I think a hotel could be a good idea.

Try calling Davis and Davis. Many companies will make a fuss unless you already have a maintenance contract in place, but they came out for us several years ago despite not having one.

We're in the Bethesda area.

We suspect it's the blower. Who do you recommend we call, what is it likely to cost, and is there any hope someone can come out tonight, on Christmas Day?

Thanks!
