Is a mini split worth it in El Paso?
Short answer: Yes, for most El Paso homes. El Paso’s desert climate is different from the rest of Texas: summers are hot and dry, with a 99.1°F design high, and winter nights freeze, with a 25.7°F design low. A mini split works as the air conditioner in summer and the heater in winter: El Paso logs about as many heating hours (1,559) as cooling hours (1,524) a year (ENERGY STAR). Every MRCOOL DIY series keeps heating far below El Paso’s coldest night of the February 2021 storm, 14°F. Size each room with the standard chart and go one size up for west-facing or top-floor rooms.
El Paso compared with the rest of Texas
El Paso sits in the desert at the far west of Texas. It needs real winter heating, which Houston barely does, and its summer air is dry instead of humid.
| City (climate zone) | Summer high | Winter low | Feb 2021 low | Cooling hours | Heating hours |
|---|---|---|---|---|---|
| El Paso (3B) | 99.1°F | 25.7°F | 14°F | 1,524 | 1,559 |
| Houston (2A) | 95.7°F | 31.4°F | 13°F | 2,209 | 1,127 |

Cooling in dry desert heat
In El Paso’s dry heat a mini split does mostly cooling and little drying. The inverter slows down instead of switching off, so it holds the temperature on long afternoons with less power.
Heating on El Paso winter nights
Yes, with room to spare. El Paso’s coldest night of the February 2021 storm was 14°F, far above the −12°F and −13°F the MRCOOL DIY series heat down to.
