38 HVAC jobs completed in Danville since June 2023.
The York furnace had lost power
The furnace would not start because the fuse in its wall-mounted disconnect had blown. After replacing it, we ran several heating cycles over about half an hour. The original reason for the blown fuse remains unknown; another failure would need a fuller electrical diagnosis.
Reworking a leaking mini-split installation
A garage mini split stopped cooling about four months after installation. Testing found refrigerant leaks at the flare connections, including split copper at a sealing face. We shortened the excess line set, remade the flares, straightened the drain and evacuated and recharged the system. The photos show why adding refrigerant alone would have left unfinished work.
Check the Town boundary before a permit application
The Town of Danville Permit Center asks applicants to verify that the job site is inside the Town boundary. Its page links a boundary map for that check and lists adding or replacing HVAC among projects requiring permits. Use that boundary check before selecting the permitting authority for an installation.
