Columbia HVAC Co. repairs and replaces furnaces, air conditioners and heat pumps across Shepard Boulevard, with 24/7 emergency response and no extra fee for nights, weekends or holidays. Family owned, all brands, residential and commercial — and the permit and rebate paperwork are ours to handle, not yours.
Second-replacement territory
22,150 occupied homes in Columbia — 39.5% of the city's stock — were built between 1970 and 1999, and much of this part of town sits in that band. Houses of that age have usually been through one equipment changeout already. The second one is a different conversation: the ductwork is a known quantity, the electrical service is established, and the real question is whether to repeat what is there or to change the strategy.
What tends to fail at this stage
On the cooling side: compressor windings, contactors, capacitors and slow coil leaks that show up as a system that cools fine in May and can't keep up in late July. On the heating side: ignition components, pressure switches, inducer motors, and eventually the heat exchanger — which we test rather than eyeball. We carry common parts, we diagnose before we quote, and every job is backed by a 100% satisfaction guarantee.
The ducts are usually the cheap win
Before anyone spends on equipment, it is worth knowing what the existing duct system is doing. Returns that are undersized, panned joist returns that leak, and supply runs that were never sealed all waste capacity you already paid for. Sealing and balancing, along with duct cleaning in Columbia, can fix a room that never gets comfortable without touching the furnace at all.
Heat pump, furnace, or both
Columbia heats 53.9% with natural gas and 43.4% with electricity, so both paths are normal here. With a normal January low near 21°F and 5,024 heating degree days a year, a straight air-source heat pump needs a backup plan — which is why dual fuel (heat pump plus gas furnace, switching over on the cold nights) fits so many homes on this side of Columbia. Our heat pump vs. furnace guide for Columbia lays out where each one wins.
What the rebate pays
City of Columbia Utilities electric customers can claim $800 from Columbia Water & Light on a replacement A/C or heat pump rated SEER2 15.2–18.1, $1,200 at SEER2 18.2 or higher, $1,200 for geothermal under 5 tons, and $1,200 for switching an existing home off gas or propane to a qualifying heat pump. Replacement only, application due within six months, final mechanical permit required — we pull it and file the paperwork. Confirm the utility name on your bill, since Boone Electric serves some pockets inside the city, then see the Columbia rebate guide.

Shepard Boulevard HVAC FAQs
How long should a furnace or air conditioner last in Columbia?
There is no single number, and anyone who gives you one is guessing. Columbia runs 5,024 heating degree days and 1,248 cooling degree days a year, so equipment here works in both seasons rather than sitting idle half the year. Maintenance history, installation quality, duct condition and run time matter more than age alone, which is why we test before we recommend.
My air conditioner uses an older refrigerant. Can it still be repaired?
Often yes, but the economics change. Systems built around refrigerants that are no longer manufactured depend on reclaimed supply, so a leak repair and recharge gets more expensive over time. We price the repair, tell you what the charge will realistically cost, and let you weigh that against replacement instead of deciding for you.
Should I replace the furnace and the air conditioner at the same time?
Not always, but often it is the better value. The indoor coil, blower and outdoor unit are engineered to work as a matched set, and pairing new outdoor equipment with an old indoor coil can cost you efficiency you paid for, and the AHRI rating the rebate depends on. If only one side needs replacing, we will tell you that.
What is a dual-fuel system?
A heat pump paired with a gas furnace. The heat pump handles mild and moderate weather efficiently, then the furnace takes over below a changeover temperature you set. With a normal January low near 21 degrees in Columbia, it is a sensible answer for homes that already have gas service and want lower shoulder-season costs.
Do you charge more for a Saturday or overnight call?
No. We answer emergency calls 24 hours a day, seven days a week, and there is no premium for nights, weekends or holidays. Our work also carries a 100% satisfaction guarantee, and we service all brands whether or not we installed the system.
