Boonville at a glance
Boonville is the Cooper County seat, across the Missouri River on I-70, about 23 miles west of central Columbia. It is a city of about 7,689 people with an older housing stock: the median home was built in 1965, and 72% of homes date from before 1980. About 48% of occupied homes heat with electricity (Census ACS), so a heat pump is a common replacement here.

The houses and their equipment
Census ACS 2020-2024 counts roughly 4,628 housing units in ZIP 65233, and puts the median year built at 1973. Older homes are the norm: 60% were built before 1980. In houses that age the ducts were frequently laid out for whatever heated the place first, sometimes retrofitted into a house that began with radiators or a floor furnace, so the ductwork can limit comfort as much as the condenser does. Duct repair.
Electricity is the main heat source in 49% of occupied homes (Census ACS). In those houses, a heat pump is the usual replacement, because a single outdoor unit covers July cooling and the bulk of January heating. Heat pumps in Columbia.
Weather here tracks the airport south of Columbia closely. It averaged 42.7 days a year at 90°F or more over 2016-2025, logged 44 so far in 2026, and sees around 9.8 nights a year at 10°F or lower. Plan on a cooling season that runs hard from June into September, then a real heating season after it.

Boonville questions
Is every address in Boonville covered?
Yes, ZIP 65233 included. When the HVAC company phones, it double-checks that your road falls inside its territory.
What licensing applies in Boonville?
Missouri doesn't license HVAC contractors statewide, so outside the city of Columbia it comes down to local rules. Ask whether a town or county permit is needed and request a certificate of insurance. EPA Section 608 certification is required for refrigerant work no matter where you live.
Will I know the cost before the work starts?
Yes. After diagnosing it, the technician quotes the repair and waits for your answer. When booking, ask what the visit or diagnostic charge will be.
