High-Efficiency Furnaces
Still on gas? We'll service it. And give you the honest picture.
We install and service high-efficiency gas furnaces for homeowners who aren't ready to go electric yet—and we'll tell you plainly if a heat pump would serve you better long-term.
What makes our furnaces efficient
95–98% efficiency. No wasted combustion, no compromises.
Up to 98% of fuel energy converts to heat, not lost up the flue
Variable-speed blowers adjust fan speed to match heating demand, saving 20–30% on blower energy
Modulating burners act like a dimmer switch—precise output, not fully on or fully off
Condensing technology captures latent heat in exhaust gas (that's how they hit 98% AFUE)
Electronic ignition—no standing pilot light burning gas around the clock
Quiet operation, day and night—modern furnaces are significantly quieter than older units
Our furnace services
Installation, repair, and honest replacement planning.
New installation
Repair & maintenance
Replacement planning
We'll specify the right size using Manual J analysis, and recommend the best efficiency level for your budget. Our professional installation includes full performance testing as well.
Whether your furnace is brand new or 15 years old, we keep it running smoothly. Seasonal tune-ups catch problems before they become emergencies. We service all brands and models.
Furnace getting old? We assess its condition, explain your options—repair, replace with gas, or switch to a heat pump—and help you decide what makes sense for your home and timeline.
Premium features
What separates a modern high-efficiency furnace from a basic replacement.
Variable-speed blower — The fan adjusts its speed based on demand, running slowly on mild days and at full speed on the coldest nights. This saves 20–30% on blower energy compared to single-speed units and provides noticeably more even, comfortable heat distribution.
Modulating burner — Instead of fully on or fully off, the burner adjusts its output to match heating demand. Less temperature overshoot, better comfort, lower energy waste. The best furnaces modulate from 40% to 100% capacity continuously.
Condensing technology — The most efficient furnaces extract so much heat that the exhaust actually condenses; that's how they achieve 95–98% AFUE. The technology is mature, reliable, and worth the investment over a standard 80% unit.
Annual maintenance — A furnace is a complex machine. A fall tune-up before heating season catches small problems before they become midnight emergencies. We recommend annual service for every furnace we install or service.
The honest truth
We service furnaces. We'll also tell you when a heat pump makes more sense.
We're not going to oversell electrification. Furnaces are still the right answer for some homes and some budgets. But we're going to give you the full picture so you can make the decision that's right for you.
A furnace makes sense if…
A heat pump makes more sense if…
- Your home is poorly insulated and needs major envelope work before a heat pump would perform well
- You want the lowest upfront cost and plan to sell within a few years
- You already have ductwork in good condition
- You prefer not to go electric yet but want meaningful efficiency improvements now
- You're planning to stay in the home long-term
- You want lower operating costs over 15–25 years
- You're interested in pairing with solar or home batteries
- You want heating, cooling, and potentially hot water from one electric system
- ComEd rebates can make the cost competitive
