Missouri Licensing and Efficiency Rules
Missouri 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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Missouri the company should carry a state license or registration. Ask for both.
Before You Hire
- Ask for the per-pound refrigerant price before any work starts.
- Swap the air filter and check the breaker before you call anyone.
- If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
