I am buying a house in Washington area and going to have to replace an oil furnace in the crawl space under the house. The house was built in the 40s, square footage is about 1500(500 is add-on on the back), 1 story. The current furnace is leaking CO. We plan on living here less than 5 years. My questions are:
1. Can I do work on the house and use the furnace, but keep the windows open, before we move in (refinishing floors/painting)?
2. We have been told my two estimates that we need to switch to gas from oil and I think the reasons were because we wouldnt be able to remove the current furnace completely and couldn't fit a new one in. I may be mistaken. The one company (very big name in the area) said that he couldnt put a new furnace back down there and would put it in a closet in the house and vent through the roof and could put an 80% in there. The other one said that he could put a 90% in there (if we first enlargened the crawlspace opening) b/c he was sure he could do that, but only half sure about an 80% installation being successful down there, not sure the reasons. Can anyone explain why that would be?
3. Finally, the first guy said his company was too busy for something like that, and the 2nd guy gave 3 bids (all Trane): 90% XR Standard ; 90% XL 2-stage ; and 90% XV 2-stage Variable-speed. What type of furnace should we select, he said the 1st is a dinosaur in his industry and its really loud? I'll still get 2 more bids, but wanted to know more info before I do.
Thanks a bunch for any help!
