For weeks, my 5 year old window air conditioner made a loud buzzing noise when the cooling compressor kicked in - Then would be fine and cooled until it shut off silently - But then when the thermostat said it was ready to cool for the compressor to turn on, again the buzzing sound (like at the end of a period in a hockey game) - but Now, the compressor doesnt work, no cool air, but the fan works fine. I still hear the buzzing sound like it is trying to turn on, but cant. Anybody know how I can fix this ?

Hi Folks- I have just started trying to work on our HVAC system. It's an attic unit, horizontally mounted with a furnace, evaporator coils, and a duct box in that order from the return downstream. It has a number of issues the most obvious of which is the rusted out auxiliary drain pan. I've got a new drain pan on order, but I also want to clean the coils and seal the box up while I'm working on it. My problem is that I'm not sure how to safely remove the access panel to get at the coils to clean them. The unit is hung from the rafters by metal straps, and one of the straps is screwed into the coil access panel. In another area I can see that the frame of the unit doesn't extend as far down as where the strap is screwed in to the panel; I believe the strap is attached *only* to the panel and not through into the frame (see last picture). Can I remove this strap and open the panel while I clean the coils without being in danger of damaging the unit or, worse, having the whole thing come crashing down? If not, any suggestions on how to support it while I remove this panel to work on it?
