Fantastic customer support.
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.

Review by Terry (tlbud) Linton / (Posted on 24/06/20)
Nice efficient unit.
I've been running this unit for a month now. It performs beautifully and is very quiet & vibration free while running. It consumes about the same energy as my 18 year old Lennox did, even though the Lennox was 1/2 ton smaller. Along with 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 and a furnace 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 cost.
