Our Turnkey HVAC Refrigeration Solutions

Every facility is unique, and so are the refrigeration challenges it presents. At Lincoln Associates, we don’t push cookie-cutter systems. We build tailored solutions that match the actual requirements of your application, space, and control strategy.

System Design & Consultation

A solid refrigeration system starts with asking the right questions. We begin every project with a detailed site assessment, examining space conditions, usage patterns, and regulatory requirements to develop a system design that performs as intended.

Our team handles:

  • Load calculations based on real-world operating conditions
  • System configuration for space layout, temperature zones, and energy use
  • Refrigerant planning that accounts for compliance now and down the line
  • Compatibility with trusted manufacturers

You get a custom design that fits your operation, because we engineer it right from the start.

Professional Installation Services

Part of our work involves specifying systems—but we’re also there during installation to ensure they’re built correctly. Our team works directly with contractors, engineers, and facility stakeholders to ensure your installation remains on track and aligned with the plan.

Installation includes:

  • Field coordination to eliminate surprises on site
  • Oversight from people who know how the system’s supposed to run
  • Final commissioning that’s more than a box check—it’s performance validation
  • Certified installation for both medium and low temp systems

We follow manufacturer-certified protocols because that’s what protects your investment.

Maintenance and Support

We’re built for long-term partnerships and back our installs with full maintenance and support options. That’s because we know uptime matters just as much as performance.

Support services include:

  • Preventive maintenance to reduce wear and catch problems early
  • Emergency service with fast response and real troubleshooting
  • Refrigerant and leak management that meets new standards
  • System upgrades and retrofits for older or underperforming equipment
  • Optional service contracts for predictable costs and quicker dispatch

You get a team that knows your system and shows up when it counts.

Medium Temperature Refrigeration Systems

  • Ideal for multi-zone refrigeration in retail, healthcare, and food
  • Energy-efficient options for reduced load and lower utility costs
  • Configurable air distribution, defrost cycles, and control strategies

Medium temp systems cover a wide range of commercial use cases. We’ve installed these systems for beverage storage, floral coolers, medical supplies, and prepared foods. These systems typically operate between 32°F and 41°F, and they must maintain this range consistently to protect the contents.

We configure each system to meet your operational and energy goals, using proven equipment for reliability and long-term serviceability.

Low Temperature Refrigeration Systems

  • Used in food processing, labs, vaccine storage, and more
  • Designed for defrost and humidity control without efficiency loss
  • Available with backup systems and failover controls

If you’re working with frozen goods, biological samples, or pharma-grade materials, your system has zero room for error. Our low-temperature systems reach as low as -40°F and are built with redundancy, humidity control, and thermal stability in mind.

We design these systems for continuous uptime, including mission-critical environments, and pair them with trusted low-temp components from Bitzer and JTS.

Why Choose Lincoln Associates?

We’ve served the Southeast for over 50 years. During that time, we’ve built systems for facilities just like yours, including retail chains, grocery distribution centers, health systems, and more. Our team is experienced and we’re specialized. When you call us, you’re getting a partner who knows the terrain, the codes, and the importance of getting it right.

From the first design meeting to system replacement decades later, we’re built to support your operation long-term. We don’t overpromise. We just engineer it right, install it right, and stand behind it.

Our Trusted Manufacturing Partners

Our partnerships with Bitzer, Kramer, and JTS mean you get access to factory-trained service, top-tier equipment, and systems that stay serviceable well into the future. We don’t cut corners; that’s why the systems we design tend to stay in place longer than most.

Case Studies

Frequently Asked Questions

Food service, healthcare, cold storage, pharma, retail, and industrial environments. We understand the specific performance demands in each, whether it’s holding temp in a floral cooler or ensuring redundancy in a vaccine storage room.
Yes. We specialize in upgrading systems with modern controls and compliant refrigerants. Retrofits can often extend the life of your system and improve efficiency without the cost or disruption of a full replacement.
Emergency support is available through long-term service contracts. We prioritize rapid response for contract clients and understand that downtime in cold storage or processing environments isn’t optional.
All new systems meet current compliance standards, and we’ll help future-proof them for what’s next. We also provide guidance on how refrigerant regulations could affect your existing system over time.

Tube Diameter

Use a caliper or tape measure to determine the outside diameter of the tubes.

If necessary, remove insulation to see the incoming and outgoing lines. Measure the diameter of the outside of the line to help determine connection size.

Standard connection types are MPT (male pipe thread), FPT (female pipe thread), and Copper Sweat Connection. MPT is threaded on the outside, FPT is threaded on the inside, and Copper Sweat is used for soldered connections

Fins per Inch

Using a ruler, count the number of fins on the coil within one inch. Normal fin counts will be between 4 and 14 FPI.

Fin Length

Measure in the direction of the tubes, regardless of which direction the tubes are running.

Fin Height

Measure in the direction of the fin.

Single, Double, and Half Serpentine

Rows are counted in the direction of airflow, no matter how the coil is installed. You can count rows by looking at either the header end or the return bend end of the coil. Note that headers or return bends may not be evenly spaced across the coil.

Fluid coils—hot water, chilled water, and glycol water—regulate building air temperature by heating or cooling air in Air Handling Units (AHUs). Constructed with multiple rows of tubes, typically copper, these coils efficiently transfer heat between air and circulating fluids. They are vital for year-round comfort, accommodating diverse fluids like glycols and thermal oils for varied HVAC needs.

Condenser coils transfer heat from refrigerant vapor to the outdoor air, ensuring efficient cooling in HVAC and refrigeration systems. Constructed from materials like copper or aluminum to maximize heat transfer, these coils are vital for maintaining precise temperature control in industrial and commercial environments.

Steam coils utilize the latent heat of steam, released during condensation from vapor to liquid. They feature efficient condensate management to prevent water buildup and ensure uniform steam distribution. Available in configurations for high and low-pressure applications, steam coils are highly effective for heating air in a wide range of environments.

Evaporator coils absorb heat from indoor air to cool and dehumidify spaces by evaporating refrigerant from liquid to vapor. Located indoors, these coils are essential for maintaining comfortable environments in industrial and commercial settings, offering excellent performance in cooling, process cooling, and dehumidification applications. They are versatile for use in Air Handling Units (AHUs), central systems, or duct installations.
