When the cooling quits in June, a slow page reads exactly like a closed business.
Nobody in this situation is browsing
The cooler stopped and the house is at ninety inside. A storm cell backed water up against the parapet overnight. A hard freeze split the supply line to the roof unit.
They are not assessing your workmanship. Three things, fast: you handle swamp coolers, you come to the Lower Valley, this is the number.
Heat is a real emergency here
A house without cooling through a desert afternoon becomes dangerous quickly, especially for older residents. The people searching are worried rather than curious.
Put the response time high on the page in plain words. That one line wins more calls than any design decision on the site, monsoon runoff or not.
Assume the phone is already struggling
Storm traffic loads the network, the Valley has thin coverage anyway, and a handset in this sun slows itself down. Those three arrive together.
Build for the customer out on the Lower Valley and the easy one takes care of itself. Words first, images after, nothing blocking the render.
Buttons for a squinting, sweating thumb
Standing on a roof or in a caliche driveway, one hand on the phone, screen barely readable. Small links crowded together simply do not get pressed.
Make the call button genuinely large, keep it on screen as the page scrolls, and leave empty space around it so nothing else takes the tap from a hand that has been dealing with a swamp cooler for an hour.
Put a stopwatch on it
Next call out on the Lower Valley, let the phone get hot and then try to book yourself through your own form. Time it.
The number usually lands badly. What you approved indoors is not what a customer meets standing over a swamp cooler.
