If you call a random HVAC company, they may not want to deal with "fussy clients" that want something "fancy" like an HRV/ERV. Best to look at folks that perhaps try to adhere to building science more. A quick search for the LA area:

* https://www.aircomfortexperts.com/additional-products/ervs/

* https://www.azaircond.com/indoor-air-quality/energy-recovery...

Or do a dealer search from a manufacturer, e.g.,:

Any climate. Modern ones can even handle IECC Zones 6 and 7:
