Why Retrofit with ICA
Upgrade Your Heating Plant
Without Starting Over
Most commercial heating systems installed 20-30 years ago are running at 75-80% efficiency — burning 20-25% more fuel than necessary. A well-engineered retrofit replaces the weakest links in your heating plant with modern, high-efficiency equipment while preserving infrastructure that still has useful life.
ICA has been engineering retrofit solutions for commercial and industrial facilities since 1974. We understand the real-world constraints of working in occupied buildings — tight mechanical rooms, limited shutdown windows, and budgets that demand measurable ROI. Every retrofit we design is built around minimizing disruption while maximizing long-term performance.
As a factory-authorized dealer for Patterson-Kelley and other leading manufacturers, we have direct access to the equipment, engineering support, and warranty programs that ensure your retrofit delivers the performance and reliability you expect.
30-40% Energy Savings
Modern condensing boilers, VFDs, and intelligent controls dramatically reduce fuel and electricity consumption compared to legacy equipment.
Minimal Downtime
We stage retrofit work around your building schedule — installing new equipment alongside existing systems before cutting over, so you never lose heat.
Single-Source Accountability
ICA handles engineering, procurement, installation, controls, BAS integration, and commissioning — one contractor, one point of contact, one warranty.
Code Compliant
Every retrofit meets current mechanical, plumbing, gas, and emissions codes. We handle permits, inspections, and documentation required by local authorities.
Our Retrofit Capabilities
Complete Heating Plant
Modernization
From single-component upgrades to full plant rebuilds — ICA provides the engineering and installation expertise to modernize any commercial heating system.
Boiler Replacements
Full boiler replacement engineering and installation — from single-unit swaps to complete central plant rebuilds. We size, select, and install the right equipment for your building load and budget.
Burner Upgrades
Replace outdated atmospheric and power burners with modern, high-efficiency linkageless burners featuring full modulation, low-NOx emissions, and integrated digital controls.
Controls Modernization
Upgrade legacy pneumatic and electromechanical controls to modern DDC platforms. Includes flame safeguards, fuel-air ratio controllers, O2 trim systems, and outdoor reset controls.
BAS Integration
Connect your heating plant to your building automation system via BACnet, Modbus, or LonWorks. Enable remote monitoring, trending, alarm management, and centralized scheduling.
VFD Installations
Install variable frequency drives on combustion air fans, feedwater pumps, and circulating pumps to reduce energy consumption by 30-50% at partial load conditions.
Condensing Technology Upgrades
Convert standard-efficiency boiler plants to condensing technology for 95%+ thermal efficiency. Includes low-temperature return water piping modifications and condensate management.
Retrofit vs. Repair
When to Upgrade
Your Heating System
Not every aging boiler needs to be replaced. But when these warning signs appear, a retrofit typically offers a better return on investment than continued repair.
Rising Energy Costs
If your heating costs have climbed steadily despite consistent building loads, your equipment is likely operating well below its original efficiency rating. Modern condensing boilers operate at 95%+ efficiency vs. 75-80% for older atmospheric units.
Frequent Repairs
When you are calling for repair service multiple times per season, the cumulative cost of parts and labor often exceeds the cost of replacement — especially when accounting for lost productivity during downtime.
Parts Obsolescence
Manufacturers discontinue parts for older equipment. When replacement controls, burner components, or heat exchanger sections become unavailable or require costly custom fabrication, it is time to upgrade.
Code Compliance Issues
Updated emissions regulations, safety codes, and efficiency standards may require equipment modifications that are impractical or impossible on older systems. A retrofit brings your plant into full compliance.
Our Retrofit Process
From Assessment to
Commissioning
Every ICA retrofit follows a structured process designed to deliver predictable results — on time, on budget, and with minimal disruption to building operations.
01
System Assessment
Our engineers inspect your existing equipment, review operating data, and document current performance — identifying inefficiencies, code compliance gaps, and upgrade opportunities.
02
Engineering & Design
We develop a detailed retrofit plan with equipment specifications, piping layouts, controls sequences, and energy savings projections — engineered to minimize construction disruption.
03
Equipment Selection
We source equipment from the brands we represent — Patterson-Kelley, Cleaver-Brooks, and others — ensuring the right match for your load profile, fuel type, and facility constraints.
04
Installation
Our installation crews handle rigging, piping, electrical, gas, venting, and controls. We coordinate with your operations team to stage work around building schedules.
05
Startup & Commissioning
Factory-authorized startup, combustion tuning, safety interlock verification, controls calibration, and operator training — complete with documentation for code authorities.

Frequently Asked Questions
Common Questions About
Heating Retrofits
How much can a boiler retrofit save on energy costs?
Depending on the age and condition of your existing equipment, a modern high-efficiency retrofit can reduce heating energy costs by 30-40%. Condensing boilers operate at 95%+ efficiency compared to 75-80% for older atmospheric units. Additional savings come from VFD installations, improved controls, and better part-load performance. ICA provides detailed energy savings projections as part of every retrofit proposal.
How long does a commercial boiler retrofit take?
Timeline depends on project scope. A straightforward boiler replacement with like-for-like connections can be completed in 1-2 weeks. A full plant modernization with new piping, controls, and BAS integration typically takes 4-8 weeks. ICA stages work to minimize downtime — we can often keep existing equipment running while new equipment is installed alongside it.
Can ICA convert our steam system to hot water?
Yes. Steam-to-hot-water conversions are one of our core retrofit services. Hot water systems offer better efficiency, easier maintenance, and more precise temperature control. We handle the complete conversion including boiler replacement, piping modifications, terminal unit replacement or conversion, and controls integration.
Should we repair or replace our aging boiler?
As a general rule, if your boiler is over 20 years old and requiring frequent repairs, replacement usually offers a better return on investment. Key factors include: annual repair costs vs. replacement cost amortized over equipment life, energy savings from modern efficiency, parts availability for existing equipment, and upcoming code compliance requirements. ICA provides honest assessments — we do not push replacement when repair is the better option.
Does ICA handle all trades for a retrofit project?
Yes. ICA serves as a single-source contractor for heating plant retrofits. We handle mechanical engineering, equipment procurement, rigging, piping, gas connections, electrical, venting, controls, BAS integration, startup, and commissioning. This eliminates coordination issues between multiple contractors and gives you a single point of accountability.
What areas does ICA serve for retrofit projects?
ICA serves all of New Jersey and the greater New York metro area including NYC, Long Island, Westchester, and the Hudson Valley. Our headquarters is in Garfield, NJ with a satellite office in Manhattan. We have completed retrofit projects at facilities ranging from small commercial buildings to large institutional campuses throughout the region.
