Came to residence for complimentary first year ac tune-up on a '20 ac system. Equipment functional upon arrival. Upon inspection of the outdoor condenser, I found all electrical and mechanical components are operating properly. All my electrical measurements are good and the unit is functioning well. Moving inside, I found the Aprilaire 210 media filter is in good shape and doesn't need to be changed for at least another 6 months. The blower and evaporative coil are clean and the airflow in the system is very good. I changed the filter reminder setting on the thermostat to 9 months, as that will be close to the time it should be checked and/or changed again. See health report card for any specific information. Homeowners complimentary Western Savings Club Membership expires in five months. I also mentioned that we now offer annual water heater maintenance as part of the maintenance program. Equipment functional upon departure. Thanks for your business and have a great day!
