HVAC Jobs

I need a skilled DesignBuilder practitioner to compare the thermal performance of single- versus double-glazing on the Western and Southern façade of a two-storey office building located in Windhoek, Namibia. I will supply the building geometry, façade dimensions, local double-glazing specifications, occupancy schedules, and a climate file. Please set up the model with custom HVAC parameters that reflect local requirements rather than generic office defaults. Your analysis must quantify: • Annual cooling energy demand • Peak cooling load reduction • Resulting thermal comfort impacts (e.g., PMV/PPD or equivalent indices) When the simulation is complete, deliver two things: 1. A PDF/Excel report that includes both an executive-level summary with clear c...

I’m renovating a retail space in Alabama and need a seasoned general contractor who specializes in commercial projects. Your role will be to handle the permitting process: secure all necessary permits and communicate directly with the permit department to ensure compliance with local regulations. Scope highlights: • Focus solely on obtaining required permits for the renovation. • Collaborate with me and my architect as needed for permit-related documentation. I value clear communication and proactive problem-solving. If you have recent experience navigating Alabama's permitting process, let’s discuss your approach.

I’m scheduling routine maintenance for my split-type air-conditioner and want someone who knows the system inside out. The service visit should cover the essentials that keep the unit running efficiently and extend its lifespan. Please make sure the following tasks are completed during your visit: • Filter cleaning or, if necessary, replacement • Accurate check and top-up of refrigerant levels • Full system inspection, including electrical components, coils, drain line, and overall performance test I expect you to arrive with the tools and basic consumables needed for a standard split AC tune-up, document any additional parts that might be required, and leave the workspace clean when you’re done. If you find anything outside normal wear and tear, let me k...

I'm seeking a professional to create detailed HVAC ductwork drawings and perform Manual J and D calculations for a new construction walkout basement two story single-family home with upstairs and separate downstairs system. Key Requirements: - Accurate ductwork drawings for new residential construction - Manual J calculations for load determination - Manual D calculations for duct design Ideal Skills & Experience: - Proven expertise in HVAC design for residential buildings - Familiarity with industry standards and codes - Proficiency in CAD software for drafting - Strong attention to detail and accuracy Please provide relevant work samples and a brief overview of your approach.

I have already collected all of the field measurements, construction details, and equipment notes for this project and now need everything entered into Wrightsoft so I can hand over a complete, professional-grade Manual J, Manual S, and Manual D package. Here is what I need from you: • Enter my existing data accurately into Wrightsoft Right-Suite. • Run the calculations and generate the full Manual J load report, Manual S equipment sizing, and Manual D duct layout. • Deliver both the native Wrightsoft project file and clean, print-ready PDFs of each report. Acceptance criteria: the room-by-room loads, equipment selection, and duct sizing must line up with the data I provide, show no Wrightsoft error flags, and be ready for submission to code officials or HVAC contrac...

I need a concise Basis-of-Design document that lays out a complete ventilation strategy for a tunnel-type warehouse used purely for storage of goods. Air quality management is the overriding goal, and every recommendation must satisfy current OSHA standards for worker exposure and contaminant levels. The document has to translate those regulatory requirements into clear design parameters—fresh-air rates, airflow patterns, fan sizing, filtration tiers, sensor placement and control logic. Because the building is essentially a long tunnel, please address pressure zoning, potential stratification, and smoke control considerations that differ from a conventional rectangular space. Support the narrative with calculations produced in an HVAC tool you are comfortable with (e.g., Carrie...

Here’s a cleaner version updated for a Combo Walk-In Cooler & Walk-In Freezer project: We are a commercial refrigeration and HVAC company seeking an experienced Electrical Designer / Control Panel Designer to create professional electrical drawings for a Walk-In Cooler & Walk-In Freezer Combo system controlled by PLC. The project includes complete electrical design and drawings for the PLC Control Panel, Walk-In Cooler, and Walk-In Freezer. The electrical design should include: Evaporator units and evaporator fan controls Electric defrost heaters Drain heaters Refrigeration solenoid valves Temperature sensors Termination Sensor Door switches and safety controls Contactors and control relays Circuit breakers and fuses Control power supplies PLC digital inputs and outputs...

I need a qualified HVAC engineer to carry out a detailed assessment of an existing system that is showing signs of poor airflow. The primary goal is to diagnose the root cause of this malfunction and provide a clear, data-driven report that I can hand to my facilities team for follow-up work. During your site visit you will be expected to: • Inspect all major components—air handler, ductwork, dampers, filters, fans, and controls. • Measure static pressure, airflow rates, and temperature differentials to verify performance against design specs. • Identify any mechanical, electrical, or control faults that are contributing to the airflow problem. • Recommend corrective actions ranked by urgency and cost-effectiveness. The final report should include test results, ...

I’m putting together a single, easy-to-follow guide that walks designers and installers through the full Manual J, Manual S and Manual D process. The end product should read like a compact design bible: start with accurate load calculations (Manual J), flow naturally into duct layout and sizing (Manual D), and finish with clear procedures for selecting matched equipment (Manual S). Here’s what I need from you: • A logically sequenced document (Word or Google Docs, deliverable as PDF too) that explains each step in plain language but references the ACCA standards, ASHRAE data tables and any formulas you rely on. • Worked examples—one for a small residence, one for a light-commercial space—showing the numbers from initial inputs through final equipment s...

I need certified A0 chargeman personnel and seasoned mechanical technicians to keep a centralized HVAC & chiller system in Johor running safely and efficiently. The assignment is strictly maintenance-focused and calls for hands-on experience with large-scale chillers and their supporting equipment. The scope covers: • Routine inspections of electrical panels, pumps, cooling towers, and control loops • System cleaning and preventive maintenance, including condenser tube brushing, filter changes, and lubrication • Component replacements or upgrades when wear or performance data indicates the need You will deliver dated service reports, a concise list of findings, and before/after photos for any part you replace or overhaul. All work must comply with Malaysian ele...
