Do they make furnaces that work on weekends?

[Owen Dashner]

I would pay double for an HVAC system (plumbing too, for that matter) that is guaranteed to never break down on weekends.  I think like 99.5% of my HVAC and plumbing service call requests at rentals occur from 5:01 PM on Fridays to 11:59 PM on Sundays.

That must mean you have tenants that are at work during the day which I would consider a huge positive.  At least they are letting you know of the issues before they become more costly as well.  Could be much worse :)
