Gas
- Gas Appliance Connections: The Leak Check — The rotten-egg odorant and the smell-it-leave-it rule, the soap-bubble test at fittings, flexible connector rules and the old-connector recall history, and what belongs to the utility versus the plumber.
General
- Appliance Lifespans: Repair or Replace — The realistic lifespan table by appliance, the 50-percent rule and the half-life test, the repairs always worth making versus the parts that are retirement notices, and the efficiency math that tips old machines.
Kitchen
- Dishwasher Not Draining: The Checklist — The drain path from filter to air gap to disposal knockout, worked in order: the standing-water checklist, the new-disposal mistake that stops half of them, and when the pump is actually guilty.
- Garbage Disposal Jams and Resets — The hum-versus-silence diagnosis, the hex-key ritual at the bottom of every disposal, the red reset button, what never goes down one, and the leak locations that decide replacement.
- Range Hoods: Ducted vs. Recirculating — Why kitchen exhaust is an air-quality system, the honest gap between ducted and recirculating hoods, CFM and capture design, the duct rules, and making the best of the ductless case.
- Refrigerator Not Cooling: Coils, Fans, and Airflow — The warm-fridge checklist in order of likelihood: dusted condenser coils, dead condenser and evaporator fans, frosted-over evaporators from failed defrost, blocked vents, and the compressor question.
Laundry
- Dryer Vent Cleaning and the Lint Fire Hazard — Why dryer fires are a lint-and-airflow story: the duct rules from the transition hose to the exterior hood, the cleaning rhythm, the foil-hose and long-run sins, and the takes-two-cycles symptom.
- Washing Machine Won't Drain or Spin: Diagnosis — The drain path from pump filter to standpipe, the coin-trap ritual nobody was told about, lid switches and unbalanced-load logic on the spin side, and the suds and siphon oddities.
Protection
- Water Leak Detectors and Automatic Shutoff Valves — The cheap sensors that catch the floods statistics say are coming: puck detectors and their placement map, smart shutoff valves on the main, flow-sensing systems, and the insurance angle.
Ventilation
- Whole-House Fans vs. Attic Fans — Two fans that get confused constantly: the whole-house fan that cools people with evening air, the powered attic fan that ventilates the attic itself, what each actually does, and where each backfires.
