Commercial HVAC in Thornton and the north metro
Shops, restaurants, professional suites, clinics, warehousing and light industrial. Surveyed first, then maintained against the survey, with a record kept per unit.
The survey comes first
Most premises we are called to cannot say what is on the roof. One visit fixes that permanently.
| Recorded | What it is and why it is on the list |
|---|---|
| Identity | Where each unit is, what it serves, and a number tagged on it, so the next conversation is about RTU 2 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 away from what a tenant believes. |
| Condition | Coils, belts, bearings, economiser, filters, condensate, and the curb the unit sits on. |
| Altitude set-up | Whether the gas appliances were ever set up for 5,300 ft 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 walk-in cooler space do not get the same priority. |
Planned maintenance
Two visits a year on most premises, with fixed content that does not change with who turns up.
Before cooling
Coils cleaned inside and out — in this metro they load with dust and construction fines faster than any manufacturer’s schedule assumes. Charge measured against the conditions and the plate, not topped up on sight. Belts, bearings and mounts. Economiser driven through its range, because a stuck one is silent, invisible and expensive in both directions. Condensate pan, trap and drain.
Before heating
Combustion tested with an analyser and the readings recorded, 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. Controls read against actual trading hours.
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.
Breakdowns
Diagnosed and quoted before parts are ordered. Where the unit is on the survey, the model and refrigerant are already known, which is the difference between one visit and two.
Ventilation, extract and fitting out
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 tell you 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 hours, figures handed over with the asset list.
A unit nobody commissioned never performs, and nobody finds out for two years.
