Efficiency
Small maintenance issues can make appliances work harder.
Efficiency is often about airflow, heat transfer, seals, loading and sensible settings—not a hidden “eco hack.”
| Appliance | Issue | Why it matters | Owner action |
|---|---|---|---|
| Refrigerator/freezer | Door seal and unnecessary openings | Warm air adds cooling load and moisture/frost. | Check closure/seal, avoid long-open doors, keep internal vents clear. |
| Refrigerator/freezer | Poor ventilation / dirty accessible condenser area | Heat rejection becomes harder. | Maintain required clearances and owner-serviceable cleaning. |
| Dryer | Restricted lint/vent airflow | Longer dry times and higher temperatures. | Clean lint filter and maintain approved vent path. |
| Washer | Very small/very large loads and unnecessary hot cycles | Can waste water/energy or reduce performance. | Use appropriate programme/load guidance. |
| Dishwasher | Pre-rinsing excessively / partial loads | Can waste hot water and electricity. | Scrape food and use suitable full loads/programmes where manufacturer permits. |
| Oven | Repeated door opening / poor door seal | Heat escapes and recovery takes energy. | Use window/light and address damaged seals. |
| Air conditioner | Dirty filter / blocked airflow | Reduces heat transfer and can extend run time. | Clean/replace user filter on schedule; keep airflow clear. |
Do not chase efficiency at the expense of safety/hygiene: Use temperatures and programmes suitable for the load and follow manufacturer hygiene, food-safety and drying guidance.
