I am a skilled professional that works for a Dor-Mar Heating & Air Conditioning company. I recently completed an estimate for a gas line installation for a customer. The customer wanted to install a gas line from the meter to their furnace. I measured the distance between the meter and the furnace, then used a pipe sizing calculator to determine the appropriate size of pipe for the job. I also obtained the necessary permits from the local building department and scheduled the installation with the customer. The installation went smoothly, and the customer was happy with the results.
