Reich A/C Provides quality Heating and Air Conditioning Service in the Greater Houston area
Packaged AC Units


Packaged systems offer a more minimalist approach to heating and cooling. The system contains the same components as your typical split-system—the evaporator, condenser, compressor and more—all working together in one space-saving unit. Packaged units are typically installed outdoors at ground level or on the roof, making them versatile for both horizontal or down-flow designs.

Efficiency Ratings
SEER – Energy Efficiency Ratio MBH per kW
SEER – Seasonal EER MBTU per kWh
IPLV – Integrated Part-load Value MBH per kW
Energy Star light commercial HVAC equipment uses 7–10% less energy than standard equipment.
Energy Star package units can save $3 to $4 per square foot over the life of the equipment.
 Energy Star efficiency rating

  • Units rated at 65,000 to 135,000 Btuh
  • 11.0 EER or higher -and- 11.4 IPLV or higher
  • Units rated at 135,000 to 250,000 Btuh
  • 10.8 EER or higher -and- 11.2 IPLV or higher
  • Three-phase equipment rated below 65,000 Btuh
  • SEER 13.0 or higher

Air conditioner EER ratings are measured at outdoor temperature of 95°F, indoor 80ºF dB
67ºF WB or 50% Relative Humidity.
IPLV takes into account the higher efficiency of air conditioning units at part load. IPLV is
measured using ARI Standard weightings and provides more of an “apples to apples”
comparison than EER alone.
SEER was intended to rate efficiency over an entire cooling season, not a single outdoor
temperature. In theory, SEER is calculated by total amount of cooling (Btu) over the entire
season divided by the total Watt-hours it will consume. SEER is used only for units 5-tons
and less.
