Distribution, flex units, offices, clinics and restaurants
Rooftop plant that has outlived at least one tenant, in buildings where nobody has a drawing of what serves what. That drawing is the first thing we produce.
One sheet per unit, and a folder that survives a change of manager
Every unit located and identified by model and serial number, matched to the area it actually feeds, its measured condition recorded, and dead or abandoned plant marked as dead. On a building that has changed tenants twice, a real share of what is up there will not be connected to anything.
Then the readings that matter commercially: airflow and static pressure, refrigerant charge, economiser operation where one is fitted, filter condition and the pressure drop across it, belt and bearing condition, condensate drainage, and a combustion analysis on gas heat.
The output is a folder in a fixed format, not a note in somebody’s phone. If you have several sites, every folder looks the same, which is the only thing that makes comparing them possible.
Four kinds of premises, four different problems
Distribution and flex units
Heat in a tall building is a stratification problem before it is a capacity problem: the warm air is at the roof and the people are on the floor. Destratification, ventilation, roof treatment and spot cooling at the fixed work positions move the number at head height further than plant would, for a fraction of the cost. We measure both and put the figures side by side.
Offices and medical suites
Usually zoning rather than capacity, and at its worst on a west elevation between three and six on a Texas afternoon. We measure the zones separately at that hour. Clinical spaces get documented filter changes and measured ventilation in a form an inspector will accept; certification to a clinical standard is a specialist engagement and we will say so.
Restaurants and kitchens
Make-up air balanced against hood exhaust, measured rather than assumed. A kitchen out of balance pulls conditioned air from the dining room and the street and makes both impossible. We work on the air. We do not clean hoods, certify fire suppression or touch refrigeration.
Anything that has to survive a freeze
A Texas freeze is not a cold-climate problem, it is a short severe one on equipment that was specified for heat. Heat strips, condensate routes, outdoor pipework and whatever has to keep running when the grid is under strain all get checked before the season rather than during it. That visit is in the autumn and it is the cheapest one we do.
What we do in premises
- Written plant survey
Every unit found, identified, measured and mapped to what it serves, in a fixed format that reads the same at every site.
- Planned maintenance
Scheduled visits, the same readings each time, timed around the building rather than around a calendar.
- Repair and replacement
Repair diagnosed and costed first, with the replacement figure beside it. Replacement planned with curb, opening and crane before anything is ordered.
- Ventilation and destratification
Fans, extraction and make-up air, measured before and after so the change is a number rather than an impression.
- Freeze preparation
An autumn visit on everything that has to keep working through a hard few days.
- Records and handover
A plant list, a maintenance history and a drawing of what serves what, in a form the next manager can use on their first day.
Work we turn down
| We decline | Who it belongs to |
|---|---|
| Sites outside the corridor we can actually serve | Nobody local to them but somebody local to them. We will say so and help you find them rather than take the contract and under-serve it. |
| Central chiller plant and cooling towers | A different discipline with different tickets, and we are not going to learn it on your building. |
| Proprietary building management systems | We will work with the controls in front of us and tell you what a schedule is doing. Programming a manufacturer-locked system belongs to whoever holds the licence. |
| Commercial refrigeration | Walk-ins, display cases and ice machines are adjacent and are not the same trade. |
| Hood cleaning and fire suppression | Separate licensed jobs. We do the air balance around the hood. |
| Clinical certification | Where a space must be certified to a clinical standard we hand it to a specialist rather than sign something we are not qualified to sign. |
Tell us the sites
Where they are, what they are used for, roughly how many units are on each roof, and what a day of downtime costs you at the worst one. 75010 W Hebron Pkwy, Carrollton. Monday to Friday, 7am to 4.30pm.
