A gas furnace lasts 15 to 20 years. Past that, the questions are efficiency and reliability: an old 80% unit burns real money every winter compared to a modern high-efficiency one, and the repair-versus-replace math changes fast once the heat exchanger is in question.
Not every no-heat call is a new furnace. A failed ignitor, a bad blower motor, or a clogged filter choking airflow are repairs, and cheap ones. You get told which situation you are in before anything is sold.
Describe what you are seeing. Most problems get narrowed down over the phone before anyone drives anywhere.
You hear what failed, what it takes to fix, and what it costs — before the work starts, not after.
The repair gets done and you get told why it happened, so you know whether to expect it again.
