Customers Say

Buyers frequently report quieter operation and stronger airflow compared to 20–32 year old furnaces, including a 110,000 BTU 80% model described as having a fan three times more powerful, and one user citing about 30% lower energy costs after replacement. Installation is often described as easy for DIYers and professionals, though some noted freight damage, a missing inducer wheel clip requiring a push-and-lock O-ring replacement, thermostat compatibility issues, or website sizing errors.

I had delivered an ACiQ 80% 110,000 BTU furnace. It is working great. I replaced a high efficiency 90% Bryant that had a known secondary heat exchanger issue. I watched The DIY HVAC Guy on youtube that recommended that all high efficiency units are crap and to go back to 80%. He couldn't be more right. The unit is running fine with no problems. The install was easy. I had to redo the ducting as per his instructions. The price i paid $1,300 compared to what Bryant installers wanted $13,000 was a no brainer. If you have mechanical hands and like stop watch How To youtube videos, get this one! You wont be disappointed. The heat is excellent a d the fan is 3 times more powerful than I used to have. Excellent unit thay will last 30+ years.

We have installed about 6 of these, replacing williams wall furnaces. They work great. after 2 years, be sure to clean ignition sensor. That's the only thing we have done, other than clean filters.

This furnace was almost the same size as my 32 year old Carrier I replaced (6" shorter). CS was able to change order and I received the right size. Fast shipping and shipping damage. The new ACiQ furnace is quieter than the old one. Temp-Rise test was in range with factory settings. Saved a bundle and very happy with this product.

Very pleasant buying experience and faster delivery than I ever expected. I was thrown one small curve when the unit arrived and it was a different brand than originally ordered. Did some checking and found they were in the same corporate family and the only difference is the sticker on the front so it’s no problem.

FAQ's

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.

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.
