FIG. 01·Design conditions

This climate is the whole job.

Equipment that would last fifteen years somewhere temperate does not get to here. Everything below is a published condition for this valley, not a claim about us.

Summer design temperature
115°F

the outdoor temperature equipment here has to be sized against

Attic temperature in July
160°F

what an unconditioned Phoenix attic reaches in July, with your ducts in it

Cooling season
7 months

of cooling load, April through October

FIG. 03·The promise

Sized by calculation. Priced before we start.

Most of the efficiency you pay for on the label is decided by the install, not the equipment. Two systems with the same rating can be twenty percent apart once they are in the house.

Load calculation
Manual J

Room by room, every install. It is the step most companies skip.

Commissioning
Measured

Charge, airflow and static pressure, handed to you in writing.

After-hours rate
$0

Same price at midnight in July as at ten on a Tuesday.

Labour guarantee
2 years

Same fault inside two years and we come back free.

FIG. 04·How a job goes

Five steps, and none of them are a surprise.

  1. FIG. 01

    You book in about two minutes

    Online or by phone. In summer dispatch runs around the clock, and whoever answers can see who is on shift and where they are, so the window you are given is a real one rather than a hopeful one.

  2. FIG. 02

    We measure before we diagnose

    Superheat, subcooling, static pressure, temperature split and amp draw. Those numbers separate a low charge from a failing compressor from a duct problem. Looking at the unit and having an opinion does not.

  3. FIG. 03

    You get the price in writing, before we start

    The price is agreed before we start, and it does not move. It covers the work described, not the hours it takes us. If we open something up and find a different job, we stop and re-quote rather than adding it to the invoice.

  4. FIG. 04

    We commission it and hand you the readings

    Charge verified, airflow set to spec, static pressure measured, temperature split confirmed at the registers. You get the numbers in writing. An uncommissioned system quietly loses a large slice of the efficiency you paid for.

  5. FIG. 05

    It is guaranteed, and the guarantee is short enough to read

    Two years on our labour, and whatever the manufacturer gives on the equipment. If the same fault comes back inside that, we come back and it costs you nothing.

  6. The whole method, written out, including what happens when we get something wrong.

FIG. 05·The work

Typical jobs, and what makes each one tricky.

These are the kinds of work this valley generates, and the part of each that decides whether it goes well.

Two condensers on a level concrete pad with insulated line sets running up a stucco wall in straight parallel lines.

FIG. 02

A two-system changeout, commissioned

Both systems sized from a room-by-room load calculation rather than from what came out. The line sets are the giveaway on a good install — straight, supported, insulated the whole way.

New insulated flexible ducting running in smooth even runs between roof trusses to a sheet-metal plenum.

FIG. 04

A duct run replaced, not patched

The old run was kinked over a truss and crushed under stored boxes. Thirty feet of correct routing did more for the back bedrooms than a larger system would have.

Filter reachable without tools, condensate run properly to a drain with a float switch. Half of what makes a system last is whether anyone can actually get at it.

FIG. 07·Questions

The ones people actually ask.

How fast can you get here in a heatwave?

In summer we run dispatch around the clock and we will tell you the real number on the phone. If we are four hours out we say four hours. A company that manages your expectations with vagueness is not doing you a favour when it is 112°F.

Do you charge extra for nights, weekends or summer?

No. There is no after-hours surcharge at any time of year. The diagnostic fee is the same at midnight in July as it is at ten on a Tuesday in March.

How does the pricing work?

The price is agreed before we start, and it does not move. We diagnose, quote in writing, and that number is what you pay for the work described. If we find something the quote did not cover we stop and re-quote rather than adding it at the end.

Are you licensed?

Yes. Arizona ROC Licensed · C-39 Air Conditioning · EPA 608 Certified. Arizona licenses contractors at state level through the Registrar of Contractors, so you can look any AZ contractor up on the ROC website before you let them in — ours or anybody else's.

What is the guarantee?

Two years on our labour, plus whatever the manufacturer gives on the equipment. If the same fault comes back inside that, we come back and it costs you nothing.
