Big problem for new homeowner!
I bought a 60+ small ranch, 1,000 sq ft, that had been heated by coal/wood. When I turned up the thermostat, heated air blew out the two cold air returns. I have scoured the internet to discover the problem. HVAC man says 'reversed ducts'
Now, there is no way I am going to believe this was accidental. That the wood furnace was moved out and the gas furnace moved in without noting where the blower was set. So it it was intentional was it done to heat just the core of the house when the owner was away for the winter? Doesn't make sense.
What about a power surge? I have a sewer easement right under my bedroom window, as my lot is downhill, this would create a lot of ground currents and perhaps stray voltage?
Possibly the owner had the furnace wired to run off a portable generator? We have outages up here in UP.
What about another issue I saw in the forums? A clog in the blower nipple? The entire ductwork had for years been receiving coal/wood air so probably was full of soot, specks, etc.?
That would explain why the HVAC man wants to put in all new duct work.
But these issues go back to the fact that my house had significant undisclosed problems when I bought it. I do not want to buy existing problems. So I need a straight-up description of the problem, not a side-step that leaves me up the creek. I bought it from a retired lady which I also am so we are the same financially.
Goodman furnace is 2010, 46,000 BTU slightly undersize for house. Winter is closing in and I am heating with portable ceramic heaters which I was told by the rep from UPPc will run to an extensive power bill BUT it is necessary to clarify what is what before I take any action, I think.
