repairs & RETROFITS

Depending on the specific conditions, retrofits and repairs have several benefits compared to installing new equipment or systems.

Many Factors To Consider

Repairs or retrofitting is the correct answer for some facilities, but it can be overwhelming to determine this on your own.

The decision to repair or replace depends on various factors, such as the extent of the damage, the age of the system, energy efficiency considerations, and long-term cost analysis.

    Your trusted partner

    Consulting with a qualified mechanical contractor can help you assess the situation and make an informed decision that aligns with your needs and goals.

    With over 77 years of helping clients determine if a retrofit, repair, or renovation is a good choice for their facility, we can evaluate your current system to see if it is the right choice for you.

    Sample projects


    Replaced the leaking main (king) liquid supply valve to the plant and all dock evaporators with new stainless steel evaporators.

    Leaking Main Liquid Supply Valve: 

    The main liquid supply valve is a crucial component in the system that controls the flow of liquid to different parts of the plant. This valve was damaged and leaking, allowing the fluid to escape where it should not, leading to inefficiencies. Due to the issues caused by the leaking valve, it was decided that the best course of action was to replace it entirely with a new one. 

    Replacing All Dock Evaporators:

    Evaporators are devices used to convert a liquid into vapor by heating it. They are crucial in many industrial processes, including distillation, refrigeration, and water treatment. Stainless steel evaporators were chosen for this job for their better durability, corrosion resistance, and improved performance over the previous materials. 


    There were necessary modifications when we removed and installed a new Carrier chiller at a specialty material manufacturing plant.

    After we supplied and installed a new Carrier chiller, we made necessary piping modifications using Victaulic. We also modified the electrical to accommodate the new chiller, including a new conduit and wire to an existing switchgear bucket. Then we insulated the new pipe to match the existing one with an aluminum jacket.

    “Exceptional is not a stretch to describe your service and team. You are true to your word and philosophy. It shows in the people I have interacted with that work for you. Today’s facility management is so much about partnering with service providers. Thank you for all that you and your company provide to ours.”

    Which HVAC Equipment Works Best for Retrofitting?

    While recommendations can vary depending on your type of HVAC equipment and operations, packaged rooftop units and chillers are among the best options for a retrofit plan. 

    Packaged Rooftop Units (RTUs): Since RTUs are self-contained units, they are suitable for many retrofitting applications.

    • Airside economizers
    • Cooling capacity controls
    • Supply fan speed controls
    • Demand-controlled ventilation

    Chillers: There are several options available to improve their performance, energy efficiency, and functionality.

    • Replace old screw compressors
    • Adding condenser fan controls
    • Chiller Controls and Sequencing
    • Refrigerant Retrofits
    What is the difference between repairing and retrofitting?


    Repairing refers to fixing or restoring a malfunctioning or broken component or system within the HVAC system. When a specific HVAC component fails or shows signs of malfunction, a technician identifies the problem and takes appropriate actions to restore it to proper working condition. Repairs can range from simple fixes like replacing a faulty sensor to complex repairs like troubleshooting electrical issues.


    Retrofitting, conversely, involves making significant modifications or upgrades to an existing HVAC system. The end goal is to improve its performance, efficiency, or functionality. Retrofitting goes beyond fixing a broken component and focuses on enhancing the overall system to bring older or outdated HVAC systems up to modern standards. It often involves a thorough assessment of the existing system, determining areas for improvement, and executing changes that align with the specific goals and requirements of the building.

    Will retrofitting my HVAC system save me money?

    In many cases it will. The end goal of any retrofitting service is to improve your equipment’s performance, efficiency, or functionality. Cost savings from a retrofit plan can be significant.
