Where one plant room serves more than one tenant
Small apartment blocks, mixed-use buildings, churches, halls and the older commercial stock around Pearl Street and Broadway — maintained to a record rather than to a memory.
The first job is writing down what is there
In an older building the plant room is an archive. Pumps from three eras, valves that are no longer connected to anything, a control panel with two dead circuits and one that matters. Nobody can maintain that properly without first recording it.
So we survey, draw a simple schematic, label what is live, and work from that. It is unglamorous and it is the reason the fifth visit costs less than the first.
- Every visitCombustion, safeties, pumps, expansion, water quality where it applies, controls and the zones that actually get used.
- Every reportWritten against each item: what we found, what we changed, what we deliberately left and why.
- Every yearA view of the plant room as a whole, with what is near the end and what to budget.
The usual list, in a shared building
- The top floor is cold and the ground floor is not
Or the reverse. In a building that has been zoned piecemeal, balance is the first thing to establish and the last thing anybody documented.
- One tenant complains and the others do not
Which is useful information rather than a nuisance — it narrows the problem to a zone, a riser or a control rather than the plant.
- The boiler short-cycles
Very common in a building whose load has fallen since the boiler was sized — better windows, better insulation, fewer draughts. It is a controls and sizing question, and it has real answers.
- Hot water is inconsistent
Storage, recirculation and the return loop that somebody valved off during a repair in 2011.
- Nobody knows who is responsible for what
We will tell you what we can see and what condition it is in. Who is contractually responsible for it is a question for the lease, and we will not pretend to answer it.
What we look after
- Small apartment and mixed-use buildingsOne plant room, several tenants, and a heating season that has to go quietly.
- Churches and hallsLarge volumes used intermittently, where the control strategy matters more than the capacity.
- Older commercial stockShops and offices in buildings that were heated long before anybody thought about zoning.
- Community and arts buildingsOccupied spaces where ventilation is not optional and the work has to fit around a programme.
- Buildings with forced air tooRooftop units and splits, serviced on the same schedule and recorded in the same report.
