Our old gas furnace died. I read posts on this forum for hours and hours and researched as best I could. Ordered a Goodman GMV950704CXB Multiposition, Two Stage, Variable Speed Gas Furnace. (No A/C)
Here are my questions, what thermostats can anyone recommend?? (I'd prefer a programmable one And, we'd like to have the option of using the furnace blower to circulate air in the summer.)
What wire types do I run for the tstat?? Can I get that specific wire from Home Depot??
Also, the old furnace closet had a 6" x 12" duct that ran from mid furnace level into the attic - for air intake I presume. New furnace is 95% efficient and only requires 2" pvc for exhaust thru room and a 2" pvc air intake into end vented attic. Can I rip out the old duct and seal up the holes in the closet?? A friend said I needed that duct in case there was a gas leak...I thought gas fumes are heavier than air...so I disagreed with him. So, can anyone help with these three issues...
Thanks in advance!!!
