What breaks in Maryland
The fault map follows the fuel map — and each one starts the same way: a call.

Draft & venting helpSteam banging & surging
Venting failures and water-line problems where steam survives on Baltimore’s oldest streets.First move: don't keep resetting it. Call with the symptoms and frequency.
Steam boiler helpPressure loss & cold back rooms
Expansion tanks and weeping joints in renovated rowhouses — plus distribution faults mistaken for boiler faults in deep rowhouse layouts.First move: call, lead with your fuel type and any fault code.
Pressure helpDistribution faults mistaken for boiler faults

Balancing helpOne of these sound familiar? Describe it on the call; triage does the rest.
Call (888) 766-1474Living with steam heat
Baltimore's oldest heating, still working.
A meaningful number of Baltimore rowhouses still heat with steam — one-pipe systems with radiators original to the house, hissing vents, and a boiler that has outlived several owners.
Steam is a different discipline from hot water: the diagnostics are water line, vents, and pressuretrol, and the maintenance is keeping the water clean and the vents working.
The good news: a well-maintained steam system is durable and comfortable, and its radiators are effectively forever. The bad news: neglected steam bangs, surges, and wastes fuel — and well-meaning hot-water techs misdiagnose it.
If your house is on steam, say so on the call; you will get steam questions, not hot-water questions. Our steam vs. hot-water guide explains the differences if you are unsure which system you have — look for a sight glass on the boiler.

Frequently Asked Questions
Straight answers before you call.
Do you serve my Maryland town?
We are rolling out city by city, starting with Baltimore and the metro area. Call with your ZIP code — coverage is checked live on the call, and the service area grows as new cities launch.
My rowhouse has steam heat. Do you handle that?
Yes — steam survives on a meaningful number of Baltimore streets, and steam triage is its own discipline. Describe the water level in the sight glass, any banging, and which radiators are affected when you call.
Does it matter whether my boiler is oil or gas?
If you have oil, mention it up front so the triage switches to burner questions. The other question that matters here is steam vs. hot water.
What should I do if my boiler dies during a cold snap?
If indoor temperatures are falling toward freezing, treat it as urgent — rowhouse pipes in exterior and party walls can freeze within hours. Call the emergency line any time; Ask whether a contractor is available; do not assume a same-night dispatch. While waiting, open cabinet doors under sinks on exterior walls and let taps drip slightly.
