I live in arizona, it is hot.. I have a modular home, aka mobile... it is a double wide. My problem.. only half of my house is being cooled with the airconditioner... cold is is blowing out of the floor vents on one side.. the other has nada, not a thing. Does anyone know what is happening... (Please don't tell me I have to crawl under the trailer...) Oh, I know it doesn't matter but I am a woman.. so I will need explicit instructions on what and how to do anything.

SonWorshipper - hi, you did post this in the wrong area but many of us look here off and on. Has the A/C ever worked in the half of your house that's not currently getting cold air? If it did at one time, then something's blocking the A/C ductwork or else it's fallen apart...most likely, underneath the trailer.

Has anyone worked underneath your house recently? Maybe they closed off the ductwork and forgot to re-open it. Also, have you tried to fully open and close the vents on the half of your house that's not getting cold air? Sometimes, the vent dampers appear to be open but they're actually not.

I hope this helps you a little...hopefully, a friendly neighbor or good friend has someone they can send over to do the crawling around underneath your house. Good luck! Jim D/West Point, VA
