Vented dryers blow ~150 CFM of conditioned air outside — this hidden HVAC cost stacks on top of resistance or gas heat. Heat pump ventless units close the loop.
Laundry & Home Setup
Vented dryers exhaust ~150 CFM — your HVAC re-conditions replacement air in heating or cooling mode.

Practical tips & common mistakes
Ventless still needs airflow
Heat pump dryers need clean condenser filters — blocked airflow mimics resistance heat draw and erases efficiency gains.
Ignoring makeup-air cost
Vented gas dryers look cheap on fuel but punch holes in your building envelope. Include HVAC penalty in cold-climate homes.
Sensor dry beats timed dry
Over-drying wastes energy regardless of heat source. Use moisture sensing cycles to cut runtime 10–20%.
Gas vs electric vented
Gas heat is cheaper per BTU in many regions but still vents conditioned air. Compare total $/yr, not fuel type alone.
