AC installation service here means more than swapping hardware: San Diego homes require a Title 24 HERS rater sign-off on new systems, and our coastal zones need equipment rated for salt-air exposure.
Mountain installs often call for dual-fuel: a heat pump for efficiency most of the year, with gas or electric backup for the handful of true cold nights. We quote both configurations so you can see the tradeoff.

Smaller than a contractor's rule of thumb, usually. Every home gets a Manual J load calculation that accounts for square footage, insulation, window type, orientation, and ceiling height. Oversized systems short-cycle, leave humidity, and wear out faster. Rightsized wins on comfort and bills.
