About this system
The MrCool VersaPro 5-ton 13.4 SEER2 gas/electric package unit is a self-contained rooftop or slab-mount system that combines a gas furnace and an electric air conditioner in one cabinet. At 110,000 BTU of gas heat with an 81% AFUE rating, it is built for larger homes or light commercial spaces in climates where winter heating loads are real but not extreme. The multi-positional design allows installation in horizontal or downflow configurations, giving contractors and capable homeowners some flexibility in how it connects to existing ductwork. It runs on R-454B, a lower-global-warming-potential refrigerant that meets current EPA regulations and will remain serviceable as older refrigerants are phased out.
This unit sits at the entry tier of efficiency for package systems. A 13.4 SEER2 rating clears the federal minimum for most U.S. regions but does not promise low utility bills the way a 16+ SEER2 system would. The 81% AFUE furnace section is similarly baseline, meaning roughly 19 cents of every dollar spent on gas escapes as exhaust heat. Buyers coming from an aging 10 SEER system will see a meaningful improvement, but those prioritizing long-term energy savings should weigh whether a higher-efficiency unit pays back the price gap over time. MrCool positions this in the value tier, and the appeal is upfront cost rather than operating economy.
The MrCool VersaPro 5-ton package unit offers a budget-accessible entry point for large-home or light-commercial replacements, and its R-454B refrigerant keeps it future-compliant. The efficiency numbers are baseline, not impressive, and MrCool's thin service network and documentation-heavy warranty process are real concerns for a complex ducted system where professional support matters more than it does on a simple mini-split.
Overall score is the average of the five ratings above.
What we like
- Upfront cost is lower than comparable Carrier, Trane, or Lennox package units at similar efficiency
- R-454B refrigerant is compliant with current and near-future EPA regulations
- Multi-positional cabinet adds flexibility for retrofit installations with existing ductwork
- 5th-generation MrCool platform has improved meaningfully in reliability over 3rd and 4th gen
- All-in-one package reduces installation labor compared to a split system requiring line-set work
Trade-offs
- 81% AFUE gas heat is among the lowest efficiency ratings still sold; operating costs will reflect that
- 13.4 SEER2 is the regulatory floor, not a meaningful efficiency advantage over competing entry-level units
- MrCool's warranty process is documented to be claim-heavy and owners report coverage denials over paperwork issues
- Few local HVAC technicians stock MrCool parts or have factory training, making service calls harder to arrange
What homeowners and pros say about MRCOOL
Among homeowners who have purchased MrCool ducted and package systems, the conversation often splits along the same line: those who got a smooth installation and a working system are pleased with the savings versus name-brand alternatives, while those who hit early failures describe a frustrating experience trying to get warranty help. Home Depot owner reviews on MrCool’s popular DIY mini-split lines average around 4.5 out of 5, with easy self-install as the most cited reason for satisfaction. The VersaPro package unit is a different product category that requires a licensed installer, so the DIY praise does not transfer directly. On this type of system, the feedback that surfaces most often involves MrCool’s documentation-heavy warranty process, with owners reporting that the company scrutinizes claims closely and sometimes denies coverage on procedural grounds.
HVAC professionals have a more pointed view. Many independent technicians are reluctant to service MrCool equipment because factory support and parts sourcing can be inconsistent, and when a repair falls back on the homeowner or a reluctant third-party tech, costs rise quickly. MrCool’s 5th-generation platform is meaningfully better than the 3rd and 4th generation, which saw failure rates close to 25 percent in the first two years, and roughly 85 percent of 5th-gen units are reported to run reliably past year one. Even so, documented failure modes for the broader MrCool line include loose couplings near the air handler, early compressor issues, and refrigerant-side problems that require a certified technician to resolve. For a rooftop package unit serving a large home, buyers should weigh whether the upfront savings offset the cost and difficulty of a repair scenario where local service is not readily available.

What it costs to run
At 13.4 SEER2, cooling this 5-ton system for a typical 1200-hour cooling season at the U.S. average electricity rate of $0.17/kWh works out to roughly $913 per year in cooling, about $0 less per year than a minimum-efficiency 13.4 SEER2 unit of the same size. Your real cost depends on your climate and local rate.
Method: (60,000 BTU/hr ÷ 13.4 SEER2) × 1200 hours ÷ 1000 × $0.17/kWh. Rate source: U.S. EIA average; cooling hours: moderate-climate estimate.

Questions about this system
Can a homeowner install this package unit without a licensed HVAC contractor?
Unlike MrCool's pre-charged mini-split line, this gas/electric package unit involves natural gas piping and high-voltage electrical work that require licensed contractors in virtually every U.S. jurisdiction. Attempting a DIY install will also void most warranties and may violate local building codes. Budget for professional installation.
Is 81% AFUE gas heat going to cost noticeably more to run than a higher-efficiency furnace section?
Yes, in colder climates the difference is real. A 96% AFUE furnace converts nearly all fuel to heat, while this unit loses about 19% up the flue. In a mild-winter region where heating hours are low, the gap is modest. In a cold climate with high annual heating demand, the efficiency shortfall adds up on monthly gas bills.
What happens if the unit needs a repair and no local tech will service MrCool?
This is a genuine risk with MrCool. The brand has limited authorized service networks compared to Carrier or Trane, and many independent HVAC shops are reluctant to work on it or source parts. Owners often end up troubleshooting via MrCool's email support, which draws complaints about long response times. Confirm parts availability and local willingness to service before purchasing.
What does R-454B refrigerant mean for long-term serviceability?
R-454B is an A2L low-GWP refrigerant that meets current EPA requirements and is designed to remain available as R-410A is phased down. It does require technicians to use equipment rated for mildly flammable refrigerants, which most modern HVAC recovery and charging tools now support. Serviceability should not be a concern going forward.
How does MrCool's warranty on this package unit work, and what are the catch points?
MrCool offers a limited warranty on the VersaPro series, but the brand is widely documented for requiring thorough paperwork and registered proof-of-purchase, and owners report that claims are sometimes denied on technical grounds. Keeping all installation records, registration confirmation, and service documentation from day one is essential. Read the warranty terms carefully before purchase so the requirements are clear upfront.
