No listed product is rated at 1 ton: the smallest options are 2-ton systems. The ACiQ 2-ton heat pump is the closest match for buyers who need electric heating and cooling, while the 2-ton gas package is an option for homes with natural gas. These are packaged horizontal units, but the supplied product information does not confirm rooftop-mounting details. Have an HVAC professional verify capacity, configuration, and installation requirements before choosing.
| Product | Capacity | Heating Type | Best Fit |
|---|---|---|---|
| ACiQ 2 Ton Heat Pump | 2 ton | Heat pump; 7.5kW backup heat kit | Electric heating and cooling |
| ACiQ 2 Ton Gas Package | 2 ton | Natural gas | Buyers seeking gas heat |
| ACiQ 2.5 Ton Heat Pump | 2.5 ton | Heat pump | Higher capacity than 2 tons |
| ACiQ 3.5 Ton Heat Pump | 3.5 ton | Heat pump | Substantially larger loads |
| ACiQ 4 Ton Heat Pump | 4 ton | Heat pump; 15kW backup heat kit | Large heating and cooling needs |
ACiQ 2 Ton Heat Pump With Backup Heat
Best for: Buyers who have confirmed that a 2-ton system is appropriate and want a packaged unit offering both heating and cooling. This model is rated at 24,000 BTU and includes a 7.5kW backup heat kit and thermostat, according to its listing.
The product features specify a 13.4 SEER2 rating, R32 refrigerant, and a horizontal configuration. Its heat-pump design provides heating and cooling in one system, with electric backup heat included in the package.
Limitation: It is twice the nominal capacity of a 1-ton unit. Do not treat it as a direct substitute without a professional load calculation and installation review.
ACiQ 2 Ton Gas Package Unit
Best for: Buyers whose site has natural-gas service and who prefer a gas-heating packaged system with air conditioning. The product name identifies a 2-ton cooling capacity and an 81% AFUE natural-gas heating system.
Like the heat-pump option, this is a horizontal packaged unit with a listed 13.4 SEER2 rating and R32 refrigerant. Its gas heat differentiates it from the electric heat-pump models, so fuel availability and installer requirements are important selection factors.
Limitation: The 2-ton capacity does not match a 1-ton requirement. The supplied information does not specify rooftop mounting hardware or confirm that this configuration suits a particular building.
ACiQ 2.5 Ton Heat Pump
Best for: Buyers whose calculated heating and cooling load calls for more capacity than 2 tons. This 30,000-BTU heat pump combines heating and cooling in one packaged system and includes an install kit, as stated in the product name.
Listed features include a 13.4 SEER2 rating, R32 refrigerant, horizontal configuration, and low-sound operation. Choose this over the 2-ton models only when a qualified load assessment supports the larger size.
Limitation: At 2.5 tons, it is further from a 1-ton target. Its listing does not identify a backup heat kit or thermostat as included.
ACiQ 3.5 Ton Heat Pump
Best for: Buyers with a substantially larger calculated load who want a packaged heat pump. The model is rated at 42,000 BTU and is described as providing heating and cooling for residential or commercial applications.
The listed efficiency and refrigerant details are 13.4 SEER2 and R32. An install kit is included in the product name. It may be a better fit than the 2- or 2.5-ton models only when the building’s load and equipment specifications call for 3.5 tons.
Limitation: This is not a close capacity match for a 1-ton system. The listed features do not specify a backup heat kit.
ACiQ 4 Ton Heat Pump With Backup Heat
Best for: Buyers who need a larger-capacity heat pump and specifically want a backup heat kit included. The product is rated at 48,000 BTU and names a 15kW backup heat kit and install kit.
It combines heating and cooling and lists 13.4 SEER2, R32 refrigerant, and a horizontal configuration. Compared with the smaller products here, it offers the highest nominal capacity in this selection.
Limitation: A 4-ton unit is not an appropriate stand-in for a 1-ton system simply because it is available. Oversizing can create comfort and operating problems; professional sizing is essential.
Buying Guide: How to Choose a Rooftop HVAC Unit
Is a 2-ton unit suitable for a 1-ton replacement?
Not automatically. A ton is a measure of cooling capacity, and a 2-ton unit has twice the nominal capacity of a 1-ton unit. The smallest products in this selection are 2 tons, so buyers needing exactly 1 ton should seek a correctly sized model rather than assume a larger unit will work.
How should you compare heat pump and gas package units?
Heat pumps provide both heating and cooling through an electric system; some listings include electric backup heat. The gas package option uses natural gas for heating. Compare the available fuel, existing site setup, local climate, and installer guidance. The supplied listings do not provide enough information to determine which system is best for a specific property.
What should you confirm before rooftop installation?
Ask an HVAC professional to verify the building load, required capacity, horizontal configuration, duct connections, electrical and fuel needs, clearances, and rooftop support. The products are described as packaged horizontal units, but that description alone does not establish rooftop suitability or confirm that all mounting components are included.
What do the efficiency and refrigerant details tell you?
The heat-pump listings specify 13.4 SEER2 and R32 refrigerant. These details help compare listed equipment characteristics, but they do not establish expected utility costs or performance in a particular home. The gas-unit listing also states 81% AFUE; confirm model specifications and local requirements with the installer.
Frequently Asked Questions
Are any of these products 1-ton rooftop units?
No. The smallest listed products are 2-ton packaged units, and the supplied details do not confirm rooftop mounting.
Which listed product is closest to a 1-ton system?
The ACiQ 2-ton heat pump and 2-ton gas package are the closest by capacity, but both are still rated at twice 1 ton.
Does a packaged unit include everything needed for rooftop installation?
The product information mentions install kits for some models, but it does not establish that rooftop curbs, supports, or every installation component are included. Confirm the exact contents before purchase.
Should I choose a larger unit to improve cooling?
No. Choose capacity based on a professional load calculation. A larger unit is not necessarily more comfortable or efficient when it is oversized for the building.
