A chilly morning in Southwest Hills, Millview East, or Redwood is a tough time to discover your heat is out. Maybe the blower is running, but only cool air comes from the vents, or the system refuses to start at all. In those moments, you need emergency heater repair from a company that knows San Marcos, Texas homes and how rapidly Hays County weather can change.

Christianson delivers prompt emergency heater service throughout San Marcos and Greater San Antonio. Our 24-hour emergency service is reserved for urgent situations—no heat during cold conditions, electrical or burning odors, or concerns about safety. For problems that are uncomfortable but not dangerous, we schedule same‑ or next‑day visits during normal hours to restore warmth quickly and cost‑effectively.

Signs you should call for emergency heater repair

  • No warm air from vents: System runs, but air stays cool or just mildly warm
  • Heater will not start: Thermostat is set correctly, but nothing happens at the unit
  • New burning or electrical smells: Sharp odors from the furnace closet or vents
  • Loud banging, screeching, or rattling: Sudden or worsening noises during operation
  • Short cycling: The heater turns on and off every few minutes without heating the home

These warning signs often signal failing motors, control issues, or safety concerns that should be evaluated quickly.

  • Stabilize the situation and address any immediate safety issues
  • Perform detailed diagnostics with modern test equipment
