HEAT PUMP REPAIR, REPLACEMENT & SERVICE 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.
