Heating & Cooling Services
When Was the Last Time You Had Your HVAC System Serviced?
Your heating and cooling system works harder than almost anything else in your home, running constantly through Louisiana’s brutal summer heat and humidity. Despite how much we rely on it, most of us don’t think about our HVAC system until it stops working — and in this climate, that’s never a good time for it to fail.
Did you know that routine HVAC maintenance can extend the life of your system, lower your energy bills, and help you avoid costly breakdowns? By having your heating and cooling system inspected regularly, you can catch small issues before they turn into expensive repairs. At Mark Johnson & Sons Plumbing, Heating and Cooling, our HVAC technicians in Ruston have over 20 years of experience, and we can help you establish a maintenance plan that keeps your system running efficiently all year long.

Our Reviews

“We have been using Mark Johnson Plumbing for a number of years. We have always been pleased with the technicians and the services they perform.”
– James A.
“Hagen came & quickly assesses the situation after Atmos came out & cut the gas off. He was very professional & founds the two problems quickly! Luckily they were not pricey Issues at all. Then (Christopher) Chris Came back Out very quickly to cut the gas back on inside the house after Atmos did outside. Due to COVID they could not come in the house to turn the valves back on which we had NO idea where they were located. We felt SO stupid that we couldn’t handle that but Chris assured us that most wouldn’t!
He was so nice & professional!! I will definitely call Mark Johnson again. ”
– Marion W.
“I was able to get an appointment the next day.
Service was great, fast, friendly, and exactly what was agreed on. They were on time and did I mention friendly? I would recommend this company to anyone who needs quality plumbing work done. Ask for Quinn Wall.
The customer service was awesome from the start as well. Text notifications of who’s coming, when they will be there. Nice job!”
