Commercial Chiller Service & Repair in New Bern, NC

GP Heating & Cooling is a family-owned and locally-owned company based in New Bern, NC. Our commercial team services and repairs chillers that cool your building. We maintain and repair the chillers already in place at your property, and we do not install or replace them. Each visit begins with the controls and safety protections, then moves through the refrigerant circuit, compressor and chilled water flow, ending with plain-language findings. Backed by 22 years of experience, we recommend only the work your equipment needs.

Our Chiller Approach

Six Commitments Behind Every Chiller Visit

A chiller carries cooling for an entire building through its hottest weeks, so the way we approach the work matters as much as the repair itself. These commitments guide every chiller call we take.

  • Family ownership that stays with your account

    Our company is family-owned, so the people who schedule your chiller visit are the people who answer for the findings. A chiller can serve a building for many years, and that relationship depends on a company that stands behind its diagnosis. Our About Us page describes our background in more detail.

  • Controls and protections verified before tuning

    We check the safety protections and controller responses before adjusting anything for comfort. A chiller that delivers cooling but fails a protection test is not ready to return to service, and we say so plainly.

  • Measured readings behind every recommendation

    Each recommendation is tied to temperatures, pressures, amperage and flow measured during the visit. Facilities staff can see the numbers behind each finding, which makes decisions with owners and outside engineers easier to defend.

  • Scheduled visits that fit the building’s cooling load

    We plan visits around the operating hours and seasons of your property, so testing does not interrupt the peak demand your occupants depend on. We agree on access and timing before any work starts.

  • Honest guidance when repair stops making sense

    When a chiller reaches the limit of economical repair, we explain the readings that show it and describe your options plainly. Our commercial team does not install or replace chillers, so our advice centers on what your existing equipment can reliably deliver.

  • Local sponsorships that reflect the same values

    We sponsor a local Christian school and a Sunday School recreation league. The businesses we serve in New Bern and nearby communities are our neighbors, and they receive the same candid diagnosis we give family homes.

Tell Us About Your Chiller

Describe What Your Chiller Is Doing

Send us the symptoms, the age of the chiller if you know it, and the areas of the building that feel warmer than their setpoint, using our contact page. Our technicians come to your property to test the equipment where it operates, so nothing needs to be removed or shipped away. If the readings point to a larger concern, we explain it in plain terms before anything is approved. Businesses that also run other commercial equipment can review our rooftop unit repair and maintenance page, our boiler service and repair page and our commercial HVAC overview.

Early Chiller Signals

Chiller Symptoms Worth Investigating

  • Supply Water That Drifts Above Its Target

    Supply temperature that climbs above the setpoint, even at full demand, suggests the chiller is losing capacity somewhere in the system. The cause may be low refrigerant, fouled heat exchanger surfaces, weak flow or a control problem. We measure supply and return temperatures, compare them with the design targets and identify which factor is limiting cooling before recommending any work.

  • Repeated Safety Trips or Lockouts

    A chiller that trips on high pressure, low flow or low water temperature is reporting a condition that needs investigation. Resetting it again and again can mask the fault and place extra stress on the compressor. We review the fault history, test the device that responded and confirm that the protection works as intended.

  • Unusual Compressor or Motor Noise

    Knocking, grinding, whining or new vibration from the compressor or motor often signals wear, misalignment or a failing mount. Noise that grows over several weeks deserves attention before it reaches a larger component. We listen for the pattern, measure amperage draw and inspect the mounts and internal components we can reach.

  • Oil Staining or Frost Near Connections

    Oil residue around fittings, valves or coil connections can indicate a leak, while unexpected frost on lines points to flow or charge problems. Both conditions reduce capacity over time. We inspect each connection, test the circuit where access allows and record each location we confirm.

  • Uneven Cooling Across the Building

    When one wing runs warm while others stay comfortable, flow restrictions, air trapped in the loops, failed valves or balancing problems may be sending chilled water the wrong way. Occupants often notice this first at the far end of a loop. We measure temperatures on each accessible loop and record where cooling falls short.

  • Rising Energy Use Without a Change in Operation

    A chiller that draws more power to produce the same cooling may be losing efficiency through fouled surfaces, low charge, pump wear or a control schedule that no longer matches the building. Tracking this pattern helps identify a developing problem early. We compare the readings with the design and point to the component that explains the change.

How We Service Your Chiller

How a Chiller Visit Unfolds From Start to Finish

Each visit follows a fixed order, beginning with the operating record and ending with written findings. Controls and safety protections come before performance, and facilities staff receive a record of every test we perform.

Step 1 of 5

Review the Operating Record

We begin with what your staff has observed before any panels come off.

  • Record the chiller make, model and approximate age from the nameplate.
  • Ask when the problem began and whether it follows a time of day, a load pattern or a season.
  • Collect past service notes, repair records and any recent control or building changes.
  • Confirm the supply temperature setpoint, the reset logic and the person who adjusts them.
  • Agree on the areas that will lose cooling during testing and the timing of any shutdown.

Common Chiller Repairs

Chiller Components We Diagnose and Repair

  • Compressors and Motor Starters

    Worn compressor components and failing motor starters can cause noise, nuisance trips or lost capacity. We measure amperage draw, test starter operation and recommend repairs that restore dependable running.

  • Condenser and Evaporator Surfaces

    Fouled or scaled heat exchanger surfaces reduce heat transfer and raise operating temperatures. We inspect both surfaces, clean them where appropriate and note any damage that needs attention.

  • Chilled Water Pumps and Flow Devices

    Weak pumps, clogged strainers and flow switches that drift all disrupt cooling delivery. We test pump operation and flow devices, then repair or replace components that no longer hold their rated performance.

  • Refrigerant Leak Detection and Repair

    Leaks lower cooling capacity and often hide behind fittings and coil connections. We test the circuit, locate the source where access allows and repair the affected component before confirming the system holds.

  • Expansion Devices and Pressure Controls

    An expansion device or pressure control that responds poorly can starve the evaporator or cause repeated trips. We check control response, verify settings against the design and replace parts that no longer track correctly.

  • Chiller Controllers and Sensors

    Miscalibrated sensors and faulty control wiring send the wrong signals to the chiller. We verify each sensor reading, inspect the wiring and correct the sequence that governs staging and capacity.

  • Oil Condition and Lubrication Checks

    Low or degraded oil shortens compressor life and can trigger protective shutdowns. We check oil level and condition, inspect return paths and recommend the service that keeps lubrication within its range.

Talk with Our Team

Your New Bern Commercial Chiller Contractor

A chiller that runs well keeps a building comfortable through the hottest weeks of the year, while a unit that quietly loses capacity can turn a small fault into a costly disruption. Tell us what the system is doing, where cooling falls short and what your staff has noticed, and our team will review the equipment on site. A repair decision should rest on measured data. We explain the readings behind each recommendation, separate required items from improvements that can wait, and offer only the work your building needs.

Service Finance is available for qualifying projects, so a larger repair can be planned around monthly payments rather than absorbed as a single expense. Our financing page explains how the program fits a commercial budget. Between repairs, planned care keeps the controls, compressor and flow components on a predictable schedule, and our commercial maintenance plan is built for that purpose. Ask about the plan when you call, and we will explain how it applies to your property.

Whether your property sits in New Bern or in one of the five communities we serve, our team welcomes questions about chiller testing, repair decisions and planned care. Our crews work with building managers, owners and maintenance staff alike, so the findings reach the people who must approve the work. You can also review our full range of services to see how chiller service fits alongside the heating, cooling and gas line work we handle. When you are ready, reach out and we will explain what we find before recommending anything.
