Reliance Home Comfort

Purchased new furnace to replace fully functioning but aging furnace.
Salesperson pleasant. Installed on schedule (June 5, 2012).
June 10 - five days after install - was the first day warm enough to verify functionality of furnace to any extent ... temp in the high 80s.
Furnace & AC unit (also a Reliance purchase) running non-stop with thermostat set a 75. Upstairs temp = 85, main floor 81, basement 68. Found no cool air coming out of vents in half of main floor and all of upstairs. Cool air coming out of vents in other half of main floor. Until the new furnace was installed all vents put out air flow from furnace.
Called Reliance to report problem. Person at Reliance said that if the fan on the furnace is running it is not a furnace problem, Reliance would not service this, and that I need to call a plumber. When I asked if she said a plumber, she said yes, a plumber. So, there's Reliance service for you ... brand new furnace 5 days old with temperature 5 to 10 degrees warmer than thermostat, vents mysteriously not working since install, and I'm on my own with a suggestion to call a PLUMBER !
When I asked it it was safe to run this system Reliance did not give me an answer. So I shut it off and moved the family in the basement for the night where at least it was cool enough to sleep.
Eventually the Reliance service department called me back and said that it looks like we had this unit installed 5 days ago, which is what I told her from the outset. She told me that our unit was under warranty and that a technician could be at our place in 2 days.
I relayed all of this to our salesperson who at least listened well to the problem and said that he would do his best to get someone there earlier.
Impressed: NO Disappointed: YES
