When the temperature climbs past 90 degrees in the Midlands — which it does for much of the summer — your air conditioner stops being a convenience and becomes the thing standing between your family and a long, sticky night. Choosing who works on that system is a real decision, and you deserve a local team that treats your comfort and your budget with equal care.
MacDavy Heating & Air is a locally owned, family-operated company with more than 20 years of hands-on HVAC experience across Lexington, Columbia, and the surrounding Lexington and Richland County communities. We handle heating, air conditioning, heat pumps, ductwork, and indoor air quality for homes and light-commercial buildings — with clear communication, honest answers, and no high-pressure sales pitch.
We live and work in the same Midlands neighborhoods you do, from the shores of Lake Murray in Chapin and Irmo to the established streets of West Columbia and Cayce. We know how our long cooling season, humid summers, and mixed winters wear on equipment, and we size and service systems for the way South Carolina weather actually behaves — not a textbook average.
Good HVAC work should pay you back in lower bills, fewer breakdowns, and a home that stays comfortable year-round. Whether you need a quick repair, a planned system replacement, or a maintenance plan that keeps small issues small, MacDavy Heating & Air gives you upfront pricing before any work begins — so the only surprise is how easy the whole thing felt.
From emergency repairs to full system installs, here’s how we keep Midlands homes comfortable in every season.
Fast, reliable air conditioning service — from same-season repairs to right-sized new system installs built for South Carolina summers.
Furnace and heating repairs, maintenance, and replacements that keep your home warm through the Midlands’ cold snaps and damp winters.
Expert heat pump service for the year-round heating and cooling so many Midlands homes rely on, including efficient new-system upgrades.
Duct repair and replacement plus air quality assessments that improve airflow, comfort, and the air your family breathes every day.
A quick look at why dependable HVAC matters so much in the Midlands.
Columbia and Lexington sit in one of the warmer, more humid corners of South Carolina, with July highs near 93°F and overnight lows that often stay above 70°F. That means your cooling system runs hard for roughly five months a year, while heat pumps and furnaces still have to cover cooler winters. In a fast-growing area like Lexington County — home to more than 317,000 residents — that constant demand makes regular maintenance and properly sized equipment the difference between a system that lasts and one that quits during the first heat wave.
