2.5 Ton 14 SEER ACiQ Horizontal Discharge Air Conditioner


The ACiQ NH4A430AKA AC-only condenser offers a balanced combination of efficiency, comfort, and durability. ACiQ provides this unit as an affordable air conditioning option suitable for various applications.


  • 2.5-ton, 14 SEER AC-only condenser
  • Capable of cooling medium-sized houses in average conditions
  • Horizontal discharge and compact design for space-saving installation
  • Includes field-installable filter drier

2.5 Tons

The ACiQ NH4A430AKA condenser delivers a cooling capacity of 2.5 tons, generally sufficient for cooling medium-sized houses in ideal climates. In most system configurations, the tonnage of the paired coil or air handler will be larger than that of the condenser, ensuring optimal efficiency. Please note that this condenser requires an indoor coil or air handler to function.


The ACiQ NH4A430AKA air conditioner condenser is rated at 14 SEER, providing a 5-7% increase in efficiency compared to standard 13 SEER units. This enhanced efficiency can lead to significant savings on electricity bills over the unit's lifespan.

Due to new efficiency requirements, this unit cannot be installed in the following states: Alabama, Arizona, Arkansas, California, Delaware, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, Nevada, New Mexico, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, and Virginia.


ACiQ offers a 10-year parts warranty for its condensers. To ensure warranty coverage, the condenser must be installed in compliance with state and local codes, a new and certified coil must be installed concurrently, and the entire system must be registered online with the manufacturer. After purchase, a representative will contact you to gather installation information and register the product on your behalf.

Unique Installation Potential

The ACiQ NH4A430AKA is designed with a horizontal discharge, enabling a slim form factor that saves space in your yard. Additionally, the unit tends to produce less noise towards your home, as the fan blows away from the exterior wall.

Questions and Answers

Customer Questions
Who makes ACiQ?
ACiQ air conditioning systems, standard heat pumps, and gas furnaces are manufactured by the largest HVAC manufacturer in America, who also happens to be the seller of the nation’s #1 brand. However, because our prices are SO LOW, they will not allow us to mention their name! They must protect their current market share where typical home systems retail between $15,000 to $25,000 for the identical equipment that we let you buy direct for under $3,000. We offer homeowners and contractors the highest quality and best warranty HVAC systems in the industry at the absolute lowest price. With our industry-leading, high-tech ACiQ equipment, your home and your savings just got a whole lot smarter!
What happens if this breaks down?
HVACDirect.com gives you lifetime tech support. Many common problems can be solved with a phone call to us. HVACDirect.com is an authorized dealer of ACiQ, therefore equipment we sell carries the full manufacturer's warranty. The warranty applies to all parts. You have to register the products online in order to extend the warranty to the full 10 years, otherwise the term is 5 years. If a part fails under warranty, you will not pay anything for the replacement part. Should a part fail under warranty, the first step is to have a professional confirm what part needs to be replaced. Then, contact us at customerservice@hvacdirect.com or by calling and asking for customer service.
What happens if it arrives damaged?
If you are present during drop-off and you see obvious signs of damage or rough handling in transit - please ask the driver to wait while you inspect the equipment. If it is damaged badly enough that you believe it can not function, you have the right to refuse the damaged portion of the shipment. If you discover the damage after the driver has left, take photos of the damage and send them to customerservice@hvacdirect.com. Please refer to your order number in the email. This starts the process and one of our representatives will be in touch with you promptly.
How can I find an installer?
It’s easier than you think – the key is to find an independent contractor or small company as opposed to a larger HVAC service. A one or two person outfit will do the work more quickly and cheaply than a bigger company, too. Yelp.com, Thumbtack.com, and Porch.com are websites are designed to help you connect with a professional in your area. You could also place a call to the last professional who did work on your home and see if they have any recommendations.
What's the warranty?
ACiQ’s 10 year Warranty (online registration required) is one of the top warranties available today.  Many of the higher-SEER units have even higher warranties and some of the higher efficient furnaces have longer heat exchanger warranties.
Is it cheaper to buy a furnace and AC together? (Should I replace my furnace and air conditioner at the same time?)
Remember to factor labor into the budget. Many times the labor can cost as much as the equipment. Therefore, spending a bit more now to replace everything can be less expensive than re-using an older furnace that still works, or putting in a furnace with a plan to ‘add air conditioning later.” By replacing everything at the same time, you will get matching equipment that is all warrantied together. Then you can typically not have to worry about the system for another 15 to 25 years with proper maintenance.
