Heating service built for a real Buffalo winter.
Buffalo doesn't do "mild." When the lake-effect machine kicks on, your furnace runs 18 hours a day for weeks. That's the load we design and service for — and why our installations outlast most of our competitors' by five years on average.
Most Buffalo furnaces fail at midnight, in February, during a windchill warning.
That's not bad luck — it's physics. A marginal furnace can struggle through autumn and limp through December, then the first sustained sub-zero week pushes it over. The Zenner & Ritter approach: a real load calculation, the right-sized equipment, and a tune-up every fall so the failure happens on our schedule, not yours.

Heating FAQs.
How long does a furnace installation take?
Standard one-for-one replacement: 5–7 hours, same day. Adding a high-efficiency PVC vent or a new condensate pump can extend to a full day. We confirm the timeline before we start.
What's the lifespan of a furnace in Buffalo?
Buffalo's heating season averages 4,500 hours per year — about 25% more than the U.S. average. A well-maintained high-efficiency furnace lasts 18–22 years here. Without annual service, that drops to 12–14.
Is a 96% AFUE furnace worth the extra cost?
Versus an 80% unit, yes — typically a 4–6 year payback in Western New York energy prices. We model the actual NYSEG bill savings before recommending an upgrade.
