Ask About OffersA proper AC installation isn't just about dropping in equipment — it's about sizing, design, and workmanship. Here's what you can expect when you hire Carey & Walsh.
We visit your home to assess square footage, insulation, existing ductwork, and your comfort goals. We perform Manual J load calculations to determine the correct system size — no guesswork, no oversizing.
We present equipment options from leading brands with transparent pricing, SEER ratings, and available rebates. You'll know exactly what you're getting — and what it will cost — before any work begins.
Our licensed technicians install your system with care — including any ductwork from our in-house sheet metal fabrication shop. We follow manufacturer specs and NY code requirements on every job.
Before we leave, we run a full system test, verify airflow and refrigerant charge, and walk you through the controls. You'll know how to get the most out of your new system from day one.
All new installations come with manufacturer equipment warranties and our workmanship guarantee. We're also available for ongoing maintenance to protect your investment and keep your system running efficiently for years.
Unlike most Westchester HVAC contractors, we operate our own sheet metal shop in Briarcliff Manor. Custom ductwork is fabricated to your home's exact specs — faster turnaround, better fit, tighter seals.
When you invest in a new cooling system, the quality of the installation matters as much as the equipment. Here's what sets us apart from other HVAC companies in Westchester County.
We hold the highest dealer designation from Mitsubishi Electric — earned through installation volume, technical training, and customer satisfaction scores. Fewer than 1% of HVAC companies achieve Diamond Contractor status. For ductless mini-split installation in Westchester, there's no higher-qualified team.
We fabricate custom ductwork at our own Briarcliff Manor shop — not outsourced, not off-the-shelf. That means faster lead times, precise fits, and tighter seals that improve system efficiency and reduce energy loss.
Oversized AC systems short-cycle, fail faster, and leave your home humid. Undersized units run constantly and can't keep up in a Westchester July. We perform Manual J load calculations on every installation to get the sizing exactly right.
We've been installing HVAC systems in Westchester homes since 1944. We know the housing stock, the climate, and the installation challenges that come with older New York homes — from pre-war construction to newer developments in Cortlandt and Yorktown Heights.

"We had central AC installed last spring and the whole process couldn't have been smoother. They sized the system correctly, the installation was clean, and the house has never been cooler. Best contractor we've ever hired."
"We had a Mitsubishi ductless system installed for our addition. The installation crew was meticulous — they left the house cleaner than they found it. The system is whisper-quiet and our energy bills dropped noticeably. Highly recommend."
"Carey & Walsh replaced our old AC system with a high-efficiency unit and the difference is remarkable. They explained everything upfront, there were no surprise charges, and the job was done in one day. Will absolutely use them again."
