HVAC, Plumbing, Electrical & Drain Services in Jefferson, TX

Southern Air has been serving homes across Northwest Louisiana and East Texas since 1994, and our Marshall, TX, team keeps Jefferson well covered. AC, heating, plumbing, drains, electrical, whatever the job, our licensed technicians arrive on schedule, quote you a straight price, and finish it correctly the first time.

Few towns wear their history like Jefferson does. Beautiful as those older homes are, they often hide knob-and-tube wiring, galvanized pipes, and HVAC systems asked to do more than they were ever designed for. We’ve worked on enough of these properties to know how to update them without disturbing what makes them special.

Every Trade, One Trusted Crew

Coordinating separate contractors for cooling, plumbing, and electrical eats up time nobody has. Southern Air puts all three under one roof, so a single call gets you a licensed technician, a fair quote, and a guarantee that covers the whole job, not just part of it.

Cooling and Heating Built for East Texas

Summers here are long and heavy with humidity, which is exactly what our air conditioning services are built to handle, alongside heating services for the cooler stretches of winter. When a system starts falling behind, we’ll tell you plainly what’s going on instead of steering you toward a replacement you don’t need. If the air inside feels stale or heavy, our indoor air quality options, from duct cleaning to dehumidifiers, help fix that too.

Electrical Upgrades for Older Homes

Historic Jefferson properties often need more than a quick fix. Our electrician services team handles everything from troubleshooting old wiring to full rewiring jobs, while our electrical installation crew adds what your home didn’t originally have, think ceiling fans, EV chargers, or smart home features. Storms roll through East Texas often enough that a home generators setup is worth having, and we install, service, and repair them too.

Drains That Don’t Give You Trouble Twice

Older plumbing systems tend to clog more, not less. Our team runs drain camera inspections before we start clearing anything, so we know exactly what we’re dealing with in Jefferson’s mix of century-old pipes and newer replacements. That means fewer repeat visits and a drain that actually stays clear.

Plumbing With Respect for the Property

A water heater that can’t keep up, a pipe finally giving way after decades of use, our plumbing services team gets to the source of it instead of masking the symptom. If it’s time for an upgrade, our water heater services team can walk you through tankless options built to last.

Everyday repairs, a faucet that won’t stop dripping, a toilet that runs all night, a disposal that’s quit, get handled by our bathroom and kitchen plumbing team without turning into a bigger project than it needs to be.
