Heating & cooling
Maintain an electric furnace
Electric furnaces avoid combustion concerns, but airflow, electrical controls, heating elements and blower performance still need routine care.
Recommended timingFilter monthly; professional service yearly
What to do
- Check the air filter monthly and clean or replace it when dirty; do not exceed the equipment manufacturer's maximum filter resistance.
- Keep returns, registers and the furnace area clear of storage and dust.
- Schedule preseason service for blower cleaning, electrical inspection, heating-element testing, controls and airflow.
- Record the filter size and service history.
Internal furnace electrical work requires a qualified HVAC technician or electrician.
