Best Plumbers Inspect in Houston TX

Called for furnace tune up. They refused to do the tune up because the credit left belongs to the last owner of the property. Since, I am the new owner, the transfer of credit cannot be done. I have to pay for the new tune up service under my name. Even the previous owner of my house said that this was a non sense excuse.Suggestion: you saved one tune up but lost a potential customer. Is it worth it?
