South Dakota Licensing and Efficiency Rules
South Dakota 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 South Dakota the company should carry a state license or registration. Ask for both.
Before You Hire
- Book maintenance twice a year, once before summer and once before winter.
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.

Heat Pump Repair Questions from Brookings Homeowners
What does heat pump repair cost in Brookings?
Most bills land between $200 and $960, including the service call. A typical visit is about $620. Night and weekend calls cost more.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
