Brownstone Heating & Air Conditioning is EPA-certified and insured for work across NYC, so every job — from a single mini split swap to a full system replacement — is protected and code-compliant. We quote honest, upfront pricing before any tools come out, with no surprise add-ons after the fact and 0% financing available on qualifying repairs and installs. Our techs diagnose the root cause and fix it right the first time instead of patching symptoms that come back next week. And because we're a local Brooklyn shop, not a national chain, you get the same crew on follow-ups and a phone that actually gets answered.
Price up front. No hidden fees. Financing on qualifying jobs.
We diagnose the root cause, not just patch symptoms.
Factory-trained, background-checked, fully insured.
If it's not right, we make it right.

"My AC stopped working as a heat wave started. Ben picked up the phone when I called, gave me a realistic assessment of his availability, arrived when he said he would, was straightforward about the cost — and then did a tremendous job."
— Justin V., Park Slope · June 2025
"I called Brownstone for a second opinion after my heat stopped working during deep freeze. The first company wanted to charge a high price to dismantle and clean my system. Ben offered a much better option — for the same price, he installed a brand new furnace and motor."
— Jonathan B., Cobble Hill · February 2026
"Ben has been helping me with my many AC needs for the past few years. He is very reliable, has always found the issue quickly, and has been able to solve it."
