Additional Notes

Complaint: They are charging to much for the work performed.and didn't do any of the work originally requested. I hired prange's to install 2 garage heaters that I purchased from menards.the first one needed to finish the gas line I already started . And to hook up the exoust. The second one needed to be hung and gas line ran and the exoust to be hooked up.they said it would cost between $400.00 to $600.00 . When they came to start the job they said they couldn't do anything until I got a gas regulator for the main supply line from the gas company. They were only here for 30 minutes that day. When the gas company came to install the new regulator . Pranges was here also to put another regulator on my house furnace so it would work with the gas change pressure. They ran about 16 ft of copper line from the main to the house furnace and hooked up a new regulator to the house furnace. They were here for an hour . And said I would have to make an appointment for the original work to be done for the garage furnaces witch I ended up installing myself. When Prange's called I told them that so they said they would bill me out for the work performed. When I revived the bill it was for $560.00 . Witch I believe is to much money for the work performed. I contacted them and asked how could that be . They said that's what they came up with. I asked them if they would have done the original work to be performed also that it would have been twice as much. They said no it would still been the same amount.

Desired Settlement: I wouldn't have a problem paying a fair price for the work performed

Business Response:

The price we quoted was a ball park figure over the phone. We billed him time and material rate. After talking with the customer and going over the material cost he understood and paid the agreed amount.

Consumer Response: Better Business Bureau:

I have reviewed the response made by the business in reference to complaint ID ********, and find that this resolution is satisfactory to me.
