To ERV or Not?
Hi, I’m having a house built in central VA (Zone 4)…2 floors and a basement (~3300 sq.ft.). Trying to build pretty tight and so we are concerned with proper ventilation. Each house in the community must meet certain standards which include fresh air ventilation to the ashrae standard. Btw…I’m pushing to get the hvac system within the conditioned space, so we are likely to have a single forced air ducted system for the entire house with manually set dampers for each floor.
Here are the options I’ve received on ventilation….
– Standard (no additional cost): Timed fresh air ventilation introduced into the return side of the air handler and using existing ducting. The ventilation and hvac blower will be linked so that both run together. (No idea yet the wattage of the hvac blower).
– Recuperator 200 ($3100): I requested a quote for the ERV. System would be installed as above for the standard with the exhaust also coming out of the return side ducting.
So….appreciate any thoughts on if the ERV is worth the extra $3k, or if I should I stick with the standard. Or perhaps…..ask that they do something different so that the HVAC blower and exterior ventilation are not linked. This site has been very helpful, but like everything else, creates as many questions as answers. Thanks.
