Had Just In Time (owner's name is "Justin") come out to try to maintain 2 old furnaces from the mid-70's, so that we wouldn't need to replace them. They were fine, they certainly put in a great effort to keep them running properly, but alas they needed to be replaced. When the service person called Justin for a quote on a new furnace, saying I wanted a mid-efficiency, he was told they didn't have any left, so I said I'd shop around over the next month (it was no rush). We had Just In Time out again for a duct cleaning, inquired again about mid-efficiency furnace, he called, and voila they apparently had 2....hmmm. 2 weeks later, and they found 2? We ended up going with another company (Sun Valley HVAC), because install cost was about double with Just In Time, by the way.
