In Scottsdale, near East Shea Boulevard and North 78th Street performing routine seasonal maintenance on an Amana package heat pump. Cycled system on in cooling. Checked volt and amp draws. All in factory specification. Cleaned and tightened electrical connections. Checked Freon levels and pressures. Acid washed outdoor coil and rinsed. Changed return air filter and checked splits. System has had a capacitor added to the system. Customer also stated he was getting noise from the system; tightened up the blower assembly. Recommend adding waffle pads and up sizing the duct work to help that vibration noise from the system. Package unit is running proper at this time. Customer wanted to try the vibro pads for now, but does not want to do any up sizing to the duct work.
