Local context for Richardson

  • Exential U S Inc is one of 32 businesses we list for ac services in Richardson (53 HVAC businesses in total).

Buying a new AC or heat pump in California

  • California is in the DOE Southwest region: new central air conditioners installed since January 1, 2023 must meet at least 14.3 SEER2 and 11.7 EER2 (13.8 SEER2 and 11.2 EER2 for systems 45,000 BTU/h and larger). Heat pumps must meet 14.3 SEER2 and 7.5 HSPF2 nationwide.
  • Since 2025, new systems are built for lower-impact refrigerants such as R-454B or R-32. Ask which refrigerant a quoted system uses and for its AHRI certificate number, which confirms the matched system’s rated efficiency.
