What is the SEER2 rating of the AI AIR CONDITIONING AO29-24N1-M1H?

The AI AIR CONDITIONING AO29-24N1-M1H is rated at up to 21.5 SEER2 and 13.0 EER2 for cooling and up to 11.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the AI AIR CONDITIONING AO29-24N1-M1H good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 25,000 BTU/h at 5°F with a COP of 2.21, so it is still 2.2 times as efficient as electric resistance heat at that temperature.

How much does the AI AIR CONDITIONING AO29-24N1-M1H cost to run per year?

At its rated efficiency it costs about $527-$1,568 a year in electricity in large U.S. cities, depending on climate and local rates - for example $672 in Phoenix and $1,327 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the AI AIR CONDITIONING AO29-24N1-M1H the same as the CanAir C28SCH24H21?

Yes, as far as the certified ratings go. ENERGY STAR lists 6 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 AI AIR CONDITIONING AO29-24N1-M1H?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses AW29-24N1-M1.

What refrigerant does the AI AIR CONDITIONING AO29-24N1-M1H use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

24,000 BTU mini-split heat pump · AW Series

AI AIR CONDITIONING AO29-24N1-M1H

Below average cooling efficiency and very good heating efficiency for a 24,000 BTU mini-split heat pump, and certified for cold climates.

Ranks #232 of 430 24,000 BTU mini-splits for cooling efficiency, and costs about $640 a year to run in a mixed climate like Atlanta.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 25,000 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 82% of mini-splits.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

Cooling cost matters most - its SEER2 is below average for mini-splits.
You want the newest refrigerant - it uses R-410A, which is being phased down.
