What is the SEER2 rating of the TRUST AIR CONDITIONERS AA36H/O44P?

The TRUST AIR CONDITIONERS AA36H/O44P is rated at up to 16.0 SEER2 and 10.0 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 2 certified matchups SEER2 ranges from 15.2-16.0.

Is the TRUST AIR CONDITIONERS AA36H/O44P good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 34,400 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 TRUST AIR CONDITIONERS AA36H/O44P cost to run per year?

At its rated efficiency it costs about $1,054-$2,584 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,267 in Phoenix and $2,134 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the TRUST AIR CONDITIONERS AA36H/O44P the same as the NOVAIR LEA36-EVOX-30-O?

Yes, as far as the certified ratings go. ENERGY STAR lists 5 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 TRUST AIR CONDITIONERS AA36H/O44P?

ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use AH36H/I44P, CX36M/W4T4.

What refrigerant does the TRUST AIR CONDITIONERS AA36H/O44P 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.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 34,400 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 84% of central heat pumps.
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 central heat pumps.
You want the newest refrigerant - it uses R-410A, which is being phased down.
