On Sunday, I caught my AC blower leaking down in the basement. A representative from Allegiance arrived bright and early on Monday to help me out. The technician tackled multiple potential causes before pinpointing the issue – a clogged condensate drain line. Notably, this line was located in a tricky spot. Despite that, the tech managed to locate the blockage, clear it out, and swap all the old PVC pipes with new ones. He also re-routed the drain line in a better configuration. I'm thoroughly satisfied with Allegiance's prompt service and response time.
