Donnelly Mechanical | Commercial HVAC Contractor

Leaving Manhattan last night was absolute chaos! It took us over an hour just to get out of the city – every street was gridlocked no matter which way we turned. Thankfully, I ended up behind a Donnelly Mechanical truck and had a gut feeling this guy knew the way out. From Hell’s Kitchen to the Holland Tunnel, he led the way, and we owe him big time! Thank you, unsung hero in the Donnelly truck – you have no idea how awesome you were. Sincerely, The People in the Volvo Behind You Last Night.

One of their drivers almost hit my kids while we were crossing the street and then got out and threatened us because we had the right of way while crossing. When we called the company they fairly unresponsive.

Best air conditioning company locally.

Tried to get a estimate from them. The project manager kept saying he's going to come back with a ladder. He was unresponsive Wasted 3 weeks and then said we aren't going to bid. Very unprofessional

Very nice atmosphere professional & helpful. I recommend this shop to do a great job. I was happy with my service. They put in my radiator in my Jeep Wrangler.
