Five reasons to have a heater checked

A change in heating can be a reason to arrange service. Age or one symptom alone does not tell you whether a system needs replacement.

Changes worth describing

  • Uneven heating: note which rooms change and when.
  • Unusual noise or an odor: describe it without opening the equipment.
  • A higher bill: compare rates, weather, settings, and usage as well as equipment condition.
  • Weak airflow or repeated starts and stops: note how the system behaves.
  • Repeated faults or an aging system: bring the service history so a technician can compare options.

Do not dismiss smoke or a persistent burning odor as normal seasonal dust. Stop using equipment that appears unsafe and seek appropriate help. If you smell gas, leave the area and call 911 from a safe place outside. Do not operate switches or try to find the leak. See PG&E’s gas-safety instructions.

Ask for a diagnosis before a replacement decision

A filter problem, airflow issue, control fault, or worn component may need different work. Ask what the technician found, the cost of the proposed repair, and why replacement is being considered. There is no automatic replacement deadline at 12 or 15 years.

A repair diagnosis has a visit charge. Read what a repair visit costs for the first-hour charge, additional time, parts, after-hours rates, and travel charges. The technician explains repair options and costs before you approve repair work.

Plan maintenance separately
