When your AC quits in the middle of a Lexington summer or your heat fails on a cold Midlands night, you don’t want to wait — and you don’t want to gamble on who shows up. Choosing the right HVAC repair company is one of the most important decisions you can make for your family’s comfort, safety, and budget.
MacDavy Heating & Air is a locally owned, family-run company with more than 20 years of hands-on experience serving Lexington, Lexington County, and the surrounding Midlands. David and the team built this business on honest work, plain-language explanations, and treating every home like their own.
We know this area because we live here too — from the lakefront neighborhoods around Lake Murray to the established streets of West Columbia and Cayce. South Carolina summers are long, hot, and humid, which means your system works overtime. We keep it running so you can enjoy life at home instead of worrying about it.
With the median home price in Lexington County now around $325,000, your HVAC system is a major part of protecting one of your biggest investments. We help you get the most from it with repairs that last, upfront pricing, and 24/7 emergency service when you need it most.
From a single repair to a full system replacement, here’s how we keep Midlands homes comfortable all year.
From quick fixes to full system replacements, we get your air conditioning blowing cold again — and keep it that way through Lexington’s long, humid summers.
Gas furnace and heating service that keeps your home warm when Midlands temperatures drop. We handle repairs, maintenance, and efficient new installations.
Expert heat pump repair and replacement for year-round comfort and lower energy bills. We’ll help you decide when to repair and when it’s smarter to replace.
Leaky, aging ducts waste energy and money. We seal, repair, and replace ductwork to improve airflow, comfort, and indoor air quality throughout your home.
A quick look at the local market and climate that make dependable HVAC service so important here.
For Lexington-area homeowners, these numbers tell a clear story. Home values are climbing and most residents own their homes, so protecting your HVAC investment matters more than ever. With summer highs near 92°F and high humidity, systems run hard for months at a time — and most last only 12 to 15 years. Staying ahead of repairs keeps your home comfortable, your energy bills lower, and your system out of early retirement.
