Facility HVAC across the north-west metro
Retail, light industrial, professional suites, clinics and warehousing. Surveyed before anything is scheduled, maintained against the survey, and recorded per unit.
The survey
Most buildings we are called to cannot say what serves what. That is the first thing we fix, and it takes one visit.
| Recorded | What it is and why it earns its place |
|---|---|
| Identity | Where each unit is, what it serves, and a tag on it — so the next conversation is about RTU 3 rather than “the one at the back”. |
| Plate data | Make, model, serial, capacity, electrical requirement, refrigerant and factory charge. Copied off the plate, not estimated. |
| Real age | Decoded from the serial number, which is routinely a decade from what anybody believes. |
| Condition | Coils, belts, bearings, economiser, filters, condensate, and the curb the unit sits on. |
| Controls and schedules | What is actually programmed, against how the building actually trades. This is the field that prevents the most call-outs, and it is the one nobody else records. |
| Altitude set-up | Whether the gas appliances were ever set up for this elevation according to their own installation instructions. On premises fitted out quickly, frequently they were not. |
| Consequence | What stops trading when it stops. A stockroom and a treatment room do not get the same priority. |
It changes what you pay
An asset list turns emergencies into scheduled work. When the unit that fails is already recorded, the part is ordered on the first call rather than the second visit.
It changes what you are told
It also stops you paying to replace something nine years old because somebody said twenty — and stops a genuinely finished unit being nursed through another summer at your expense.
Planned maintenance
Two visits a year on most buildings, with fixed content that does not change with who turns up.
Before cooling
- Coils cleaned inside and out. On the Front Range they load with dust and construction fines faster than any manufacturer’s schedule assumes.
- Charge measured against the conditions on the day and the plate figure, never topped up on sight.
- Belts, bearings and mounts.
- Economiser driven through its range. Stuck open in July it is pulling 95°F air in all day; stuck shut in April it is running the compressor on a day when outside air would have done the job for nothing. Neither is audible from inside.
- Condensate pan, trap and drain — the thing that becomes a ceiling stain.
Before heating
- Combustion tested with an analyser and the readings recorded per unit, so the file shows a trend rather than a stack of invoices.
- Flue and combustion air checked, including anything a tenant has added since. A new extract fan can pull a flue backwards in a tight building.
- Heat exchanger inspected; a failed one means shut off and tagged, not patched.
- Schedules and setbacks read and confirmed — including holiday schedules, which is the single most common cause of a Monday-morning call.
- Filter sizes written down so the next set is right without a tape measure.
What lands on your desk
A sheet per unit with the readings on it, a note of what will need doing and roughly when, and a short list of anything that should be done now with a price against it. Not a tick-sheet, and not a sales letter.
Ventilation, extract and make-up air
Kitchens and workshops
Canopies, ducts and fans — and replacing the air you are throwing away. A kitchen extracting hard with no make-up air path pulls the whole building into depression, and then it pulls at every flue in it.
That is the mechanism behind a pilot that will not stay in, a back door that will not open, and a carbon monoxide alarm nobody can explain. It is measurable and it is fixable.
Suites and clinics
Where the complaint is stuffiness rather than temperature we measure outside air actually delivered, the filtration in place, and whether the system short-cycles so hard it never ventilates.
We make no health claims for air cleaning equipment. We will say what a room is getting and what it costs to change it, and leave the clinical judgement to you.
Fit-out and commissioning
Ductwork, diffusers, extract and controls for the layout you are actually building, coordinated with whoever is doing the ceiling rather than after them. Airflows balanced and recorded, controls set to your trading hours, figures handed over with the asset list.
A space nobody commissioned never performs, and nobody finds out for two years.
