Commercial HVAC across Onondaga County
Shops along Erie Boulevard, restaurants, salons, professional suites, clinics and light industrial. Surveyed before anything is scheduled, then maintained against the survey.
The survey
Most premises we are called to cannot say what is on the roof. One visit fixes that, and everything else depends on it.
One page per unit
| 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 rather than estimated. |
| Real age | Decoded from the serial number. It is the field this whole business argues about, and it takes a minute. |
| Refrigerant | Recorded explicitly. An R-22 system changes the arithmetic on every future repair, and you should know before the repair rather than during it. |
| Condition | Coils, belts, bearings, economiser, filters, condensate, and the curb the unit sits on. |
| 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 means nobody can tell you a nine-year-old unit is twenty — which is the commercial version of the argument the whole site is built on.
Planned maintenance
Two visits a year on most premises, with fixed content and a sheet per unit afterwards.
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 and the plate, never topped up on sight.
- Belts, bearings and mounts, and the economiser driven through its full range.
- Condensate pan, trap and drain — which in a shared building becomes somebody else’s ceiling.
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.
- Condensate lines through cold space checked before the season that freezes them.
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.
Extract, ventilation and fit-out
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.
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.
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
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.
