Blown in insulation worth it? and cost?
Just as the question asks, is it worth it? And what is the cost?
I have a 1200 sq ft ranch house with a basement.. Blown in insulation 10" thick in the attic along with new roof 2 years ago.. This last month with the high propane costs I got a $875 bill, and now im searching for answers.. Today I replaced the old nasty rotted insulation in the upper basement walls (above the foundation and below the sub floor) with r-21 rolled up fiberlass insulation.. I got to one part and realized that the insulation coming down through the walls was r-11, and probably as nasty and rotted as the old stuff above the foundation..
Can they blow it in with old insulation still in there? Would they just remove it? Is it all worth it? What will my cost be do you think? Standard 8' tall walls, 1200 sq feet home.. Original single bedroom part was built in the early 1900s and a much larger part was added on in 72, dont know what the original part has or if it was updated with the r-11 with the rest of it.
The location is central michigan.
Does anyone have cost estimations of any of this? im looking for ideas i can pay for with my middle class tax return haha

Too many unknowns, and you don't even give the location.
If there's no insulation at all in the 'early 1900s' section thats
probably your biggest heat loss.
Even the future weather is a question. This has been a 50 year winter. Are weather patterns changing or is it an oddball?

It is hard to say. If your propane is costing too much, you might want to consider getting a heat pump. A heat pump is an AC that can run in reverse. They only work down to a certain temp. Mine works down to thirty degrees. Once it dips below 30 degrees, then it uses propane. Heat pumps are very efficient. They are 2-4x more efficient than straight electrical. It probably wouldn't cost you anything to have an HVAC company give you a quote. Some even have affordable financing. If the HVAC company says heat pumps don't work in your area, look for another provider. With newer technology, heat pumps work great even in colder areas.

Insulation of one type or another can be put in or blown in almost anywhere. I'll go sideways and suggest, while more is almost always better, what's really needed if you can do it in your location, is to get away from LPG heating. The prices are going nuts, and this will not be the last time. Good luck. Get some bids, on any such major energy use/HVAC upgrade.
