Condensate Drain Pipe Maintenance
I am a homeowner seeking a professional opinion:
In early July I had a technician service my heat pump system - my primary objective was proactive cleaning of the air handler's drain pipe. The tech blew some forced air through the pipe and spent thirty minutes going thru a spring start-up checklist.
Thirty days later, my system shut down; the cause: clogged drain pipe. Another technician, another hour's labor. The HVAC company has not offered any reduction to me in recognition of their recent, planned service call. They insist that clogs happen, sometimes frequently.
Is this true? I am grateful for any insight. I wasn't looking for a freebie from the company, but is there no implied warranty on work like clearing a drain pipe? If not, proactive clearing of the pipe would seem a waste.
Details: There is no real seasonal start-up for this system: year round heating and cooling provided by an all-electric Carrier Comfort Puron Heat Pump system installed five years ago. An Apriliare 5000 HEPA filter feeds the system, which has been problem free, except for a clogged drain pipe Summer 2007, and again this year. I live in the Northeast...we did have a super humid hot season this year.
Thanks in advance; this website and your services very appreciated.
