Upon entry into the house, customer currently does not have a water heater in the unit because the unit is currently under construction. Customer stated that the gas is currently not turned onto the building because she has to get it turned on from the city and once she gets it turned on from the city she was going to call us back to commit to the job. At this time she did not want to commit to the invoice due to not knowing when she was going to turn the gas onto the unit.
