Quick Answer
A dryer with an unresolved fault — particularly a blocked vent, worn seal, or failing heating element — can use significantly more energy and take longer per cycle than a properly repaired one, meaning delayed repairs often cost more over time than fixing the issue promptly.
A dryer taking two cycles to dry a load that should take one is a clear sign that efficiency has already been significantly affected.
It's easy to keep using a dryer that's 'still working', even when it's clearly not performing like it used to. But an inefficient dryer costs more in time and energy every single load — and the fault rarely fixes itself.
Signs Your Dryer Is Running Inefficiently
- Taking noticeably longer to dry the same size load
- Running hotter than usual without drying faster
- Needing a second cycle regularly
- Producing less airflow from the external vent than before
What Delaying Repair Actually Costs
Beyond the extra energy used per cycle, an inefficient dryer puts more strain on its motor and heating components, increasing the risk of a complete failure later. A blocked vent left unresolved also increases fire risk the longer it continues.
How Proper Repair Restores Efficiency
Clearing a blocked vent, replacing a worn seal, or repairing a failing heating element restores the dryer to its original drying time and energy use — the difference is often noticeable from the very next load.

Frequently Asked Questions
How much extra energy does a poorly maintained dryer use?▼
It varies by fault, but a blocked vent or failing element can require significantly more energy and time per load compared to a properly functioning dryer.
Is it worth fixing a dryer that's just 'a bit slower' than usual?▼
Yes — a slower drying time is often an early warning sign of a fault that will worsen, and addressing it early prevents a bigger repair later.
Does a dryer repair pay for itself over time?▼
Often yes, through reduced energy use and avoiding a more expensive failure later — though the main reason to repair promptly is safety and convenience.
How can I tell if my dryer's vent is affecting its efficiency?▼
Check the external vent flap while running — weak or no airflow indicates a blockage that's very likely affecting drying time and energy use.
