Ok service, ok associate




everyone I've talked with or worked with previously was great. This particular associate needs a little refresher in customer service. When asked exactly what service(s) he'd be performing as part of the check up, he looked shocked as if he'd never been asked that before then struggled to find the words. When at the end he indicated a part was needed and I asked what the part was and what the issue was, he actually said "how do I explain this". I'm well educated son, I'm pretty sure if you use English and explain it at a laymen's terms, I'll be able to understand.

Absolutely love DiBiase and cannot recommend them enough. I've been with them a few years now and bought a new system through them. I trust them so much I'd leave them in my house if I couldn't stay. Shacole in the office is awesome and gets everything set up and ready around my schedule. Bryan was the tech this time and he's great.

Technicians were great throughout the entire process. They were at my home for about 8 hours and were very respectful of my home the entire time. They worked efficiently and neatly.After they completed the job they tested all the equipment and made sure I was happy with what they had done. They answered all the questions I had and made sure I understood everything they did.

Everything went very well and on time!

Performed Precision Air CondItioning Tune Up on system. Air Filter was very dirty. Need to check Air Filter every 30-60 Days and replace as needed. Changed the 16x20x1 Air Filter. Cleaned EZ Trap and cleared Drain Line through Union Connection. Inspected Electrical Components on Indoor and Outdoor Units. Measured Refrigerant Charge of system. System is running to standards. If purchasing 16x20x1 Pleated Air Filters do not exceed the MERV 8 Rating. The Higher ratings can obstruct Air Flow and cause issues with the performance of the system. Was informed that the unit was making a Shaking noise when it turned off. Cycled System multiple times and did not hear/see anything that was out of the regular operation. The Compressor will make a slight louder sound when it turns off, but this is normal operation.The office will follow up on Friday 8/10/18 to complete billing of the Service Membership.

Refrigerant pressures were within operating conditions while system was in Test Mode: 50 PSIG, 52.9 VSAT, and a 3-10 Degree Superheat.

No AC . Found system low on charge . I would recommend to have the system replaced due to the age and status of the equipment . Homeowner would like a quote for a new system before charging the old one up . I talked to joe . He will be out tomorrow to give the homeowner a quote . If the homeowner decides to charge instead of replacing it I already built a estimate for it .

Found living room larger unit splitting condensate through the fins. Checked all drain and pan connections. Checked unit leveling as well. Noticed poor temp splits when both units were running. When just the living room unit would run it would not split condensate. Found unit to be low on charge. Added refrigerant to bring splits to standards. 20-25 delta. If problem occurs again we will need to look for a leak.

Found unit not running outside and air handler running. Found unit flat again with no charge in unit. Inspected unit for leaks at indoor and outdoor units and found significant dye around outdoor coil. Outdoor unit is not elevated and coil failure may be caused by ice damming.Call customer in morning to follow up with coil or unit or system replacement.

Upon arrival found filter dirty, system low on charge, and a little bit of water in pan by wet switch. Replaced filters, added refrigerant and dye, insulated small piece of suction line that may have been sweating to cause water by wet switch or the water could have come from a defrosted frozen coil before my arrival. System is running to specifications at this time. Concerns are that when heating season arrives the system may pie over charged due to coil size difference when switching to heat.
