Common reasons your heater stops working include thermostat settings or dead batteries, a tripped breaker, a dirty air filter, or a safety lockout. Gas furnaces often fail from a dirty flame sensor or bad igniter. Heat pumps may stop due to iced outdoor coils or low refrigerant. Blocked vents or a full condensate pan can also shut systems down. We offer 24/7 emergency heating repair and same-day service in Charleston and nearby.
Quick checks:
- Set thermostat to Heat and raise the setpoint.
- Check the breaker and furnace switch.
- Replace a dirty air filter.

There isn’t a one-size price for a new furnace for a 2,000 sq ft home. Final cost depends on system type (gas or electric), efficiency rating, ductwork condition, thermostat choice, and any indoor air quality add-ons. We confirm pricing after an on-site assessment and proper sizing. Current promos can lower your total: $500 OFF Furnace Installation or $1,000 Off New HVAC Install. Same-day options are available in Charleston and nearby cities.
Quick steps:
- Schedule an in-home evaluation.
- Review options and transparent pricing.
- Apply any active installation discounts.
