Hi -- I'm looking for some general advice. I have a HydroHeat 4-ton unit installed in 2000 that heats our house - in Canada - with hot water for the radiant heating and hot air for the rest.
In 2007, after 7 years, the compressor jammed and had to be replaced. Now, 2 years on, the replacement has just jammed again and I'm looking at another $ bill.
Both failures were sudden, not preceded by low heat, failure to cycle from hot water to hot air, noise, or anything else. In fact, when the system is working, it's fine.
So my question is this: are HydroHeat units known to burn up compressors? Assuming the distribution system in the house is well installed and well balanced, is there something specific within the unit that could be causing a problem that doesn't show up in faulty performance? Both compressors were Bristols -- should I switch to another brand of compressor?
And the follow-up question: at what point should I cut my losses and install a new unit?
Thanks for any advice.
