AC Repair, Install & Replacement in Montgomery, NY

Got called out to a commercial building on a rooftop package unit — a Carrier 48XC, roughly 12 years old. Found a failed dual run capacitor (35/5 MFD) that had completely discharged; the compressor was attempting to start but drawing locked-rotor amps and tripping the internal overload. Swapped in a matched replacement cap, let the overload cool down, then ran the unit through a full load cycle — pressures came up clean, delta-T was 18 degrees across the coil. Back up same day.
