Overview

The right fix, not just a refrigerant top-off

When a Louisiana summer is running 95-plus with the humidity to match, a broken air conditioner isn't an inconvenience — it's a house that won't cool down until dark, and often not even then. Mark Johnson & Sons gets a licensed tech to your door fast, diagnoses what's actually wrong, and quotes a flat-rate repair before we turn a wrench. We've kept North Louisiana homes cool since 1997, and the phone is answered live 24/7.

Most no-cooling calls come down to a handful of failures: a blown start/run capacitor, a burned contactor, a frozen evaporator coil from low airflow, a condenser choking on dirt and heat, or a refrigerant leak. The difference is knowing which one — and not just dumping R-410A into a system that's leaking it right back out. That's a repair that fails in three weeks and costs you twice.

What we fix

  • Electrical failures — start/run capacitors, contactors, relays, and control boards, the most common no-start cause
  • Motors — condenser fan motors and blower motors, tested under load, not swapped on a guess
  • Refrigerant leaks — R-410A and older R-22 systems; we leak-search, seal, and recharge to spec instead of topping off
  • Airflow & freeze-ups — dirty coils, failed blowers, and low-charge freeze-ups that ice the copper lines
  • Compressors — the big one, where the honest repair-vs-replace conversation starts
  • Every major brand: Carrier, Trane, Lennox, Goodman, Rheem, York, American Standard, Bryant, Amana, plus Daikin and Mitsubishi mini-splits

Repair vs. replace

If your system is under 10–12 years old and the failed part is a capacitor, contactor, or motor, repair almost always wins. A dead compressor, an old R-22 unit that needs a costly recharge, or a third breakdown in two summers tips the math toward replacement — and a newer high-efficiency system noticeably cuts a North Louisiana cooling bill. We give you real numbers on both and let you decide, no pressure.

What Mark Johnson & Sons does differently

Our trucks carry common capacitors, contactors, motors, and refrigerant, so most repairs finish the same visit. No subcontractors — the tech on-site is on our payroll and accountable to the job. You get a photo, a written diagnosis, and a flat-rate price before any work starts, and the service call is waived when you do the repair with us. Ask about our service savings agreement plans — it puts you at the front of the line on a heat-wave day and takes 15% off the repair.

Warning signs

Signs Your AC Needs Repair

In North Louisiana heat, a struggling AC rarely fixes itself. If you're seeing any of these, call before it quits completely on the hottest afternoon of the year.

  • Air is blowing but it's warm or barely cool

  • Weak airflow from the vents even with the fan running

  • Ice or frost on the copper lines or the indoor coil

  • Unit runs constantly and never reaches the set temperature

  • Warm air plus a hissing or bubbling sound (possible refrigerant leak)

  • Loud humming or a click-then-nothing when it tries to start

  • Water pooling around the indoor unit or a clogged drain line

  • Breaker keeps tripping when the AC kicks on

  • Energy bill spiked with no change in how you're running it

The Process

How an AC Repair Call Goes

Mark Johnson & Sons technician testing an air conditioner capacitor at a North Louisiana home

On the truck

Professional tools, parts, and diagnostics — every call.

  1. On-phone triage

    We ask what the system is doing — no cold air, tripping breaker, ice on the lines — and whether anyone in the home is medically vulnerable to the heat. That sets the priority.

  2. Full diagnostic on-site

    The tech checks refrigerant charge and pressures, the capacitor and contactor, the compressor and fan motors, the coil, and the condenser. You get a photo and written diagnosis — the actual cause, not a guess.

  3. Flat-rate quote before we start

    You see the part-plus-labor price up front. If we find a refrigerant leak, we quote the leak repair — not just a recharge that leaks out again in weeks.

  4. Same-visit fix in most cases

    Common capacitors, contactors, motors, and refrigerant ride on the truck, so most repairs wrap the same visit. Cool air back on before we leave.

  5. Test and verify

    We confirm supply-air temperature drop, amp draw, and refrigerant charge to spec, then walk you through what failed and how to keep it from happening again.

FAQ

AC Repair FAQs

In North Louisiana it's usually one of a few things: low refrigerant from a leak, a failed capacitor or contactor, a frozen evaporator coil from restricted airflow, or a condenser so dirty it can't shed heat. We diagnose the actual cause on-site and quote the repair flat-rate — we don't just top off refrigerant on a system that's leaking.
