Haha, nahh, never a good idea to have power to something when you're installing bulbs, it somehow causes a disturbance in the force and can foul up stuff....most times I've only seen it burn contacts, but it could pop fuses(or circuits if no fuses nearby)....your HVAC is evidence of that. Well I've ordered my reverse LED bulbs from my supplier, so they should be here in the next few days and I'll send ya a pair if they perform much better than stock.
