Please let the service guys know that came here today? Another exemplary home service visit by Hillside Oil. The men did everything they could to describe the issue to me, and to show me reasons for the diagnosis. They encountered a slight problem while working. The replacement reduction valve they installed had a crack in its casting. So they needed to unsolder and remove it and install another.
The crew chief told me they would have been gone an hour earlier. It’s these little bits of candor that endears a customer to your organization. We know we are being told the truth and that the work we are getting is first class.
He even warned me of the age of my system. It’s apparent, 3 service calls in 6 months? So, while I will attempt to milk one more year from my furnace, I am forewarned that I should prepare for the worst.
I will ride my Crown Bahama until she decides it’s time to become chassis parts for a Ford SUV. But rest assured, when the time comes for a new install, it will be Hillside Oil that I call for the installation.
I’m notifying by this avenue because, while your tech did provide me with a prepaid postage survey card, the life expectancy of postcard-sized cardstock in a home with the number of cats and dogs is roughly 45 minutes. Anticipate significant perforation.
Thanks for your understanding as regards my capabilities handling finances, and thanks for exemplary service once again.
