The Speed Report
Every ranked Arizona HVAC town, worst first.
252 HVAC sites across 41 Arizona towns, measured in July 2026 on Google PageSpeed Insights, mobile. The 22 towns with 5 or more sites are ranked by median score. One trade, one state, every site we could find in it — run yours against the same tool and put it in the list.
One square is one measured shop; the column it sits in is the score it came back with. The middle of the Arizona HVAC market we measured is the 61 column. The 18 teal squares in the 90–100 column are every site in the corpus that cleared 90 — the only ones on this page permitted to be teal.
By town
Scottsdale is the bottom of the table at 49 and Cottonwood the top at 70 — which is the finding underneath the finding. The distance between the worst Arizona town and the best one is 21 points, and neither end of it passes. Towns with fewer than 5 measured sites are not listed, and 55 of the shops we scanned had nothing to measure at all.
The wait
It is 112 degrees, the AC is dead, and the page is still white.

Not one of them is a photograph. Every named cause at the top of that list is code the shop was never told it was carrying, which is the entire reason this is fixable.
What a number is worth
The only claim this site makes about speed is a comparative one, and this is the table it is computed from. Read a row as: a shop scoring this beats that share of the Arizona HVAC market we measured.

Ninety is the mark Google publishes, and clearing it puts a shop past 92.9% of the Arizona HVAC market we measured. That is the whole claim. There is no version of it that mentions rank, traffic, or where a machine decides to put you — and outside Arizona HVAC there is no corpus behind it, so it does not get made.
