What is the SEER2 rating of the Kaden KOVH-18BAM152L?

The Kaden KOVH-18BAM152L is rated at up to 15.2 SEER2 and 12.0 EER2 for cooling and up to 7.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the Kaden KOVH-18BAM152L good for cold climates?

It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 1.5-ton model.

How much does the Kaden KOVH-18BAM152L cost to run per year?

At its rated efficiency it costs about $555-$1,418 a year in electricity in large U.S. cities, depending on climate and local rates - for example $675 in Phoenix and $1,177 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 Kaden KOVH-18BAM152L?

ENERGY STAR lists 6 certified combinations for this outdoor unit. The highest-rated ones use KVWH18TABE, KVWH24TABE, KMAH36TBBE.

1.5-ton central heat pump · KOVH152

Kaden KOVH-18BAM152L

Below average cooling and heating efficiency for a 1.5-ton central heat pump, but not rated for cold climates.

Ranks #167 of 170 1.5 ton central heat pumps for cooling efficiency, and costs about $600 a year to run in a mixed climate like Atlanta.

A good fit if…

You want a certified 1.5-ton central heat pump at a typical efficiency level.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
Cooling cost matters most - its SEER2 is below average for central heat pumps.
You mainly need heat - its HSPF2 is below average for central heat pumps.
Comfort and noise matter - a single-stage compressor runs only full-on or off.

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.
