STAY AWAY FROM THIS GUY.
Robert Weinlood of Heating and AC Las Vegas sold and installed for me an Aprilaire and UV bulb into the AC and heater also purchased from him. When I went to replace the filter I did notice that he had sealed via tape, the wrong type and silicone the entire humidifier. He did this near the install time as it was leaking and that was his jimmy rigged fix.
I called Aprilaire for some information and for a recommendation to have someone else deal with it, as having problems with Weinlood prior I would not again allow him on my property. When I advised the Aprilaire rep of how the install leaked and Weinlood simply jimmy rigged the unit with tape and silicone to stop the leak, they were aghast at this information. I further described how the unit was set in on an approximate 25 degree angle, thus forcing the water to the corner and causing the leak. They advised me that now it simply leaks inside and onto the coil.
Aside from any damage that could be done, it most definitely is affecting efficiency according to Aprilaire the manufacturer. Additionally I was told that the unit for best performance should have been set up to run off the hot water and not the cold as Weinlood had it with the jimmy rigged copper piercing attachment rather than a T valve. Therefore at the moment, without being able to change filters and especially where the heat is now constantly on, I am getting little humidification as well as not being able to service the unit with the new filter I purchased (filter requirement was something Weinlood also neglected to inform me about). Further the UV air filter was installed in the wrong location, a mismatched plenum used and Weinlood neglected to fasten the AC coil to the unit with the required four screws.
