HVAC Company in Columbia, SC
MacDavy Heating & Air
When your AC goes out in the middle of a South Carolina summer — or your heat fails on a cold January night — you need a company that answers the phone and shows up ready to work. In Columbia and across Richland County, MacDavy Heating & Air is that company.
Founded by David and Amanda Palmano with over 20 years of HVAC experience, MacDavy is a locally owned, family-run business built on a simple promise: honest service, quality work, and no surprises on your bill. From routine tune-ups to full system replacements, every job gets the same hands-on attention.
Columbia's climate is demanding. Summers regularly push into the mid-to-upper 90s with thick, persistent humidity — while winters can drop below freezing overnight. That year-round strain means your HVAC system is one of the hardest-working pieces of equipment in your home, and choosing the right service partner matters.
Whether you are a homeowner in Forest Acres, a landlord managing properties near Five Points, or a business owner in the greater Columbia area, MacDavy Heating & Air brings the expertise and straight-talk you need to stay comfortable in every season.

Columbia HVAC Market Snapshot
What Columbia homeowners should know about maintaining and replacing their heating and cooling systems.
Columbia's brutal summer heat — combined with year-round humidity — puts HVAC systems under constant stress. Annual preventive maintenance is the single most cost-effective step homeowners can take to extend equipment life, maintain energy efficiency, and avoid expensive emergency calls during peak season. If your system is more than 10 years old, MacDavy can give you an honest assessment on whether repair or replacement makes more financial sense for your situation.
