Last week we asked what has the biggest impact on a furnace's long-term performance.
While all of these factors matter, the answer is often furnace design. The quality of insulation, heating element placement, airflow, structural construction, and thermal efficiency all influence how well a furnace performs over time.
A well-designed furnace can provide more consistent results, require less maintenance, and maintain temperature uniformity for years.
