Commercial HVAC across Brazoria and south Harris
Retail units, restaurants, clinics, offices 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 permanently.
| 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, not estimated. |
| Real age | Decoded from the serial number, which is routinely a decade from what anybody believes. |
| Electrical resilience | Whether there is surge protection, what the measured voltage and start current are, and how the unit is secured. On this coast that belongs on the asset list and almost nobody puts it there. |
| Condensate | Pan, trap, drain, secondary pan and float switch — the most common cause of a summer shutdown and of a stained ceiling. |
| Consequence | What stops trading when it stops. A stockroom and a walk-in do not get the same priority. |
Planned maintenance
Two visits a year, fixed content, readings written down, 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, economiser, and the condensate pan, trap, drain and float switch.
- Electrical: capacitor tested under load, contactor inspected, amp draw and voltage compared with the plate.
Before heating
- Combustion tested with an analyser and the readings recorded per unit.
- 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 — invisible and expensive for a whole season.
- Controls read back against your actual trading hours, including anything lost in an outage.
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, storms 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 building into depression, and then it pulls at every flue in it.
In this climate it also drags humid outside air in through every gap in the envelope all day, which is a cooling and a moisture load as well as a safety problem.
Before storm season
Units secured to their curbs, surge protection fitted, condensate paths clear, and a written note of what has to be switched off and in what order if an outage is coming. The habit is worth more than the hardware, and it only works if it is agreed in advance.
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.
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.
