Sherri,
I know this information is posted on the link to my other thread on the same subject but I can't recommend Master RV Mobile Service (407-348-0862) highly enough. The guy that came out was great and definitely knew RVs inside and out. The price was very reasonable and I would use him again.
I had them come out on a Saturday because it was real cold and my furnace was on the fritz so I paid a $75 weekend service call fee plus it was only $97 to fix my furnace. The guy was very thorough and spent an hour taking it out of the RV, cleaning it, fixing the orifice and re-installing it. It was installed behind the cabinets so it was alot of work getting it out. You can't take an RV into a repair shop for that cheap plus we didn't have to take it anywhere. He takes checks or cash only. Give him a call.
