Columbia HVAC Co. provides heating and cooling service throughout Hallsville, MO (ZIP 65255) — the most gas-heated of the small towns we cover, at 63.9% natural gas, with not a single occupied home in town reporting propane. That makes Hallsville a furnace town in the literal sense, and different from rural Boone County a few miles in any direction. We answer 24 hours a day with no extra fee for nights or weekends, service all brands, and are family owned and operated.
Hallsville's Housing Stock and Heating Fuel Mix
Hallsville has a population of 1,614, a median home value of $214,800 and homeownership of 76.8% — the highest of any community we studied around Columbia. When three-quarters of a town owns its homes, HVAC decisions get made on a ten- to twenty-year horizon rather than on whatever gets you through the winter.
The median Hallsville home was built in 1997, but that hides a split: 46.3% was built in 2000 or later while 33.0% predates 1980. We are effectively working on two towns — newer homes reaching their first equipment replacement, and older homes on their second or third system inside ductwork sized for a very different furnace.
| Heating fuel in Hallsville | Share of occupied homes |
|---|---|
| Natural gas | 63.9% |
| Electricity | 35.6% |
| LP / bottled propane | 0% |
That zero is worth pausing on. Across Boone County outside Columbia, propane heats roughly 17.8% of occupied homes — about eleven times the rate inside the city. Hallsville simply does not participate in that pattern.
What Hallsville's Fuel Mix Means for Your Equipment
A 63.9% natural gas town is a furnace-and-condenser town, not a heat-pump town by default. The replacement question here is which gas furnace, matched to which air conditioner, inside ductwork that may or may not support it. Three things we check on nearly every Hallsville quote:
- Venting. Going from an 80% furnace to a 90%-plus condensing furnace changes the venting entirely — PVC out a sidewall instead of the existing flue — and can orphan a gas water heater that shared that chimney. Planned before ordering, not discovered on install day.
- Return air. The pre-1980 third of Hallsville is frequently short on return. A more powerful blower fighting an undersized return runs high static pressure: noisy, inefficient and hard on the equipment.
- Backup heat on the electric side. For the 35.6% on electric heat, local normals of about 5,024 heating degree days and 1,248 cooling degree days, a January low near 21°F, a July high near 88°F, 16.5 inches of snow and 41.43 inches of precipitation put you right where an air-source heat pump needs a cold-morning plan.

Which Utility Serves Hallsville — and Which Rebates Apply
Hallsville is served by an electric utility other than Boone Electric Cooperative. That single fact rules out both rebate programs people ask about:
- Boone Electric's rebates don't apply here — the $750-per-ton geothermal and $300 dual-fuel rebates are for co-op members. That page also explains how to identify your utility.
- Columbia Water & Light rebates don't apply either. They require that you "be a City of Columbia Utilities electric customer." A Hallsville address is not — though the Columbia rebate guide is worth reading if you own property in the city.
- The federal credits are gone. Sections 25C and 25D both ended for property placed in service after December 31, 2025 under Public Law 119-21 — details here.
Always verify by looking at the utility name printed on your own electric bill. Service territory around Boone County does not follow municipal boundaries cleanly, and we will not assert a rule we cannot back up. If your property sits in unincorporated Boone County rather than inside Hallsville's limits, a building permit is required for HVAC installation or upgrade — Resource Management, (573) 886-4330. We pull the permit either way.
Around Hallsville
Hallsville sits about 13 miles from Columbia on MO-124, with Route B and Highway OO feeding into town, and is served by the Hallsville R-IV district. Just outside town is Mount Zion Church and Cemetery, an 1863 Civil War battle site listed on the National Register of Historic Places.
MO-124 also runs west to Harrisburg, where 46.2% of homes heat with propane — about as different from Hallsville as two towns that close can be. We also serve Centralia, the most gas-heated town in the county at 70.2%, and Sturgeon, where the median home dates to 1958.

Hallsville HVAC FAQs
What do most Hallsville homes heat with?
Natural gas. In Hallsville, 63.9% of occupied homes heat with natural gas and 35.6% heat with electricity. Notably, zero occupied Hallsville homes report LP or bottled propane as their heating fuel.
How old are Hallsville's homes?
Hallsville's median home was built in 1997, but the town is split into two distinct groups: 46.3% of its housing was built in 2000 or later, while 33.0% predates 1980.
Do Columbia Water and Light or Boone Electric rebates apply in Hallsville?
Generally no to both. Hallsville is served by an electric utility other than Boone Electric Cooperative, so the co-op's $750-per-ton geothermal and $300 dual-fuel rebates do not apply, and the City of Columbia Water and Light rebates require you to be a City of Columbia Utilities electric customer, which a Hallsville address is not. Confirm by reading the utility name printed on your electric bill, and call us at (573) 204-6161.
How far is Hallsville from Columbia, and do you charge a trip fee?
Hallsville is roughly 13 miles from Columbia and sits on MO-124 with Route B and Highway OO feeding into town. We treat Hallsville as part of our regular service area and answer emergency calls there 24 hours a day with no extra fees for nights, weekends or holidays.
Should I add air conditioning to a Hallsville home that only has a gas furnace?
Often yes, and in Hallsville it is usually straightforward because the gas furnace already provides the blower and the duct system. Adding a matched condenser and evaporator coil is the common path. If your ductwork is from the pre-1980 third of Hallsville's housing, we check static pressure and return capacity first, because a new condenser cannot fix a duct system that cannot move the air.
