Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Ruud UP19AY48AJVC at the three ENERGY STAR test temperatures (cooling capacity is 45,500 BTU/h for reference).
Retention at 17°F: 95% · at 5°F: 92%. 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 Ruud UP19AY48AJVC 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 $1,827 per year ($1,322 heating, $505 cooling). It ranges from about $1,061 in Louisiana to $4,123 in Maine.
Does the Ruud UP19AY48AJVC work in cold weather?
It is not ENERGY STAR cold-climate certified. It delivers 42,000 BTU/h at 5°F (92% of its 47°F capacity), so in very cold climates expect more reliance on backup heat.
What size is the Ruud UP19AY48AJVC?
It is rated at 45,500 BTU/h of cooling, roughly 4 tons, and 45,500 BTU/h of heating at 47°F. Proper sizing should be confirmed with a Manual J load calculation.
Is the Ruud UP19AY48AJVC the same as the Friedrich FRP19AY48AJVC?
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.
