OVERVIEW

Inverter Technology - Inverter technology converts AC power to DC, allowing the compressor inside your condenser to speed up and slow down. This enables the system to automatically self-adjust BTU output based on demand, ensuring optimal cooling performance as the weather changes.

Learning Condenser - Equipped with advanced sensors, this condenser monitors air temperature inside and outside, overall system performance, duct pressure, and refrigerant temperature. During the initial startup, it enters a learning mode to optimize efficiency for future operation by continuously gathering and storing critical data so future startups and run cycles will be at max efficiency.

Optimized Cooling - The self-adjusting inverter design allows the condenser to operate all the way down to a 1 ton unit when needed, keeping you cool and comfortable, making it an ideal seasonal device for hot climates where additional air conditioning is needed for homes already heated by boilers, fireplaces, or other sources of heat. For optimal performance, pair the ACiQ-4X-AC unit with the ACiQ-48-ACL coil.

QUICK FACTS

  • 12,000 BTU to 42,000 BTU variable output based on demand
  • Inverter air conditioner system designed for use with ductwork
  • Efficient cooling from 5°F to 122°F outdoor temperatures
  • Durable Gold Fin condenser coil coating
  • Quiet operation even at the highest workloads

42,000 BTU, 15.5 SEER

With an efficiency rating of 15.5 SEER, the variable output ACiQ-4X-AC will keep you comfortable across a wide range of conditions. Use our handy size calculator HERE to determine the demand for your home. For cooling, this system can operate anywhere from 12,000 BTU to 42,000 BTU without short cycling.

Customers Say

Buyers report strong performance and noticeable energy savings, including a 3 ton 18 SEER inverter heat pump in a dual fuel setup in Iowa that has already saved hundreds of dollars, a system cutting one user’s electric bill by $150 per month, and another using half the electricity while running much quieter than an older unit. Installation is often described as straightforward, with one self-install completed in three hours, though a few noted startup or communication issues, a bad controller thermostat replacement, minor shipping damage, and a missing 3/8” line set pipe.

    My a/c quit last fall. After some research I decided to do a full replacement of both units. After placing my order there were some out of stock issues. Nicholas was great in helping me get substitutions for my order. There were also some concerns about the delivery. He was great in coordinating the day and delivery time. Thanks again for great service !!

    I installed this unit last weekend along with a matching coil during a heat wave. It performed perfectly. I like the 2 stage function. It drops to the 1st stage when it reaches thermostat set temp and maintains house temp using less energy. I hope this unit performs for years to come, but so far I am very happy especially the price I purchased it for.

    Only time will tell when it comes to long term reliability but I have confidence I'll not need to make any claims during the 12 year warranty period.
    Happy to be an HVAC Direct customer.

    PS. Don't trust other shady sellers whose tag line is "At these prices our air conditioners won't last" 8-)

    I received our ACiQ Condenser & compressor within 7 days of order. Minor issue with a dent in 1 corner of the condenser unit without affecting the performance. I would recommend HVAC Direct to anyone seeking quality products, excellent service, knowledgeable employees, rapid delivery and great pricing.
