Issue is 4 rooms on second floor and the first floor office (immediately to the left of front entrance) is colder in both cooling and heating seasons. These rooms are above or near the garage. Took photos of the problem rooms and exterior of home garage side and two bedrooms on the front of the house. I closed the dampers on (4) 6” ducts slightly to slow airflow there This problem is related to building performance as well. Replaced 16x25x1 filter for 1st floor system provided by homeowner. In discussion with homeowner he and a friend have serviced the units and have charged them refrigerant. Verified fan speeds at first and second floor furnaces for both heating and cooling using blower performance charts. 1st floor furnace Good Was able to lower cooling fan speed for, hi (black) to med hi (blue) for second floor system Recommend upgrading thermostats to smart thermostats with room sensor especially for the second floor system. 1st Floor system is 100k BTU Goodman propane

I have used another company for the last 30+ years and when I needed this HVAC servicing quickly was told it would be sometime in September (now July). I asked a friend who they used that was reliable and they said "Barry with DiBoise" was their preferred technician and company by far. I called got an appointment quickly. Barry was not only extremely good technically but also was excellent at explaining to me why and how the service steps would help improve the operation of my HVAC as he performed the Service. I heartily recommend DiBoise and hope you are lucky enough also to get Barry!
