Reviews for 3.5 Ton 15 SEER 96% AFUE 100,000 BTU ACiQ Gas Furnace and Heat Pump System - Upflow/Downflow-R410A

This coil will directly replace any of the Carrier branded (Bryant, Payne, Day and Night, etc.) N-coils. I removed it from the casing and installed it in an existing coil cabinet. Without any modifications. No sheet metal mods were necessary. Works perfectly after 2 seasons. A lot of the original N-coils using 410 from Carrier failed early on. This product will save you from replacing your system.

Relatively Easy Install. Lots of extra parts are included, that are needed for several models, so don't worry about something being an extra item. If you convert to Propane, make sure you change out the valve springs and reinstall with the exact number of turns for HI and LO. The power wires are in the Power Vent section, not the control panel area. The universal vertical/horizontal unit is excellent product choice.

ordered online to ship to wisconsin, got here in a couple days. Got it with a lift gate so it was an easy delivery. Installation was done in a day and was pleased with the build quality and performance. Been running a couple months now with no issues.

We are satisfied customers. Works great!

Product works great it is whisper quiet can hardly hear it running at all like our old one. Turns on and off during the day whereas our old unit would stay on all day long trying to keep the house cold. Very satisfied with my product.

I have worked with this equipment for several years. installation was easy with my past experience. Saved a lot of money.

Install went great. Would recommend to anyone. Thanks!

I've been running this evaporator coil in air-conditioning mode for a month now. It performs beautifully both as an air conditioning condenser and a heat pump heat exchanger. It fit perfectly atop my AirQuest furnace with no modifications necessary. Rather than an "A" shaped coil, this is a "W" shaped coil which gives more heat transfer capacity for 4 ton and larger air conditioning units. Along with my AirQuest air conditioner & heat-pump, and the ION System Control thermostat, this combination is good at keeping the house comfortable. Although AirQuest is an unknown brand name to me, I believe it to be a Carrier brand name product, renamed. I installed this evaporator coil and an air conditioner & furnace myself with 4 hours of help at the end from an HVAC professional. There were experts, (Chris Whitmore) at HVACdirect.com available to help me through the uncertainties and this was very valuable. I've only tested the heat-pump side of this unit so far but look forward to using the heat pump this upcoming Minnesota winter. Doing the labor myself & buying from HVACdirect.com saved me ~40% on the system & installation cost.
