One point of contact
You nominate who we speak to — you, a household manager, a designer or a general contractor — and everything goes through them. Nobody on our crew knocks on a door to ask a question.

Estates & association properties
On a large or governed property, almost everything that goes wrong is a coordination failure rather than a technical one. This page is about how we prevent that, because it is the part that is actually difficult.
One
A large house is not one problem
The most common failure on a large property is a system that was sized by adding up the square footage. It produces equipment that is too big for most of the house and not big enough for the part that actually needed attention.
Consider an ordinary coastal plan: a double-height room with a west glass wall, a primary suite on the cool north side, a guest wing used a few weeks a year, a room above a garage that bakes, and a kitchen with a commercial range. Five thermal problems with almost nothing in common.
One thermostat cannot describe five different rooms, and no amount of capacity makes it able to.
- What we calculate
- Load for each room individually — orientation, glazing, shading, insulation, ceiling volume, internal gains and how the room is actually used.
- What that produces
- A layout, not a model numberHow many systems, where each air handler sits, which rooms group together, and where the zoning boundaries fall.
- What we will say
- Sometimes the answer is fewer systems than you expected, or that shading one elevation would do more than upsizing anything. We would rather quote the smaller job and be right.
Two
Somebody else has a say
Associations, architectural review committees and coastal overlays govern a surprising amount of a mechanical project. Finding that out after the equipment has been ordered is how a straightforward job becomes an expensive one.
- What is usually governed
- Where equipment may sit and how close to a boundary. How it must be screened, and in what material. A maximum sound level, often measured at a neighbour's line. Permitted working hours and days. Roof access. Whether a contractor may touch a common element at all.
- What we do first
- Read the documentsBefore designing, not after. If the CC&Rs make a proposal impossible, that is a thing to discover at the kitchen table.
- Submittal
- We prepare what the committee needs — location drawings, equipment data, sound ratings, screening detail — and submit it as part of the proposal rather than as an afterthought.
- When a rule is a problem
- We say so plainlyScreening that meets an aesthetic requirement can strangle airflow and shorten equipment life. Where those two pull against each other we set out the trade-off rather than quietly accepting the worse outcome.
Three
Towers, gated communities and access
In a managed building the logistics are the project. Equipment has to be booked into a service lift, the loading dock has an hour, protection has to be laid in a shared corridor, and the old unit has to leave the same way the new one came in.
- Certificates of insurance issued to the association and the management company, in advance
- Service lift and loading dock booked, with the window confirmed in writing
- Corridor and lift protection laid and removed the same day
- Gate lists, badges and escort arrangements handled before the first visit
- Working hours respected, including quiet hours that start earlier than you think
- Old equipment removed from site, not left on a terrace for collection
None of this is technically difficult. All of it is why projects overrun when nobody owns it.
Four
Living in the house while we work in it
Most of these projects happen in occupied homes. That is a scheduling discipline, not a courtesy.
A room at a time
Where the work allows it, the house is taken in sections so that the parts you are using stay usable. It is slower and it is almost always worth it.
Never leaving it worse
No system is shut down at the end of a day without the house still being habitable. If a stage cannot be finished, it does not start.
Cleaned daily
At the end of every day, not at the end of the job. Protection stays down between days; debris does not.
Photographed throughout
Before, during and after, along the whole route. It protects you and it protects us, and it ends arguments about a mark on a stair nosing.
Quiet
Radios off. Phone calls taken outside. It sounds trivial; it is the single thing clients mention most often afterwards.
Five
What you are left with
A project of this size should end with a document, not a handshake. Whoever owns the property in ten years should be able to understand what is installed and why.
- Asset schedule
- Every unit located, tagged and recorded — make, model, serial, capacity, refrigerant, filter sizes and which zone it serves. Plain format, yours to keep.
- Commissioning data
- Measured, not assertedAirflow at each register and return, temperature splits, charge verification and static pressure, recorded at handover.
- Balance report
- The written result of the air balance, which is what you would want in hand if a room is ever disputed later.
- Compliance file
- Closed permit, Title 24 documentation, association approval correspondence and equipment warranty registration, in one place.
- A walk-through
- Of the controls, the filter locations and sizes, the isolation points, and what you should expect to have done and when.
A note on scope
What we are not
We are a mechanical contractor, not a general contractor. On a project that involves structure, plaster, stone or cabinetry we work alongside those trades rather than pretending to manage them.
We are also not a 24-hour service organisation. On an occupied estate the right protection against an overnight failure is a system designed so that one failure does not take the whole house out — which is one of the arguments for multiple systems rather than one very large one.
Begin with a walk of the property
Nothing is priced at that stage, and you keep whatever we work out.
