I just bought a single-wide trailer that was "remodeled"

I just bought a single-wide trailer that was "remodeled" inside. They say that the floor and walls were redone, and that the insulation was too. I have lived in here since March, and when the summer started getting closer, the house would not cool down and the "all in one" AC would run all day. I don't have the air handler inside the home. I kept it on 78 degrees at first, and noticed that it was running all day, from around 10 am, until 9 pm. I bought this trailer from the mobile home community, and have been complaining about it for months. I get home at 3pm daily, and I noticed the thermostat would say 87 degrees. So I bought a small 5,000 BTU window unit and also a 12,000 BTU portable on wheels unit to cool the living room, which has a raised ceiling. So I'm sure there is no insulation with the cathedral-like ceiling. I've had HVAC folks come out and they have stated that there is nothing wrong with the AC. It blows cold, but just doesn't seem to have enough "blow power" with the blower. They inspected the ducts in the floor, and patched up a few areas in numerous vent ducts. It still has not kept my home cool. The only time the trailer cools off, is if it is overcast all day, raining, or when the sun goes down. It's in direct sunlight all day. When the sun goes down, my house cools down to 76 in about an hour. And over the weekends, I set it to 74, since my girlfriend is here, and needs it cooler overnight. No issues cooling overnight at all. Will it help for me to have a bigger unit installed? I have a 2 ton unit right now, and they "suggested" moving up to a 2.5 ton unit. Is that going to solve the issue that I have with cooling? Will that unit push more air out of the vents to actually cool the house? Also, if I have a new unit installed, what do I need the HVAC guys do? What do I need to make sure to get done, so I don't miss anything, and they don't miss anything? Sorry for all the questions, just looking for "options". Oh, and my trailer size is 14'x80'. The unit intake is is by the back room, and the back room (master) has the AC unit right outside the windown. So that is the coolest part of the house, at all times. Just hate that my unit runs all day, and does not shut down for 13-15 hours straight a day. Thanks for your help!

I just moved into a house that is 10 years old. The AC unit

I just moved into a house that is 10 years old. The AC unit came up as an item to watch but not defective on the home inspection because it was "beyond it's normal useful life". The unit was unable to keep up with the summer heat in August and would be, for example, set to 73 but could go no lower then 77. Then I got my energy bill which was through the roof, almost $400 for 1,800 square feet. I had a company come out to do a maintenance on the unit and came back with feedback that there were a lot of red flags and it should be replaced. For example, when pulling off the panels the insulation was falling off, touched the inside of the unit and sparks flied. He taped that back on. Then he pointed out there was "biogrowth" on the air handler (top part of the unit), said it wasn't draining properly and R22 refrigerant could be leaking into the house. He also said the engine was running at 29 out of 30 so it was running at capacity.He looked at the compressor outside and pointed something out about the capacitor saying those things don't get put in unless someone knows their unit is on the way out. (It may not have been the capacitor but was right next to it?) I mentioned it was a good thing I have a home warranty, and the guy immediately discouraged me from using them because he said the work they do is bare minimum to make code and wouldn't really do enough because they don't want to pay for the replacement of a unit. (Which I could see as a possibility) Here was his suggestion:NEED REPAIRSBlower Motor (cost $698)UV System ($380)POTENTIAL PROBLEMSEvaporator coil $2,246Compressor $2,137RECOMMENDED:- Duct cleaning- Upgrading system ($4,800 for seer 13 / basic unit for upgraded York multispeed humidity control, seer 16.75 (4 ton), 10 year labor warranty ($600 value), UV light ($200 "at cost") with instant rebate is $8,000.I went to my home warranty company, (paid $65 total as part of deductible) didn't tell them about this and had them examine to get second opinion. They felt the capacitor on the compressor outside needed to be replaced and did so, were not going to open the panels because they said there's rarely anything going on in there, however I insisted and they decided to change out the capacitor for the motor, saying it wasn't at maximum but was elevated and that the rust was normal it deals with water all day. The unit is 10 years old and should last another 5 to 10 years.So as you see... two very different opinions! The first guy seemed to paint a grim picture but did a more thorough check (including going in the attic to check the ducts) but was pushing an upgrade. The guy from home warranty wasn't too concerned and almost didn't even open the unit until I insisted..... Do I need a THIRD opinion?? I guess that's why I am here. Who is right?

From searching online, it looks like I have two HVAC return air vents in my TV room. They are extremely noisy if I am using air conditioning and I can hardly hear my TV, unless I put the volume loud (inconsiderate to neighbors). What can I do?
