Is This You?

Is Your Furnace Costing You More Than It Should?

Furnaces over 15–20 years old with AFUE ratings below 80% are burning money every month. Modern high-efficiency systems run at 96% AFUE — meaning 96 cents of every fuel dollar goes to heating your home. If your system is aging, the math almost always favors replacement.

FAQs

Common Questions

Don't see your question here? Call us — we're happy to talk through your situation before you commit to anything.

Call Us
What AFUE rating should I choose?
For most CT and NY homes, 96% AFUE two-stage is the sweet spot. The fuel savings versus an 80% unit typically justify the price difference within 4–6 years. We'll run the actual payback math with you.
What's the difference between single-stage and two-stage?
Single-stage runs at 100% or off. Two-stage runs at ~65% capacity most of the time — quieter, more even heat distribution, better humidity control, and lower monthly bills. We recommend two-stage for most homes.
Does high-efficiency mean a different venting setup?
Yes. High-efficiency furnaces (90%+) vent through PVC pipe rather than a metal flue. The new vent typically exits through a side wall. We handle all of this as part of the installation.
How long does furnace installation take?
A standard furnace replacement takes 4–6 hours. New installations with significant ductwork or gas line work may take a full day. We'll tell you before we start.
Can you install a furnace in a finished basement or tight space?
Yes — we install in crawl spaces, finished basements, utility closets, and attics. If access is tight, we'll tell you upfront and plan accordingly.
