Overview
Why a Heat Pump Makes Sense in North Louisiana
A heat pump is one of the best-matched heating systems you can own in North Louisiana. Our winters are mild with only occasional hard freezes, and that's exactly the range where a heat pump shines — it pulls heat out of the outside air instead of burning fuel, so it warms your home for a fraction of the cost of straight electric strips or an aging furnace. In summer the same unit reverses and works as your air conditioner, so one system covers you year-round.
Mark Johnson & Sons services and installs every major heat pump brand across Ruston, Monroe, West Monroe, Shreveport, Bossier City, and Grambling. The tech who shows up is on our payroll — no subcontractors — and every quote is flat-rate, given before we touch a tool. The service call is waived when you have us do the repair.
What we service
- Air-source heat pumps — Carrier, Trane, Lennox, Goodman, Rheem, York, American Standard, Bryant, and Amana, split and packaged
- Ductless mini-split heat pumps — Daikin and Mitsubishi single- and multi-zone systems
- Dual-fuel / hybrid systems — heat pump paired with a gas furnace for backup heat on hard-freeze mornings
- Core repairs — reversing valves, defrost boards and sensors, run capacitors, contactors, condenser fan motors, and R-410A leak searches
Repair vs. replace
Rule of thumb: if the unit is under 10–12 years old and the repair runs less than about a third of replacement cost, repair wins. Once you're looking at a failed compressor, a bad reversing valve, or a system still running discontinued R-22 refrigerant, replacement is usually the smarter money. We give you the honest math and flat-rate numbers on both — never a scare tactic to sell a new unit.
What Mark Johnson & Sons does differently
Common parts ride on every truck — capacitors, contactors, defrost boards — so most repairs finish the same day. We test refrigerant charge with gauges, not guesses, and we run the system in both heating and cooling before we leave. Because a heat pump runs 12 months a year in North Louisiana's long cooling season and mild winters, twice-yearly maintenance matters more here than on a furnace that only works four months — a dirty coil or low charge you'd never notice quietly drives up the bill and shortens the compressor's life. We catch that before it becomes a breakdown on the hottest or coldest day.
Ask about our service savings agreement plans — it includes a Spring cooling tune-up and a Fall heating tune-up, which is exactly what a year-round heat pump needs, plus 15% off any repair.

Warning signs
Signs Your Heat Pump Needs Service
Heat pumps usually warn you before they quit. If you notice any of these across a North Louisiana winter or summer, get it looked at before it fails on the coldest or hottest day.
Weak or lukewarm air coming from the vents when set to heat
System runs constantly but never reaches the set temperature
Outdoor unit iced over and not clearing during a freeze
Won't switch between heating and cooling modes
Auxiliary or emergency heat running far more than it should (high bills)
Grinding, buzzing, or loud humming from the outdoor unit
Short cycling — turning on and off every few minutes
Warm air in cooling mode or a weak temperature split in summer
Unit is 12+ years old and repairs are getting frequent

Efficient comfort
One system that heats and cools — built for our climate.
In North Louisiana's mild winters a heat pump delivers steady comfort at a fraction of straight-electric or old-furnace cost, then cools all summer. We keep it running right.

The Process
How a Heat Pump Service Call Goes

On the truck
Professional tools, parts, and diagnostics — every call.
On-phone triage
We ask the age of the system, what it's doing, and whether the outdoor unit is running or iced up. If you're without heat in a freeze, we prioritize the call.
Full diagnostic on-site
The tech checks refrigerant charge, the reversing valve, defrost control, capacitor, contactor, and airflow. You get a clear diagnosis before any quote.
Flat-rate quote
You see the part-plus-labor price up front. If it's a replacement candidate, we show you standard and high-efficiency options at real numbers — no pressure.
Repair the same day when we can
Common parts — capacitors, contactors, defrost boards — ride on the truck, so most repairs finish in one visit. Refrigerant and coil work may schedule out.
Test, verify, and clean up
We run the system in both heating and cooling, confirm the defrost cycle, check the temperature split, and leave the work area clean.

Heat Pump vs. Gas Furnace + AC vs. Dual-Fuel
Three ways to heat and cool a North Louisiana home. The right one depends on your climate exposure, whether you already have gas, and how you weigh upfront cost against operating cost.
| Feature | Heat Pump | Gas Furnace + AC | Dual-Fuel (Hybrid) |
|---|---|---|---|
| How it heats | Pulls heat from outdoor air | Burns natural gas | Heat pump down to ~35°F, gas below |
| Fit for our climate | Excellent — mild LA winters | Fine, higher winter fuel use | Best of both, covers hard freezes |
| Summer cooling | Built in — reverses to AC | Separate AC unit | Built in — reverses to AC |
| Operating cost | Lowest most of our winter | Higher when gas prices spike | Low, auto-picks cheaper source |
| Best for | All-electric homes, mild-winter comfort | Homes with cheap gas, existing furnace | Homeowners who want no-compromise backup |
FAQ
Heat Pump Service FAQs
Yes — it's one of the best-matched systems for our climate. North Louisiana winters are mild with only occasional hard freezes, which is exactly the range where a heat pump is most efficient. It pulls heat from the outside air instead of burning fuel, then reverses to cool your home all summer, so one system covers the whole year.
