What is the SEER2 rating of the Friedrich FRP15AZ18AJ2N?

The Friedrich FRP15AZ18AJ2N is rated at up to 16.0 SEER2 and 11.7 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 42 certified matchups SEER2 ranges from 15.2-16.0.

Is the Friedrich FRP15AZ18AJ2N 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 Friedrich FRP15AZ18AJ2N cost to run per year?

At its rated efficiency it costs about $502-$1,335 a year in electricity in large U.S. cities, depending on climate and local rates - for example $618 in Phoenix and $1,115 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Friedrich FRP15AZ18AJ2N the same as the Friedrich FWP15AZ18AJ2N?

Yes, as far as the certified ratings go. ENERGY STAR lists both 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 Friedrich FRP15AZ18AJ2N?

ENERGY STAR lists 42 certified combinations for this outdoor unit. The highest-rated ones use FRH2VZ2417STANN, TCFZ2417STANM, RCFZ2417STANM.

What refrigerant does the Friedrich FRP15AZ18AJ2N 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.

1.5-ton central heat pump · F-SERIES PLUS

Friedrich FRP15AZ18AJ2N

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

Ranks #109 of 170 1.5 ton central heat pumps for cooling efficiency, and costs about $559 a year to run in a mixed climate like Atlanta.

A good fit if…

You want a choice of indoor units - 42 certified pairings.

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.
You want the newest refrigerant - it uses R-410A, which is being phased down.
