    Smile Allergy Fighting Infinity Install

    My 1965 Chicagoland ranch home no longer suffers from a noisy, rattling 1992 Carrier Crusaider gas furnace and ancient Williamson AC. While functional, it was noisy, not so efficent anymore, and didn't help my allergy condition (dust mites, pollen, & grasses). The return system was undersized by about 400 CFM and was causing short-cycling of the furnace

    (1) 4 ton Carrier Infinity gas furnace and AC

    (2) Aprilaire 5000 air cleaner

    (3) Aprilaire air damper, 125 CFM - sized and connected to return air to create positive pressure in the living space - reduce pollen infiltration

    (4) Aeroseal ducts (21% duct leakage reduced to about .7%)

    (5) 2 enlarged return vents. (With the damper, the return system is now where it should be. Return vents are much quieter now!)

    I want to thank everyone here for your making me a better HVAC consumer. I made a list of the allergy-related HVAC needs I had, the complaints I had against the old furnace/AC system, and my preferred timeline to get the new system in. I used that list to get 3 written estimates from local authorized dealers of good manufacturers (Lennox, Carrier, Trane), preferably that my colleages recommended. I carefully evaluated all three estimates, not just on cost, but for manual J and D measurements, how well they listened and responded to my needs, and their reputation. The Infinity estimate was neither the cheapest nor the most expensive but the best all around for me.

    What's up with the tyton straps crushing the tubing insulation?

    No sleeve for the lineset through the masonry wall?
    Clearly a code violation where I'm at.

    Looks good from what I can see.

    i would've sleeved the lineset and sealed the hole through the wall.

    I see a mechanical humidistat. Somebody probably installed it out of habit. It has no business on any Infinity system, be it for humidification or dehumidification. Have them come back and wire it correctly.
