Pierre Refrigeration Services installs and services commercial HVAC for businesses in Peachtree Corners, GA and nearby Gwinnett County communities. Rooftop units and split systems serve offices, stores, schools and other workplaces; restaurants can also ask about make-up air and kitchen exhaust. Note where comfort or airflow changes so the technician can evaluate the system rather than guess at a part.

What is the equipment telling you?

Tell us where comfort or airflow has changed: the sales floor, classrooms, offices or kitchen. The location and pattern help distinguish a system fault from a ventilation or distribution problem.

Walk through a specific fault

These guides explain common symptoms, what you can safely observe and when to request service.

What changes if the problem continues?

When a commercial space will not stay comfortable, staff and customers feel it before the cause is known. A rooftop unit, split system or airflow problem can affect different rooms in different ways. Note where the problem occurs and when it gets worse so the visit starts with useful evidence.

How we approach commercial hvac

Commercial HVAC is a different job from residential, and not only in size. The equipment runs longer hours, it is usually on a roof, and when it stops the whole building notices before anyone has looked at it.

The systems this covers

Commercial HVAC covers the equipment that conditions a working building, not a house. Most of it sits on the roof or in a mechanical room and is sized for a load that changes through the day.

  • Packaged rooftop units — the single most common commercial system, and the one that suffers most from a dirty condenser
  • Split systems and mini-splits serving offices, server rooms and back-of-house areas
  • Make-up air units, which replace the air an exhaust system removes
  • Kitchen exhaust hoods and the fans that drive them
  • Thermostats, economizers and the controls that decide when any of it runs

The buildings this is for

Offices, retail, schools, churches, medical and dental suites, warehouses and light industrial buildings all run the same commercial equipment, and a rooftop unit that quits in one behaves the same way as in another. Restaurants add exhaust and make-up air to that list, but a kitchen is one HVAC customer among many rather than the whole of it.

What a visit looks at

A no-cool call starts with power and the run capacitor, because those are the cheapest and by far the most common. Next is whether the condenser can reject heat and whether air is actually moving across the evaporator — low airflow can freeze a coil solid and then read as a refrigerant problem it is not. Pressures come last, once the free checks have ruled out most of the possibilities, so a leak gets found rather than topped up.

Serving Peachtree Corners

Peachtree Corners is a technology and corporate corridor in western Gwinnett County, but the office parks and commercial centers along the corridor also carry a steady foodservice base — from corporate cafeterias to restaurants serving the business lunch crowd. These operations depend on refrigeration equipment that runs reliably through every workday.

Commercial Refrigeration Repair

Pierre Refrigeration Services repairs walk-in coolers, walk-in freezers, ice machines, reach-in coolers, and prep tables for restaurants and foodservice operators in the area. Common service calls involve compressors that stopped cycling, evaporator coils that iced over, refrigerant leaks, and ice machines that slowed or stopped production. A technician diagnoses the fault and repairs the equipment before product loss compounds.

Service Area Coverage

Peachtree Corners is built around Technology Park, which means office HVAC, corporate kitchens, and the retail and restaurants serving them. Rooftop units on office buildings and walk-in coolers behind kitchens are the two things most likely to need a technician. Duluth, Norcross and Suwanee are adjacent.

If your refrigeration equipment is down or losing temperature, book a service call. A technician will diagnose the issue and get your equipment back to spec.
