Our HVAC contractor showed up on time, diagnosed the weird rattling noise in the furnace within 20 minutes, and had the part replaced by lunch. He even walked me through the maintenance checklist and didn't try to upsell me on a whole new system. Honest, skilled, and actually respectful of my schedule.
