About

One trade, on somebody else's project.

How we survey and quote, what you can hold us to, and where our scope stops — which on this kind of work matters more than what it includes.

We are a small licensed HVAC contractor on Los Padres Boulevard in Santa Clara, working mainly on accessory dwelling units, garage conversions and small backyard homes across the middle of the valley.

The work is unusual in one respect: most of it happens inside somebody else's programme. There is a designer, a general contractor or an owner-builder, an electrician, an inspector and — usually — a family living in the house at the front of the lot. Being good at this is as much about turning up at the right two moments as it is about the equipment.

So we front-load everything. The load calculation, the equipment selection, the outdoor unit position, the line route and the electrical requirement are issued in writing as early as we are allowed to see the drawings, because every one of those becomes more expensive the later it is settled.

Then we come twice: rough-in before the walls close, commissioning at the end. Both dates are agreed with whoever is running the programme rather than with us.

What you can hold us to

Four commitments.

Short, because a long list is not a commitment.

We calculate, we do not estimate by area

Every quote is based on a load calculated from the building — envelope, glazing, orientation, insulation. If nobody asked you about those, nobody calculated anything.

The electrical requirement is issued in writing, early

In a form your electrician can work from, as soon as the equipment is selected. This is the thing that stalls ADU projects and it is the thing we are most careful about.

The outdoor unit position is agreed before install day

Walked on site, marked, and written on the scope. Not decided by whoever is holding the machine on the day, from whatever positions are left.

The yard goes back every evening

Somebody lives in the house at the front. Materials go back in the van or into the shell, and the path stays walkable.

No electrical panel or subpanel work. We state the requirement; your electrician delivers it. We will not touch a panel and we will not price one.
No general contracting, and no ADU design. We do not draw the unit, we do not run the build and we do not pull the building permit for the structure. We pull the mechanical permit for our scope.
No advice on whether you may build an ADU. Those rules have changed repeatedly and they are specific to your parcel. That is a question for your designer, your city, or both — and we will say so rather than guessing helpfully.
No 24-hour emergency cover. A small shop cannot staff it honestly. The phone is answered from half past seven, and a unit with nothing at all and somebody living in it goes to the front of the day.
No savings percentages, no payback periods, no decibel claims. We give you a load calculation and a position on a drawing, which are facts about your building rather than forecasts about your life.
No pretending a bigger machine fixes an envelope. On a conversion with an uninsulated slab and a weak wall where the door was, we will say so before we quote.

Credentials

Insurance, permits and warranty.

Insurance: General liability and workers' compensationCertificates on request, and sent automatically to any general contractor or owner-builder before we come on site.
Refrigerant: EPA Section 608 certifiedRequired to handle refrigerant legally. Systems are evacuated properly before charging rather than purged, which is the difference between a ductless system that lasts and one that does not.
Permits: Mechanical permit pulled, inspector metFor our scope. The building permit for the unit itself belongs to whoever is running the project.
Warranty: Manufacturer's on the equipment, ours on the labourThe terms are written on the quote in plain sentences. Worth noting: on ductless equipment a manufacturer's warranty often depends on a proper commissioning record, which is one reason we leave the paperwork on site.
