Model
Frigidaire LGHX2636T*
Rank #906 means 905 of the 1,000 refrigerator models we track cost less to run each year; the 73rd efficiency percentile means it uses less energy for its size than 73% of those models.
What does the Frigidaire LGHX2636T* cost to run per year?
Among the 1,000 refrigerator models we track, the Frigidaire LGHX2636T*'s $120/yr running cost ranks it #906, in the pricier fifth of the class. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $132/yr to run, a saving of roughly $12 a year. Its size-adjusted efficiency percentile of 73 is comfortably above the class median. This class has no published efficiency-factor figure beyond annual kWh itself, so at 25.6 cu ft (the class spans 1.2 to 31.7), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Whirlpool WRFF3336SB at $120/yr runs a little cheaper and the Crosley Professional ZRSEH268A* at $120/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A refrigerator typically stays in service for somewhere around 12 years; over that span, the Frigidaire LGHX2636T*'s $120/yr adds up to roughly $1440 in electricity alone, before purchase price or repairs.
By the numbers
The Frigidaire LGHX2636T* normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $120/yr, here is what the Frigidaire LGHX2636T* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Frigidaire LGHX2636T* costs about $1200. That is roughly $120 less than a standard model in its class, which would run closer to $1320 over the same ten years.
How the Frigidaire LGHX2636T* compares
The refrigerator class we track runs from $8 to $149 a year. At $120/yr, it runs about $56 a year above the class median of $64, and it is about $112 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $132/yr, the Frigidaire LGHX2636T* uses 10% less energy.
What drives its running cost
At 25.6 cu ft, the Frigidaire LGHX2636T* is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, among refrigerator models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal.
- Interior volume. More cubic feet of cold air to maintain generally means a bigger compressor and a higher running-cost figure, even among efficient models.
- Counter depth vs standard depth. Standard-depth models generally offer more interior volume per unit of width than counter-depth models, a tradeoff between built-in looks and cubic feet.
- Compressor technology. How a compressor cycles, full on/off versus a variable-speed inverter design, is one of the biggest hidden differences behind two fridges with similar cubic feet but different running costs.
- Placement and ventilation. Ventilation clearance around the back and top matters more than most owners expect; a fridge starved of airflow runs its compressor longer to hold the same temperature.
Common questions
Is the Frigidaire LGHX2636T* cheap to run?
Its $120/yr running cost, rank #906 of 1,000, is above what most refrigerator models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Frigidaire LGHX2636T* cost per month?
About $9.99 a month, which is the $120 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 646 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $120 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Frigidaire LGHX2636T* for its size?
73rd percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
