Furnace Repair questions
Answers to questions that come up often with this service.
Frequent shut downs can come from a dirty flame sensor, restricted airflow, or a tripped limit switch. A diagnostic visit can identify which one applies.
When the heat exchanger is cracked, or when repairs are adding up on an older unit, replacement is often the more practical choice.
