What is the SEER2 rating of the Lennox VPC048H5M-3P?

The Lennox VPC048H5M-3P is rated at up to 20.0 SEER2 and 11.7 EER2 for cooling and up to 10.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 6 certified matchups SEER2 ranges from 17.6-20.0.

Is the Lennox VPC048H5M-3P good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 40,000 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.

How much does the Lennox VPC048H5M-3P cost to run per year?

At its rated efficiency it costs about $1,118-$3,100 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,393 in Phoenix and $2,602 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

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.
