HVAC Shopping Made Easier

Every home and business has unique requirements and preferences for heating and cooling solutions. Factors such as square footage, technical specifications, installation process, climate conditions, and more influence your decision-making process. We understand that navigating through these details can be overwhelming for customers, which is why we introduced our ACIQ Build-Your-Own Furnace & AC System. Simply answer a few straightforward questions about your needs, and watch as the price updates automatically. With just one click, you can make your purchase. Following that, our expert sales team will match your order with the most suitable, high-quality system from our ready-to-ship inventory.

What We Need From You

The questions to answer are the same standard questions you may be asked by a contractor. Please note that not every combination may be available. All ACIQ furnaces are multi-positional, meaning that they can be installed in upflow, downflow, and horizontal orientations, so furnace airflow direction does not need to be specified. All systems utilize R454B refrigerant. If there are any issues with the selections you have provided, we will reach out to you to ensure that the system you receive is suitable for your home. For more information on each question, please see below:

Furnace AFUE/Efficiency

AFUE stands for "Annual Fuel Utilization Efficiency", which basically means that its a measure of how well your furnace will produce heat. If a furnace is rated for 40,000 BTUs and has an efficiency of 80%, then that means 80% of the fuel used produces 32,000 BTUs of heat (40,000 X 80% AFUE) per hour and the remaining 20% is lost through your venting as combustion byproducts.

Make sure you know what type of furnace your house is equipped for. An 80% Furnace will use a metal flue for venting gases out of your house, while a 90% or Higher Furnace will use plastic or PVC vents instead.

Furnace BTUs

BTUs (British Thermal Units) measure how much heat a furnace can produce. It is important that you choose the correct furnace size so your whole house can be efficiently and comfortably warmed. BTUs scale upward with house size, but please note that other factors may affect what size furnace you need.

  • 40,000 BTUs - Ideal for small houses
  • 60,000 BTUs - Ideal for small to medium size houses
  • 80,000 BTUs - Ideal for medium houses
  • 100,000 BTUs - Ideal for medium to large size houses
  • 120,000 BTUs - Ideal for large houses

Furnace Cabinet Width

Modern furnaces have a standardized cabinet width of either 14", 17.5", 21", and 24.5". Simply measure the width of the face of your current furnace to determine what width you need. Note: 14" wide furnaces are uncommon for most furnace & AC system configurations. If your setup requires a 14" wide furnace, please give us a call and our team will help you out.

Condenser Tonnage

An air conditioner's tonnage is a measure of how much cool air it can produce. Similarly to furnace BTUs, an air conditioner's tonnage scales upward with house sizes. Please notes that other factors may affect the ideal tonnage your house needs.

  • 1.5 and 2 Ton - Ideal for small houses
  • 2.5 Ton - Ideal for small to medium size houses
  • 3 and 3.5 Ton - Ideal for medium houses
  • 4 Ton - Ideal for medium to large size houses
  • 5 Ton - Ideal for large houses

Optional Upgrades

These options are not mandatory for any specific type of home. They are provided for those that want greater efficiency and more precise control over their heating and cooling system.

  • Two Stage Furnace - A two stage furnace comes with a second "middle" stage between being simply off and fully on. This second stage is perfect for those that don't want their furnace on at full blast when they do not need as much heat.
  • Modulating 97% AFUE Furnace - ACIQ's top-of-the line furnaces are 97% efficient, one of the highest efficiency ratings in the market. Each one comes equipped with modulating burner stage capabilities, meaning that they have infinite burner stage settings so you can control exactly how much heat you want.
    • Note: When choosing this option, please leave the Furnace AFUE/Efficiency option set to 80% to prevent being overcharged.

Customer Questions
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.
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!
Can I mix and match different sizes or efficiencies when configuring my system?
Yes — our Build Your Own System tool lets you select all your equipment specifications in one streamlined process. If any selected combination isn’t viable or available, our team will reach out to ensure you receive a system that’s properly sized and compatible for your home and climate. Product efficiency standards will also be verified based on your shipping address to ensure compliance with regional regulations.
How do I determine the correct Air Conditioner size (BTUs/tons) for my home?
We recommend checking the tonnage listed on your current system’s data sticker, usually found on the outdoor condenser near the electrical disconnect box. Look for terms like “Model Number” or “M/N.” These details help identify BTU/tonnage and find a suitable replacement. For new construction, consult a contractor or perform a load calculation to ensure proper sizing and efficiency.
How do I determine the correct Furnace size (BTUs) for my home?
We recommend checking the BTU listed on your current system’s data sticker, usually found on the furnace inside the cabinet door or on the inner or outer wall of the cabinet. Look for terms like “Model Number” or “M/N.” These details help identify BTU/tonnage and find a suitable replacement. For new construction, consult a contractor or perform a load calculation to ensure proper sizing and efficiency.
How do I choose the correct furnace or air handler's cabinet width?
Cabinet width refers to the physical size of a furnace or air handler's housing — typically 14.5", 17.5", 21", or 24.5" wide. Choosing the right width ensures the furnace fits your existing ductwork and coil cabinet. If you’re replacing an existing system, match the width of your old equipment for easiest installation. For new installations, consult your contractor or check your coil and plenum dimensions to determine the proper size.
What does the “80% / 92% / 96% +” label mean for furnace efficiency?
These percentages refer to the furnace’s AFUE (Annual Fuel Utilization Efficiency) rating. For example, an 80% AFUE means that 80% of the fuel is converted to usable heat, and the rest is lost through venting. Higher ratings (92% or 96%+) mean greater efficiency and lower fuel costs over time.
