Performing diagnostic service on 2014 Trane condenser that is running but not blowing cold air. Upon initial inspection noticed the compressor motor was not on and only the fan was running but very weakly. Diagnosed failed dual capacitor (runs fan and compressor motors) and replaced per owner, also added hard start kit to protect compressor motor and prevent the issue from happening again. Clients are now Certified members and we look forward to working together for years to come! Thank you!
