooling system. The condenser fan motor had seized, which meant it could no longer move air across the coil.
We also found that the compressor was not starting even when the electrical contactor engaged. Rather than assume the compressor itself had failed, we checked voltage and electrical resistance, commonly measured in ohms.
Those readings led us to the compressor plug and terminals, which were caked with gunk.
After we cleaned the terminals, the compressor started running again. That step mattered. Careful testing allowed us to restore the electrical connection before moving toward a far larger repair.
We then picked up a new condenser fan motor and installed it. With the new motor in place and the compressor connection cleaned, the system returned to operation and performed within manufacturer specifications.
Cooling Restored, Airflow Still on Our Radar
The client’s positive update was clear: everything was running fine. We still gave an honest reading of the full system. The temperature split, which compares return-air temperature with cooled supply air, was not especially strong. The lobby also continued to struggle against the heat produced by the kitchen.
The dirty interior filter remained an important next maintenance item.
A clogged filter can limit airflow, so changing it is a practical step toward helping the system move cooled air through the store more effectively. The visible buildup around the ceiling grilles reinforced that need.
Why Thorough Diagnostics Matter in Commercial Kitchens
This repair showed why we look beyond the first failed component.
A seized fan motor was a clear problem, yet the compressor connection created a second issue that could have pointed toward a much more expensive conclusion. We tested, cleaned, verified, replaced the failed motor, and documented the remaining airflow concern.
Our team provides commercial air conditioning repair and preventive maintenance across the greater Charleston area, supporting restaurants and other local businesses with systems that work under demanding conditions.

A frozen air conditioning system can look like a refrigerant problem at first glance. At this Summerville, SC property, the real cause sat inside the ductwork: a failed zone damper that restricted airflow until the system froze.
The client called our Arctic Air Inc. office for help.
Once we traced the trouble to the defective damper, we had a clear path forward. The customer approved the replacement of the 14-inch zone damper assembly, and we began the repair with one goal: restore proper airflow, then verify the system could cool and drain normally again.
Why One Failed Damper Stopped the System
A zone damper opens and closes inside ductwork to direct conditioned air to specific areas. When it fails in the wrong position, airflow can drop sharply. In this case, that lack of airflow caused the system to freeze up.
That matters in Summerville, where warm Lowcountry weather makes reliable cooling especially important. We provide air conditioning repair, ventilation, and maintenance services across Summerville and the greater Charleston area.
Fitting and Sealing the New Damper
We removed the defective zone damper and installed the new 14-inch assembly. Zip screws secured the new component in place. We then taped the existing duct to the damper assembly so the connection stayed tight.
The insulation had to return over the repair, too.
We pulled the existing insulation back over the assembly, secured it with tape, and sealed the full area with mastic. Mastic is a thick HVAC sealant used to close small gaps around duct connections. We also returned the duct support straps to their proper positions.
The mechanical installation was only part of the work.
We made the wiring connections to the new damper motor, restored power, and checked its operation. Each step mattered because a loose connection, poor seal, or unsupported duct section could interfere with performance later.
Confirming Normal Cooling Before We Left
We let the unit run for 15 minutes after the repair. The system pressures measured 378 psi and 143 psi. Superheat, a reading used to evaluate refrigerant performance, was normal at 12 degrees.
Most importantly, the unit was cooling and draining normally. Those final checks confirmed that the new damper was operating and airflow had returned. We did not stop after installing the part. We stayed long enough to see the system run and to confirm the readings were where they needed to be.
The customer was very pleased with the completed work. For us, that reaction matched the result we wanted: a careful repair, a properly sealed duct connection, and a cooling system back in normal operation.
