The Equipment We Stand Behind

Heating & Cooling
Products for Westchester
Homes and Businesses

The brand on the box matters less than most people think. What determines whether a system runs efficiently for twenty years is whether it was sized correctly, matched properly, and installed by someone who knew what they were doing. That's why we only carry equipment we're willing to put our own name behind — and why we install every unit ourselves.

  • ✔ Gas, oil, and electric furnaces — high-efficiency models available
  • ✔ Central air conditioning systems for homes of every size
  • ✔ Mitsubishi ductless systems — we're a Diamond Contractor
  • ✔ Heat pumps, including cold-climate models built for NY winters
  • ✔ Steam and hot-water boilers for older Westchester housing stock
  • ✔ Indoor air quality equipment and programmable thermostats

What We Carry

Every System Type,
One Contractor

Whatever your home or building runs on now — and whatever makes sense to replace it with — we supply, install, and service it. All ENERGY STAR certified options available.

🔥
Furnaces
Gas · Oil · Electric

Forced-air furnaces in gas, oil, and electric — including high-efficiency condensing models that extract heat from exhaust gases most older furnaces send straight up the flue. We size every one with a load calculation rather than matching whatever was there before.

  • ✔ High-efficiency condensing gas furnaces
  • ✔ Oil furnaces and oil-to-gas conversions
  • ✔ Electric furnaces and air handlers
  • ✔ York and all other major manufacturers
  • ✔ Custom ductwork from our own sheet metal shop
❄️
Air Conditioners
Central cooling · ENERGY STAR rated

Central air conditioning matched to your home's actual cooling load. An oversized unit cools fast and shuts off before it removes humidity, which is why some houses feel cold and clammy at the same time. Correct sizing solves that.

  • ✔ Central split-system air conditioners
  • ✔ ENERGY STAR certified high-efficiency models
  • ✔ York and all other major manufacturers
  • ✔ Matched coil and condenser pairings
  • ✔ Retrofit options for homes with existing ductwork
🏠
Ductless Systems
Mitsubishi Diamond Contractor

Ductless mini-splits heat and cool without any ductwork at all — the standard answer for older Westchester homes on steam or baseboard heat, additions, sunrooms, attics, and garages. As a Mitsubishi Diamond Contractor we install the full Mitsubishi Electric lineup.

  • ✔ Mitsubishi Electric single-zone and multi-zone systems
  • ✔ Wall-mount, ceiling cassette, and floor-mount indoor units
  • ✔ Heats and cools from one system, year-round
  • ✔ Independent temperature control in every zone
  • ✔ Installs with minimal disruption — no ducts required
🔄
Heat Pumps
Heating & cooling in one system

A heat pump moves heat rather than burning fuel to create it, which is why it delivers more heating energy than the electricity it consumes. Modern cold-climate models are engineered to keep producing heat well below freezing — including through a Westchester January.

  • ✔ Cold-climate heat pumps rated for NY winters
  • ✔ Central ducted systems for homes with existing ductwork
  • ✔ Ductless heat pumps for zone-by-zone control
  • ✔ Qualifies for NY and federal efficiency incentives
  • ✔ One system replaces both furnace and air conditioner
♨️
Boilers
Steam & hot water · Gas & oil

Westchester has a lot of older housing stock, and a lot of it is heated by radiators and baseboard. We supply and install steam and hot-water boilers in gas and oil, including high-efficiency condensing models, and handle the piping and controls that come with them.

  • ✔ Steam boilers — one-pipe and two-pipe systems
  • ✔ Hot-water boilers and hydronic system upgrades
  • ✔ Gas and oil-fired, standard and high-efficiency
  • ✔ Zone valves, circulator pumps, and piping included
  • ✔ Oil-to-gas boiler conversions
💨
Indoor Air Quality
Filtration · Humidity · Controls

Your heating and cooling system moves the air in your home every time it runs — which makes it the most effective place to filter, humidify, and control that air. We install air quality equipment and programmable and Wi-Fi thermostats, including Honeywell.

  • ✔ High-efficiency media filtration and air cleaners
  • ✔ Whole-house humidifiers for dry winter air
  • ✔ UV treatment at the coil
  • ✔ Honeywell programmable and Wi-Fi thermostats
  • ✔ Ventilation and air exchange equipment
Choosing the Right System

How We Help You
Pick the Right Equipment

Buying heating or cooling equipment is not like buying an appliance. What's right for your home depends on the building itself — and that takes a visit, not a phone quote.

01
🏠
We Look at the Building

Square footage, insulation, window count and orientation, ceiling heights, existing ductwork or piping, and what fuel is available. Two houses on the same street can need very different equipment.

02
📐
We Calculate the Load

A Manual J load calculation tells us how much heating and cooling capacity your home actually requires. Most contractors skip this and simply match the old unit's size — even when that size was wrong to begin with.

03
⚖️
We Explain the Trade-Offs

Efficiency ratings — AFUE for furnaces and boilers, SEER2 for cooling, HSPF2 for heat pumps — translate directly into operating cost. Higher-rated equipment costs more upfront and less to run. We'll show you where that line falls for your home.

04
🔧
We Match the System

Equipment has to be matched properly — a condenser to the right coil, a boiler to the right piping and controls. A mismatched pairing never delivers its rated efficiency no matter what the label on the box says.

05
📋
You Get It in Writing

Model numbers, efficiency ratings, warranty terms, what's included, and the total installed price — all in a written proposal before you commit to anything. Estimates are free and there's no obligation attached.

06
🛡️
We Install and Register It

Our own licensed technicians install and commission the system, then register the equipment so your manufacturer warranty is documented and in force. We also flag any rebates or incentives the system qualifies for.

Why Buy From Carey & Walsh

The Installation Matters
More Than the Brand

Every major manufacturer builds good equipment now. What separates a system that runs quietly for twenty years from one that's a service call every season is who sized it, who matched it, and who installed it.

🏆
Mitsubishi Diamond Contractor

The highest dealer designation Mitsubishi Electric awards, earned through installation volume, technical certification, and customer satisfaction. On ductless and heat pump work it also means access to extended warranty coverage most dealers can't offer.

📐
Sized With a Load Calculation

We run Manual J on every installation rather than replacing like for like. An undersized system can't keep up in a Westchester January; an oversized one short-cycles, never dehumidifies properly, and wears out years early.

🏗️
In-House Sheet Metal Fabrication

Our Briarcliff Manor shop builds custom ductwork to your home's exact specifications — better fit, tighter seals, and no waiting on a supplier. It's the difference between a system that performs to spec and one that merely looks good on paper.

👷
Installed by Our Own Technicians

NY-licensed, insured, NATE-certified, and background-checked — and they work for us, not for a subcontractor. The same company that sold you the equipment is the one accountable for how it runs.

💰
Rebates, Incentives & Financing

High-efficiency systems and heat pumps installed in New York may qualify for state incentives, federal tax credits, and manufacturer rebates. We identify what your project qualifies for during the estimate, and financing is available on qualifying equipment.

Not Sure Which System You Need?

That's what the free estimate is for. We'll look at the building, run the numbers, explain the options in plain language, and put a price in writing — with no pressure attached.

What HVAC brands do you carry? ▼
We're a dealer for Mitsubishi Electric, York, and Honeywell. On ductless and heat pump equipment we hold Mitsubishi's Diamond Contractor designation, which is their highest dealer level. We also install and service equipment from every other major manufacturer, so you're never limited to one brand.
Diamond Contractor is the highest dealer designation Mitsubishi Electric awards, earned through installation volume, ongoing technical training and certification, and customer satisfaction scores. For you it means the technicians installing your system are factory-trained on that specific equipment — and that we can offer extended warranty coverage that non-Diamond dealers cannot.
Honestly, brand matters less than most homeowners expect. Every major manufacturer builds reliable equipment at this point, and the differences between them are smaller than the difference between a good installation and a poor one. A mid-tier system sized correctly and installed properly will outperform a premium system that was oversized and rushed. Judge the contractor at least as carefully as the badge on the equipment.
They're efficiency ratings. AFUE measures what percentage of the fuel a furnace or boiler converts into usable heat — a 95% AFUE furnace turns 95% of the gas it burns into heat for your home. SEER2 rates cooling efficiency and HSPF2 rates heat pump heating efficiency; higher numbers mean less electricity for the same output. Higher-rated equipment costs more upfront and less to operate, and we'll show you where that trade-off lands for your home during the estimate.
ENERGY STAR is a certification program run by the U.S. Environmental Protection Agency. Equipment carrying the label meets efficiency standards set above the federal minimum for its category. It's a useful shortcut when comparing models, and ENERGY STAR certified equipment is often what qualifies for utility and state rebate programs.
Yes. We repair and maintain heating and cooling equipment from all major manufacturers regardless of who installed it or where it came from. Taking over service for a system someone else put in is routine work for us, and we'll give you an honest assessment of its condition.
For Westchester homes on steam, hot-water baseboard, or radiant heat with no forced-air ductwork, a ductless mini-split system is usually the cleanest answer — it adds cooling and supplemental heating without opening walls, and it qualifies for New York efficiency incentives. If you'd rather have a ducted system, we can design and fabricate the ductwork in our own shop. We'll walk you through both during the estimate.
Often, yes — particularly on heat pumps and high-efficiency systems. New York State incentive programs, federal tax credits, and manufacturer rebates all change periodically, and eligibility depends on the specific equipment and its efficiency rating. We track what's current and will tell you exactly what your project qualifies for at the time of your estimate.
