Whether you’re battling a mid-summer breakdown or looking to upgrade to a more efficient cooling system, our certified technicians are ready to help. We provide full-service air conditioning care—from expert installations to fast, accurate repairs and seasonal maintenance—to make sure your system runs smoothly all year.

Air Conditioning Installation and Replacement

If your air conditioner struggles to keep up or is more than a decade old, replacing it with a modern, energy-efficient model can make a huge difference. Our installation team handles every step—from load calculations and unit selection to professional installation and testing—so your new system delivers peak performance from day one.

We install and service most leading brands, including Trane, Lennox, Rheem, Daikin, and American Standard, ensuring every customer gets a reliable, properly sized system.

Air Conditioning Repair and Troubleshooting

When your AC stops cooling, makes strange noises, or leaks water, you need a solution fast. Our skilled technicians diagnose problems quickly and fix them right the first time. We use advanced tools and years of field experience to pinpoint the cause—whether it’s a worn capacitor, frozen coil, or faulty blower motor—and restore comfort without unnecessary costs.

We also provide same-day service whenever possible, because in Louisiana, waiting days for cool air isn’t an option.

Preventive Maintenance and Tune-Ups

Routine maintenance is the secret to extending your air conditioner’s lifespan and keeping energy costs low. Our comprehensive tune-ups include checking refrigerant levels, cleaning coils, inspecting drain lines, tightening connections, and replacing filters. These steps prevent most major breakdowns and keep your system running efficiently through every season.

Our technicians also take time to educate homeowners on simple upkeep—like how to keep drain lines clear and how often to change filters—to help you protect your investment.
