I am in Portland, OR and I have the ERV installation scheduled early november. It will be a Trane Fresh effects 200CFM. Home is a 2700 sq ft home with a Trane XV90 (variable speed fan) furnace and a Trane Heat pump. I have been monitoring the CO2 levels inside the house and it averages 600-700ppm. In the thick of winter I expect it to be worse and hence the ERV install. The unit will be installed in the garage (insulated) and ducted to the furnace. Please provide feedback on
1. What are the things to ensure? For example, I read that in one installation, the installer didn't insulate the intake and exhaust which resulted in a major redo. I want to avoid things like that. Please recommend if such insulations are needed.
2. Length of runs for the intake and exhaust? Any requirement on how far they have to spaced apart?
3. I have a honeywell f200 in-line merv 12 filter. Sometimes I use merv 13 and am considering Merv16 Lennox during cold/flu etc. Does the percentage of time the ERV comes on, have any implications on the filteration system in terms of how often to replace filter and workload on the furnace, thermostat settings etc
There will be holes cut out in the garage wall to accommodate the intake and exhaust. Any precautions to be taken there. Basically any feedback or recommendation you have will be much appreciated.
