What we did
A diagnostic visit to a Berea home in June 2025 turned up performance issues with the HVAC system. The home uses a mini-split system with multiple zones, labeled A, B, and C, which made careful testing important.
We ran tests on the system in collaboration with tech support from Dura Star. That testing showed irregular voltage readings at Zone A, so we replaced the board for that zone. Zones B and C remained inactive. Working alongside Dura Star's tech support helped us confirm the readings and target the replacement to the part that needed it.
Multi-zone ductless systems are a flexible way to heat and cool different parts of a home, but each zone relies on its own electronics to run properly. When readings come back irregular, a methodical diagnosis keeps the repair focused instead of swapping parts at random. The work we completed sets the system up for more reliable operation going forward, which matters through Kentucky's hot summers and cold winters alike. We handle mini-split diagnostics and repairs for homeowners in Berea and throughout Madison County.
