It's been ages since I've been on here! I have an UltimateAir DX200 ERV for which I need to buy replacement heat exchange/filter media and drive belt. Is UltimateAir, Inc. still in business? I get no answer to phone or email messages. Stirling Technology, which has the same address and phone number, web site appears to be somewhat dormant also.
Anyone know what's going on with them?
