NVM = not very moral! Used them via assignment from our home warranty contract administrator. Their tech arrived to check out minor humming noise with a big hearty smile and told me that he would treat me and our furnaces as good as he treats his own father and his old man's equipment -- I should have smelled the rat right then. He proceeded to diagnose serious water leak potential from what he described as furnace condensate drain pipes that I subsequently learned from my regular HVAC service company were for air (like the vents above sink traps) -- not even for water -- and posed no threat of the dire consequences that the HVM guy forecasted if we didn't have him do major (read $$$) prevention projects to save us from the imminent flood. He even told me that his boss was a real stickler -- especially on home warranty contract work -- and that often meant that the warranty insured customer didn't get the repairs that the warranty contract promised unless the homeowner was lucky enough to get this guy to make the service call. Sounds like this company has real problems within itself and well as with potential customers. Conclusion: if it all sounds too good to be true, . . . well, you know the rest.
