About this system
The ACiQ AGAGC9PNS01E is a liquid propane (LP) conversion kit designed to adapt compatible ACiQ gas furnaces from natural gas to propane operation. If your home runs on a propane tank rather than a utility gas line, this kit provides the orifice set, pressure regulator components, and hardware needed to make that switch safely and correctly. It is not a standalone appliance; it is a furnace accessory that must be installed by a licensed HVAC technician or gas fitter who can verify manifold pressure, combustion, and leak integrity after conversion.
Propane conversions are a common requirement in rural areas where natural gas service is unavailable, and using the manufacturer-supplied kit rather than a generic aftermarket part ensures that the orifice sizing, gas valve calibration, and safety interlocks are matched to the specific furnace model. The AGAGC9PNS01E is sold as part of ACiQ’s direct-to-consumer model, which keeps the price below what you would typically pay through a dealer-stocked kit from a name brand. That said, the stakes on a gas conversion are high enough that correct installation and a post-conversion combustion check are non-negotiable regardless of which brand kit you use.
The AGAGC9PNS01E is a straightforward, purpose-built conversion kit that does what conversion kits are supposed to do: match orifice sizing and gas valve settings to propane for a specific furnace line. The value proposition is real because ACiQ sells direct and the kit price reflects that. The honest caution is that ACiQ is a newer brand with limited long-term service data, and because the underlying manufacturer is undisclosed, sourcing replacement parts or cross-referencing service bulletins is harder than with a Carrier or Trane kit.
Overall score is the average of the five ratings above.
What we like
- Manufacturer-matched orifice sizing reduces the risk of mismatched aftermarket components
- Direct-to-consumer pricing keeps kit cost lower than dealer-bundled equivalents from name brands
- Supports propane use in rural or off-grid homes that cannot access natural gas lines
- ACiQ's customer support has drawn consistently positive feedback in early owner reviews
- Buying the OEM kit alongside the furnace simplifies parts accountability and warranty claims
Trade-offs
- Undisclosed manufacturer makes cross-referencing parts, service bulletins, and tech specs harder for contractors unfamiliar with the brand
- ACiQ is relatively new and lacks the long-term reliability data that Consumer Reports or independent studies provide for established brands
- No dealer network means finding a contractor experienced with ACiQ equipment requires extra vetting on the buyer's side
- A gas conversion kit has zero value if installed incorrectly, and the direct-sale model means there is no dealer tech support at the point of installation
What homeowners and pros say about ACiQ
Early ACiQ owners who have gone through the LP conversion process report that the kit components are well-matched to their furnaces and that ACiQ’s support team was responsive when questions came up during installation. These accounts are encouraging but represent a small and relatively recent sample. Consumer Reports has not yet ranked ACiQ due to insufficient long-term data, so there is no independent reliability score to point to. The absence of a disclosed manufacturer is a recurring friction point specifically mentioned by HVAC contractors on trade forums, because they cannot easily pull cross-reference documentation or confirm parts interchangeability the way they can with a Carrier or Trane unit. That issue is less acute for a conversion kit than for a compressor or heat exchanger, but it is still part of the ownership picture buyers should understand going in.
The failure modes most worth watching in the broader ACiQ line, which could indirectly affect a conversion kit experience, center on the fact that long-term component behavior is simply unknown. With established brands, technicians know from years of field data which capacitors tend to fail early, whether coil leak rates are above average, and what compressor lifespan looks like across climate zones. None of that independent pattern data exists yet for ACiQ. For a conversion kit specifically, the more immediate risk is not product failure but incorrect installation, and because ACiQ relies on independent contractors rather than a proprietary dealer network, the quality of the installation experience will vary more than it would with a brand that trains and certifies its own dealer technicians.

Questions about this system
Can I install this LP conversion kit myself, or does it require a licensed technician?
This work must be performed by a licensed HVAC technician or certified gas fitter in virtually every jurisdiction. A propane conversion involves adjusting gas valve pressure and swapping orifices; an improper conversion can cause incomplete combustion, carbon monoxide risk, or a gas leak. Professional installation is not optional here.
Will using this kit affect my ACiQ furnace warranty?
Using the manufacturer-supplied OEM conversion kit, rather than a generic aftermarket part, is the safest path for preserving your warranty coverage. That said, you should confirm with ACiQ directly that professional installation of this specific kit does not void any portion of the 12-year warranty before proceeding.
Is this kit compatible with all ACiQ gas furnace models, or only specific ones?
The AGAGC9PNS01E is designed for specific ACiQ furnace models, so you need to verify compatibility with your furnace's model number before purchasing. Using a conversion kit on an incompatible furnace model can result in incorrect orifice sizing and unsafe operation.
Since ACiQ's manufacturer is not publicly disclosed, will my contractor be able to find parts or service information?
This is a real concern. Because the underlying manufacturer is not confirmed, contractors cannot easily cross-reference ACiQ parts with known ICP, Carrier, or other family equivalents. ACiQ's direct support line is the primary resource, which works adequately during business hours but is a thinner safety net than a full dealer network.
What does the post-conversion combustion check involve, and why does it matter for propane?
After conversion, a technician should measure manifold gas pressure with a manometer, verify burner flame appearance, and check for carbon monoxide in the flue. Propane burns at a different pressure and stoichiometry than natural gas, so confirming these values are within specification is the step that confirms the conversion was done correctly and safely.
