A failing capacitor often shows as a humming AC unit that won't start, random system shut-offs, or a visible bulge/leak on the capacitor itself. Given our hot summers, capacitors work hard and can fail. If you notice these signs, call us for a prompt capacitor replacement to prevent a complete system breakdown.
