Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Friedrich FRP15AZ18AJ2N at the three ENERGY STAR test temperatures (cooling capacity is 17,100 BTU/h for reference).
Retention at 17°F: 72% · at 5°F: 56%. Learn how to use these numbers in our cold-climate guide.

Same equipment sold under other brands
These listings share the same certifying manufacturer (Rheem Sales Company, Inc.) and identical certified capacities and efficiency ratings, so they are almost certainly the same hardware with a different badge. If you get quotes for any of them, you are comparing installation price and warranty, not equipment. How rebadging works.

Frequently asked questions
How much does the Friedrich FRP15AZ18AJ2N cost to run per year?
At the U.S. average residential electricity price of 18.16¢/kWh and typical national heating and cooling hours, we estimate about $838 per year ($613 heating, $225 cooling). It ranges from about $480 in Louisiana to $1,907 in Maine.
Does the Friedrich FRP15AZ18AJ2N work in cold weather?
It is not ENERGY STAR cold-climate certified. It delivers 9,500 BTU/h at 5°F (56% of its 47°F capacity), so in very cold climates expect more reliance on backup heat.
What size is the Friedrich FRP15AZ18AJ2N?
It is rated at 17,100 BTU/h of cooling, roughly 1.5 tons, and 17,100 BTU/h of heating at 47°F. Proper sizing should be confirmed with a Manual J load calculation.
Is the Friedrich FRP15AZ18AJ2N the same as the Friedrich FWP15AZ18AJ2N?
Very likely. Both are certified by Rheem Sales Company, Inc. with identical capacities and efficiency ratings in the ENERGY STAR database, which indicates the same equipment sold under different brands.
