110,000 BTU, 80% AFUE
The ACiQ N80MSN1102120A has an input of 110,000 BTU. With an efficiency of 80%, this means that the furnace has an output of 88,000 BTU. The 80% AFUE also means that for the gas going into the furnace, 80% of it is used to heat your home while the remaining 20% is lost out the flue piping and lost to normal furnace operations. All 80% furnaces require metal flue venting, and if you need it to be plastic/PVC venting a furnace with an efficiency of 90% or above is required. While this unit uses natural gas as fuel out of the box, we also have an LP conversion kit, available at an additional cost. Please note that this furnace is not Low NOx or Ultra Low NOx compliant and if shipped to California may be subject to a mitigation fee.
Warranty
ACiQ offers 10 year parts and 20 year heat exchanger limited warranties.

Buyers report noticeably quieter operation and stronger airflow than 20‑ to 32‑year‑old furnaces they replaced, including an 80% 110,000 BTU model described as having a fan three times more powerful, with one owner citing 30% lower energy costs and another saying it runs one‑quarter as often as their 30‑year‑old unit. Installation is frequently described as easy for DIY or licensed installers, though some mention redo ducting, a missing inducer circle clip requiring a push‑and‑lock O‑ring, a thermostat return due to incompatibility, freight damage, shipment substitutions, sizing issues, and minor delivery delays.

I had delivered an ACiQ 80% 110,000 BTU furnace. It is working great. I replaced a high efficiency 90% Bryant that had a known secondary heat exchanger issue. I watched The DIY HVAC Guy on youtube that recommended that all high efficiency units are crap and to go back to 80%. He couldn't be more right. The unit is running fine with no problems. The install was easy. I had to redo the ducting as per his instructions. The price i paid $1,300 compared to what Bryant installers wanted $13,000 was a no brainer. If you have mechanical hands and like stop watch How To youtube videos, get this one! You wont be disappointed. The heat is excellent a d the fan is 3 times more powerful than I used to have. Excellent unit thay will last 30+ years.

At present we’re not using the heat but unit is performing well with external AC unit.

We have installed about 6 of these, replacing williams wall furnaces. They work great. after 2 years, be sure to clean ignition sensor. That's the only thing we have done, other than clean filters.

This furnace was almost the same size as my 32 year old Carrier I replaced (6" shorter). CS was able to change order and I received the right size. Fast shipping and shipping damage. The new ACiQ furnace is quieter than the old one. Temp-Rise test was in range with factory settings. Saved a bundle and very happy with this product.

Very pleasant buying experience and faster delivery than I ever expected. I was thrown one small curve when the unit arrived and it was a different brand than originally ordered. Did some checking and found they were in the same corporate family and the only difference is the sticker on the front so it’s no problem.
