Friendly, prompt service. I have been a customer for many years and would not switch to another company.
Timely service.
You have always taken good care of me and my 2nd home / lake home in terms of ensuring that I have adequate propane supply when I am not there (winter months primarily). I appreciate that. I have confidence in my supply and that my billing is accurate.
Consistent delivery.
The delivery service is excellent, especially with the cellular tank level meter.
Not as happy with: Dropped servicing and annual inspection of furnace
When I requested a stake-out in 2021 prior to underground electric service to garage, only one copper propane line was staked. Electrician dug up two others. Fortunately electrician turned off at the tank before digging.
Then it took a few days to have the propane lines repaired. Seemed sloppy and quite dangerous. All propane lines were installed by Phelps Sungas.
