About Columbia, SC - Happy to be your hometown Heating & Air Conditioning Contractor!

Columbia calls itself "Famously Hot," and the summers back that up. As South Carolina's capital, the city blends state government offices, the University of South Carolina, and busy districts like the Vista, Five Points, and Main Street. Historic neighborhoods such as Shandon and Elmwood Park sit a short drive from newer developments in the northeast. Mack Heating & Cooling delivers residential and commercial HVAC services in Columbia, SC, with repair, maintenance, installation, and replacement for air conditioners, furnaces, and heat pumps across Richland County.

Residential AC Repair and Maintenance in Columbia, SC

Columbia summers routinely reach the upper 90s, and high humidity makes those days feel even hotter. Your air conditioner carries its heaviest load from June through August, and small problems grow quickly under that demand.

These signs point to an AC that needs repair:

• Rooms that never reach the set temperature
• A sticky, humid feeling indoors
• An outdoor unit that hums but will not start
• Breakers tripping at startup
• Water leaking near the air handler

Annual AC maintenance covers condenser and evaporator coil cleaning, refrigerant checks, condensate line flushing, electrical tightening, and thermostat testing.

A spring tune-up catches weak capacitors, dirty coils, and low refrigerant before Columbia's first heat wave. Regular maintenance also protects your manufacturer warranty and helps the system last longer.

Residential AC Installation and Replacement in Columbia, SC

When an older air conditioner can no longer keep up, Mack Heating & Cooling recommends a replacement based on a full load calculation. Historic homes in Shandon and Elmwood Park often need special attention to duct routing and equipment placement, and we plan each installation around the structure of the house.

A new AC system helps your household:

• Lower monthly energy bills
• Control indoor humidity
• Avoid mid-summer breakdowns
• Cool every room evenly

Residential Furnace Repair and Maintenance in Columbia, SC

Columbia winters are short but can bring frosty mornings and occasional ice. Gas furnaces remain common in older neighborhoods, and they must fire reliably when temperatures drop.

Contact us for furnace repair if you notice:

• Yellow or flickering burner flames
• The blower running without heat
• Cold spots in certain rooms
• Rising gas bills

Furnace maintenance includes a carbon monoxide safety check, heat exchanger inspection, burner cleaning, and flame sensor service.

Scheduling this service each fall lowers the risk of a no-heat call on the coldest morning of the year.

Residential Furnace Installation and Replacement in Columbia, SC

When a furnace reaches 15 to 20 years of age, a high-efficiency replacement often lowers winter gas bills and improves comfort in drafty older homes. Mack Heating & Cooling sizes each new furnace to your home's heating load and handles removal of the old unit.

A new furnace provides:

• Higher heating efficiency
• Lower winter utility costs
• More reliable operation
• Even heat in every room

Residential Heat Pump Services in Columbia, SC

Heat pumps suit Columbia's climate well, providing efficient cooling in summer and efficient heating through a mild winter. Rental homes and student housing near the university often rely on heat pumps, and heavy use puts extra wear on the equipment.

Our heat pump services cover:

• Heat pump repair for all major brands
• Seasonal maintenance and defrost control testing
• New heat pump installation
• Heat pump replacement for aging systems
• Ductless mini-splits for additions and sunrooms

We test reversing valves, auxiliary heat strips, and refrigerant charge on every visit to confirm the system switches between modes without trouble.

When a heat pump reaches 12 to 15 years old, replacement often costs less than continued repairs and delivers a noticeable drop in energy bills.

Ductwork Repair and Replacement in Columbia, SC

Leaky or undersized ducts drag down the performance of any AC, furnace, or heat pump. Older Columbia homes often have ductwork that has shifted, cracked, or separated in crawlspaces and attics. Mack Heating & Cooling inspects, seals, repairs, and replaces ducts to restore airflow, cut energy waste, and keep dust and humid air out of your living space.

Commercial AC Repair and Maintenance in Columbia, SC

Restaurants in Five Points, offices along Main Street, and retail spaces in the Vista all lose money when cooling fails. A preventive maintenance agreement puts your building on a set service schedule. Our technicians inspect coils, belts, motors, refrigerant circuits, and controls, and we document equipment condition so you can plan ahead.

Watch for these commercial AC warning signs:

• Hot spots in dining rooms or offices
• Rooftop units running nonstop
• Rising utility bills
• Water leaks from ceiling vents
• Loud noises from rooftop equipment

Commercial AC Installation and Replacement in Columbia, SC

Mack Heating & Cooling sizes every commercial system around square footage, occupancy, and internal heat sources such as kitchen equipment and lighting. We install and replace packaged rooftop units, split systems, and ductless systems, and we schedule the work to limit disruption to your business. Our crews also handle removal and disposal of the old equipment.

New commercial cooling equipment helps you:

• Cut monthly utility costs
• Keep dining rooms and sales floors comfortable
• Reduce service calls on aging equipment
• Meet current efficiency standards
