Overview
No Cold Air? We Answer Live and Roll Out
A dead air conditioner in a North Louisiana heat wave is more than an inconvenience — it's a real risk. When the outside temperature pushes into the upper 90s and the humidity makes it feel hotter, an un-cooled house climbs fast. That's genuinely dangerous for infants, older adults, and anyone with heart, breathing, or other health conditions, and downright miserable for everyone else. Mark Johnson & Sons treats a no-cooling call as urgent, day or night, and has since 1997.
Our phones are answered live 24/7 by a real person — not a machine, not a next-morning callback queue. We dispatch a licensed, background-checked tech fast, usually on-site within 60 to 90 minutes, and the trucks carry the parts that fail most in the heat. That means most emergency calls get diagnosed and cooling again in a single visit, with a flat-rate price quoted before we touch a tool.
When a no-cooling call can't wait
- No cold air with the indoor temperature climbing and infants or elderly family at home
- A burning or electrical smell, or a breaker that trips every time the AC starts
- The compressor slamming on and off, grinding, or dead silent
- The system frozen into a block of ice overnight
- Refrigerant or water pouring out around an unresponsive unit
Fixed on the spot in most cases
The failures that strand people in a Louisiana summer are predictable: blown capacitors and burned contactors first, then fan motors that cook under nonstop runtime, low refrigerant from a leak, and coils that freeze from restricted airflow. Our trucks stock all of it — capacitors, contactors, condenser fan and blower motors, and R-410A — so the majority of after-hours calls are cooling again before we leave. If a part isn't on the truck, we source it the same day whenever a supplier is open. Bigger jobs like a compressor or coil get scheduled fast, and we lay out honest repair-vs-replace numbers first.
Flat-rate, even at 2am
No subcontractors, no surprise hourly meter running while you wait, no pressure. You get the repair price before any work starts — even in the middle of the night. There's an after-hours surcharge for nights, weekends, and holidays, and it's built into the quote up front so there's nothing to guess at. Classic Membership customers go straight to the front of the line on a heat-wave day, take 15% off the repair, and get an after-hours discount on top.

The Process
How an Emergency AC Call Works

On the truck
Professional tools, parts, and diagnostics — every call.
Answered live, any hour
A real person picks up 24/7. We ask what the system is doing and whether anyone in the home is at risk from the heat, then prioritize accordingly.
Fast dispatch
A licensed, background-checked tech heads your way — no subcontractors — usually on-site within 60 to 90 minutes. Classic Membership customers get priority placement in the queue.
On-site diagnosis
The tech pinpoints the failure — capacitor, contactor, motor, refrigerant, frozen coil — and shows you exactly what's wrong before quoting.
Flat-rate quote
You get the repair price before any work starts. No hourly meter running in the middle of the night, no pressure.
Fixed on the spot in most cases
Common heat-wave parts ride on the truck, so most emergency calls are cooling again the same visit. Larger jobs get scheduled fast.
