Need advise on replacing our 5 ton air conditioning unit
I am currently in the market for a new air conditioning unit. The evaporator coil on our existing unit is shot and the cost to replace it on a 9 year old unit doesn't make since.
We have gotten estimates from 5 companies so far and the prices and what they think we need are all over the place. It has been quite an education. What we do now is we want a 16 seer and we know we need 1 additional return.
We have been quoted on Trane, Rheem, and Lennox. I was advised by a friend to look at off brands like American Standard because the parts of all the units are made by Honeywell anyway. Is there any truth to that?
We also need some type of special filter or light to help with my son's allergies. The recomendations on these differ as well. One suggested a MicroPowerguard, another the Trane Clean Effects then there are the uv lights, standard, included in some quotes, or the ultra max.
Sorry for the long post, I am hoping someone can shed some light on all of our options.
