Topic: What to Do If Your AC Blows Air but Doesn’t Cool the Room?: t the cooling just wasn’t happening. At first, I assumed the unit was broken beyond repair. But after checking the manual, I found out that this is one of the most common AC issues, and in many cases, it can be fixed with simple troubleshooting. Common Reasons Why an AC Doesn’t Cool Dirty air filter – Blocks airflow and reduces cooling efficiency. Low refrigerant level – If there’s a leak, the system won’t cool properly. Blocked condenser coils – Dust and debris prevent heat exchange. Wrong thermostat settings – The AC may be set to “fan only” mode. Poor insulation – Cold air escapes while hot air enters. Step-by-Step Troubleshooting 1. Check the Thermostat Settings The manual recommends verifying that the unit is set to “cool” mode and the temperature is lower than the room’s current temperature. Once, I had it set to “fan,” which explained why it wasn’t cooling. 2. Clean or Replace the Air Filter According to the manual, a clogged filter is the most frequent cause of weak cooling. I replaced mine, and airflow improved instantly. 3. Inspect and Clean Condenser Coils The manual explains that outdoor condenser coils should be free of dirt. I carefully cleaned mine with a soft brush, and the cooling power came back. 4. Check for Refrigerant Leaks The manual notes that low refrigerant levels require a professional. I noticed frost on the lines, which was a sign of a leak. After repair and refill, the AC worked perfectly again. 5. Improve Room Insulation Sometimes the AC isn’t the problem. The manual advises closing windows, doors, and blinds to keep cool air inside. Doing this made a noticeable difference. My Experience At first, I thought I needed a brand-new AC. But by following the manual — cleaning filters, checking settings, and maintaining the condenser — I solved the problem without expensive repairs. Since then, I clean the filters monthly and keep an eye on coil cleanliness. FAQ Why does my AC blow air but not cool? – Most often because of clogged filters, dirty coils, or low refrigerant. Can I fix this at home? – Yes, by following the manual: check thermostat settings, clean filters, and ensure proper airflow. When should I call a technician? – If the refrigerant is low or the AC still doesn’t cool after basic fixes.…; Added by Karl Mozaik to GeometryBin at 4:12am on September 27, 2025

Comment on: Topic 'Trees missing': three categories, each one corresponding to different shapeType_ input:- polygons (shapeType_ = 0): anything consisted of closed polygons: buildings, grass areas, forests, lakes, etc - polylines (shapeType_ = 1): non closed polylines as: streets, roads, highways, rivers, canals, train tracks ...- points (shapeType_ = 2): any point features, like: Trees, building entrances, benches, junctions between roads... Store locations: restaurants, bars, pharmacies, post offices... So basically when you ran the "OSM shapes" component with the shapeType_ = 2, you will get a lot of points. If you would like to get only 3d trees, you run the "OSM 3D" component and it will create 3d trees from only those points which are in fact trees. You can also check which points are trees by looking at the exact location on openstreetmap.org. For example: Or use the "OSM Search" component which will identify all trees among the points, regardless of whether 3d trees can be created or not.However, when it comes to 3d trees there is a catch: Sometimes the geometry which Gismo streams from OpenStreetMap.org does not contain a "height" key. Or it does contain it but the value for that key is missing.OpenStreetMap is free editable map database, so anyone with internet access and free registered account on openstreetmap.org can add features (like trees) to the map database. However, regular people sometimes do not have height measuring devices which are needed for specific objects as trees.So "OSM 3D" component will generate 3d trees from only those tree points which contain a valid "height" key.However, a small workaround is to input a domain(range) into the randomHeightRange_ input of "OSM 3D" component (for example the following one: "5 to 10"): This will result in creation of other 3d trees which do not have defined height, by randomizing their height. randomHeightRange_ input can also be applied to 3d buildings, and it is definitively something I need to write a separate article on. In the end it may be that nobody mapped the trees in the area you are looking for. After you map a tree to openstreetmap.org then it will instantly be available to you or any other user of Gismo. I will be adding some tutorials in the future on how this can be done. But probably not in the next couple of weeks. Let me know if any of this helps, or if I completely misunderstood your issue.…; Added by djordje to Gismo at 3:52am on February 8, 2017

Topic: Complex geometry Glazing issues: ooking for an efficient way to perform glazing of complex shapes. I've only followed the Energy modelling workshops so far so i may have missed some essential components or workflows to achieve my needs. But i've made an attached definition with all my current attempts to get a proper HBzone with the numerous windows faces i will always have to deal with in this project. I first thought that i was not using the HBObjWGZ correctly, then after some readings it was maybe an upgrading issue, then effectively i had my Therm 7.5 that needed to be reinstaled, but then ... I must be missing an essential HB tricks or workflow i guess ... So I divided my attempt in two series : - The Serie 1 : is a simplier version of the project step i'm working on but i'd be glad to achieve it first ! - The Serie 2 : is the real final direction of the project, which consist in sorting/dispatch faces to windowon one side and to an other material on the other, according to the winter sun and a pourcentage param. Despite it is more complicated than the Serie one, it seems seems to create the same diversity of issues. Until now, with the 5 different combinations of Serie 1, and the 3 of Serie 2, with and without using the different Glazing/window components, here are the logs i got from both HBZone component or OpenStudio component: From OpenStudio - "1. The simulation has not run correctly because of this severe error: ** Severe ** BuildingSurface:Detailed="00073E23257843B6A948", invalid Construction Name="ETFE" - has Window materials.">> Has to deal with the way i'm trying to assign too early a customized EPConstruction material ? Done it wrong ? I tried to reload it in the library but doesn't change anything... From OpenStudio - "1. The simulation has not run correctly because of this severe error: ** Severe ** BuildingSurface:Detailed="000579CD749E46DFA5EA", invalid Construction Name="EXTERIOR WINDOW" - has Window materials.">> Is it an issue in the way i define my surfs both as "WINDOW" (5) for srfType and Outdoors on the same component ? From Create HBZone -"1. Solution exception:'EPZone' object has no attribute 'shdCntrlZoneInstructs'" >> Happens when i try to introduce my ETFE EpMaterial after creating my first HBZone, with a Set EP Zone Construction, so this material seems to be not working either before and after trying to create an HB Zone From Create HBZone- "1. Solution exception: 73df51a3b2144b1e858b has been moved, scaled or rotated."If you need to move or rotate a Honeybee object you should use Honeybee move, rotate or mirror components. You can find them under 12|WIP tab. >> >> wich seems to exist in some on other thread Here and was a coding bug supposed to be fixed. And last but not least ... From OpenStudio - "1. The simulation has not run correctly because of this severe error: ** Severe ** checkSubSurfAzTiltNorm: Outward facing angle of subsurface differs more than 90.0 degrees from base surface.2. The simulation has failed because of this fatal error: ** Fatal ** GetSurfaceData: Errors discovered, program terminates" . I'm attaching the file with each attempt in this post. The definitions are disabled and the log already copied separatly so there is no need to compute each of them to see what's wrong. If someone from the beginner to one of the Kings of HoneyBee has any relevant answer/solution to this attempt with complex geometry Issue it will be really nice for me so i could to move forward !!

Comment on: Topic 'Into to Grasshopper Webinar - feedback, recording, and files': his comes in the form of an HTML page with links to every component, so you will need to view it in your web browser. (I use Chrome and it doesn't seem to be working correctly, but when opened in IE its fine.) 2) Included in each help topic for each component is the Inputs and Outputs descriptions and data types. 3) You supply the data. What you supply and how you supply it is for you to decide. There are umpteen different ways. Are you asking for a list of those ways for each input? 4) Points can either be Rhino objects or 3D co-ordinates. To create a point you can use any of these methods, but it mostly comes down to user preference. I like using Panels as this displays outside of the component. 5) Because of the nature of vectors they represent magnitude and direction but they don't have an independent location, so there is a component that will display vectors in Rhino. 6) The user. 7) There is a Primer on the front page. Here you find the Basics, but because GH is ever evolving in its current beta state you might find things that aren't relevant any more or simply don't work the same. And here is the reason why nobody is writing an update because it could be soon out of date. 8) Importing images by either dragging them from explorer onto the canvas or right click context menu Image... 9) Single line = Single Item of Data. Double line = Multiple items of data on the same Branch. Dashed Double Line = Multiple Data on Multiple Branches. 10) User preference 11) Toolbar management is probably the bane of David's life. Most things are logically placed. For example the Curve Tab, Primitives are any simple curve types that you are creating from scratch. Similarly Splines is for more complex curve types created from scratch. Analysis is where you find components that are finding answers supplied by curves, control points, curvature, parameters, end points etc. Division is a subset of this category but has a group of its own. And Utilities is where you find curve related actions that you want to perform, offsetting, rebuilding projecting, exploding etc. 12) I would image it would have been the Point On Curve component in Curve>Analysis. Why that group? You are not putting a point on a curve you are analysing a curve for the location of a point based on some parameters that you are supplying. For example "what is the mid point?" I hope this goes some way towards answering you questions. No doubt this will have generated more so don't be afraid to ask, it took me several releases of Explicit History (aka Grasshopper) before I realised what the egg did, it never occurred to me that I could put my objects into Rhino when I was finished. Or the fact that I could use panels to 'see' data outputs. Al the best, Danny…; Added by Danny Boyes at 3:48am on December 9, 2010

Comment on: Photo 'capture_032': can work in any node of a given hierarchy tree (loaded in your work session) by making the node "active". "Nodes" can be other things as well (like workplane, clip definitions etc). Why to do that weird thing? Well, think any design being "flat" > meaning that all objects are placed in a single file (and in a single layer). Not that good > although the items are present you barely can handle them (because power is nothing without control, he he). Let's go one step further: we can start classifying objects in "groups" (like a directories/files organization in any O/S). This means, in MCAD speak, creating assemblies (a void thing kinda like a directory) that contain components/entities (kinda like files). Several steps further we end up with severely nested "arrangements" of entities (an assembly could be parent of something and child of something else). For instance, it could be rather obvious the logical classification of a "geodetic" (so to speak) structure like this : a 40000m2 "hangar" defining some thematic park. I mean : a void master that owns 4 equal void segment sets that own 4 "legs" that own various geodesic structural members + cables + membranes + you name it etc etc. Each "leg" owns the concrete base (Shared) and a rather complex set of objects. Notice that some tensile membrane "fixture" combos (see above)...act as perimeter light fixtures as well...meaning that the membrane tension plate may could be a child of a void "light" parent...or may could be a "stand alone" assembly etc etc. These arrangements can be internal (belonging in, say, a x node within the current active file) or external (belonging in a y node within another file). If they deal with the same (topologically speaking) object they define clusters of Shared entities (or variations)- where only the view transformation matrix changes (in the simple scenario, he he). For instance the disk shown above is a Shared Assembly that owns the bolts, the plates, the tension member etc etc. Selective Instancing allows modifying some attributes without affecting the topology (i.e. the geometry). The whole (terrible) mess is controlled by some tree like "dialog" (in Catia is "transparent") that is called Structure Browser. By controlled I mean (1) display/display mode with regard any tree member combo/selection set (assembly and/or component) in any View (2) clip state control (3) active status (for modifications/variations) (4) workplane control (5) drag and drop ownership control (6) ....

Comment on: Topic 'Randomness...paperPavillon': this occasion, but it could be converted for DT in no time). Requires some minutes more as regards ... some things, but the usual update is due to some days. Bad news: it's C# Good news: User's Manual : 1. That thing (the C#, not me) after sorting (in a "sequential way", so tho speak) the panels (their order was chaotic) allows you to start the massacre by locating a focus of interest (and the user controllable +/- Range derived from it).2. The Range is variable (obviously) and takes care not to exceed the indices of the panel list (OK, that's elementary). 3. If you click the right button (Sadistic Q: where is it? he he) things are deleted and a new constantly self-updating list is your new List. Thus the massacre of panels is totally controllable. An autoZoom thing is also included (free of charge, but it's a bit nerve braking). Zoom factor is variable as well. 4. Then you move over (via the index slider) and start the massacre again. Notice the change of Range. 5. If you turn begin to false (initialization) and then begin to true > start all over again. 6. The other C# thing allows you to increment the index slider in a rather more convenient way. It's a bit weird: it uses delegates (A delegate is an object that knows how to call a method) and events (An event is a construct that exposes just the subset of delegate features required for the broadcaster/subscriber model - but don't ask what this means, he he) in order to talk with your slider (with a defined NickName) and perform the required value control. NOTE: without realizing it you've just (indirectly) asked one of the most important questions even exposed in this Noble Forum. I hear you : what question? Well ... wait some days for the mother of all threads: "Total control in collections on a per Item basis" may the Force (the dark option) be with you (and me) best, Peter…; Added by peter fotiadis at 8:10am on December 14, 2014

Comment on: Topic 'High Performance Laptop': a machine that is light and very sturdy. I have taken my Macbook Pro all around the world, carry it with me every day, even dropped it a few times and its still totally fine. Its thin and light. 2) You get some actual support for your hardware even a few years down the line. My Macbook Pro is from 2012 and I can still walk in to any Apple Store and get help with it, which I have done many, many times in different places around the world - I never had to show a receipt or was charged any money for help. There is no PC/Laptop manufacturer in the world with anything close to that, because companies like Asus, Dell, etc. bring out dozens of new versions of laptops every year, so its much harder to service them after a few years. 3) This is the most important one, which usually people forget when they say that Macbooks are overpriced: Resale Value. If you have ever tried to sell an old PC/Laptop (I have a few times), you will know how little value they have even after just 2-3 years. Macbooks retain their value very well and even after 4 years you can still get 50% of your original price. 4) Of course you can install Windows on it and it runs perfectly. I have MacOS and Windows on it and both run absolutely fine. On the Windows side I have Rhino+GH, Maya and a few others. Having Windows is good, because some software still only runs on Windows (looking at you, 3DSMax!). Most other software also runs on MacOS. In the interest of sanity it is great to have an alternative to Windows for all the day to day stuff, like Mail, Calender, Photos, Presentations, etc. that just always works. 5) As for performance: Yes, Macbook Pros dont necessarily have the latest and greatest in graphics cards (the rest is on par with PC laptops), but unless you want to play games you will not need it. VRay RT can do GPU rendering, but you wont get great performance from a Notebook GPU anyways and it doesnt make sense to do rendering on a laptop (especially since you have a workstation). You could get one of the older Macbook Pro Retina Late 2013 or Mid 2014 models with the GTX750M by Nvidia, which will be usable to render using VRay RT, but of course not huge performance. Better to invest in a good used graphics card for your workstation like an Nvdia GTX980ti, which is the best value for money for GPU rendering right now (lots of used ones available). So at least consider also getting a Macbook Pro. You can buy refurbished models (depending where you are) and they are like new, but a lot cheaper or even get an older one thats used. It will be a worthwile investment. Take it from someone who has used dozens of PCs and Macs in my lifetime and have to do the IT support here at work (where we also use both). I still have my Macbook Pro Retina from 2012 and its still running perfectly, super fast, and I can use Rhino and GH for huge files, do GPU Rendering with Octane Render and all sorts of other heavy computing stuff. Hope that helps.…; Added by Armin Seltz at 11:12am on September 19, 2016
