I posted here a while back about an Ameristar hvac system that was installed in my attic w/the evap. coil facing the wall and completely inaccessible. It turns out there are several other problems w/this install, not the least of which is that the installer flat out lied about having a permit for the job. Another problem is that the furnace he installed - a CDX080 - is not as quiet as he promised it would be. The attic is my office and having this thing kick on and off right next to me is going to be a problem. It turns out my installer can't fix the problem w/the coil and can't (or won't?) get a permit, so I'm thinking I might have to let him go and bring in someone who can do it right.
I called in the company that does my hvac servicing to take a look and their guy said this Ameristar furnace is crap and recommended pulling it out and putting in a Carrier Infinity 96. He said this unit is so quiet I won't even know it's running most of the time. And the coil will face forward so it can be serviced, if need be.
My questions are, is the Infinity 96 as quiet as he says it is? Is there an American Standard unit that is just as quiet? And, if so, would it be better to stick w/American Standard given that the outside unit (which he doesn't plan to change) is American Standard? In other words, is there any problem w/compatibility between a Carrier furnace/coil and an American Standard condensing unit?
