What is the SEER2 rating of the NOVAIR LEA30CEN36-O?

The NOVAIR LEA30CEN36-O is rated at up to 17.2 SEER2 and 12.0 EER2 for cooling and up to 10.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 6 certified matchups SEER2 ranges from 15.3-17.2.

Is the NOVAIR LEA30CEN36-O good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 33,200 BTU/h at 5°F with a COP of 1.97, so it is still 2.0 times as efficient as electric resistance heat at that temperature.

How much does the NOVAIR LEA30CEN36-O cost to run per year?

At its rated efficiency it costs about $738-$1,838 a year in electricity in large U.S. cities, depending on climate and local rates - for example $957 in Phoenix and $1,500 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Which indoor units work with the NOVAIR LEA30CEN36-O?

ENERGY STAR lists 6 certified combinations for this outdoor unit. The highest-rated ones use LEA30HH-CEN-I, LEA30CEN36-I, LEA-30/36ACOIL17.5*21*24.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
