Hoot Heating & Air 84

When our furnace quit in the middle of a cold snap, Hoot Heating & Air sent a technician out the same day. He was friendly, explained exactly what was wrong, and had us back to warm in a couple of hours. No pressure for extra services, just honest work at a fair price. I appreciated that they didn't try to upsell me on a new system when the repair was totally doable.
