My Euroart JG168BL dual-zone wine fridge is stuck on an E4 error, which points to a faulty NTC temperature sensor in the upper chamber. The sensor is easy to reach from inside the compartment and will need to be spliced in because the main board is not readily accessible. I need a technician with solid general refrigeration experience who can: • Supply a compatible NTC sensor • Remove the old probe, install and splice the new one neatly (heat-shrink or similar insulation) • Run a full test to clear the E4 code, confirm stable temperatures on both zones and listen for anything else that might need attention I haven’t ruled out other faults, so basic troubleshooting during the visit is expected. If you would rather I order the part myself, let me know—­I...

I already have a working Flex Tool for vanilla Revit that reads a duct-to-grille pick, sizes the flex, and drops in the correct spigot. Since our workflows have moved to Revit Fabrication, I now need that same speed and accuracy inside the fabrication environment. Here is what I expect you to deliver: • Auto-size the flex run from the two picked points on the fabrication duct and the grille connector. • Place the spigot automatically at that location. • If the duct is too flat for the required diameter, select an oval spigot from our existing library and place it instead. • Tie the whole process into the fabrication database so part numbers, materials and sizes come through cleanly and schedules stay correct. • Provide the advanced material and size selec...

Automotive Cabin Heating Thermal Comfort Simulation Fix (STAR-CCM+ .sim + TAITherm Human Thermal / Berkeley Comfort) We are looking for an engineer who can run and troubleshoot an automotive cabin heating thermal comfort simulation using: - Simcenter STAR-CCM+ (.sim) for cabin airflow/temperature fields - TAITherm Human Thermal / HTE + Berkeley Comfort for occupant comfort outputs Task goal (what you need to deliver) We have a simplified cabin model. Under a cold ambient heating scenario, the current results are abnormal: occupant thermal sensation/comfort improves briefly and then becomes colder again (e.g., TS drops toward -1 and continues decreasing). We need you to diagnose the root cause and correct the model setup/coupling/mapping so the outputs are physically reasonable. Target ...

I need a full Manual J load calculation for a multifamily triplex apartment building that will be cooled by three separate central air-conditioning systems. This is new construction so the building does not have any ductwork yet, so the report must factor in brand-new supply and return runs and indicate recommended duct sizing and airflow per room. There are two identical buildings being built next door to each other. 4320 Baudin St and 4324 Baudin St. The upstairs unit is a 3 bedroom 2 bathroom and the downstairs is two separate 1 bedroom 1 bathroom units, however, the architectural plans show the bottom floor as 1 unit (for plan review purposes). There is a fire wall in the middle of the first floor that separates the two 1 bedroom units. One HVAC system will service the front half ...

I’m developing a new HVAC unit and need an experienced mechanical engineer to take it from concept to production-ready design. The engagement centers on full product design, with particular attention to thermal performance inside an HVAC system where end-user comfort is the primary metric of success. You’ll translate my functional requirements into detailed 3D models, run the necessary thermal simulations to verify airflow, temperature distribution, and noise levels, then iterate until we meet comfort targets. Expect to work in common toolchains such as SolidWorks (or similar CAD) and a CFD package like ANSYS CFX/Fluent for the thermal side; if you prefer an equivalent platform, that’s fine as long as the results are exportable. Deliverables • Parametric CAD model ...

Appliance Repair Dispatcher (Remote – Toronto Area) We are a growing appliance repair company serving the Toronto area and are looking for an experienced dispatcher with a background in home services (appliance repair, HVAC, plumbing, electrical). Strong English is required. Russian is a big bonus. ⸻ Responsibilities • Answer inbound calls and book service appointments • Dispatch technicians efficiently and manage daily schedules • Communicate clearly with customers and technicians • Confirm, reschedule, and follow up on jobs • Update job details in the dispatch/CRM system ⸻ Requirements • Proven dispatch experience in home services • Excellent spoken and written English • Strong organization and multitasking skills • Comfor...

I run a wholesale refrigerant distribution company and need a handful of high-authority backlinks that actually move the needle, not a flood of low-value links. Every link must be placed on a real, established industry blog that regularly covers HVAC or refrigeration topics. Quality matters more than volume: I’d rather get five links on respected niche sites than twenty on random directories. If you already have contacts in the HVAC or refrigeration blogging community, mention that when you respond along with a couple of sample placements you’ve achieved for past clients.
