Carrier Infinity 80 Gas Furnace

The Carrier Infinity 80 delivers reliable two-stage heating with variable-speed blower technology at an accessible price point, designed for homeowners prioritizing comfort without the premium efficiency investment.

For Nassau County homes connected to natural gas where ultra-high efficiency isn't the primary concern—such as smaller homes in Levittown or condos in Rockville Centre—the Infinity 80 provides excellent comfort features at a lower acquisition cost. The two-stage gas valve runs at 65% capacity most of the time, reducing temperature swings and noise.

At 80% AFUE, this unit doesn't qualify for PSEG rebates but remains a solid choice when upfront cost is the deciding factor. Parts availability through local distributors like Sid Harvey's and F.W. Webb ensures quick service turnaround.

The 10-year parts warranty and 20-year heat exchanger coverage demonstrate Carrier's confidence in this model's durability.

Best for: Budget-conscious homeowners who want Carrier quality and two-stage comfort without the higher cost of condensing technology.
