While conversations around decarbonization often focus on large-scale electrification projects or renewable energy investments, many opportunities begin with something much more practical: optimizing the HVAC systems already in place. For many commercial facilities, especially older buildings, HVAC systems were designed around worst-case scenarios and long-term safety margins. Over time, that approach has led to systems… June 1, 2026
Maddock Industries is proud to announce a new partnership with Nyle Water Heating Systems, expanding its lineup of high-efficiency mechanical solutions with commercial heat pump water heating technology. As building owners, engineers, and contractors continue looking for ways to improve efficiency and reduce long-term energy consumption, heat pump water heaters have become an increasingly important… April 15, 2026
US Draft Co. is a leading manufacturer of engineered draft control solutions designed to support safe, efficient, and code-compliant venting in modern heating systems. As boiler and appliance technologies evolve (especially with high-efficiency and multi-unit systems) the complexity of venting has increased. US Draft Co. addresses these challenges with integrated systems that actively manage airflow,… February 3, 2026
In commercial construction, industrial plants, municipal infrastructure, data centers, and virtually any project where piping penetrates walls and floors, the quality of your sealing system matters. That’s where LINK-SEAL® modular pipe sealing systems come in—and why sourcing them from Maddock Industries is a smart choice for engineers, contractors, and building owners alike. What Is LINK-SEAL?…

Building owners and operators are facing a growing need to cut energy use and lower carbon emissions — Danfoss solutions can help. In cities like Chicago, large buildings over 250,000 square feet must meet benchmarking requirements that set deadlines for measurable reductions in consumption. For facility owners, this means finding ways to improve efficiency without… September 30, 2025
In an ideal world, a hydronic system operates quietly in the background, heating and cooling a building without drawing attention to itself. But in reality, noise and vibration are two of the most common and frustrating issues facility managers and mechanical contractors face. From the sudden jolt of water hammer to the low hum of… September 19, 2025
When a commercial HVAC system relies on glycol to prevent freezing, a reliable method is needed to maintain system pressure. That’s where Armstrong’s GLA Units come in. These automatic fill units are designed to maintain proper pressure in glycol-based systems while preventing contamination, overflow, or system failure. At Maddock, we stock Armstrong GLA units—ready to… July 28, 2025
Garlock’s LINK-SEAL modular seals (models LS-200 through LS-650) are widely used to create permanent, hydrostatic seals around pipes and conduits where they pass through walls, floors, and other barriers. These modular seals, made from interlocking rubber links compressed by bolts, provide a gas- and water-tight seal that withstands up to 20 psi of water pressure,… July 14, 2025
When selecting a Garlock LINK-SEAL, two main factors influence performance and longevity: choosing the right model based on the pipe-to-wall gap and selecting the right material for the environment. Garlock offers LINK-SEALs in sizes from LS-200 to LS-600 and beyond, each suited to different pipe sizes and conditions. Note: If your size or configuration isn’t…
