Commercial HVAC Equipment Custom Built for Performance, Efficiency, and Reliability
QUOTE REQUESTEngineered for Contractors, Built for the Real World
Whether it,s heating, cooling, or complex process environments, Dykier Engineering designs and manufactures custom HVAC systems that outperform off-the-shelf equipment. With over 40 years of real-world air-conditioning experience, we engineer and build solutions for office buildings, manufacturing plants, laboratories, and other demanding commercial applications where efficiency, reliability, and control matter most. Our systems integrate advanced technologies - including makeup air units, high-efficiency cooling, energy recovery DOAS, hydronic systems, and precision air handlers - to deliver some of the most energy-efficient and cost-effective HVAC solutions available today. Our innovative designs are developed and implemented exclusively by Dykier Engineering.
We Solve the Problems Standard HVAC Equipment Can't
Modern buildings demand more than off-the-shelf rooftop units. We engineer HVAC systems to solve the real-world challenges mechanical contractors and consulting engineers face every day.
Energy Code Compliance
Meeting ASHRAE, IECC, and local energy codes with standard equipment is increasingly difficult. We design systems that achieve compliance without sacrificing performance.
High Operating Costs
Oversized or inefficient HVAC systems drive up energy and maintenance costs. Our engineered solutions maximize efficiency and long-term ROI.
Ventilation & IAQ Requirements
Modern buildings require precise outside air control and filtration. We deliver DOAS and makeup air systems that meet ventilation and indoor air quality standards.
Limited Mechanical Space
Tight rooftops and crowded mechanical rooms require compact, purpose-built equipment. Our systems are engineered to fit where standard units won't.
Custom Project Requirements
Every building is different. We design HVAC equipment around your project's loads, layouts, and specifications - without the delays of true custom fabrication.
Long Lead Times
Missed schedules cost money. Our streamlined engineering and manufacturing process delivers custom-configured equipment faster than traditional OEMs.
Dykier Air Engineered Solutions
Our Engineered HVAC Systems: Make-Up Air Units, Energy Recovery DOAS, High-Efficiency Cooling Systems, Hydronic Heating & Cooling, Precision Air Handlers and Custom Engineered Units.
At Dykier Engineering, Inc. we engineer, design, and build air conditioning and heating systems - from office building comfort heating and cooling to process cooling for manufacturing. Our experience stretches out to 35 years of being in the industry. The world of air handling is changing. Energy is more expensive and will get more so. We engineer systems that get maximum cooling from the least possible energy. Techniques like indirect cooling, duct size engineering, and utility rebate programs deliver some of the most energy efficient systems on the market. Dykier Engineering has provided the most exceptional air handling solutions for commercial, industrial, and laboratory markets. We believe that engineering is the difference between a cooling system that merely works and one that exceeds performance expectations for years to come. Whether it's cooling or heating systems, custom designed equipment is what sets Dykier Engineering apart from the competition. We engineer, design, and construct air conditioning and heating systems for a wide range of commercial clients - from office building comfort heating/cooling, to process cooling for manufacturing and laboratories.
Makeup Air Units
Dykier Makeup Air Units supply 100% outdoor air to your building creating comfortable building environments with superior indoor air quality.
Makeup Air Systems can be customized with cooling and heating options, filtration options, direct digital control, and sizes and configurations to meet your specific building needs.

Energy Recovery DOAS
We design DOAS to capture the energy in the airstream that would otherwise be exhausted to the atmosphere and use it to pre-heat or pre-cool the outdoor airstream.
Dykier Energy Recovery Systems are ideal for applications requiring fresh outdoor air, energy efficiency, humidity control, and occupant comfort.

High Efficiency Cooling
Energy efficiency is a combination of many design elements that lead up to the savings you seek. Elements like:
Air and water source heat pumps, Fan System Optimization, Energy recovery heat exchangers, Variable capacity compressors, New refrigerants, Low pressure coils, Evaporative cooliing, and HEPA Filtration.

Hydronic Systems
We use free cooling by incorporating direct and indirect evaporative cooling. Intelligent use of water systems eliminates the energy hog of traditional DX cooling.
Our energy saving systems use a cooling tower, condenser, water piping, control valves, and water coils to provide cooling for up to 80% less than traditional DX cooling.
