Overview
Every Cooling Job, One Local Crew
Louisiana summers don't forgive a broken air conditioner. Mark Johnson & Sons has kept North Louisiana homes cool since 1997 with the same licensed, honest crew you trust for plumbing — AC repair, new system installation, ductless mini-splits, coil and refrigerant work, indoor air quality, and seasonal maintenance.
No subcontractors. The tech on-site is on our payroll and accountable to the job. Every quote is flat-rate and given before we start — no hourly meter, no surprise upsells — and the $89–$129 service call is waived when we do the repair.
What we service
- AC repair — no-cold-air and frozen-unit calls, run and start capacitors, contactors, condenser fan motors, and compressor diagnostics on every major brand
- AC installation — right-sized 14–18 SEER2 systems, load-calculated, from Carrier, Trane, Lennox, Goodman, Rheem, York, American Standard, Bryant, and Amana
- Ductless mini-splits — single- and multi-zone Daikin and Mitsubishi systems for additions, shops, and rooms that never stay comfortable
- Refrigerant and coils — R-410A leak searches and recharges to spec (not just a top-off) plus evaporator coil cleaning, repair, or replacement
- Indoor air quality — UV lights, media air cleaners, and whole-home dehumidifiers to fight spring pollen and sticky Louisiana humidity
- Maintenance — Spring tune-ups that catch weak capacitors and low charge before the first 98-degree week
Repair vs. replace
If the system is under 10–12 years old and the repair is small, we fix it. Older units, a failed compressor, or a leaking coil on aging R-22 equipment usually favor replacement — and a modern high-efficiency system noticeably cuts summer bills given how hard AC runs down here. You get honest numbers on both, flat-rate.
Emergency AC and commercial
No cold air when it's 98 degrees — especially with kids or older family at home — is treated as urgent, so we answer live 24/7 and dispatch fast. We also service light-commercial rooftop and packaged units on scheduled and emergency contracts. Ask about our Classic Membership: a Spring AC tune-up and Fall heating tune-up for $189/year, plus 15% off repairs and priority scheduling.

Warning signs
Signs Your AC Needs Attention
In a North Louisiana summer, a struggling AC only gets worse. These are the warning signs worth a call before it quits on the hottest day of the year.
AC runs constantly but the house never cools down
Warm or room-temperature air coming from the vents
Weak airflow even with a clean filter
Water pooling or ice on the indoor unit or refrigerant lines
A spike in the electric bill during cooling season
Humidity that stays high indoors even with the AC on
Hard starts, tripping breakers, or the unit won't turn on
Musty smell or hissing and buzzing from the system
System is 12+ years old and needs repairs every year

The Process
How an AC Service Call Goes
On the truck
Professional tools, parts, and diagnostics — every call.
Call answered live
No cooling in a heat wave gets priority. A real person answers, triages the symptom, and dispatches — including evenings and weekends.
Full-system diagnosis
Your tech checks the refrigerant charge, compressor, capacitor, coils, and airflow, then shows you the real fault before quoting.
Flat-rate quote up front
You get the price in writing before work starts. The service call is waived when you have us do the repair.
Repair same day, most cases
Capacitors, contactors, and common parts ride on the truck. Replacements are sized with a load calc, never a guess.
Verified, sealed, warrantied
We confirm the temperature split, check for leaks, register the warranty, and back our labor in writing.

Repair vs. Replace Your AC
When an aging system fails, the question is whether to fix it or invest in a new one. Here's the math we walk North Louisiana homeowners through.
| Feature | Repair | Replace (Central) | Ductless Mini-Split |
|---|---|---|---|
| Best when | Unit under 10 yrs, minor fault | 12+ yrs or repeat breakdowns | Additions, no ductwork, zoning |
| Typical cost | $145 – $1,450 | $4,500 – $9,500 | $3,800 – $8,500 |
| Efficiency gain | None — restores current SEER | Big — modern high-SEER | High — inverter-driven |
| Lifespan | Extends the current unit | 15 – 20 years | 15 – 20 years |
| Our call | Worth it on newer units | Best value on old, failing AC | Ideal where ducts don't reach |
