Quarterly maintenance and filter change out. The 2 main units upstairs are having minor issues that we are working through. The filter racks in these two units are becoming obsolete. I converted one today to a more updated filter and will convert the other next time we come out for the a/c in the spring. Last time we were here we fixed a venting issue on the upstairs unit and it is working much better. The tellers unit has a similar issue that we will also want to take care of in our next tune up in the spring. All equipment is operating at this time.
