Check a quote

Certified capacity belongs to a pairing of an outdoor unit with an indoor one. The pairing installed in your house is the one that decides the real number, which is why this check asks for both.

1. Did you run a Manual J load calculation, and what load did it give?
2. Is the indoor unit on this quote the one on the AHRI certificate?
3. Is the AHRI certificate number on the quote, and can I have a copy?
4. What design temperature did you size to, and what heat loss did you calculate?
5. What covers the load below the design temperature: backup heat, or the heat pump alone?
6. What is the warranty on parts, on the compressor, and on labor?
7. Does the warranty require registration, and by when?
8. Which rebate or program are you applying for, and who files it?
9. What is the line-set length, and does it need changing?
10. Does the electrical service need work?

About the figures

The 47°F test depends on compressor staging: normal speed for variable-speed units, high stage for two-stage units, and the single operating speed for single-stage units. The 17°F and 5°F figures use full-speed tests. The 5°F-to-47°F ratio can compare tests at different compressor speeds.

The same figures are on each model's own page. Browse them at every certified model, A to Z, or search at Find a model.
