The downsides of a gas dryer include higher upfront cost, installation complexity, gas leak and carbon monoxide risks, and maintenance requirements compared to electric dryers. Gas dryers typically cost 50 to 150 dollars more than comparable electric models upfront, and installation requires a licensed professional to run a gas line, install a shutoff valve, and ensure proper leak testing, which can add 150 to 350 dollars if a gas line is not already present. This makes them unsuitable for all-electric homes or apartments without gas service. Safety is another concern: while very safe when installed correctly, gas dryers have a small risk of gas leaks if connections loosen and a theoretical risk of carbon monoxide production from incomplete combustion if venting is blocked, so they require a carbon monoxide detector nearby and annual inspection of the gas valve, burner, and venting. Maintenance costs can be higher because gas dryers have additional components like igniters, flame sensors, and gas valve solenoid coils that wear out after 5 to 10 years and cost more to replace than a simple electric heating element. Gas dryers also require both a gas line and a 120-volt outlet plus rigid metal venting, limiting placement flexibility. Finally, if natural gas prices rise, operating costs can exceed electric heat pump models.
