What does ‘on the double’ mean?

I was laboring on a furnace last week, as well as the owner of the cabin sat on the steps watching myself and others the entire time; He kept telling me, on the double, appreciate he was a staff sergeant laboring with his modern recruits, however i wanted to tell him to stuff his ‘on the double’, even though I was the Heating as well as Air Conditioning serviceman as well as he was paying me.

I was sure that if I said something to him, he would call the Heating as well as Air Conditioning supplier as well as I would be in a lot of trouble.

I held our temper as well as continued laboring on the furnace, however when I checked the air filter, I almost laughed out loud. I asked the owner when he last changed the air filter in the furnace? He looked taken aback as well as told myself and others he changed it regularly. I showed him the air filter as well as said I thought it was time to have the air duct cleaned if there was this much dirt in a week. It was a laugh out loud moment when he said he changed it regularly, even though he didn’t say they changed the air filter yearly. It was just numerous people in the house, as well as he didn’t know it was necessary to change the air filter once a week. I still thought it would be a good plan if every one of us were to call the Heating as well as Air Conditioning supplier as well as have the air duct cleaned; Even if he had the air filter changed every many weeks, there shouldn’t be this much dirt in the air filter. He agreed with myself and others as well as headed upstairs to make the call to the Heating as well as Air Conditioning supplier.
