Replacing furnace, ac, and humidifier on the North Shore of Chicago. Not much east of here except lot's of water. Nice lake effect cooling going on though.
Increased the return air drop and opening on furnace from 20" to 24". This will help a little with the struggling ductwork.
Installed metal flood safety pan, vibration pads,

Furnace: Cimfortmaker 90,000 Btu's 80% efficient, ECM blower motor.

AC: Comfortmaker 2.5 ton capacity, 13 SEER efficient, R410-A refrigerant, Comfortmaker condensing unit.
Installed filter dryer, line site inspection glass, matching 2.5 ton cased evaporator coil with TXV, full A2L compliant refrigerant safety mitigation sensor and wiring.

Humidifier: Generalaire 1137 power humidifier.

Aluminum safety flood prevention pan and vibration pads.

Electronic automatic flood safety cut off switch. And yes the control wiring to it is wisely strapped into place to prevent accidental movement of safety device.

AA Mechanical above and beyond.

Was able to hack into my old hard drive that crashed and found the AA Mechanical reviews that Google deleted on my company. Take that! Many more to post here and share everywhere including Google.
Excellent Service, Very Knowledgable‎

Our furnace died at about 3pm on 12-22-08. I Googled for heating contractors, saw the great reviews, and called Walter. He came out by about 4:30pm, assessed our situation and determined that our 18-year-old furnace was no longer safe to operate. Walter then did a complete load assessment of our home, went to his office to crunch the numbers, and had a hard price back to me via e-mail by about 8pm. He proposed replacing our oversized 147000 btu 78% efficent Carrier furnace and A-coil with a properly sized 70000 btu 95% efficent Goodman furnace and A-coil and would have the new unit installed and operating the next day, The total installed price was slightly more than double the wholesale cost (I checked) of the materials (furnace, A-coil, thermostat, intake and vent stacks, condensate pump). Included in the price was complete removal of the old furnace and clean-up of the jobsite. Based upon my experience (20-years Building Inspector) this was an excellent deal and I signed right up. ...‎ More »

I called AA Mechanical the morning my furnace went out and they were there within 15 minutes of my call. Within a short amount of time they were able to diagnose and fix the problem which turned out to be a bad igniter. I also received many tips on filter choices and general furnace maintenance which will help extend the life of the furnace. I would definitely call AA Mechanical again if I ever had a problem. Fast, professional, and courteous.‎

I told the customer I gave this ac unit it's last rights.
From the customer.
Wow, that looks much better. It aligns with the building across the street. It looks now like it is good for another 20 years!
