I got a trane vendor come by, very nice guy did his partial calc. Instead of selling Trane's Cleaneffects he quote me on micropower guard electronic air cleaner (Nature's home). the price is a little lower, but does it do the job? Anyone heard of this product? I only got 3 results searching this forum.
Also he say he perfer to use "timing" on the 2 stage variable speed using the Trane touchscreen thermostat. it sounds reasonable to keep furance on the 1st stage for 10 minute (5,10,15) before it kicks into full 80K btu. Or should I just ask them to let the thermostat decided when to go full power? he say sometimes the location of thermostat plays too much part into when it kicks into full power.
is there more reading about timing vs auto?
