Efficiency choices, explained plainly.

AFUE is the percentage of gas your furnace turns into actual heat. 80% means 80 cents of every dollar becomes warmth. 95% means 95 cents. The higher the number, the lower the gas bill.

Entry
80% AFUE

Reliable, simple, fewer parts to fail. Good for tighter budgets or homes you'll sell in the next few years.

Most common choice
95%+ AFUE

High-efficiency. Typically pays back the upgrade in 5–7 years on Cincinnati gas bills. Sweet spot for most homeowners.

Premium
98% + variable

Variable-speed blower, modulating gas valve. Quieter, more even heating, lowest utility bill. Worth it on long-term homes.

What to expect from the install.

We start with a home visit and proper sizing. Not a guess from your existing unit. An actual Manual J calculation that looks at square footage, insulation, window area, and ductwork. This alone prevents most of the comfort complaints homeowners have with their second furnace.

We quote the whole job with a single all-in number: furnace, labor, permit, disposal, any duct modifications. No line-item "gotchas" on install day.

Install day is typically one day. We pull the permit, install, verify combustion, test airflow and temperature rise, and walk you through the new thermostat. We clean up. Our 10-year workmanship warranty starts the moment we leave.

What installation customers say.

“We first chose Sycamore because we are supporters of local, small businesses. What has kept us coming back was not only Aaron’s knowledge of his trade, but his level of professionalism, integrity, and responsiveness. Our A/C stopped working, so it had to be replaced. In doing my due diligence I contacted a competitor. Their price was staggeringly higher. I’m a realtor and have dealt with many HVAC contractors, and in 16 years, NONE can compare! My only regret, I can only give him five stars.”

“Last year they saved me another year on a 32 year old system when another company wanted to sell me a new system. When my old system finally bit the dust last weekend, Aaron fit me in his schedule and he and CJ put me in a beautiful new system at almost half the cost the other company wanted to sell me. I am a very happy customer in a very comfortable home tonight.”
Jeff Taylor
“Our old HVAC system broke over the weekend. I booked an appointment online and Aaron confirmed my schedule. Nathan assessed our system and recommended a couple of options. Within a day, they replaced our Air Handler and I can confirm that we have a working HVAC again. Their quote is very competitive and top-notch service.”

Furnace installation FAQ.

How long does a furnace installation take?

Most replacements are a single day. If we're also replacing the AC coil or making ductwork modifications, plan for two days. We'll tell you exactly what to expect before the install.

What size furnace do I need?

Depends on your square footage, insulation, ductwork, and climate. We do a proper heat-loss calculation, not a rule-of-thumb guess. An oversized furnace cycles too much and wastes fuel. An undersized one runs constantly and can't keep up in a cold snap.

What efficiency level is worth it?

In Cincinnati winters, high-efficiency (95%+ AFUE) makes financial sense on most replacements — the extra gas savings typically pay the upgrade back in 5 to 7 years. 80% AFUE is fine for secondary spaces or short-term homes. We help you pick based on your actual situation.

Is the 10-year warranty in addition to the manufacturer's?

Yes. Lennox covers the equipment itself — usually 10 years on parts and separately on the heat exchanger. Our 10-year warranty covers the installation work: if something fails because of how we installed it, we come back and fix it at no charge.
