What is the SEER2 rating of the Concord 4HP17L36P-**A?

The Concord 4HP17L36P-**A is rated at up to 16.8 SEER2 and 14.0 EER2 for cooling and up to 8.7 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 1578 certified matchups SEER2 ranges from 15.2-16.8.

Is the Concord 4HP17L36P-**A 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 3-ton model.

How much does the Concord 4HP17L36P-**A cost to run per year?

At its rated efficiency it costs about $998-$2,485 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,205 in Phoenix and $2,057 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Which indoor units work with the Concord 4HP17L36P-**A?

ENERGY STAR lists 1578 certified combinations for this outdoor unit. The highest-rated ones use 7EC48CX-0*+TDR, 7EH42CX-0*+TDR, EAD4X-48C+TDR.

What refrigerant does the Concord 4HP17L36P-**A 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…

You want a choice of indoor units - 1,578 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
You want the newest refrigerant - it uses R-410A, which is being phased down.
Comfort and noise matter - a single-stage compressor runs only full-on or off.
