Angler Heating & Air's trained technicians service all manner of name-brand air-conditioning units to ensure sustained, comfortable climates for families and businesses. During a tune-up, technicians complete a comprehensive check-up of the chill box, seeking out leaks, inspecting filters, and shooing off vacationing penguins. Pressure and amperage are carefully tested, belts and coils are cleaned and checked, and motors are subjected to rigorous scrutiny by the tech?s trained eyes. Angler also replenishes one pound of freon free of charge, while additional pounds are $30 each (not included in the price of this Groupon). Technicians typically zip to homes and offices for same-day service, barring a full schedule or a sudden ice age.
