Is there any general rule for the cost of the inside HVAC work compared to the outside drilling work?  For example, it is approximately a 50-50 split or 20-70 split?

Thanks

Thanks, I looked at your web site too.  For example, from your web site take the retrofit of the medical clinic where the heating and cooling costs were reduced from $8,960 to $1,280.  What was the cost of installation?  Did the drilling make up most of the cost?  What was the payback?

Thanks again,

We didn't do the install on the medical clinic. We just used the case study.

If I were to make a very rough estimate it would be drilling is 30 % to 50% of the total cost of the job. But keep in mind that costs can vary greatly from job to job.
