Find out a broken AC is just a bad thermostat with Grok and Gemini

When their AC stopped working and none of half a dozen companies could come before Friday, a poster asked Grok and Gemini. The poster says they correctly diagnosed a broken thermostat, probably saving hundreds of dollars and 2 days without AC.

Turn a spring-cleaning checklist into a doable 1-hour-a-day plan with ChatGPT

Tom's Guide's Kaycee Hill asked ChatGPT for a complete spring-cleaning checklist for a one-bedroom apartment and got room-by-room sections including easy-to-miss tasks. They then asked it to split the plan into 5 days with 1 hour of cleaning per day; it saved heavier jobs like deep-cleaning the bathroom for the weekend and put quick wins on weekdays. They say they followed the plan and, for once, finished.

Repair a chewed garden hose with Grok's measuring tips

After squirrels chewed through their garden hose, a poster described the problem to Grok. The poster says it explained how to measure the hose's inside diameter and what the standard hose-fitting repair looks like, and the fix was a piece of cake.

Narrow down an intermittent furnace problem before the HVAC visit with Grok

With their furnace acting up intermittently again, a poster ran all the symptoms and everything they'd tried through Grok. They say it walked them through the most likely issues and narrowed them down a lot; even if they couldn't fix it themselves, it armed them with information to cut troubleshooting time so the HVAC company would come prepared.

Track a dishwasher leak to a busted drain hose with ChatGPT (a pro finished the job)

When a dishwasher leak came through their basement ceiling, a homeowner shared photos with ChatGPT and, over a few back-and-forths, narrowed it to a busted drain hose and a worn insulation piece. It found the right parts for their model with a purchase link and walked them through the fix. On the next cycle another puddle appeared because they hadn't clamped the hose far enough, and they called a professional; they say AI got them '99% there'.

Check whether a noisy dishwasher is failing from a recording with Claude

A Hacker News commenter noticed a loud dishwasher at an old apartment and, unsure whether to call a technician, recorded the noise, screenshotted a spectrogram (a picture of the sound) from an app, took photos and gave them to Claude. The commenter says it matched frequencies to the machine's components and concluded it was operating normally, with the pump just louder from age and wear. A reply asked how they could know Claude was right without verifying.

Use Gemini Live's camera to troubleshoot a modem or appliance

Google's guide to household chores with Gemini suggests pointing Gemini Live's camera at a problem, for example asking 'What does this blinking light on the modem mean?', to get step-by-step guidance on setting up toys, caring for a car or repairing appliances. It also suggests scanning fridge shelves for leftover-based meal ideas and uploading receipt photos to track spending. It offers prompts only and doesn't report results.

Troubleshoot a misbehaving espresso machine with Grok

An X user gives Grok a shout-out for helping them fix their HP printer and then, the 'biggest challenge of all', their Breville espresso machine, which they say now works better than it has in years.

Get a furnace running until the repair visit with Gemini and a video

With no repair appointment available for 2 days over the 2025 holidays, a Hacker News commenter filmed the furnace trying to start and gave the videos to Gemini. The commenter says it diagnosed the issue immediately and had them spin a small exhaust fan while the furnace tried to fire; it came on, and repeating that kept it working until the HVAC service arrived.

Diagnose an air conditioner that stopped cooling with ChatGPT and photos

A landlord whose tenant reported the AC wasn't cooling couldn't get a callback from their HVAC company, so they photographed the outdoor compressor panel and used ChatGPT. They say it walked them through what to check using the diagnostic codes they saw and through replacing a $25 capacitor; the service call alone would have cost almost 4x that.

Poster says:$25 part vs a service call almost 4x that

Fix a gas dryer that won't heat with Gemini and a photo

A Hacker News commenter's gas dryer ran but wouldn't heat. Gemini suggested a thermal fuse, pointed it out in a photo of the opened back panel, walked them through testing it, linked the part once they gave the model number, and advised cleaning the vent since poor venting likely blew the fuse. They say after cleaning the exhaust and a $5 fuse the dryer works fine.

Poster says:$5 fuse

Investigate a wet spot on a wall with Gemini Live's camera

A new homeowner writing for All Things Open showed Gemini a wet spot on their bathroom wall through a live camera feed, explained the context and answered its clarifying questions.
