ITEM 2
Company was called to diagnose and repair my HVAC system, a Trane XE80, which is a common system. The repairman diagnosed as a bad control board and told us we had two choices, buy a new system board or install a whole new unit for $7000. It just so happened he had a replacement unit on the truck and it would cost us $980.
Later that day I looked at the unit he replaced the control board with and found it was a Honeywell S9200U1000 available everywhere for somewhere between $80-170 bucks: https://www.google.com/search?q=s9200u1000&oq=s9200u1000&aqs=chrome.0.57j0l3j61.3677j0&sourceid=chrome&ie=UTF-8#q=s9200u1000&safe=off&source=lnms&tbm=shop&sa=X&ei=fC3LUZL3Lbas4AOc7oDoCg&ved=0CAsQ_AUoAw&bav=on.2,or.r_cp.r_qf.&bvm=bv.48340889,d.dmg&fp=31a254b48afda3a7&biw=1130&bih=927
Getting a vague feeling of uh-oh, I called a couple of competitors to get quotes on replacing a control board and received five quotes around $300-350 and one for $500.
ITEM 3
A copy of the contract, disclaimers, and the old part were not left at the time of the repair. A violation of Ohio law, and by which time I received a contract and disclaimers, the company had already refused to negotiate the price.
Resolution pending in Ohio Small Claims.
Go elsewhere for your HVAC needs.
