What is the SEER2 rating of the Lennox ML15KSPV-030-230A?

The Lennox ML15KSPV-030-230A is rated at up to 16.7 SEER2 and 11.4 EER2 for cooling and up to 9.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 16 certified matchups SEER2 ranges from 15.2-16.7.

Is the Lennox ML15KSPV-030-230A 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 2.5-ton model.

How much does the Lennox ML15KSPV-030-230A cost to run per year?

At its rated efficiency it costs about $825-$2,089 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,001 in Phoenix and $1,733 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Lennox ML15KSPV-030-230A the same as the GE Appliances NS15H30HA5?

Yes, as far as the certified ratings go. ENERGY STAR lists 3 model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.

Which indoor units work with the Lennox ML15KSPV-030-230A?

ENERGY STAR lists 16 certified combinations for this outdoor unit. The highest-rated ones use CBK48MVT-030-230-, CBK48MVT-036-230-, CBK47UHET-030-230-.
