We install, replace, upgrade, diagnose, and support refrigeration systems for homes, multifamily properties, and commercial buildings.
That includes ductless and ducted heat pumps, variable refrigerant flow (VRF) systems, air-to-water systems, geothermal heat pumps, heat pump water heaters, and refrigerant-based equipment that needs to operate reliably in real conditions.
A refrigeration system moves heat using refrigerant. In homes and buildings, that can include heat pumps, ductless mini-splits, VRF systems, air-to-water systems, geothermal heat pumps, heat pump water heaters, and heat recovery equipment used for heating, cooling, or water heating.
These systems depend on refrigerant flow, airflow, controls, piping, electrical conditions, and distribution all working together to maintain stable temperatures and reliable operation.
Refrigeration performance can also affect domestic hot water systems, commercial hot water systems, and larger heat pump chiller and heat recovery systems.
Our refrigeration work covers heat pump and refrigerant-based systems across homes, buildings, and facilities.
These systems work together. A problem in refrigerant flow, airflow, controls, piping layout, hydronic distribution, or heat transfer can affect how the whole system performs. For larger building applications, see our commercial mechanical services.
These service pages explain common refrigeration, heat pump, and heat-transfer work in more detail.

Structured diagnostics for refrigerant performance, airflow, controls, lockouts, temperature instability, rising energy use, and unclear replacement decisions.
Refrigeration systems usually fall behind when refrigerant charge, piping layout, airflow, coil condition, controls, defrost behavior, electrical conditions, or distribution are not verified under real operating conditions. The result is often poor comfort, long runtime, rising energy use, lockouts, or premature replacement pressure.
In many cases, performance issues begin earlier, when refrigerant charge, airflow, piping layout, or controls are never fully aligned with how the system actually needs to operate.
When the cause is unclear, a System Assessment can help identify whether performance is being affected by refrigerant conditions, airflow, controls, system design, operating drift, or the way the equipment is applied.
Heat pumps and cooling systems often show signs before they fail completely.
Heat pumps struggle to maintain temperature during winter demand even though the system is running.
Fault codes, protective shutdowns, or repeated resets can point to refrigerant, airflow, electrical, or control conditions.
Some rooms or zones stay noticeably different from others during heating or cooling operation.
Defrost cycles seem more frequent or last longer than expected during cold-weather operation.
Electrical consumption increases during heating or cooling without a clear change in weather or building use.
The system runs for long periods without delivering stable comfort across the space.
Every project follows the same four-stage standard: PLAN, INSTALL, VERIFY, and SUPPORT.
We document existing conditions, evaluate refrigerant system layout, confirm demand, review airflow or hydronic distribution, identify constraints, and define performance targets before major work begins.
We install refrigeration systems with proper piping, support, condensate management, code-compliant layout, manufacturer requirements, electrical coordination, and service access in mind.
We check safety and performance through refrigerant charge verification, pressure checks, airflow review, temperature measurement, controls, defrost behavior, and recorded baseline conditions.
Service & Support helps compare future system conditions against documented baseline readings and identify performance drift before it becomes a larger failure.
A refrigeration system should be evaluated when performance becomes inconsistent, unstable, inefficient, or difficult to explain. Common triggers include poor cold-weather heating, repeated faults, uneven zone temperatures, long defrost cycles, rising electrical use, constant runtime, refrigerant concerns, or cooling failure during occupied operation.
If these conditions are present, a structured System Assessment can help determine whether the issue is refrigerant charge, airflow, controls, defrost behavior, system application, or the way the equipment is being used.
Refrigeration systems interact with airflow, hydronic distribution, domestic hot water, electrical capacity, controls, and building load. A heat pump or refrigerant-based system may be affected by ductwork, water temperatures, hot water demand, defrost behavior, control sequence, or connected mechanical equipment.
Airflow restrictions can reduce heat pump capacity. Duct design can limit coil performance. Control sequences can affect staging and lockouts. Hydronic integration can affect how an air-to-water system performs.
Refrigeration performance can also affect residential comfort, multifamily stability, commercial building operation, commercial domestic hot water, and heat recovery opportunities.
Some situations need prompt diagnostic support, especially when heating, cooling, or building operation is affected.
Before replacing refrigeration equipment, the system should be checked for load, airflow, refrigerant charge, piping layout, controls, defrost behavior, electrical conditions, distribution, temperature requirements, and service access. Replacement works best when the new equipment solves the actual operating condition.
Equipment is often replaced when the real issue starts somewhere else in the system.
A structured assessment can identify airflow restrictions across coils, incorrect refrigerant charge, improper piping configuration, control or defrost cycle issues, distribution limitations, hydronic temperature mismatch, or startup conditions that were never fully confirmed.
Addressing those conditions first can prevent unnecessary replacement and lead to a more stable result. Learn more about the System Assessment process.
When a system is evaluated and confirmed clearly, there is documentation behind the work.
This documentation is part of The Neveu Standard, the framework we use to plan, install, verify, and support system performance.
A refrigeration system is confirmed through measured startup and operating checks. That includes refrigerant charge verification, airflow and static pressure review, pressure measurements, temperature readings, control behavior, and operating checks under real conditions rather than visual assumptions alone.
This is part of The Neveu Standard, which requires systems to be verified instead of assumed.
A2L refrigerant readiness means the system follows current code, manufacturer instructions, refrigerant volume limits, and related safety practices for refrigerants with lower global warming potential (GWP) such as R-32 and R-454B.
A2L changes can affect installation planning, service access, equipment selection, and long-term support. Related systems may also need review under mechanical system and Service & Support standards.
A refrigeration system should be evaluated when performance becomes inconsistent, energy use rises, fault conditions begin appearing, or equipment no longer meets heating, cooling, hot water, or process temperature requirements. Systems often show drift before full failure occurs.

A Refrigeration System Assessment is a structured evaluation of how the system is operating. It identifies performance conditions, documents current operation, and helps define what needs attention before problems become larger failures or unnecessary replacement decisions are made.
It is one part of the broader System Assessment process.
Yes. A heat pump water heater uses a refrigerant-based heat pump cycle to move heat into domestic hot water. It also belongs under domestic hot water because the final purpose is hot water production.
Learn more about Heat Pump Water Heaters and Domestic Hot Water Systems.
Yes. Heat pump chillers use the refrigeration cycle to move heat into or out of water. In commercial buildings, they can support hydronic heating, chilled-water cooling, heat recovery, domestic hot water preheating, and process heat opportunities.

If your system is not operating the way it should, there is usually an underlying condition behind it.
A Refrigeration System Assessment helps identify how the system is operating, where performance is being lost, and what needs attention before the problem gets worse.
