We bought our coach last February and have been having a/c issues since last summer. It has a TrueAir basement system, which we thought we would love. The heating system works great but the cooling system can't seem to keep up with temperatures at 90 and above. We have had to replace circuit boards, a relay switch, both blower motors and a fan over the course of a year. Each time we think it's fixed for good as soon as the temperature gets really hot it still can't keep up. As we speak, they're now doing a freon check (because the temperature coming out of the vents is reading slightly higher than it should be). If it's a freon leak we will probably get two new compressors. If not, the Tech is saying that brand just may be putting out as much cooling as it can( as with the factory installed units on all Alfa motorhomes. That company then started offering an option of adding a rooftop unit to compensate for the basement unit.) Our Tech is suggesting we may have to do the same.
We have an extended warranty and so far they won't authorize a new unit because we haven't completely exhausted all possible solutions. Can anyone contribute any advise/solutions on this? We love the coach but this is driving us crazy. A rooftop unit would be installed in a cut out already housing a vent so the job would probably cost about $1200. It would be located in a central area so air flow would supposedly flow forward and back. Spending the money on this is one thing...as long as it solves the problem.
