<s>[INST] Comparing the price of various services around Pittsburgh

This week, I was disappointed again by the high price of running a cleaning service. I feel that other services that are much more complex and human resource intensive are cheaper. For example, until I changed it a few months ago, my home's heating bill included a biweekly visit from a oil delivery company to oil change the furnace in my house. Those people use big trucks, build huge storage tanks, and complex equipment, and travel long distances. But the cost was only $1,376 per year for heat! Cleaning services just cost $1,127 per year.

As you write your response, I would be interested to know if there are options to reduce this bill. 

You'll be likely like cleaning a home is not as resource-intensive as oil delivery. But for others can cleaning be as resource-intensive?[/INST]
