I have a few questions about the system equipment I plan on having installed and also a referral for a "quality" HVAC contractor in the western suburban Chicago area.
My house is about 1,000 square feet, 37 years old (original HVAC equipment) with R-13 walls, way too little blown-in attic insulation, and leaky single pane windows (all of which are on my "list" of things to get fixed - Once I find a job!). My "better half" really prefers Trane (it's what my mother-in-law has) but an American Standard system would also be fine.
Equipment list -
Trane XV95,60k BTU, variable speed furnace - TUH2B060A9V3VA
Trane XR13, 2.0 Ton, R-410A, AC - 4TTR3024A1000A
Trane 2.0 Ton, Cased Coil - 4TXCB025BC3HCA
1. What thermostat would you recommend? A Trane unit or a Honeywell IAQ?
2. What humidifier would you recommend? Trane unit or an Aprilaire 500 / 600?
3. What about the coil? I was told in the past that a 2.0 Ton AC system is more "efficient" when matched with a 2.5 Ton coil. There also appears to be a "High Efficiency" coil available - 4TXCB003CC3HCA. What makes it more efficient (appears to be a bit larger in height) and is it worth asking about?
4. I am totally ignorant about the "filter". I am only used to the cheap, 1" filters that you replace every month. I don't think I want an electronic $$ filter, and really don't know about the details of a 5" media box. Why does one contractor want to build this box and one want to buy it pre-fabricated?
Can you recommend a "quality" HVAC contractor in the western suburbs of Chicago that would want to work with me (please see my "Everlast" comments in this thread - http://hvac-talk.com/vbb/showthread.php?t=292812 )?
