I recently completed a comprehensive heating and air conditioning repair service for a client. The initial assessment revealed issues with both the heating and cooling systems. I meticulously diagnosed the problems, which included a malfunctioning thermostat and a refrigerant leak. After replacing the faulty thermostat and repairing the leak, I conducted thorough testing to ensure both systems were functioning optimally. The client was pleased with the restored comfort and efficiency of their home's climate control systems.
