High-Efficiency Furnace
High-Efficiency Furnace Installation in Maine
Upgrading to a high-efficiency furnace (95% AFUE or higher) is one of the best ways to reduce heating costs if you're staying with a gas or propane system. RG Mechanical installs 95–98% AFUE furnaces throughout Central Maine — providing accurate sizing and proper two-stage or modulating operation for maximum comfort and savings.

95–98% AFUE models convert nearly all fuel to heat
Modulating and two-stage operation for precise temperature control
Quieter operation than older single-stage models
Lower fuel bills compared to standard 80% AFUE units
PVC venting — no metal flue needed for 90%+ efficiency units
May qualify for utility rebates in your area
Frequently Asked Questions
What AFUE rating should I look for in a furnace?
Compare AFUE with the home's heating load, fuel rates, venting requirements, equipment cost, installation changes, and expected use. A higher rating can reduce fuel use, but it does not guarantee a fixed payback.
What's the difference between a two-stage and modulating furnace?
A two-stage furnace runs at low or high capacity; a modulating furnace adjusts output in small increments for maximum comfort and efficiency. Modulating is the premium option.
Can I install a high-efficiency furnace in a home with an older chimney?
High-efficiency condensing furnaces (90%+ AFUE) vent through PVC pipe, not a chimney — which is actually simpler and eliminates chimney maintenance. We handle all venting during installation.
Will a high-efficiency furnace qualify for any rebates?
Possibly — utility and manufacturer rebates vary. We'll advise on available incentives at your estimate.
