About McDonough Heating & Cooling

Serving New Hampshire & Southern Maine, One Home at a Time

Based in Sanbornville, NH, I’ve built this business around honest work, personal service, and doing the job right the first time. McDonough Heating & Cooling is a one-man operation focused exclusively on mini split heat pump systems—perfect for homes across Wakefield, Wolfeboro, Rochester Ossipee, Conway, and towns throughout southern New Hampshire and southern Maine. If you want a clean, efficient install from someone who answers the phone and shows up, I’m your guy.

MY CORE VALUES

Doing the Job right- That's the Standard

Honest, Local Service

I live in the same region I work—so my reputation matters. No gimmicks or games.

Top-Notch Craftsmanship

Every system I install reflects years of experience and a focus on doing it right, not rushing through it.


Respect for Your Time

I won’t waste yours. If I say I’ll be there, I will. If I can’t, I’ll let you know.
