HVAC Jobs

I need two separate yet comparable EnergyPlus models of a commercial building so I can study how a pair of alternative design strategies influence daylight and whole-building energy use. My focus on daylighting is two-fold: first, how deeply natural light penetrates the occupied zones; second, how each design mitigates daylight glare. On the energy side, I want a clear breakdown of impacts on the heating, cooling, lighting and ventilation loads. Here is the workflow I have in mind: you create (or adapt) the baseline geometry and envelope, duplicate it into an alternative design with the chosen façade or skylight strategy, then set up the daylighting controls, schedules and sensors. After running annual simulations, you will deliver the raw IDF files, output reports and a concise co...

I'm seeking an experienced MEP designer to create overlays for our complete architectural plans for a commercial building. Needs Pennsylvania seal.

I'm looking for a high-quality air purifier designed specifically to remove allergens. It will be used in a large room at home. Ideal skills and experience: - Knowledge of air purification technology - Experience with allergen removal efficiency - Ability to assess and recommend suitable models for large areas - Understanding of noise levels and energy consumption

Tenho mais de cinco aparelhos de ar-condicionado que precisam passar por uma boa limpeza preventiva. O serviço envolve desmontagem cuidadosa das unidades, higienização de filtros, serpentinas e bandejas de drenagem, além da verificação rápida do funcionamento geral após a remontagem. A maior parte dos equipamentos é split ou de janela (podemos confirmar modelo a modelo no local), portanto quem assumir o trabalho precisa dominar as práticas corretas para ambos os formatos. Planejo executar tudo no mesmo dia, mas podemos dividir em duas visitas caso seja mais seguro para a integridade dos aparelhos. Peço que me informe: • experiência anterior com limpeza de grandes lotes de splits/janelas; Pret...

I need detailed HVAC shop drawings for installation purposes, covering heating, ventilation, and air conditioning systems. The drawings must comply with Australian Standards (AS/NZS) and the Building Code of Australia (BCA). Key Requirements: - Comprehensive HVAC layout - Accurate dimensions and specifications - Compliance with AS/NZS and BCA - Coordination with other systems Ideal Skills and Experience: - Proficiency in HVAC design software - Familiarity with Melbourne's building regulations - Previous experience with shop drawings Looking for a skilled professional to ensure accuracy and compliance.

I have a draft HVAC/BMS integration specification that must plug seamlessly into an AI-driven optimisation platform using BACnet/IP. Before we circulate it to our contractors, I need a senior BMS / HVAC controls engineer to perform a sharp technical review focused on one thing: confirming that every data point, command and alarm defined in the spec will actually play well with the optimisation layer. The document covers chillers, VAVs, FCUs and, most critically, the AHUs, so your comments on these sections will carry extra weight. I’m looking for gaps in point lists, naming conventions, network architecture or sequencing that could block or degrade real-time data flow to the platform. Required background – 5+ years in BMS / HVAC controls engineering for commercial or mixed-us...

My new-construction home in California (just over 4,000 sq ft) needs a complete HVAC design package. The concept I want to pursue is a dual heat-pump arrangement paired with a passive cooling strategy; beyond that, I’m relying on solid load calculations to dictate exact equipment selection, whether that ends up being Carrier, Trane, Lennox, or another equivalent line. Here’s what I need from you: • Full heating and cooling load calculations that respect California climate data and Title 24 requirements • Sizing and selection of two coordinated heat-pump systems plus any ancillary components required for passive cooling integration • Ductwork layout, airflow balancing, and equipment schedule ready for my architect and builder to drop straight into the permit...

I already have stamped, county-approved AC plans for a commercial build in Pinellas County, but the fresh-air intake layout is more elaborate than it needs to be. I need a Florida-licensed Mechanical Engineer to: • Examine the current, permitted drawings in detail. • Identify every opportunity to streamline the outside-air intake while remaining 100 % compliant with the Florida Building Code. My main driver is to cut construction costs without sacrificing code requirements. • Produce a replacement set of drawings—clearly marked as revisions—ready for immediate resubmission to the county. These must carry your Florida PE seal and signature (digital seal is fine). Preferred file format is AutoCAD (DWG) plus a clean PDF package. I will supply the existing plan...

I’m finalising the HVAC design for a new build in Fruitland, Idaho and need an ACCA-compliant Manual J analysis before I order equipment. The plan is to condition the home with two separate Mr. Cool DIY® 5th Generation multi-zone systems, so the numbers have to be accurate. Here’s what I need from you: • A complete Manual J report showing both room-by-room and overall house heating and cooling loads. • Clear capacity recommendations for each of the two multi-zone systems (including your recommendations of how many wall units and the length of line set for each system), including suggested indoor unit sizing per room and total outdoor unit tonnage. • All calculations based on Fruitland, ID outdoor design temperatures and humidity profiles. • Should...
