When my AC gave out during a heatwave last July, Hoot Heating & Air had a technician at my door within two hours. They fixed the issue on the spot and even showed me how to maintain the unit to prevent future breakdowns. Fair pricing, no pressure, and they actually seem to care about their customers.
