New furnace, boiler replacement, heat pump installation, or ductless heating — Carey & Walsh Inc. has been designing and installing heating systems across Westchester County since 1944. Free estimates. Manufacturer rebates. Financing available.
Whether you're replacing an aging furnace before winter, upgrading from oil to gas, converting a hot-water baseboard home to a high-efficiency heat pump, or installing ductless heating in an addition, Carey & Walsh has the experience, equipment, and in-house fabrication capability to do the job right. Our licensed technicians have been sizing and installing heating systems across Westchester, Putnam, and Rockland counties for over 80 years — with one standard: get it right the first time.
From gas furnace replacement to full boiler conversions to ductless mini-split installation, we cover every heating system type found in Westchester County homes and businesses. One call — all systems.
New furnace installation or full replacement of an aging unit — we size, select, and install high-efficiency gas and oil furnaces for Westchester homes of all sizes. Manual J load calculations on every job ensure your new system is sized correctly, not just swapped out like-for-like.
Steam and hot-water boiler replacement for Westchester homes. We specialize in the older housing stock common throughout the county — pre-war buildings with steam heat, post-war homes with hot-water baseboard, and everything in between. Full system design, installation, and commissioning.
Modern heat pumps deliver efficient heating and cooling from a single system — and qualify for significant NY rebates and federal tax credits. As a Mitsubishi Electric Diamond Contractor, we're one of the most qualified heat pump installers in Westchester County.
Ductless mini-split systems are the best heating solution for Westchester homes without existing ductwork — including older homes with steam or baseboard heat, finished additions, garage conversions, and sunrooms. As a Mitsubishi Diamond Contractor, we install and configure the full Mitsubishi Electric mini-split lineup.
Commercial heating installation for offices, retail spaces, multi-family buildings, and light industrial facilities throughout Westchester County. We design, install, and commission commercial heating systems built around your building's specific load requirements and budget.
A proper heating installation starts well before anyone sets foot in your mechanical room. Here's exactly what to expect when you hire Carey & Walsh for heating system installation in Westchester.
We visit your home to assess square footage, insulation, existing equipment, fuel type, and your heating goals. For replacement jobs we inspect the current system's condition and note any related issues — ductwork, piping, flue, electrical — that may need addressing.
We perform a Manual J heat load calculation to determine exactly how much heating capacity your home requires. This is the step most contractors skip — we don't. An undersized system can't keep up in a Westchester January. An oversized one short-cycles and wears out faster.
We present system options with transparent pricing, efficiency ratings (AFUE or HSPF), and available rebates. You'll know exactly what you're getting — equipment model, brand, warranty terms, and total installed cost — before signing anything.
Our licensed installers remove your old system and install the new one to manufacturer specifications and NY code requirements. For jobs requiring new or modified ductwork, we fabricate it in our Briarcliff Manor sheet metal shop — same visit when possible.
Once installation is complete, we commission the system — verifying gas pressure, flue operation, airflow, temperature rise, and all controls and safety switches. We don't leave until your new system is running correctly and you're comfortable operating it.
All new installations include manufacturer equipment warranties and our workmanship guarantee. We also help you navigate available NYSERDA incentives and manufacturer rebates — and can set you up on an Energy Savings Agreement to protect your investment going forward.
Installing a new heating system is a significant investment. The quality of the installation determines how efficiently your system runs, how long it lasts, and whether it stays under warranty. Here's why Westchester homeowners and businesses choose Carey & Walsh.
We perform Manual J load calculations on every heating installation. This isn't something most contractors do — they simply replace what was there before, regardless of whether it was ever the right size. Correct sizing means lower bills, longer equipment life, and better comfort throughout your Westchester home.
Our Briarcliff Manor sheet metal shop fabricates custom ductwork to your home's exact specifications. This means shorter lead times, better fit, and sealed connections that actually perform — not off-the-shelf flex duct that leaks and sags within a few years.
For heat pump and ductless heating installation, we hold the highest dealer designation from Mitsubishi Electric — earned through installation volume, technical certification, and customer satisfaction scores. Fewer than 1% of HVAC companies reach Diamond Contractor status.
New heating systems installed in New York may qualify for NYSERDA Clean Heat incentives, manufacturer rebates, and federal Inflation Reduction Act tax credits — particularly heat pumps and high-efficiency systems. We identify available incentives during your estimate and help you capture every dollar. Financing is available on all systems.
