- Rated for efficient heating: Operates down to 5°F outdoor temperatures.
ACIQ Standard Series 1.5 Ton 18.8 SEER2 High Efficiency Heat Pump Condenser - R454B Inverter
OVERVIEW
Inverter - The ACiQ-18-EHPD 1.5 ton central inverter heat pump utilizes inverter technology to convert AC power to DC, allowing the compressor to adjust its speed. This enables the condenser to modify its BTU output based on the current demand, providing efficient and adaptable performance throughout varying weather conditions.
Learning Condenser - Equipped with advanced sensors, this condenser monitors indoor and outdoor air temperature, duct pressure, refrigerant temperature, and overall performance. During the initial startup, it enters a learning mode, optimizing future operations for maximum efficiency by collecting and storing data.
Adaptive Sizing - With its self-adjusting inverter design, the ACiQ-18-EHPD can be sized based on your heating needs. Standard heat pumps may cause discomfort during summer when sized for heat, but this unit automatically adjusts to function like a smaller unit, ensuring ideal cooling performance without excess humidity.
QUICK FACTS
- Variable output based on demand: 12,000-18,000 BTU for cooling, 12,000-18,000 BTU for heating
- R454B refrigerant
- Inverter heat pump system for ducted applications
- Efficient cooling from -13°F to 122°F outdoor temperatures
- Reliable heating from -13°F to 75°F outdoor temperatures

Installation and Maintenance
Installation is very similar to installing any replacement air handler. Your technician will make electrical, refrigerant, thermostat, and communication connections. Plus, they will connect the air handler to your return and supply ductwork. The ACiQ central ducted air handler is multi-positional (upflow, downflow or horizontal), making it a very versatile air handler. Any 24v thermostat with 2 stages of heating can control the system. Supplemental electric heat kits are available as a backup heat source for the coldest days of the year. If any maintenance is required, the intelligent control board in the air handler displays fault codes in case any part of the system experiences issues.
Please note - in order to function, this air handler must be installed with a condenser and other installation equipment, available at an additional cost if not already included in this product bundle. To use straight electric heating, an electric heat kit is necessary and is also available at an additional cost.

- 2 ton split unit to replace trane installed in 2008Excellent equipment, I have an old friend in the HVAC biz. Quoted $8600 for a "Better" Goodman installed. I had installed an Inverter package in my Mom's house a few years ago and was very impressed with Function and efficiency - and wanted the same for my master suite. I went ahead and had the 'professionals' install it for $1050 and still saved MORE than 50%. They were very impressed with the unit and ease of install (2 wire thermostat) - plus my wife thinks the blue tooth phone setting is Cool - and the $4k we saved took us, the kids, and all the grandkids for week long beach Trip! Happy wife - Happy life!!

- All the great thing you hear is trueMassively simple wire hook up 2 wires from the t stat down to the air handler and two out to the condenser. Little braze work I let nitrogen set in the line overnight for one it was late in the evening at that point. Was a late start doing this install. And two I never fully trusted compression fittings. ACiQ did an amazing job with theirs not a single drop in pressure over night! next morning pulled a vacuum down and released the 410 built a new plenum and the customer had cold air blowing by noon. Did a follow up with customer a week later they love their new system, homeowner was concerned with the condenser sitting outside his small Childs bedroom window. of the noise. stated he has to walk outside and almost two feet away to really hear it running. price point and ease of installation I would highly recommend an ACiQ system to everyone

- A Quality Heat PumpThis ACiQ heat pump is quiet and quite efficient when paired with an ACiQ indoor air handler in serial communications with each other. It’s well made but there are design issues. There is really no protection for the heat exchange fins. A stray stone or tree branch can easily damage this unit. The the power and communications compartment is not water proof. This heat pump will need to be protected from hard rains. The high side pipe is 5/8” and the low side is 7/8;” are unusual sizes that were harder to source where I live. And the price is higher than it should be because it’s just a rebranded Midea (Senville comparable) heat pump. It didn’t even come with an ACiQ sticker on it!! Should be around $800 to $900, not $1800.

- FANTASTIC UNIT!!!!I'm not an HVAC professional, however I do have rudimentary knowledge of how things work. This weekend I replaced our 17-year-old 2-ton condenser/3 ton coil with a ACiQ-36-EHPB, 3-ton coil, and lineset. After a bit of futzing with ductwork and creative thermostat wiring, I have the unit up and running with the existing gas furnace set up for AUX heat.
I have to say that the install was relatively smooth. We moved the condenser from the south side of the house where it baked in the sun to the northeast side where it is shaded most of the day. I had to add 12.5 oz of refrigerant to top off the additional length of line and everything works great. 22 degree drop across the coil and pours water out of the condensation line.
The ACiQ-36-EHPB is eerily quiet. My sprinklers make more noise than the condenser and fan does. Also, this has the softest of soft starts. The compressor slowly spins up from 0 which is perfect for people who may need to run this from a generator. I tested mine and it ran with no problem. This is in contrast to never being able to start the old one, even after buying a soft start.
I am extremely pleased with the ACiQ-36-EHPB so far. Also, HVAC direct was great to work with, got the unit out the door fast, and I will definitely shop here again.Posted on
- My initial sureveyAs of this moment, i cant drop a survey for we are still in diagnostic with some issue to be resolve. Meantime, 3 star is at hand but after resolving i will get back for my final survey.
