Shopping for a new AC? Start with the rating of the actual system in your quote. SEER2 is a seasonal cooling efficiency rating. It is useful for comparing equipment, but it does not predict your electricity bill.
SEER and SEER2 are different comparisons
The updated SEER2 test procedure changed how equipment is tested. Avoid comparing a SEER number directly with a SEER2 number as though the methods were identical. Ask your contractor to explain the ratings on both systems.
What SEER2 Minimum Applies In Texas?
Texas is in the Southeast region under the federal efficiency rules. For standard split-system central air conditioners installed from January 1, 2023, the minimum is 14.3 SEER2 when certified cooling capacity is below 45,000 Btu/h, or 13.8 SEER2 at 45,000 Btu/h and above. The threshold uses certified capacity, so ask for the exact equipment rating rather than relying on a sales label such as “four ton.”
Split-system heat pumps have separate national requirements: equipment manufactured from January 1, 2023 must meet at least 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. Specialized equipment classes can have different requirements. Ask Prime to identify the applicable equipment class and show the rating and compliance evidence for the proposed installation. Read The Federal AC And Heat-Pump Efficiency Requirements.
These are minimum requirements, not a prediction of comfort or bills and not a reason to buy a particular model. Keep the matched indoor and outdoor equipment record with your quote and compare the full installation scope.
Ask about the matched system
The outdoor unit is only part of the installation. Ask which indoor equipment is included and request the efficiency rating for that specific combination. Confirm the requirements that apply to the equipment and the installation location. Manufacturer guide to regional efficiency standards.
Keep The Rating With The Written Quote
Ask for the AHRI Certified Reference Number or Certificate of Performance for the exact indoor and outdoor equipment being proposed. Compare the model numbers and rating on that record with the quote. A product family’s advertised “up to” rating does not establish the rating of every configuration. Keep the record with your equipment paperwork; it is performance evidence, not a prediction of your household bills. Look Up Certified Equipment Performance In The AHRI Directory. Organize Equipment And Warranty Records.
Look beyond the equipment label
Ask how the proposed system fits your home’s airflow and comfort needs. Installation, ducts, weather, thermostat use and electricity rates all affect the result. Compare the complete installed price alongside estimated operating costs.
Bring these questions to your consultation
- Which equipment models are included?
- What rating applies to that matched system?
- What installation or duct changes are part of the quote?
- What warranty terms and payment options apply?
