Iowa Licensing and Efficiency Rules
Iowa falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Iowa license or registration number before the visit.
Before You Hire
- Ask what the emergency fee is before the truck is sent.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Maintenance plans often put members first in line for emergency calls.
