Quiet and Strong
Your review: I just upgraded my HVAC blower to the Ecotech 5542ET to improve air flow and efficiency of system. I wanted to have this run 90% of the time so better air mix and also cleaner air as the Electronic air filter and such only works when blower runs. I will see if there are savings as far as electric cost but that will be over time. Only issue is motor is longer due to the electronic control module that is on end of motor but for me it was a non issue but measure to be sure you have clearance!
