Columbia Housing Stock
Half the homes in Columbia were built before 1993 (Census ACS median), so the typical house is about 33 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Columbia has roughly 25,000 owner-occupied homes, or 49.4% of households. With a median household income of $64,488 and a median home value of $268,300, local labor rates come out near the national middle in our model.
Boone County had 7 hail days and 25 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.75 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.

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
- Maintenance plans often put members first in line for emergency calls.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Ask what the emergency fee is before the truck is sent.
