About this system
The Daikin 5-ton gas/electric commercial package unit delivers 140,000 BTU of heating at 81% AFUE alongside 5 tons of cooling rated at 13.7 SEER2. As a rooftop or ground-mount package unit, both the heating and cooling components live in a single cabinet, making it a common choice for light commercial buildings, large retail spaces, and oversized residential applications where a split system would be impractical or where interior mechanical space is limited. R-32 refrigerant gives this unit a lower global warming potential than the R-410A it replaces, and it is the direction the industry is moving for new equipment.
The single-stage operation means the compressor and gas valve run at full capacity whenever the system is on, which is efficient enough for spaces with steady, predictable loads but can result in short-cycling and humidity control challenges in buildings with highly variable occupancy or large glass areas. At 81% AFUE, the gas furnace section falls into the standard-efficiency tier rather than high-efficiency, meaning roughly 19 cents of every heating dollar exits as flue gas. For climates where heating is secondary to cooling, that trade-off is often acceptable. Buyers in cold-dominant climates should weigh whether a higher-AFUE unit would close the price gap over a few heating seasons.
This Daikin package unit is a solidly built piece of commercial-grade equipment from the world's largest HVAC manufacturer, but its 81% AFUE heating efficiency and single-stage operation place it in the functional rather than high-performance tier. It suits buyers who prioritize Daikin's documented build durability and want a straightforward rooftop package format, provided they go in aware of the brand's parts-support shortcomings and the registration deadline for the warranty.
Overall score is the average of the five ratings above.
What we like
- Daikin's track record for robust construction and long service life, consistently recognized by Consumer Reports and HVAC professionals
- R-32 refrigerant is lower-GWP and increasingly the industry standard, reducing future refrigerant-related regulatory risk
- Single-cabinet package design simplifies installation and removes the need for indoor air handler space
- 12-year parts warranty is competitive in the commercial package segment when registration is completed on time
- Established commercial package platform with wide contractor familiarity for rooftop applications
Trade-offs
- 81% AFUE is a standard-efficiency furnace section; high-efficiency alternatives in this class reach 90%+ and reduce long-term gas costs
- Single-stage operation limits humidity control and can cause short-cycling in variable-load commercial spaces
- Daikin's parts availability and warranty handling draw consistent complaints, which matters more for a commercial unit that must stay online
- Electronic control board errors are the most frequently documented failure mode and can leave the unit unresponsive until a service call is completed
What homeowners and pros say about Daikin
Among HVAC professionals who work with commercial package equipment, Daikin’s build quality is generally well regarded. Consumer Reports and experienced installers consistently place Daikin among the longer-lasting brands in terms of equipment lifespan, and that reputation carries over to rooftop package units. The concern that comes up repeatedly in professional circles is not the hardware itself but what happens after something goes wrong: parts availability for Daikin commercial units can be slower than for Carrier or Trane, and Daikin’s own service infrastructure draws criticism. The PissedConsumer rating of roughly 1.4 out of 5 reflects a complaint-skewed channel dominated by service and pricing frustrations rather than early equipment failure, but the signal about support responsiveness is consistent enough to take seriously, especially for a commercial unit where downtime costs money.
The specific failure modes worth knowing before you buy this unit are electronic control and circuit board errors, which are the most common complaint and can leave the system unresponsive or stuck in an error-code loop until a technician can diagnose the board; compressor issues that develop as units age, sometimes losing cooling capacity gradually before failing; and increasing operational noise over time, particularly rattling or humming during startup and shutdown cycles. None of these are unique to Daikin, but the parts-and-service complaint pattern means resolution can take longer than it would with a brand that has deeper local parts distribution. Buyers who have a reliable commercial HVAC service contractor lined up before installation and who register the unit promptly to secure the 12-year parts warranty are in a much better position than those who treat service as an afterthought.

What it costs to run
At 13.7 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 $893 per year in cooling, about $20 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 ÷ 13.7 SEER2) × 1200 hours ÷ 1000 × $0.17/kWh. Rate source: U.S. EIA average; cooling hours: moderate-climate estimate.

Questions about this system
Does the 12-year parts warranty cover both the cooling and heating sections of this package unit?
Yes, Daikin's 12-year parts warranty applies to the entire unit, including the compressor, heat exchanger, and components, but it requires product registration within 60 days of installation. If registration is missed, the warranty defaults to a shorter base term, so scheduling registration immediately after startup is critical.
Is 81% AFUE enough for my climate, or should I be looking at a higher-efficiency unit?
In mild to moderate climates where heating accounts for a small portion of annual energy use, 81% AFUE is often acceptable and the upfront savings versus a 90%+ unit can outweigh the efficiency gap. In cold climates with long heating seasons, the 10-plus point AFUE difference can translate to meaningful annual gas cost increases, so it is worth running the numbers for your specific location.
What does single-stage operation mean for a space with fluctuating occupancy, like a retail store?
Single-stage means the system runs at 100% capacity or is off entirely, with no in-between. In spaces where the load varies significantly, such as a store that goes from packed to empty, this can cause the unit to short-cycle, which reduces humidity removal efficiency and can increase wear on the compressor over time. A two-stage or variable-capacity unit handles those loads more smoothly.
How serious are the electronic control board failures mentioned in Daikin reviews, and what should I watch for?
Circuit board and control errors are Daikin's most commonly documented failure mode across complaint channels. They can present as the unit becoming unresponsive, throwing error codes on the thermostat or unit display, or cycling on and off unexpectedly. Having a qualified commercial HVAC technician perform annual preventive maintenance and inspect control wiring is the best way to catch issues before they cause a full shutdown.
Why does this unit use R-32 instead of R-410A, and does that affect service costs?
R-32 has a lower global warming potential than R-410A and is the refrigerant Daikin and much of the industry is transitioning to ahead of regulatory phase-downs. Service costs for R-32 are broadly similar to R-410A at present, but technicians need R-32 specific handling certification because it is mildly flammable. Confirm your service contractor is certified for R-32 work before installation.
