Custom HVAC Design & Installation Tailored to Your Needs
Commercial properties require more than standard heating and cooling; they demand a calculated approach to air distribution, ventilation, and thermal control. A "design-build" approach integrates the engineering and installation phases into a single workflow — view our gallery today. This method eliminates the disconnect that often occurs when separate architects, engineers, and contractors attempt to collaborate without a unified vision.
In the Rogue River area, where summer temperatures frequently reach 90°F and winters bring consistent rainfall, the load calculation for a commercial building must be precise. An off-the-shelf system will likely fail to handle the dynamic thermal loads created by large glass storefronts, high-occupancy zones, or machinery that generates heat.
A proper design-build project focuses on the following technical aspects:
- Load Calculations: We perform rigorous calculations (Manual N) to determine the exact heating and cooling capacity required. This prevents short-cycling caused by oversized units and the inability to maintain temperature caused by undersized units.
- Zoning Strategies: Commercial buildings rarely have uniform temperature needs. A server room requires constant cooling, while a conference room has variable needs based on occupancy. We design zoning systems using VAV (Variable Air Volume) boxes or VRF (Variable Refrigerant Flow) technology to grant independent control over different areas.
- Ventilation and IAQ: Adhering to ASHRAE standards for fresh air intake is mandatory for commercial spaces. We design intake and exhaust systems that ensure adequate air changes per hour, filtering out pollutants and preventing "sick building syndrome."
- Ductwork Engineering: Improperly sized ducts restrict airflow and increase static pressure, leading to blower motor failure. Our designs include custom ductwork fabrication specifications to ensure efficient airflow delivery to every register.

What You Can Expect: Process, Timeline, and Inclusions
Engaging in a commercial HVAC design-build project involves a structured timeline to ensure the final product meets all operational goals. Unlike residential replacements which can often be completed in a single day, commercial projects require planning, fabrication, and coordination.
The scope of work typically includes the removal of old infrastructure, structural reinforcement if necessary, and the integration of new controls. Transparency regarding the timeline is critical for business continuity. While small system change-outs may take a few days, comprehensive design-builds for larger facilities may span several weeks from initial design to final commissioning.
Your project scope will generally cover:
- Site Assessment and Feasibility: A thorough walkthrough to inspect current structural integrity, electrical capacity, and potential locations for rooftop units (RTUs) or ground-level pads.
- Engineering Prints: Creation of detailed mechanical drawings that map out unit placement, duct routing, gas lines, and electrical connections.
- Equipment Procurement: Sourcing commercial-grade equipment such as packaged units, split systems, or chillers that match the specified SEER and IEER efficiency ratings.
- Project Management: Coordination of logistics, including crane rentals for lifting heavy equipment onto rooftops and scheduling road closures if necessary for safety.
Our Installation Process: Simplified Steps for Your Convenience
We utilize a systematic approach to installation that prioritizes safety and efficiency. By following a strict protocol, we minimize the risk of errors and ensure that the system performs according to the design specifications immediately upon startup.
- Initial Consultation and Discovery: The process begins with identifying your specific pain points, budget parameters, and long-term facility goals. We gather data on building orientation, insulation levels, and peak occupancy times.
- System Design and Engineering: Our team develops a custom mechanical plan. This includes selecting the appropriate tonnage and creating a layout that optimizes airflow while remaining unobtrusive to the building’s aesthetics.
- Permitting and Compliance: Before any physical work begins, we handle the submission of plans to local building departments to secure necessary mechanical and electrical permits.
- Demolition and Preparation: Existing equipment is safely disconnected and removed. We prepare the mounting surfaces, ensuring roof curbs are watertight and structural supports are adequate for the new weight load.
- Installation and Fabrication: Technicians install the main units, fabricate and seal ductwork, and run refrigerant and gas lines. Electrical connections are made by licensed professionals to ensure code compliance.
- Commissioning and Testing: Once installed, the system is not merely turned on. We balance the air, test thermostats and sensors, verify refrigerant charge, and ensure all safety controls are functioning.
- Handover and Training: We walk facility managers through the operation of the new system, explaining how to use programmable thermostats or building automation systems to maximize efficiency.
Deciding Between Repair and Replacement: A Guide for Business Owners
One of the most difficult decisions for a facility manager is determining when to stop repairing an aging system and invest in a new design-build solution. While repairs may offer a lower short-term cost, they often lead to higher cumulative expenses due to inefficiency and frequent breakdowns.
Commercial systems generally have a lifespan of 15 to 20 years. As they age, heat exchangers can crack, compressors lose compression, and electrical components degrade. Continuing to patch a failing system can pose safety risks and result in unpredictable downtime that impacts revenue.
Consider the following factors when evaluating your current HVAC assets:
- The 50% Rule: If the cost of a necessary repair approaches or exceeds 50% of the value of the equipment, replacement is usually the wiser financial decision.
- Rising Energy Bills: As equipment wears, it consumes more electricity to produce the same amount of cooling or heating. A sudden spike in utility costs often indicates that the system’s efficiency has degraded significantly.
- Frequency of Service Calls: If your system requires professional attention more than twice a year outside of standard maintenance, it is likely nearing the end of its useful life.
- Tenant Complaints: Inconsistent temperatures and humidity issues can lead to dissatisfied tenants or employees. If the current design cannot maintain comfort levels, a redesign is necessary.
- Refrigerant Phase-Outs: Older systems often utilize refrigerants that are being phased out or are already banned. Repairing leaks in these systems can be prohibitively expensive due to the scarcity of the refrigerant.
Understanding Local HVAC Regulations and Optimal Timing
Navigating the regulatory landscape in Rogue River and the surrounding region is a critical component of any commercial project. Commercial HVAC work is subject to stringent codes regarding energy efficiency, ventilation rates, and environmental safety. Failure to obtain the correct permits or adhere to code can result in fines, project shutdowns, or issues when trying to sell or lease the property later.
We ensure strict adherence to:
- Energy Codes: Oregon has specific energy conservation codes that dictate minimum efficiency standards for new equipment installations. This often involves requirements for economizers, which use cool outside air to condition the building, reducing the load on the compressor.
- Seismic Bracing: Given the geological characteristics of the Pacific Northwest, commercial units—especially those on rooftops—must be properly anchored to withstand seismic activity.
- Environmental Regulations: Proper disposal of old equipment and recovery of refrigerants are mandated by federal and state laws to protect the environment.
Seasonality and Scheduling:
The climate in Rogue River affects the ideal timing for installation.
- Spring and Fall: The "shoulder seasons" are the most strategic times for major HVAC projects. With moderate temperatures, disrupting the heating or cooling system for installation has the least impact on building occupants.
- Summer Constraints: Attempting a major replacement during the 90°F+ heat of summer puts immense stress on business operations. Furthermore, technician availability is often lower due to high demand for emergency repairs.
- Winter Considerations: The wet winters in the region can complicate rooftop installations. Waterproofing roof curbs during active rainfall requires specialized care to prevent leaks. Stone Heating and Air plans around weather forecasts to ensure the building envelope remains secure throughout the process.
