Commercial HVAC across Collin County
Retail units, restaurants, salons, professional suites, clinics and light industrial. Surveyed before anything is scheduled, then maintained against the survey.
One page per unit, before any schedule
Most premises we are called to cannot say what is on the roof. One visit fixes that permanently, and everything else depends on it.
| 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 a numbered unit 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 in the building believes. |
| Condition | Coils, belts, bearings, economiser, filters, condensate, and the curb the unit sits on. |
| Duct condition | Where the runs go and what they are losing. In this market that is a bigger number than anything on the roof, and it almost never appears on an asset list. |
| 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.
Two visits a year, fixed content
And in this climate the cooling visit is the one that earns its place several times over.
Before cooling
- Coils cleaned inside and out; a condenser that looks clean from above can be packed solid on the inner face.
- Charge measured against the conditions on the day and the plate figure, never topped up on sight.
- Belts, bearings and mounts, and the economiser driven through its full range.
- Condensate pan, trap, drain and float switch — the most common cause of a mid-summer shutdown here.
- Electrical: capacitor tested under load, contactor inspected, amp draw compared with the plate.
Before heating
- Combustion tested with an analyser and the readings recorded per unit, so the file shows a trend.
- Flue and combustion air checked, including anything a tenant has added since.
- Heat exchanger inspected; a failed one means shut off and tagged, not patched.
- Heat pump auxiliary heat checked — a fault there is invisible and expensive for a whole winter.
- Controls read against how the premises actually trades, including holiday schedules.
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.
Kitchens, salons 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.
In this heat it does something else as well: it drags 100-degree outside air in through every gap in the envelope, all day, which is a cooling load as well as a safety problem.
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.
Fitting out a unit
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.
Before you sign a lease we will look at the plant and tell you its real age from the serial number and its actual condition.
