Scheduled an estimate for what we thought would be a complicated fix. Arrived on time, pleasant, thoroughly assessed the situation, made his professional recommendations, and didn’t try to upsell me on any extra repairs that weren’t urgent, and actually let us know that the wiring situation didn’t require an expensive replacement or re-wiring, just someone comfortable with that specific wiring and hardware layout. Would call them again.
