Whether you're renovating a historic Shandon bungalow or building an addition in Irmo, these tips will protect your investment.
Local listings, alphabetical, with a guide to hiring.
Columbia's long, humid summers make air conditioning the most-used system in most homes, and heat pumps are common. HVAC companies here do repairs, replacements and seasonal maintenance; replacement quotes vary widely with equipment size and efficiency.
Listings are alphabetical and are not endorsements. Details were checked against each business's website on September 26, 2026. Listing policy.
In South Carolina, heating and air conditioning installers and repairers are one of the three residential trades, with plumbers and electricians, that must pass an exam for a specialty contractor licence. SC Code §40-59-20 applies it to residential jobs over $500, and a specialty contractor working for a homeowner on a job over $5,000 must also carry a surety bond. Licences are issued by LLR's Residential Builders Commission.
A replacement system is the expensive decision. Compare quotes on the same equipment tier and efficiency rating, ask for a load calculation instead of a like-for-like swap, and get the labour warranty in writing alongside the manufacturer's parts warranty. State law tells local building officials to refuse a permit to an unlicensed contractor, so ask who pulls it. For the rest of the house, see electricians, plumbers and our 10 tips for hiring a contractor.
