Looking for Skilled Steam Contractor - near Berwyn, PA - Install + System Troubleshooting

Hello everyone,

I've been reading The Wall and learning from Dan Holohan's work as I prepare to replace the steam boiler in my three-story home near Berwyn, PA (Main Line area, west of Philadelphia). House is from the early 1900s. I'm hoping this community can point me toward a contractor who truly understands steam.

My System:
Two-pipe steam
Original cast iron radiators throughout
Calculated EDR approximately 860 sq ft

What I Need:
Boiler installation — Looking to install a Peerless 64-07

System troubleshooting — I have some banging in the pipework that I'd like diagnosed and corrected. Likely pipe pitch issues. I want someone who can evaluate the system properly and fix the root cause.

What I'm Looking For in a Contractor:
I'm not chasing the cheapest price — I'm looking for the right person.

Deep steam expertise — Someone who really knows steam and can troubleshoot an old system, not just swap equipment

Experience with old homes — Early 1900s construction has its quirks

A long-term service relationship — I want the contractor who installs it to maintain it for years to come

Fair pricing — I'm prepared to pay for expertise

Does anyone have a recommendation for a steam contractor serving the Berwyn / western Philadelphia suburbs area?

I've done my homework and I'm ready to be a good customer to the right contractor. Just need help finalizing a selection.
Thank you,
Matt
Berwyn, PA
