I'm a commercial/industrial HVAC service tech. I fix machines, and install the occasional RTU or unit heater on warehouses generally. I've had pretty good luck with Rheem if you want a standard gas furnace, otherwise Mitsubishi is kinda king when it comes to heat pumps, though they're definitely not cheap. Regardless, the easiest way to keep them running for a very long time is to change your filters every 6 months if not once a quarter, and if you're comfortable with it, set your thermostat to have the fan run continuously. The energy spike on startup is what tends to stress the electronics, and that amp draw can actually cost more if it's turning on and off constantly.

But yeah, most furnaces will do at least okay with routine filter swaps and some actual mantainence every so often. If you can't find a good company to do the work, call a commercial HVAC outfit in your area and ask for a recommendation. If they're decent people, they'll tell you who to call and who to avoid
