Jacob McKinnis performed an outstanding Spring Precision Tune Up on our two (4 & 3 ton) systems this morning. Both systems were thoroughly inspected and he replaced both UV lights and Perfect Air Purifier filters. The quality of Jacob's service was outstanding in every way and has become the standard for Jon Wayne. He was extremely polite, knowledgable, and dedicated to ensuring the customer was totally satisfied. I would welcome this professional for every future Precision Tune Up. I would, however, highly recommend that Jon Wayne supervisors ensure their service people show up at customer's houses with the products that are required to complete the scheduled service. This is meant as constructive criticism only because I consider Jon Wayne a cut above every other HVAC company. If a customer requires two filter replacements during a Precision Tune Up, I would expect a Jon Wayne service person to show up with the required filters. Planning ahead would eliminate this oversight (granted it may appear to be small, but it's very noticeable by the customer). Jon Wayne should know what each customer's system/s require and then ensure this info is made available to their service people so that they have all necessary filters/lights, etc to complete the job. Overall, I am completely satisfied with the service rendered by Jacob and welcome him back in our home for all future inspections.
