High-quality components are important to keep HVAC equipment like blowers, heat exchangers, dampers secured and functional. Well made parts also have a longer service life, so equipment runs consistently, without frequent breakdowns or costly downtime.
HVAC systems are essential across commercial, industrial, and residential settings, delivering reliable heating, ventilation, and air conditioning. They regulate indoor temperature and humidity to ensure comfort and safety for occupants while protecting products, equipment, and building structures. In addition, HVAC systems play a crucial role in maintaining healthy air quality by circulating fresh air, reducing stagnation, and filtering out dust and contaminants throughout the facility.
At John Evans’ Sons, we manufacture a large selection of standard and custom HVAC springs, wire forms, and precision-stamped components. We have 175 years of manufacturing experience, and we continue to expand our capabilities and services for our customers.
Custom Springs for HVAC Components
We are a single source provider of springs, wireforms, and stamped parts for HVAC applications. At John Evans’ Sons, we specialize in HVAC springs and related components. We’re committed to designing, manufacturing, and providing long-lasting springs that perform consistently, no matter how hard your HVAC system runs.
Our facility includes cutting-edge manufacturing and quality control equipment, so we can provide comprehensive design, manufacturing, inspection, and quality assurance processes in-house.
We source high-quality and corrosion-resistant metals that withstand the moisture, temperature extremes, and high-pressure environments inside HVAC assemblies.
Some of the applications for our custom HVAC components include:
- Airflow Control Systems. Precision constant force springs are used to adjust and control the movement of dampers. This lets air flow throughout the ventilation system at peak efficiency.
- Fire Dampers. Fire dampers are critical for reducing fire risk and maintaining safety code compliance. We develop high-quality, long-lasting springs that control fire dampers and ensure the system’s emergency preparedness.
- Sealing and Insulation. Springs create tension to hold seals and insulation in place. This reduces air leaks and even energy bills.
- Thermal Expansion Solutions. Spring tension holds panels and parts in place while giving them some room to shift due to expansion and contraction as temperatures fluctuate.
- Vibration Isolation. Conventional fasteners, metal components, and loose parts can start to vibrate, rattle, and come apart over time. Custom HVAC springs use compression force to hold assemblies together and minimize noise and wear.
Custom Springs for Fire Dampers
Fire dampers are spring-based assemblies that serve as a barrier in the event of fire. Automatic fire dampers, sensitive HVAC fire dampers, and manual or automated duct fire dampers can prevent fire and smoke from spreading downstream through an HVAC system.
Springs Commonly Used in Fire Dampers
We design and develop the following springs for fire dampers:
- Constant force springs that apply steady force to open and close dampers.
- Spiral torsion springs that activate dampers on demand.
- Custom fire damper springs.
