4 Ton 17.5 SEER 96% AFUE 100,000 BTU ACiQ Gas Furnace and Heat Pump System - Multi-Positional

Since installing few years ago, this heatpump has been wonderful. The rotary compressor is incredibly quiet. One crucial point to note, the air handler or furnace must be of same brand or the communication will not work between thermostat heat pump and furnace. My furnace is goodman, and I do have this issue but was able to use the heatpump and the different stages anyway. Great heatpump, and it looks great too.

A complex thermostat has a lot steps, procedures, and settings. Having a readily available and knowledgeable service support is really appreciated.

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.

Great customer service, great agent, fast delivery, a kind of fair pricbut Thank You for your service over all.

I'm using most of the features this controller offers and it was tricky to get my old ventilator working with this new HVAC system. When we exhausted the knowledge in-house at HVACdirect.com, they referred me to a local expert who stuck with me until all capabilities were functioning perfectly. One thing to know about this controller... If running a whole house ventilation system... there is a 1-1/2 minute delay before the furnace fan begins to do its part. That delay kept me wondering what was wrong for a few weeks but now it all works perfectly. Highly recommend HVACdirect.com and the ION system controller.
