1st - Thanks everyone who contributes to these forums. They are a great source of info, and helped me choose a system.
We hired a fully licensed HVAC contractor to put in a carrier infinity furnace, central air, and both EAC and media air filters (our family has bad allergies). Unfortunately, the estimator didn't measure everything out and there isn't room in the utility closet to add either of the Carrier brand filters. They did finish the job and put in what looked like a $0.50 green coarse-grain filter to protect the cooling coil in the near-term.
My question is, what do you recommend we do? The options I can think of are:
1. Only put in a 1" media filter in the furnace housing. This is pretty tricky as the Carrier Infinity furnace has electrical wiring blocking the right side entrance (so a disposable filter will not slide in), and also requires removing an interior access panel that is screwed in.
2. Put in a media filter in the return air vent. Unfortunately, our return air grill is only 16 x 10 for a 1400 sq ft house. The furnace we have is 60k BTU matched with a 3T AC unit, and I'm concerned that a filter here might restrict the return air too much.
I'm interested in having a licensed HVAC tech do this of course, but the comany we went with is being pretty flakey. I think if I do the deciding on what we want, they'll come and do it, but their estimator is pretty busy now that the warm season has started...
Thanks for any thoughts...
