Buffalo Air Conditioning and Heating Services

Emerald Heating & Cooling has been serving Buffalo and Western New York homeowners since 2000. Founded by Marty and Carrie Sheehan, we’ve spent over two decades building our reputation on honest work, knowledgeable technicians, and the kind of service that keeps customers coming back—and sending their friends and family our way.

Buffalo homeowners can count on Emerald for heating, cooling, and indoor air quality services—repairs, maintenance, replacements, and system upgrades. Our licensed technicians handle complete home comfort needs from start to finish, and we always take the time to make sure you understand what’s being done and why.

We show up on time, give it to you straight, and don’t push you toward anything you don’t need. We take the time to educate our customers, present options honestly, and let you make the call. Our growth has always been built on referrals—and that only happens when people are genuinely happy with the work.
