CARR vs JCI: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: CARR is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CARR and JCI share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CARR and JCI exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Carrier Global Corporation is a global leader in intelligent climate and energy solutions. After spinning off from United Technologies in 2020, it sold its Fire & Security and Commercial Refrigeration businesses and acquired Viessmann Climate Solutions in 2024 to become a pure-play climate company. Its portfolio spans HVAC, refrigeration and cold chain transportation through brands including Carrier, Viessmann, Toshiba, Automated Logic and Carrier Transicold. The business is organized into four segments: Climate Solutions Americas, Climate Solutions Europe (home to Viessmann), Climate Solutions Asia Pacific Middle East Africa, and Climate Solutions Transportation. Full year 2025 net sales were roughly $22 billion.

Johnson Controls International plc designs, manufactures, installs, and services systems that make commercial and industrial buildings run: heating, ventilation, and air conditioning (HVAC) equipment, building-automation and controls platforms like Metasys, chillers, fire detection and suppression, and security. In August 2025 it completed the sale of its Residential and Light Commercial HVAC business to the Bosch Group in a roughly $8.1 billion transaction (about $6.7 billion net to JCI), reshaping itself into a pure-play commercial-buildings company. Its model leans heavily on long-lived installed equipment plus recurring service and software contracts, which gives it a large book of high-margin aftermarket revenue.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CARR drivers: Data center cooling boom; Heat pumps and electrification of heat.
• JCI drivers: Data-center and AI cooling demand; Pure-play buildings focus after the Bosch sale.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Residential and light commercial HVAC is cyclical and sensitive to housing activity, interest rates and consumer spending, and organic revenue has recently been roughly flat to slightly negative. For JCI, demand for large HVAC and building systems is tied to commercial construction and capital-spending cycles, which can soften with higher interest rates or a slowdown in office, industrial, or data-center building.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CARR if you believe its drivers more; JCI if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CARR and JCI guides.

CARR. As of July 2026 CARR traded near $69 with a market cap around $58 billion and a P/E in the mid-20s to mid-40s depending on whether you use GAAP or adjusted earnings. Q1 2026 beat on revenue and EPS on data center strength, and management reaffirmed roughly $2.80 in full-year adjusted EPS. The valuation embeds expectations that data center and commercial HVAC growth continues while the residential cycle recovers.

JCI. JCI reported second-quarter fiscal 2026 revenue of about $6.1 billion, up roughly 8 percent year over year, with adjusted EPS near $1.19 and a record backlog around $20 billion, and it raised full-year guidance. The stock carries a premium valuation, with a trailing P/E in the low-40s and a forward P/E near 24, reflecting expectations for margin expansion and data-center-driven growth. Figures are approximate and drawn from recent reporting; next results are due late July 2026.

Headline figures (approximate, July 2026): CARR shows revenue (2025) ~$22B, q1 2026 revenue ~$5.3B, adjusted eps (q1 2026) ~$0.57, fy2026 adj. eps guide ~$2.80 midpoint; JCI shows revenue (ttm, continuing ops) ~$24B, q2 fy2026 revenue ~$6.1B (+8% YoY), q2 fy2026 adjusted eps ~$1.19, backlog ~$20B (record).

CARR and JCI are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
