A compressor in an Arizona home does not get much rest between cooling seasons. Homes in Arizona run heat about five months a year, from November through March. That brief heating window is almost all the downtime the cooling side sees before it is asked to run hard again, which means a marginal installation, one where the equipment was sized close to the edge or set up without enough attention to the load, will reach its limits sooner than it would in a place where the compressor sits idle longer. A contractor quoting your house is working out how much room the system has before that matters.
A quote for a new AC system starts with what is already in the house, and in Arizona that means ductwork and electrical service that have to be opened and measured before a specification can be written. Half the homes in Arizona were built in 1992 or earlier (2020-2024 ACS 5-year). A system sized right for the load still depends on ducts that move air without leaking and a panel that can carry the draw. Those two things vary by how the house has been maintained and modified, not by when it was built, so a contractor works from what the inspection turns up rather than from assumptions about what should be there.
Does your Arizona county put extra stress on HVAC equipment?

A condenser sitting outside in Arizona faces more than heat. Hail dents coils, wind drives debris into fins, and blowing dust clogs filters faster than any manufacturer's baseline assumes. A unit sized and positioned without accounting for what the local record shows will work harder and fail sooner. The licensed contractor you are matched with reads that exposure before recommending equipment, not after.
Arizona HVAC Contractor License Requirements for Installation and Repair
