FAQs

Is 80% AFUE right for my home?
It can be. If winters are mild and budget leads, 80% offers solid comfort at a lower upfront cost. However, for colder areas or the lowest gas use, consider 95–98% AFUE options.

What’s the advantage of two-stage heat with a variable-speed blower?
Two-stage heating often runs on low stage longer, which keeps rooms more even and reduces noise; high stage kicks in for colder weather. The variable-speed blower further smooths airflow and can help summer dehumidification with compatible cooling.

Can I use propane instead of natural gas?
Yes. With an approved LP conversion accessory, this model can run on propane.

What is covered by the warranty?
With timely registration on eligible equipment, choose 10-year parts, 10-year labor (GSHA Services LTD), plus a lifetime heat exchanger limited warranty (registration and jurisdiction rules apply)
